Kind: captions Language: en ketogenics was something it really was transformational and as I discovered ketogenics through you I'm very curious to hear um you no longer feel the same that you did what changed well it's a broad topic I think around that of dietary restriction so I think my aperture has just widened significantly so you have to take a step way back and ask the question how does one what are the ways in which one can change their diet so let's come back to your example in a moment because I think if I recall when you went on a ketogenic diet it wasn't in an effort to lose weight no yeah so let's put your case aside for a moment and instead discuss it through the lens of how most people think about ketogenic diets vegan diets pick your diets it's it's usually some form of energy restriction so I think initially I was like most people are pretty myopic about my views of energy restriction and over time that thinking evolved into saying look there are really broadly speaking three strategies to reduce intake one strategy is to just directly fixate on the reduction of energy intake that's called caloric restriction so bodybuilders are a great example of this right like they really really know how to weigh and measure every single thing they're eating and they certainly understand during an anabolic phase this is how much energy I need during a catabolic phase or cutting phase I need this much and they've got this down to a science and it's really remarkable I mean it but it's a science optimized for the reduction of fat that's right that's right and maintenance of muscle that's exactly right longevity right for anybody so so but but let's be clear like I don't think there's a better example of any type of person on the planet that's figured out how to control intake up and down and to produce a perfect result with respect to that aesthetic MH well said and for most people that's really hard to do um it's hard to do because you can't really ignore it like you can't just eat without thinking you always have to be paying attention to what you're doing but it is the most direct way to go about getting the result you want so that's method one method two says how about I don't pay attention to what I'm eating or when I'm eating um but I pay attention pardon me how about I don't pay attention to what I'm eating or uh how much I'm eating but I just pay attention to when I eat so that's called time restriction people call that intermittent fasting and if I make the window in which I eat small enough um I will reduce energy intake in total so if I said to you you know you can only have one meal a day chances are you are going to lose weight um now people thought that well there must be something magical about intermittent fasting beyond the caloric reduction but that turns out to not be the case it's been tested in several uh studies now and it's clear that if you eat 2,000 calories in one sitting it's no better or worse for you uh at least from a weight perspective than if you eat 2,000 calories spread out of the course of a day it's probably worse for you in another way though which is you're a little more likely to lose muscle mass because you won't be able to get the right amount of amino acids into your muscles I I don't want to derail your point but we are going to have to talk about autophagy cuz I intermittent fast like a fiend great we'll 35 y okay so then we get to the third method of caloric reduction which is the use of what's called dietary restriction so here we pick things within the diet and we cut them out and the more restrictive that is the more likely it is to produce an energy reduction and therefore the more likely you are to achieve the goal of weight loss so the glib example I always give is if you went on the no lettuce diet you would not lose an ounce right right it's simply not restrictive enough if you went on the only potato diet you would lose an insane amount of weight you simply couldn't eat enough potatoes to maintain now the that's not a healthy diet right no one would think that the all potato diet is going to produce an ideal Health outcome but you will lose a lot of weight right so keto is simply a very for a restrictive form of that diet and many people lose a lot of weight on a ketogenic diet because they are limiting so many things right they're limiting so many carbs it's also for many people much more satiating so it actually readily reduces their hunger and so they simply don't want to eat more so they have fewer food choices and they don't want to eat as much but you can gain weight on a ketogenic diet if you eat a lot you have to be careful because you're generally eating more energy-dense Foods on a ketogenic diet and I've seen lots of people blow up on ketogenic diets because they somehow think it's a license to eat as much fat as they want not the case so now let's talk about so so that's that sort of coming to that conclusion made me realize oh well there's nothing really magical about any particular diet when it comes to energy balance but now each of these diets has their own tradeoffs around other metrics of health so for example we talked about the importance of protein protein is I think the most important of the macronutrients I know everybody wants to argue about fat and carbs but I think the the game is one and lost with protein and you know the recommended dietary allowance of protein is unfortunately very low so there's most people are being told to eat 8 grams per kilogram of body weight and that's literally half what you need to be eating whoa yeah that's the amount of protein for body mass that I carry or ideal body mass total body weight hm yeah so if I at 6 foot weighed 250 lb I'm going to be wanting to eat something like 1.6x that in protein in kilograms so yeah so if you were if you weighed if you were whatever 200 lb I would want you consuming at least 16 g of protein and maybe closer to 200 depending on your demand and depending on your age and depending on the type of protein you're getting so a lot of different diets let's pick two that I think one has to be they're doable but you have to be careful about getting enough protein so let's start with a plant-based diet so a plant-based diet by definition you can't have any animal protein so all of a sudden you're doing away with the best form of amino acids you know one could argue that when we eat animals or animal protein it is a more pure synthesis of the amino acids that are coming from Plants right so like a cow all it's eating is plant but you eat a cow or like venison is one of my favorite things right so I'm eating wild venison from Hawaii that only eats grass and yet it's the richest source of amino acids I can sink my teeth into in other words its digestive system its metabolism is doing this remarkable thing I can't do which is turning grass into the richest densest source of protein if I want to go back and eat the grass it's fine but I just have to acknowledge I'm going to have to eat a lot more of it because it's not a great source of protein so the bioavailability of plant protein is about 70% that of animal protein and it's not as rich in the most important amino acids so when we have patients who are plant-based and they say oh do I have to give up my plant-based diet I say not necessarily um and if it's working for you in all other ways other than this then there's a workaround here but the workaround requires you being very deliberate about your protein quantity another example is you so we're going to come back to the case that you just said which is what about people who are imminently fasting do they have to you know is that a bad thing is that a good thing well it depends but if a person is intermittently fasting you're going to see a lot of muscle loss unless they're very thoughtful about their protein intake so you know if a person's intermittently fast lasting 168 you can generally get away with it cuz in 8 hours you can get usually at least three good servings of protein but we have a lot of people who are intermittently fasting and they're only eating two meals no snacks they can't come close to getting the right amount of protein in because you can't have let's just say you're on the 160 gram a day program 80 grams twice in your day is not going to cut it because you can't put 80 gram to work it's too much protein for the body to Peter man this is so different than how I live well no but think about it like bodybuilders are very thoughtful of this right if you look at bodybuilders I thought we debunked all the like six meals a day and you're saying no like I actually do need to break it back up in smaller pie if you're optimizing for muscle mass yes and it can't be too small so this is where it gets really crazy if you're eating really small amounts of protein like 20 grams at a time you're not going to get muscle protein synthesis because the liver is going to the liver basically takes first dibs on the protein and under glucogenesis it's just going to make glucose out of protein so if you just trickle tiny amounts of protein in you're not getting muscle protein synthesis I'm turning it into glucose really inefficient process yeah you're just the liver is turning it into glucose if you eat tons of protein and the limit based on the literature seems to be somewhere between 40 and 50 gram in one sitting okay once you exceed 40 to 50 grams in one sitting the excess just goes into glucogenesis huh wow okay this is very so if you're trying to get 140 g a day you really need to optimize it by 4 * 40 and uh wow okay so amazing this is amazing I'm always game to change uh okay so I'm breaking my protein up 4X 40 if 160 is my goal what period of time do I need to put between them because I would be happy to do that like it I'm I what's your feeding window what do you like to eat when to when man I I usually keep it tight like four 5 hours max okay so if you really want to do it that way then you're going to have to have if I need to well but but but I'm saying like if that's working for you from a weight management standpoint and a total caloric I'm a freak of discipline I will never accidentally gain weight you don't have to worry about that with me what you have to worry about with me is right now I believe that autophagy is necessary to avoid cancer I don't want to die of cancer so I intermittent fast to make sure that I'm in autophagy but there's no evidence that 20 hours of fasting is sufficient to induce autophagy yeah see I thought there was man I thought autophagy kicked in at like 15 16 hours like uhuh but mice will die in three days of not eating well that's bad yeah so in other words like we're just it's apples to oranges we have no I mean do we know where it kicks in for humans no because we don't have biomarkers for autophagy uhuh my intuition which might be as useful as a warm bucket of hamster vomit is that it's probably three to five days three to four days maybe do you do any prolong fasting I don't anymore wow um and I'm not opposed to it like I would probably still do you know if you were diagnosed with cancer what would you do yeah I would probably get back to fasting more evidence-based or just throwing everything at it mechanistic yeah give me the mechanism uh meaning deprivation of growth factors yeah very interesting also selective sensitization of cancer versus non-cancer cells during chemo right so there is some evidence from wter Longo's work that when you're undergoing chemotherapy doing so in a caloric deficit can be beneficial because the cancer cell is differentially and disproportionately stressed by restriction and than the normal cell and therefore you're CU remember chemo like the magic of chemo is not that it kills cells or kills cancer cells it's that it selectively kills cancer cells anything can kill a cancer cell it's how do you kill a cancer cell and not a regular cell so how do you how do you enhance the spread between those two and it might be that caloric restriction is a way to do it and it renders the cancer cell even more susceptible and at the same time that you're hitting with chemo it becomes uh more likely to die at the expense of the healthy cell that's that's the mechanism and there is some data to suggest that that's the case Okay so uh autophagy we know is going to kick in at much long we hope is kicking in at much longer periods uh deprivation can still help with cancer from a growth factor remember you also kick in autophagy with exercise so if you're looking for another absolutely what what is autophagy right autophagy selfing well yes yes yes but what it's occurring in nutrient absence M and there's a great way to induce cellular energy reduction which is exercise when you exercise cellular energy goes down that's why exercise increases kinas activity just as fasting does H so we you you don't want to underestimate the benefit of exercise in tricking the cell into thinking its nutrients are scarce okay then what kind of exercise I'm going to guess it has to be the kind that I hate the most most and if V2 Max is the under the curve revealer uh it's what we were talking about very high intensity period of rest very high intensity well that's how you train V2 Max but that is that what I have to do no because that's only that's that should only be 20% of your cardio volume 80% of your cardio volume Should Be steady state uhhuh and moderate intensity okay the 80% I like that a lot better interesting that's zone two as we call it and that's done at a level where you could carry out a conversation if you had to but you don't want to right that's the that's the litmus test that is a perfect description okay so uh going back to protein so maybe in fact no you're you're saying just flat out the intermittent fasting is probably not helping you at all and if anything it's probably making it hard for you to get protein and spare your muscle uh you need to spread this out you spoke in kilograms which really threw me off that's okay how much do you weigh in pounds uh 185 Okay so 160 to 180 grams per day so four meals at 40 to 45 grams is perfect for you okay spread out over ideally as long as possible and to be clear these don't have to be meals like two of my four 45 gram of protein that's a [ __ ] meal it's not though think about it like what is that 200 calories it's like a chicken breast it's yeah that I mean you don't consider that a meal that's a rounding error um no for me like I'm doing I'll do like I have these venison sticks that are 10 like a little jerky venison bought or made uh they're actually now bought you can now buy them I like that y okay um so each one is 10 uh grams of protein M and 50 calories and I will have five of those as a snack there's 50 grams of protein right there with 250 calories like it's nothing okay what about are they highly processed anything to avoid there no problem because they're made they're made by company that I'm involved in so I mean I love it the most obviously as a guy that only gets involved with things that I care about think are real so it's called Maui Nei venis okay these are um this a type of deer called Axis deer that are invasive to the state of Hawaii and so they're harvested there in the most Humane manner fashionable which is what allows the animal to be completely stressfree so they're harvested by sniper at night under night vision and whoa yeah so if you think about it like harvesting an animal is a very stressful thing thing for an animal uhhuh like if you're thinking about how a cow is harvested yeah even if it has the most um wonderful life you know it's grass-fed it's out in a pasture it's not inside like all of that might be great and it is certainly better than the alternative but the very end of its life is still quite stressful this is a moral thing or does this moral no I believe I believe I believe it impacts the quality of the meat right so think about the cortisol levels that are surging through that animal's body right at the time of its death yeah but from an evolutionary standpoint everything got eaten oh no no I'm not that's not a moral question I'm saying from a health perspective yeah but I'm saying you're a lion the gazelle you're chewing on is freaking the [ __ ] out as you eat it alive so there's no way that can have some major no I think it actually probably has an impact on taste more than anything else um the other thing is it's very hard I mean this is more of an argument of why I love Wild game yeah is Wild game eats the best plants the best feed right so when you go to the grocery store and you're buying you know a regular grain fed steak it's not eating what it evolved to eat like it's you kind of want things that are as close to eating what they evolve to eat and you know for for for deer that's like that's basically grass right so um anyway these things are processed in a way that basically has nothing in them right so you're just I'm just getting pure protein yeah I don't want to derail this but this is really interesting so you snipe the deer at night using night vision goggles so it basically dies in its sleep it dies instantaneous yep dies instantaneously stressfree um and that is so interesting how'd you find out about these guys um I met the founder of the company five six years ago um and we just immediately became friends I became completely fascinated by the problem that they were trying to solve which was how you know the government is trying to eradicate this species um because it is destroying the island so this is a species of deer that was brought to Hawaii in the 1950s for hunting but it had no Predator it was brought from India where its only Predator was the tiger you brought it to Hawaii it had no predator and it has now run a mck so it is kind of destroying three islands of Hawaii are they finding a way to do this sustainably now so that they can keep having them the goal is by 20 30 to have it be sustainable right now they are still not able to do it sustainably in other words right now the deer are still growing at a rate that is too significant Jesus uh head shot yes interesting wow I don't know why I find that so fascinating but that's very interesting okay so back to protein intake right so point is you could have a w prot wake up I'm like oh Chomp Chomp into the not necessarily like I mean again it depends on when you like to exercise for example so so I should exercise fasted is that the point of that um it depends if I'm going to exercise first thing in the morning I do it fasted if I'm going to wait a couple of hours I'll have a protein meal first but it doesn't matter because I've always heard that you've got so much glucose if you're eating and now you're just going to get fat and you never going to lose doesn't matter no so so um I generally prefer to exercise fasted but if the workout is getting pushed till later a couple hours later I'm going to have something before not because I need to but because I want to make sure I spread out those proteins servings enough so at least two of my protein servings aren't meals they're like again the jerky is not a meal it's a snack and then like a whey protein shake again 40 50 grams of whey protein in some you know cashew milk you do would you uh I'm willing to stomach the venison snacks Andor chicken breast Andor eggs eggs yep great cool love them uh so if I'm willing to eat the amount of protein that I need in eggs venison whatever would I still do a protein shake not necessarily no not at all and do you cuz I have developed slowly over time a deep aversion to anything that's processed so I'm trying to get as close to biting into the walking animal as possible absolutely y That's great okay so but you you're not stressed and then you would have like kind of two meals right so I'll probably also have like my lunch would be a salad with chicken breast or salmon and then my dinner dinner is the easiest meal to hit your protein Target right like that's like falling off a lot just because it's typical to eat a steak Chien whatever you're going to have talk to me red meat white meat matter again I think it matters less the color of the meat matters much more the source of the meat matters much more about how that anal grain fed yeah and and how close can you get it to an animal that's in its natural state truthfully it's much easier for me to get wild game that's red meat like I much prefer elk and axis deer both Wild game that either I'm killing or someone I know is killing and it's the wild that's the important yeah it's an animal that's eating in the environment it's it's an animal that's not contained right and the contained is problematic largely because of the diet that we know they will need yep okay uh how much meat how much of your protein comes from meat by percentage um I don't know I'd have to figure it out but clearly the majority H yeah because the one thing I've always I also like Greek yogurt by the way so that's another thing that's a hard left so Greek yogurt has a lot of protein it does actually it's quite high in protein eat it because of the taste probiotics just another way to get protein in diversify a little bit from boredom or diversity matters yeah just some no no just for me diversity matters like I like to mix things up and and it's just again it's just a function of time like maybe I don't have time to make an omelet right now and I'm I got a quick call I got to jump on so I can scarf down a bowl of Greek yogurt with some nuts in it this seems impossible it seems too good no sounds amazing like I feel like the way that I live right now would take a lot more discipline than what you're describing be interested to see if that's true in practice um okay so let's fit eggs into the mix here uh i' love to get an idea knowing that individual there's a lot of individual variability here in fact we should probably talk about saturated fat at the individual level the one thing in my diet I do not at all pay attention to how much saturated fat I eat and go out of my way to consume it but I make zero attempt to avoid it and because I don't check my blood levels nearly enough I am always a little hesitant to push my exact diet onto people um do I need to worry about saturated fat potentially yeah um saturated fat can increase your uh synthesis of cholesterol it can also with enough of it being consumed the liver can sense the amount of saturated fat and basically shut down the clearance of cholesterol meaning the the the bringing of cholesterol into the liver can I quote Peter AA on cholesterol in the book outlive if you haven't read it I highly suggest it he said your total cholesterol number is about as meaningful to dying from heart disease as your eye color that's right so you're bringing up cholesterol so some something matters something about cholesterol matters but not the total number right total cholesterol is again not particularly relevant number apob which is the uh con which is a measurement a laboratory measurement that is the concentration of lipoproteins that carry cholesterol into arteries that's what you should care deeply about but when someone says what's your total cholesterol 200 milligrams per deciliter who cares doesn't mean anything but there is a type of cholesterol that is carried in a certain well so cholesterol for the most part that 200 migs per lit is your total cholesterol is divided into three types of lipoproteins a high each has a different carrier uh no that 200 comes is the aggregation of approximately three lipoproteins high density lipoprotein low density lipoprotein and very low density lipoprotein so if you look at your lab you get you get a blood test done if it's done correctly a lot of them are not but if it's done correctly and they do a direct measurement of LDL cholesterol you will be able to add up the V LDL cholesterol the LDL cholesterol the HDL cholesterol and the sum of those three will equal the total cholesterol so if the total cholesterol is 200 and the HDL cholesterol is 70 and the vldl cholesterol is 20 the LDL cholesterol will be 110 yep and of those three numbers um we would say the most important Insight you could get would be to take total cholesterol subtract HDL cholesterol and that number is called non-hdl cholesterol that number starts to become a pretty good predictor of risk so total cholesterol because those are damaging in some way yeah that's now telling you the total cholesterol content of LDL and vldl and those are the destructive lipoproteins now an even better number is not how much cholesterol is contained in those two things but how many of those two things do you have and that's what's captured by apob can you explain that more so each of those lipoproteins the vldl and the LDL have a protein wrapped around them that protein is called APO lipoprotein b00 which is a very sexy name it's abbreviated apob so if you measure apob because LDL and vldl have one and only one APO lipoprotein b00 on them the apob number is is the concentration of those two particles and the gradient of that the more of those particles you have the incre the greater the probability that those particles are getting into your artery walls got it so the the number of those do matter and so if I just subtract out my HDL subtract your HDL from your total cholesterol you get the cholesterol concentration of those two particles but but and that's predictive of risk mhm but what's more predictive of risk is the number of those particles okay so which a how do you I don't know if it's going to be fruitful but there's something in that math that I'm not following so if I got back my cholesterol count and I look at them I'd be able to tell of my 200 let's say uh 110 are the two that are bad uh but there's some total number it sounds like you're it's a separate measurement you don't you wouldn't impute it from the those CL you just have to go to apob you have to get the apob measured that's right yeah it's another laboratory measurement understood understood that is unfortunately rarely done is it can you just ask your doctor give me an apob measurement absolutely okay it's a relatively inexpensive test it's about depending on the test it's somewhere between and $20 do they not do it because they disagree with you or they just they don't know they don't know what it is troubling very okay uh so in fact we should talk at least briefly about this idea so in the book you talk about medicine 3.0 versus Med medicine 2.0 medicine 2.0 is all about curing medicine 3.0 is all about prevention um how do we I would call medicine 2.0 more about treating than curing okay fair it's largely not Curative right very good distinction uh okay so if you were going to give me the um the little toolkit of medicine 3.0 uh what how would you begin to bundle that like what are the the things that I should be going towards well again to your point so medicine 3.0 really says we've reached the limits of what medicine 2.0 is good for medicine 2.0 is really good at curing uh acute problems M so it's really good at curing um infections traumas acute issues it's really bad at treating chronic problems MH cancer uh you know current heart disease neurodegenerative disease type 2 diabetes it's really bad at treating those things and therefore all it really does is prolong the period of time you have those things and I go through a lot of explanation in the book as to why that strategy is not the right strategy so living longer is not accomplished by living longer with disease living longer is accomplished by living longer with out disease once you realize that you inevitably come to the obvious conclusion that a new type of medicine is needed which must be focused on extending the period of time you do not have disease and that word is prevention which has been bastardized to mean virtually nothing because everybody talks about prevention but it has no meaning right so true prevention has to start very early true prevention needs a set of tools that medicine 2.0 doesn't participate in medicine 2.0 which is the medical system that every one of us who's trained goes through is largely A pharmacologic playbook now you're going to get people who sit here and say are all pharmacology is Bad Medicine is bad no no no that's not true at all pharmacology is wonderful pharmacology has done amazing things in medicine 2.0 and we would want to use all of those pharmacologic tools needed in medicine 3.0 but it's literally you know 1 of the equation where is nutrition where is exercise where is sleep where is emotional health those things are also needed to delay the onset of chronic disease and none of us got trained in those tools so if if a doctor is going to help their patient with those other four tools they're going to have to learn about it outside of Medical Training that makes sense uh okay so if we know what we're trying to do is delay the onset of these diseases you talk about that in the book that basically the thing that centenarians have in common is that they probably were able to delay the arrival of heart disease dementia uh because you say this um cancer that these things are building for oftentimes decades that you can see heart disease in teenagers y uh which is pretty crazy so these are people that have probably delayed the onset of the early symptoms of that for decades more than the people that died say 70 or 80 exactly okay that makes sense so now then I want to get to and we'll stay on cholesterol here for a second so uh you talk about in the book that dietary cholesterol does not equal cholesterol in your body so what does what causes bad cholesterol being the thing that I'm certainly more concerned about so dietary cholesterol is very difficult for our body to absorb it has a bulky chemical side chain on it called an Esther and the only way we could absorb it is if we have an enzyme to cut the Esther off called the deesterified and bring it in we don't have much of that enzyme so most of the cholesterol you eat such as the cholesterol in you know shellfish or eggs you poop out M okay so we should just make sure everybody understands that eating cholesterol has almost zero bearing on your cholesterol levels in your blood that doesn't mean that your diet has no bearing on the cholesterol in your blood but your genes play a very significant role in the levels of your blood lipids so we want to always differentiate between cholesterol and lipoproteins cholesterol is the cargo lipoproteins are the boat H so um the term bad cholesterol doesn't actually mean anything people say LDL is the bad cholesterol that's actually very inaccurate right LDL low lipoprotein is the boat that carries cholesterol and LDL is bad but we should really say LDL is the bad lipoprotein the cholesterol in LDL is the same cholesterol in HDL which people call good cholesterol so you can see why it doesn't make any sense now every cell in your body makes cholesterol so 95% of the cholesterol in your body is cholesterol you made the reason every cell in your body makes cholesterol is because it is one of the most important molecules in the body if you couldn't make cholesterol you would have died in utero um and the reason for it is every cell in your body is wrapped in a membrane and that membrane is made of cholesterol most of the um important hormones in your body testosterone estrogen progesterone cortisol are made from cholesterol so this hormone is absolutely this molecule is essential for life um but not every cell can make enough of it so we have to be able to traffic it between cells so we have to be able to take it back to the liver the liver has to be able to package it back out it has to be able to move around the system so if your body is like a big city the Super Highway of that body is the blood the circulatory system and the circulatory system is made of water so when you cut yourself you know you see red stuff come out but don't let the hemoglobin and platelets and things confuse you it's just water with a bunch of red proteins in it um and fat doesn't mix with water cholesterol is a fat it's a lipid and it doesn't dissolve in water so we can't just move cholesterol around in the blood the way we move glucose or the way that we move sodium or potassium those things are dissolving in water they're called hydrophilic and they move around freely cholesterol is not it's hydrophobic it repels water so that's why we have lipoproteins we have to have these lipo proteins to move the cholesterol in and out of the body and that gets to the point of there are basically these different types of lipoproteins some of them are very high density they have lots of protein and a little bit of fat in them some of them are low density lots of fat less protein and some are very low density virtually no protein and lots of fat or cholesterol and they have different properties and it turns out that the low density and the very low density ones are the ones that are arthrogenic meaning they're the ones that promote the destruction of your arteries okay so something is starting to slowly come into Focus for me so fat in the blood is bad cholesterol or fat which one do you mean I mean fat so when we talk about if if I'm understanding what you're saying correctly there are two times now that fat getting loose has sounded like a problem uh well let's not so so fat is rarely FL floating around the bloodstream for the same reason but if A lipoprotein if the very low density is indicated because it has very little protein and a lot of fat well just when I use fat there what I'm really referring to is triglyceride and cholesterol but they're inside the lipoprotein why do it matter that the ratio of protein to Fat starts getting low it only matters in that that's how I'm describing why they difference in density got it so it isn't that it is fat that makes them problematic so what do they do what's problematic is that the low density lipoprotein and the very low density lipoprotein are the only ones that seem to make their way into coronary artery walls or artery walls in general and they have the potential to get stuck in there so the high density lipo protap thing no we don't really have a great sense of it it's something about apob so HDL high density lipo protein doesn't have APO on its surface it has something called APO a on its surface and when a high density lepo protein goes into the artery wall it comes back out when AN apob particle goes into the artery wall sometimes it comes out but sometimes it stays in there and when it stays in there or gets retained bad things begin to happen the first of those things is it undergos a chemical reaction called oxidation that chemical reaction called oxidation creates an inflammatory signal and that tells inflammatory cells called macroasia or monocytes to come they become macrophases and they eat that oxidized LDL molecule that's what kicks off a devastating Cascade in which the body ironically and paradoxically in trying to fix the problem creates a catastrophic problem that ultimately leads to the creation of a plaque that if it ruptures will block the blood supply of the artery and cause a heart attack you've got the two types that end up basically they have the apob on them apob can get stuck in my arteries once it's stuck in my arteries my body sends a immune response effectively that then ends up creating a problem uh is that Cal ification calcification is the final stage of the body trying to repair the problem okay so think of it as the concrete that gets poured on a melting down nuclear reactor so when you get a CT scan that's like what's called a coronary CT scan to look for calcification the presence of that calcification while by itself not problematic is predictive of something bad that's happened I describe I think in the book calcification is like going through a neighborhood and seeing bars on the windows the bars on the windows are actually a good thing they're going to prevent somebody from breaking in but it tells you what kind of neighborhood you're in yeah okay now that makes a lot of sense going on with my diet one thing that I'm very curious about and there's a raging debate online a cal is just a calorie um where where do you come down on that in terms of the quality of the calorie does it matter U if I'm eating ter like if you agree that the quality of the calorie matters but I'm still undere eaing do I have a problem so the the the calorie a calorie discussion always needs some clarification are we talking about with respect to energy balance are we talking about with respect to nutrition and health are we talking about with respect to satiety and and so we have to clarify which of those we're talking about all I'm talking about ever is longevity so so then a calorie is not a calorie for sure right so in other words if you took a bunch of people and put you know one group of them on 2 200 calories a day of Twix bars and another group on 2500 calories of you know one food only lettuce you know or whatever it wouldn't be 2500 calories lettuce but you know 200 calories of venison sticks venison sticks and another group on 2500 calories of some well-rounded diet that's you know you know blah blah they might all end up with the same weight they might have a different Health Quality and they I would expect it I clearly don't expect the guy on 2 200 calories of Twix bars to live as long as the person on 25 200 calories of good food nor do I expect them to feel the same so if you're totally and by the way they might end up at slightly different weights because of how they feel and while you may in this experiment control only their intake you might not be able to to control their energy expenditure so they might actually expend different amounts of energy because of how they feel so um the the calorie as a calorie debate I think is kind of a silly one because a lot of times people are talking past each other when they're yelling at each other and they don't understand what they're talking about and so you you know we just have to understand are we talking about pure controlled you know calorimetry or are we talking about in your case what you're asking about which is I think more important which is Health we are um innately really really bad at estimating risk and oddly enough makes me wonder about you and race cars so what is it that draws you to race cars do you think you're accurately assessing the risk on that I I I will say you know that's not an unusual question I get asked a lot I I think that I feel safer in a race car than I do in my street car really absolutely I feel far far more frightened in the drive I have to take tonight from here to San Diego because I'm going to be on the 405 and the five and I know that 80% of people at some point on that drive are going to be checking their phone or losing focus or not paying attention I don't know what percentage of them maybe 10% of them are also going to be under the influence of alcohol and uh they pose a infinitely greater threat to me than I I feel like I could ever face in a race car so other than driving what are some just grotesque misjudgments of the risk in terms of behaviors that people do just on a daily basis um I think I think Automotive is is a very big one so yeah good that we got that one first I think another one that people sort of misunderstand is alcohol you know I mean I I enjoy alcohol as much as anybody but I don't think people understand how once you get Beyond one to two drinks like how harmful it is on your liver and it's sort of like Tylenol right like at any dose Tylenol is really hard on your liver but for most of us because Tylenol has no good feeling associated with it we don't really tend to use it more than we should we you know if we have a headache we take it and it makes the headache go away and but but we don't find ourselves like taking four Tylenol every day just because of whatever reason and yet I'm I'm constantly amazed at how much people drink even when there's no apparent reason for it right so so there's always a reason to have a drink right there's there you can always come up with a great reason to have a drink but there's too many sort of blah reasons that people are drinking so I think that um that that to me is an asymmetric and unnecessary risk meaning the pleasure that they're getting from that you know those four shitty Budweisers that they have isn't anything worse the potential downside it's causing in the long run which says nothing by the way of how often I think people do get behind the wheel of their car when they've had a drink in them and if there's one thing I've learned in the simulator it's how even one drink compromises your ability when it matters so I remember simulator a driving simulator yeah so I have a driving simulator at home which is where I do much of my learning um but I remember one day I was like yeah I was going to go drive the Sim after dinner and I had a glass of wine with dinner I remember getting in the simulator and I was like what in the hell is wrong with me here like I am missing every Apex my I'm just a little bit off I'm a little bit off and I realized oh I had a glass of wine even one glass of wine is compromising me um so how many times have I gotten a car having two glasses of wine at a restaurant the answer is tons was I legally drunk no I was well below 008 but if even if I'm 006 I'm legally fine is that still a reasonable strategy right and I think the answer is probably not you think there are dietary things that people are doing that have just an asymmetric risk reward yeah you know I'm probably kind of a a huge advocate for caloric restriction um at least intermittent bouts of caloric restriction so I believe that the short-term discomfort of not eating for days once twice four five times a year going through a cycle like that I think that the shortterm inconvenience of that that is Trivial compared to the potential benefit of of a true fast you know water only fast for some period of time and I still don't know what that minimum is I think it's probably a minimum of three days are necessary to start to get some of the real benefits of autophagy mitophagy and things like that but what's the difference between autophagy and mitophagy um autophagy is the cell eating itself and mitophagy specifically is the recycling of the mitochondria okay um so I think when someone says and I have many patients or friends or family members who have said like yeah that's just there's no way I'm ever going to I could never give up food even transiently I think that's that's that comes from like not not even being willing to give it a shot like what's the emotional hangup cuz you were you used to be literally the epitome of the robotic eater just insanely strict and you said about 3 years ago you were like nope not doing that anymore and I think to quote you exactly I no longer have the intestinal fortitude to eat like a robot so there was something in you that it no longer was worth it yeah that became much harder than what I do today which is so so back then I wasn't doing any Tim restricted feeding I wasn't doing any fasting it was is a pure form of dietary restriction so my my sort of mental model for nutrition is everybody is starting out on one side eating the standard American diet abbreviated as sad which is an appropriate abbreviation and the thing I always tell patients on day one is like look the good news is you can't get any worse than this the only thing if you're starting at the sad the only thing you can do to make it worse is eat more of the sad right but it's like the standard American diet and I don't believe this was deliberate right I don't think there's a conspiracy theory here but just through a lot of bad luck uh has arrived at the absolute worst combination of macronutrients you could possibly imagine like you couldn't come up with a way to confuse someone's metabolism than to combine fats and carbohydrates in the ratios that they are combined in most of the foods that we would eat by default if we were left to our brothers so from there I say look there's kind of two introd Rory moves which are not mutually exclusive but you can pick one or the other the first is time restricted feeding where now you don't limit what you eat you just limit when you eat it and then the second is dietary restriction you don't restrict when you eat you don't restrict how much you eat which you also don't restrict in time restri feeding but you restrict certain elements of what you eat so for those three years that I was on a ketogenic diet which is I mean probably one of the most demanding subsets of dietary restriction um you know I'd pulled that lever as hard as it could be pulled then you move into diets that sort of mimic fasting um which is basically just another way of saying hypocaloric diets for transient uh periods of time and then ultimately even beyond that is fasting just you know water only also for limited periods of time nowhere in there do I include constant caloric restriction so you know reducing by 20 30% your energy intake in definitely I I think the data are pretty clear that that is not a winning strategy there's something about the cycling into and out of catabolic versus anabolic State you're basically Clearing House right you're sort of getting the cells that are themselves defective and hopefully the ones with the most effective mitochondria we'd love to Target those the most for other reasons um what you want to see is the regrowth you want to when you refeed you want to see The Selective repopulation of the better cells the most robust experiments done on this in primates did not really suggest that as the diet got better the benefits of caloric restriction got better in other words the worse the diet the better the benefit of caloric restriction which points us to this idea that dietary restriction should still always be some component of a healthy nutrition strategy meaning like if you're eating like [ __ ] stop eating like sh stop eating you really really if you're if you're committed to never eating anywhere but McDonald's caloric restriction will have a much bigger effect on you positively than you know if your Baseline intake is you know the way you would eat for example that kind of stuff at like the Deep cellular level about where we're going and what this is going to look like is is really fascinating to me definitely not something that I have the kind of grip on even remotely close to what you do but nonetheless seems like if you're um really going to get to 100 at a high level it seems like you're going to have to take that pretty seriously now you've talked a lot about one of the tests that you want to make real is the ability to check for autophagy and to see in the blood um you've thrown out a couple times that this is like a you probably know the people that would be creating this test um and B that it wouldn't be you know it's not measured in the billions so what what would that really take um is it something that could be commercialized and would give people the impetus to put the capital up for it or what does that future look like from a funding perspective again this is not not like the world's hardest problem to crack um but I'm if I'm going to be completely truthful I don't know how commercially interesting it is as a general rule diagnostic tests are not very commercially interesting um my interests are not remotely commercial my interest is in just knowing what to do it's like I want this test to tell me exactly what the right fasting protocol needs to be should I be fasting 3 days a month 7 Days Every 3 months 14 days when once a year like I want to know that and there's no amount of money that would make it worth you know not knowing the answer to that question um wow that's a bold statement well think about it and I'm not to suggest that like money doesn't matter and money you can't do great things with money like I want money just as much as the next person but never at the expense like I don't want anything to get in the way of the knowledge that can drive living longer that to me is such a priority that I would rather be poor but know how to you know live longer than have all the money in the world and lose my health I totally get that but I will say one thing I want to talk about is you said that um one you've said that you think that you eat dysfunctionally even if you don't have an eating disorder which I actually thought was really interesting and then you said that part of why you gave up the robotic eating was you were worried about how it's affecting your daughter's view of food talk about that CU I think certainly in this the movement that we're all going through right now there's a real risk of that that if I had had kids 5 years ago when I was like ter I was shredded I was so myopically focused on everything that went in my mouth and I loved it about myself and I would Rave about how much discipline I had so for sure if I had kids they would have been wildly influenced by how much pride I took in not eating and so yeah do worry what that would have done and I thought it was super sensitive of you to recognize that and change yeah I mean my brother um actually was the he he brought this point to my attention first but he said you know be thoughtful about how you describe your own interactions with food and when you're giving you know your kids input on what to eat or what not to eat try to tether it less to you know body dysmorphic ideas and Trigger it you know Peg it more to Performance issues for example right because those things are still true right if you if you eat well or eat poorly it affects your performance it affects your cognition it affects a lot of things um and if the focus is more on those things then then you know sort of daddy why aren't you eating this because I don't want to be fat well you know that's and and look there's a truth to it like I mean I'm a vain person I I I'm not you know I've come to a place where I've accepted the fact that I can I won't look like I used to look like cuz I'm not willing to put in that amount of sacrifice ever again you and I have the luxury of being old enough to be able to think through that in a slightly uh less emotional way and at least make that make that choice when I think people who are younger um I don't know I just don't know if they're equipped fully with the tools to make all of those decisions I want to ask you about change you have changed a lot in your life like multiple times from starting out and getting your degree in um engineering and Mathematics and then ultimately pulling the first Switcheroo over into to Medicine then leaving medicine and becoming a consultant then going into hardcore research and um doing uh nonprofit work and then now back to Medicine what what has allowed you to constantly make those jumps or what propels you to make those jumps I have been able to internalize something that I think is not innate to most people which is the fallacy of a sunk cost so uh the sunk cost fallacy is something that gets talked about in you know any Econ 101 class right so you've uh you know you're you're building a bridge and the you know the cost of the bridge is $10 million and you're $9 million into it and the contractor says Ah it's going to be another1 million um for many people they are evaluating that based on how much money they have already put into the project and that becomes a very dangerous game because you can't get those dollars back so instead you have to evaluate it from the standpoint of exactly where you're standing at that moment in time and for whatever reason I've I've been able to stand at any point in my life and sort of say I want to do X I'm going to evaluate that only through the lens of how many years do I have left on Earth and not at all through the lens of what have I already put into this um and I think that's just made it easier to do things that on the outside look odd look orthogonal and then to leave medicine um whatever it was 12 years ago that was something that a lot of people came to me and said you got to reconsider this like you've put far too much into this and I just said like look I'm going to do something for the next 40 years I want it to be exactly what I want to do and that's way better to me than saying well I'm going to do something that I don't really really want to do because I've spent the last 10 years doing it which is where I was i' put 10 years into medical school and training um postgraduate training and it was like look that's that's 10 years I can't get back um and it's that's a fraction of the time that's still in front of me so just it just seemed very logical to me to always pursue my Bliss um and also I mean going back to something you said I think we're in a different world now I mean I think the days are long gone of you do one thing for your whole life I mean I think for some people that will be the way to do it and that's that's great but it's no longer so ridiculous to have a career change every five years I don't I don't know what I'll be doing in 10 years but I'd be shocked if it looked exactly like what it looks like today like I think you know if you're not growing if you're not constantly being reminded of how much more how much higher you have to climb um I suspect it's I suspect life becomes a lot less fun what drives you I mean truthfully I wish I could come up with a whole bunch of pleasant you know sort of nice things to say I think in reality unfortunately a lot of my drive is insecurity um that is shocking and I've heard you say that before um and the first time I heard you say it I thought that's really fascinating because you're somebody who gives me insecurity so the fact that you feel insecurity is pretty fascinating and so as a driver in what way does that drive you David Foster Wallace said in in what what is unquestionably my absolute favorite 22 minutes than one could ever listen to which is his commencement speech from 2005 called This is water so and and the first time I ever heard this it didn't resonate with me I needed to hear it a few times before it really resonated where he said if I if if you if you worship power you will forever feel powerless right and and that doesn't really resonate with me because I'm not a power Seeker but I absolutely worship intellect and and when he with the next words out of his mouth are you will forever feel like a fraud I'm like that is so true I find find myself at least on a daily basis thinking dude I hope people don't find out how much I don't know wow and and I wish I wasn't saying that I mean I wish I could I really wish I wish I could say all of my motivations are pure it's all I'm you know I'm Mother Teresa I just want to fix every problem and make the world a better place but the reality of it is like I think a significant amount of my motivation is just this complete desire to not be found out as a fraud who doesn't know stuff I love that for two reasons one I think that and I'll speak very much for myself from the moment I met you I was like this guy [ __ ] with my head like there's just certain people where I'm like I it's hard to feel smart around you so the the fascinating thing is you know to hear that uh that there's some of that driving you um and then two hopefully people listening to this that that um aren't comparing themselves to you but yet are looking at you going this guy is [ __ ] fast fascinating I'm really interested and they have like a warm feeling for you uh that's probably equal parts like oh he's compassionate towards humanity and that's rat and then equal parts like wow he's [ __ ] smart that's you know he's got cool [ __ ] to say and so for them to hear that you can be so um open and honest about oh yeah I have insecurity and um it's low self-esteem that's pushing me forward because they they will look at you and think it impossible that you could possibly have have low self-esteem um which I think is really really good for people to see that that never goes away and one of the things that I've always thought was I'm not going to call it a superpower but something that I've been glad that I have for myself is my motives are always apparent to me even when they're ugly and Petty and yeah I mean there are times where like what's driving me for whatever reason is ugly it's Petty it's um makes me feel worse about myself whatever but at least I have Clarity on what it is yeah I wish I could say I always could see it I don't think I can I think it requires a lot of I I don't think two years ago I could have acknowledged um what I can be much more brutally honest with myself about today what happened that made that I mean you know I've always seen therapists my you know there's been very rare has there been a season in my life where I wasn't sort of searching for some sense of you know why do I feel so tormented and you know one of them said the most insightful thing to me I've ever heard you know your entire life your entire life has been basically driven by um three skills three things that you do um that you're really good at and they're not good things by the way right emotional Detachment rage and obsession wow you those are like the only three tool you are a guy that has a toolbox that has three tools and those are the three tools and she said look you've got a lot of good stuff out of those tools there are a lot of people who get those three tools and they just end up in jail so you've managed to through a lot of luck um you know wind up not in jail wind up as a quasi successful human being a contributor to society a father like you've done some good stuff but she also said you're sort of at the end of your rope with those three tools like you can't get any more juice out of squeezing those things there is no combination of emotional Detachment Obsession and rage that is going to produce anything of value and you're actually now at the diminishing part of the curve so now you're actually you're regressing so you're going to need new tools and you know so in many ways I think that's what has allowed me to go back and say okay well what what is the impetus of that why is the why are these things happening what you know who do I want to be in five years right because I can't fathom what I like I can't fathom being any different in five days so I have to think bigger I have to think of like okay in five years you want to be it's sort of like what we talked about at the outside if if when you're 100 you want to be able to do these things you can back out of that and say this is what you have to be able to do when you're you know 70 or 60 and similarly if in five years when my kids are aged this this and this I want to be this kind of a person and right now I'm not on a path to be anywhere near that in fact I'm on a path to be completely different you know complet different place okay so start backing out what the person who can do those things in 5 years has to be able to do what in a month how would they react in this situation versus how do you always react in a situation people like me who are very good at doing things where harder work produces better results like when that's your playbook and you are now confronted with trying to do something where that Playbook doesn't work it is ego demoralizing right like if the answer is just swim further like all you have to do is just keep swimming don't stop swimming I got it like I that is my book man but if the answer is no you now have to be able to control your emotions in a certain way you now have to be able to as you said recognize in a moment when you have an emotional reaction why it's what it's really about because it's never about what you think it's about it's about something else can you stop yourself in the moment and recognize that that is a new skill and I'm a baby trying to learn that skill and my old trick of just work harder just work harder it fails so in many senses it's like the most intimidating thing I've ever tried to do right what's your process in all this like how are you actively getting better one is just showing up every day right so it's like you know the last time I last week when I was the last time I spoke with one of these therapists I just had a really miserable day I mean I just didn't want to talk to them at all you know I was in a really really bad mood and so part of it I guess is you set yourself up around people who are never going to take your [ __ ] right so you have therapists so for me having these these collection of people around me it's like they absolutely positively don't let me get away with anything you know I guess part of it too is just having really patient people around you because you're going to make a lot of mistakes in this process right so you have to you know in my case I feel very fortunate I have a spouse who is uh you know I I would say more forgiving than probably she should be she believes in the in the sort of like this is what you could be in 5 years this is this is the guy you can be so when someone believes in that they're much more willing to help you when you fall they'll pick you up as opposed to point out that you fell and do you have like a specific vision of yourself that you're building towards or chasing I mean I do um and it's not it's not a professional version of me it's a personal version of me if I get wave a magic wand what kind of a husband what kind of a father am I and the reason I use those two as an example is it's unfortunately the people who are closest to me who always see the worst of me and so most of what I think about is how do you uh how do you show up for those people CU if you can show up as the best version of you for those people the trickle effect is everyone's going to be fine like you will be a great version of you with everybody so it's it's less about how do you show up at the TSA check gate when the person's obnoxious I'm not I don't worry about that that much that that's a relatively easy thing to control but when you're taking out your problems on your kids or on your spouse you know to me that's that's the stuff that's just got to stop and um and if you can get to that to me that's like the that's the hill of the mountain that's like like that's the hill when you climb that well at that point you're going to be treating everybody the way that they deserve to be treated including yourself by the way I mean as you probably know um those of us who are the biggest you know sort of jerks to others are usually jerks to ourselves you're quite aware of how hard you are on other people when they make mistakes do you realize how hard you are on yourself look do you know what your selft talk is when you're making errors and and I started paying attention to it and I was like wow that's really that's harsh that's very harsh that you would that you that you think these things of yourself which again it all CES back to this insecurity and at the outset I I I said um you know whatever five years ago or four years ago 90% of my bandwidth was on like how to not die and today that's only 50% of my bandwidth the other 50% is the whole physical stuff we talked about and then it's this right it's this um what does an examined life mean and is it a life worth living um because you know I I do think we suffer so much in our own heads uh more than we suffer any any other way [Music] um and I don't know the answer to that I here's what I know I know that that's way harder than reducing the risk of heart disease um I know that's way harder than you know addressing that is way harder than fasting or doing all of these other things that are even non pharmacologic interventions that I think can fix all those other things and certainly for someone like me it's harder than you know exercising or being disciplined about all these other things um and I suspect in part because it's less amenable to doing right right the things that we do um tend to be a little bit easier but this is this is tough stuff so I don't know may maybe part of the reason to want to live longer is to just give more Runway to figure this out effectively why would you want to live longer if you're unhappy and that's such a obvious question and yet I am amazed absolutely amazed at how much I interact with people because remember all I do is interact with people who want to live longer that's my job everybody I'm talking to everybody who wants to talk to me always wants to talk about how to live longer how to live better in some way and yet very rarely are they paying attention to this aspect of their life what is their relationship like with themselves how well as you put it do they understand themselves what are their relationships with other people how well are they able to regulate their emotions how present are they what is their sense of purpose what is driving them all these things and if that house is in disarray I would make the argument that living longer is a curse it's not a blessing it's a bold statement but push back on it I mean what's the what's the definition of torture right let's let's play a thought experiment if I said to you Tom I'm going to Grant you immortality in perfect health so it's not going to be like tonius where I let you live forever but you age forever that would be hell no no I'm going to allow you to stay right like you are now you're not going to get one more wrinkle on your face you're never going to get disease would you take it yes I'm not going to give it to anybody else in your life oh yeah I would take that I'm always shocked that other people my wife included wouldn't I would all right so so let's go one step further I'm going to give it no I wouldn't that's so interesting do you know how many people you're going to watch die wait I'm making the Assumption that's what bothers you why wouldn't you take that um well let's come back to me I want to keep going with you for a minute okay so now I'm going to make the I'm going to give you a different experiment we're going to do the same thing but I'm going to put you on a desert island now yep and I'm going to provide everything for you MH so you're not going to have to worry about finding food um in fact forget the desert island I'm going to keep you in this beautiful house yep and I'm going to somehow keep the lights on and I'm going to somehow keep the food coming in but there will be no other human on this planet for you to ever interact with including your wife would you take that can I kill myself no so I have to live forever like that yes that's the first one where just what I know about the human psyche breaking in isolation I I it would be ill advised though God I would want to if you'd let me kill myself at any point I would take it but if I can't it's too dangerous no of course you wouldn't take it right I mean you how it's not in a course for me that is not self-evident and if I didn't understand what happens to the human psyche when it's isolated in in my life where I have been isolated for extended periods of time I have experienced no suffering whatsoever I don't disagree with that but I think the question is yeah what's the longest of time you've been isolated yeah exactly and what does isolated truly mean yeah yeah yeah and if I have input like if you let me keep the lights on and I could have entertainment I've thought a lot about this like uh how much would that help but like let's you saw the movie cast away yeah okay so if I had any glimmer of hope that I could get off that Island I would want to be alive I would want to try and try that's a totally different story right so this is what I'm saying is even the hope that I could one day reconnect I'm telling you there's no hope I'm telling you I'm going to let you live indefinitely in this house all by yourself y okay so that's just an extreme example of one dimension of emotional health which is connection to others and I'm I'm telling you that given everything to excess oh and by the way I'll even I'll even sweeten the deal Tom I'll give you all the money in the world and you can buy whatever you want wow right now buy what oh you could buy Yachts art whatever you want we've we're going to have robots that do everything for you that that make everything and you can't interact with these robots going to say you you complicated the robots are not they're not going to supplant so there's there's everything I could ever want except for you have all the cars all the Yachts all the whatever you're not going to do it if you really stop to think about it you're not going to do it because with no connection to another person it's a meaningless life yep so we could do the same sort of exercise going through all of these different elements of emotional health and I think if people are really being brutally honest with themselves they'll realize that if you you know if your wife hates you if your kids hate you if your you know you're if people around you don't feel good about you and you don't feel good about yourself and you're not you know you don't have a sense of why you're doing what you're doing I think I think it's a I think it's a tough I think it's a tough way to live so it do you think that people asking that question of how to live longer is in some ways not the wrong question but it's just so incomplete that you need to address the emotional side I think it's a very understandable question um I can't speak to others but I certainly through my own experience can understand why one would ask that question and why it's something you would want to grasp on to I mean I think that for most of us the thought of not existing is a little um if not frightening certainly very uncomfortable H non existence is very difficult only on the back side so we all know what non-existence is like try to imagine what you were like before you were born so I don't I it's possible I'm deluding myself it's also possible that I really just see this slightly differently so I have absolutely no fear of not existing if yeah the thought of just not waking up tomorrow only gives me anxiety around ooh did I make sure that I sort of things out for my wife like is she going to be okay like the thought of something bad happening to her I don't like that um knowing that I'm about to die would change my frame of reference so radically that it would make me immediately behave differently so definitely a huge part of the way that I behave is predicated on that I have more time I try to operate knowing that it's certainly not guaranteed I could have an aneurysm and Keel over and dive before the end of this podcast uh I'm very aware of that um the reason that this feels so important to me and the reason that I was so glad you included it in the book is that I think the only thing ultimately that matters is how you feel about yourself when you're by yourself and if you have earned your own respect I think that's hugely important just found it very intriguing that not a lot of people are going to cover that topic in your book and I was wondering if there is if it's just that like hey make sure that that it's worth fighting this hard to stay alive and make sure that you're not just driven by the animal instinct to fight or flight and basically you have a vision of your mortality that you're running away from but you're never like figuring out why you live or is there also a sense of if you're in that state where you're very stressed out you're prone to anger whatever the case may be you're also shortening your life yeah I think it's both Tom and I think that a lot of people are self-sabotaging without understanding why so we have a lot of agency over living longer I mean if there's one thing I hope someone takes away from this book it's how malleable their lifespan is and how malleable their health span is but you have to do things to get that as you pointed out at the beginning of the discussion there is no easy way to do this um there's not a pill or a specific workout or a superfood or a supplement or whatever that's going to make all of this easy it's a lot of stuff that has to be done over a relatively long period of time and your ability to do that is highly predicated on your relationship with yourself and so you know having sort of poor sleep habits poor nutrition habits poor exercise habits on some level has a component or a root in your emotional health and that's not true for everybody but it is true for a lot of people uh I and I see this constantly in my patients right I see patients whose Own Story whose own narrative is partly an impediment to their actions and so they're suffering twice they're suffering in that their failure to take action or their actions that they're taking for example drinking too much are going to actually shorten their life but they're also going to um decrease the joy of their life and the harmony of their life for whatever period they have so let's say that we do everything right let's say we've got meaning and purpose We have dealt with our emotional difficulties we have identified and this is actually something that's really important that I took away from the book you really have to figure out what of the horsemen is coming for you what agent of death from uh family history genetic makeup lifestyle all of that which one is most likely to come and get you I think that's very important it might be worth actually recapping who the horsemen are we've touched on them I think all of them but we didn't name them as like these are the horsemen might be worth doing that um but so you've you're doing all this how long can we live like is it really like we're already there it's like 122 and and I hope you get there my friend and follow the book and you'll get to 122 to or can we actually push this farther based on what we have today I don't see us exceeding the human record for longevity I think to go beyond that would require a technological breakthrough so I would never represent that you know doing everything to the max with respect to perfect nutrition perfect exercise perfect management of the horsemen through all means necessary that that's going to get someone to exceed that level um you know my thinking of this is that you know we might have 10 years of stretch um which is a huge amount if you really stop to think about it right if your you know life expectancy is 82 and you make it to 92 instead in their quality exactly and that's the point right where I'm really confident we have the capacity to change it is on quality MH and you know I said to you everybody comes to me on some level and they want to talk about longevity but when I really probe them what they really mean is Health span they don't care as much about how long they live they really care about the quality at the end of their life I care about both be really honest as do I Health span would be if I don't have that it's all meaningless I totally agree with you um I would pay all almost any price to live longer and so the for instance um the question that that uh you asked like I would even if there was an apocalypse as long as there were some other people even if it killed everyone I knew and loved which would be brutal man like I am I am into my wife in a way most people just are not into their significant other I can tell by talking to them and even that I would if a meteorite hit and it was like your your wife is going to die but you can live I'd be like yeah I want to live so my wife wouldn't though she's like if you die I'm going that's so interest I can't rep my head I mean depends on my kids but but yes if my wife and kids were not on this Earth I wouldn't want to be on this Earth what would happen if God forbid Peter God forbid I don't have kids because partly because I am so afraid of how devastating it would be if they died but if they died would you want to die um I mean again I I hope I never have to contemplate that but if I lost all of my kids yeah I'd have a hard time probably wanting to go on Wow Wow I get it man look it's it is I I have seen people go through it it is an unbearable thing that I can't believe life asks of anybody but despite knowing how bad that hurts and I would not want to go through it I don't know man and and look of course I might get so rocked I'm just saying here from an emotional sobriety standpoint where it is just the thought exercise um I don't understand people's response to be like yeah just take me out but let's go back to I think what's the more Germain point which is um you want quality of life and length of life I hope what comes across really clearly in the book is those are not mutually exclusive and what I really would like people to understand is if you pursue them both you get them both in fact if you just focus on health span if you just focus on preserving cognition having the most physically robust body possible as you age and pursuing emotional health you are guaranteed to get lifespan benefits as well okay so talk to me about the horsemen let's name them so there's four three of them basically account for the majority of death in the uh first world one of them directly doesn't account for that much of the death but but indirectly probably accounts for the most of it in other words it's the amplifier of the other three so the big three are the diseases of atherosclerosis so heart disease and stroke second one is cancer third one is neurodegenerative diseases inclusive of all dementias so that includes Alzheimer's disease uh Parkinson's disease Louis body dementia vascular dementia Etc so those those three really they they show up a lot on death certificates they kill a lot of people the fourth one is more of a spectrum it's not a single disease but it's the spectrum that goes from hyperinsulinemia to insulin resistance fatty liver disease all that metabolic stuff we talked about all the way out to type two diabetes and again not a huge number of people's death certificates as Naf D type 2 diabetes a little bit but not not staggering but when you're on that Spectrum the further you get towards the type two diabetes side of that Spectrum you're just doubling your risk essentially of all the other three Horsemen do you think that metabolic disease is causitive like is basically every non um traumatic death is it Downstream enough no it's it's it's uh it's neither necessary nor sufficient but it is causitive so so you can have causality without necessity and sufficiency so let's take an obvious example smoking is smoking positively related to lung cancer 100% like meaning there there is a causal relationship between smoking and lung cancer but 15% of people who get lung cancer never smoked I don't know the number but many people who smoke don't get lung cancer so similarly metabolic disease is 100% causally related to the other diseases but not everybody who gets met not everybody who's metabolically ill is going to necessarily succumb to those diseases you could die of something else um and not everybody who succumbs to those diseases had metabolic disease okay that's really interesting there's at least one example you give in the book I'm not sure where you put your own story but you scored a six on the calcification uh scale very young 30 something and then anahad Connor who we bizarrely both know you know him way way way way way better than I do but I had the Good Fortune of meeting him um he scored like 126 or some ridiculous thing so is that the kind of example where you guys were both relatively healthy but have this this what genetic predisposition well totally different issues I mean anahad as I wrot about in the book had unbeknownst to him a very elevated LP little a um which is genetic and he was otherwise exceptionally healthy um and is to this day exceptionally healthy but had this genetic issue that was driving you know rapidly advancing heart disease and luckily um you know was caught really early I mean 125 or whatever his calcium score was pretty darn Advanced but to be able to catch that at such a young age uh is is going to make an enormous difference in course correction so had he not had that calcium scan done and acted on it uh there's virtually no question in my mind he would have died prematurely yeah so I was going to ask so if that isn't a driver or isn't being driven by his diet is it purely just genetic look of the draw yes okay so in the book you tell a story of somebody that came to you they had just the worst deck of cards or hand of cards that you could be dealt around uh cognitive decline well as in the they had the worst I mean they didn't have the worst fortunately they had you know a very bad hand dealt to them Visa the risk of Alzheimer's disease so how do you if you get a rough deck hand why I keep calling deck you get a rough hand like that uh what do you do um you start acting as early as possible possible to mitigate the risk so we know what one we we have a really good sense of things that people can do to reduce the risk of Alzheimer's disease and in this particular woman's case I call her Stephanie that's not her real name um we we undertake a number of things uh with respect to sleep stress uh nutrition exercise supplements that we know are correcting certain deficiencies such as elevated homosysteine levels um and unfortunately in her case fortunately because she's so young but unfortunately for many people we don't have pharmacologic strategies yet so we're just I think on the precipice of sort of some Precision medicine ideas so for example in our high-risk patients who have this Gene the apoe4 gene we are using a new test called the c2n test that measures plasma ID and we're using plasma ID as a biomarker for the first time now to track interventions so in other words we are using drugs exercise nutrition Etc to try to lower plasma ID in high-risk people talk to me about drugs like this is one thing statins comes up a couple times in the book I I the only drug I take is an anahist amine and I would stop doing that if I could figure out what it is either in my diet or my environment that's giving me the allergies uh but I've had it across like seven different places that I've lived different states I mean it just doesn't seem to matter um I've had wildly varying diets doesn't seem to impact it anyway so I take an allergy medication um and then I'll sometimes supplement vitamin D but other than that I I just have a real hesitation to take any supplementation whatsoever ever um but you don't seem to have the same fear I have of an isolated compound so you get people on statins if they have early signs of heart disease not necessarily I mean when it comes to managing apob which is the thing we're trying to manage on the lipid side um we have a lot of classes of drugs statins are one class of drug that's one way to lower apob is to use a Statin Statin also happen to have the most side effects of any class of drug that lower lipids in fact all the other classes of drugs that lower lipids have no side effects statins really have the worst side effects by far so you might say well why do we even tolerate statins like why would we even use them we use them because we have the most data for them they are very efficacious though not the most efficacious um and they may have some other benefits that go beyond their apob lowering benefits so all of that has to kind of be weighed and you have to weigh that against the downside of statins which are that a non-trivial subset of people um have at least one of two problems in the presence of a Statin one they get muscle soreness the other problem is paradoxically their glucose metabolism Goes to Hell h u not entirely clear Why by the way but we see disregulated glucose metabolism in a small subset of patients on statins and again we see in a small subset of those patients about 5% muscle soreness so if we have those symptoms or signs in a person on a Statin and we've chosen a Statin as part of the solution in this lipid lowering campaign we just discontinue it and can it reverses like that but when you prescribe somebody a drug do you do that only when it's like they cannot uh address this via diet and exercise yeah it depends so um it depends on several things so certain so exercise has very little bearing on lipids it has no clinically meaningful benefit on lipids has a much better clinical benefit on metabolic health and blood pressure which are also very important in controlling heart disease so we care a lot about exercise because we want to control those other things that drive heart disease the big three by the way are smoking high blood pressure and high apob so um we again we're trying to do all of this in concurrent fashion as opposed to just you know playing lacko on one thing um but nutrition has a relatively um minor role outside of extremes at controlling apob um once a person once you get a person sort of insulin sensitive uh and once you've normalized their triglycerides unless you're willing to go on profound fat restriction it's very difficult to get apob in the levels that we deem appropriate for um true prevention would you rather put them on profound fat reduction or generally not because it usually comes at such a high cost what's that cost uh usually it they end up getting insulin resistant because you're now putting them on a very high carbohydrate diet and they're usually protein malnourished why would that be true so it just is a function of what they're eating so for two years so I used to be 60 lbs heavier to lose the 60 lbs I basically just ate chicken breast and broccoli and while not fun because I was also calorically calorically restricted so hard uh it was fine yeah and if that works that's that's would that be preference though over a drug here's what I say no the answer is no what I say is diet is a way harder problem to get right than drug so let's get the diet right first let's come up with the diet that works best for your metabolic Health your muscle mass your um your sort of fat distribution and your sanity diet is really hard to get right M maybe not for you you're kind of a you know a highly disciplined person but for most of us we want to make sure that we can put you on a diet that you're you're able to stay with for the Long Haul we're not compromising muscle mass we're not compromising metabolic health so if that Diet also happens to produce very low apob because it's highly restrictive in fat fantastic stay the course in my clinical experience taking care of lots of patients that's not the case for most people for most people the diet that produces optimal muscle mass really good metabolic health and is something that they can tolerate for a long period of time it's not sufficiently reduced in fat enough to have a meaningful impact on their lipids and therefore if we want to get apob low enough to really get into major prevention territory we're going to need a drug okay uh uh I'm not sure if it's more enlightening to find out what stack of drugs supplements you take or if based on Horsemen that is likely to kill you I have people on these but I am curious what what do you take are you on rap ay metformin anything like that um I do take rap ay I do not take Metformin um I do take uh a lipid lowering drug I take two lipid lowering drugs so one of them is called ratha it's a pcsk9 inhibitor so it's an injectable drug that um prevents the degradation of LDL receptors on the liver so that's specific very specific so it's a very clean drug has no side effects uh Works incredibly well it's the most potent lipid lowering drug we have did you have a genetic prediliction to something that made this necessary I mean I I just only that I have a genetic pred prediliction to heart disease my family history is abysmal for heart disease so um you know once that came into Focus for me I was very clear that I was going to do anything and everything to at least take that off the table right um and that basically means not smoking not an issue having low to normal blood pressure fortunately not an issue and having physiologic concentrations of apob meaning lowering my apob to the level of a child okay and you are you able to get to that or is that what this injectable is for I use these drugs to do that got it does rap a help with that no so what's Rapa about explain what it does to people um well I I think that's that's a bit of a TBD right now I mean we we know what it does in the on-label use so on label use at rapy which is you know taking kind of a medium dose every single day is an immuno is an immunosuppressive dose and that's how rapamycin was approved in 19 99 by the FDA for use in uh patients with solid organ transplants so when you have an organ of somebody else put into you your immune system naturally wants to destroy that organ so patients who get uh organ transplants kidneys or livers or hearts or things like that they have to be on a cocktail of drugs to suppress their immune system specifically their tea cells which are the um uh cells that would normally be going after viruses but now they're going after the organ so um that's nothing to really do with how Weir we're thinking about rapy as we're thinking about rapy through the lens of what's called gero protection which means you don't really have a very specific disease you're treating you're more broadly targeting the process of Aging at the cellular level and there um based on a lot of animal data that's very compelling it appears that Romy does indeed provide jro protection um but it's very unclear as to how to dose it to get that um and how you dose it in a mouse probably isn't how you should dose it in a human but we don't really know um so if we don't know why am I doing it yes yeah I guess I I'm I'm I'm steeped reasonably well in the literature and I have a strong enough conviction that the way we're dosing it for this purpose has a much higher probability of being valuable than not but I'm going to be very quick to abort in the presence of new information just as information that you see in the literature in your blood both all of the above new studies coming out you know there's a very important study coming out in three years um called the Aging uh the dog aging project I believe it's called yeah yeah Matt kin y I had him on the show yeah so so very interesting so if I remember right from uh talking to him basically we trying trying to get out of mtor more or less which is my big fear with my diet because I'm I eat so much I mean so much has changed my mind since reading your book but I eat so much protein animal protein specifically I imagine I'm in mtor all the time and so it was is tempting to try rap a but is that what's really going on uh not really I mean well yes Rapa is is an inhibitor of mtor that's that's how the drug Works um but it's not when you eat protein the activation of mtor is relatively short so but if you're eating it all the time wouldn't you then presumably just constantly be stoking that fire not necessarily I mean even if you eat like I do which is no intermittent fasting there's still 14 hours a day I'm eating nothing right so um and again amino acids do not stick around very long in circulation so you know you're they're coming on they're stimulating mtor and then they're gone um if if if mtor if if um ramy's benefit is through mtor inhibition specifically um it's probably more through the inhibition of chronic elevation okay and who knows there may be tissue specificity it may be more about what it's doing in one part of you know in one tissue versus another might not be in the muscle it might be in the liver um there there are a lot of unanswered questions here which is why I think the work Matt is doing is really important it's very difficult to imagine immortality when you untether and uncouple the uh not dying part with the preservation of Health span so specifically cognitive Performance and Physical performance and I think more about those things now than I probably ever have before I think a lot about sort of the physical stuff so what does it really mean to be a 100 but function like a well Todo 50 to 60y old and and even if you're alive how happy would you be I mean it would be I think for many people it would be quite frustrating or you know if you had grandkids or great grandkids and you couldn't play with them or you couldn't tie your shoe I mean we actually use tying a shoe as one of the metrics to evaluate sort of flexibility and and certain physical performance so most people our age don't think of tying their shoe as a physical performance and yet when you would start to lose those things I think you'd have a radically different view of you know what am I doing but do you get there and and look perform and feel like the way we imagine a 60-year-old today a fit 60y old cuz I know some 60-year-olds that are just amazing right so how do you how do you take that to 100 and what would have to happen for us like what do we really need to figure out is this a um flexibility problem joints burning out problem ATP problem like what what's the big good question um so far my my exploration to this topic has has suggested a couple of things so one is we do tend to disproportionately load joints over muscles so in an ideal world you would want to figure out a way to exercise where you can maximally load the muscle while minimally loading the joint so there is a lot of joint failure that becomes problematic I mean and I'm separating the obvious which is there's just too many people who aren't exercising enough or correctly at all and so they're just sort of withering away but if you come at this through the lens of okay well what if we're dealing with a subset of people who are committed to figuring out how can they exercise best in many ways it's just a lack of specificity right so most people who exercise can't actually tell you why they're doing what they're doing the 99.9% of us who don't get paid to play a sport and who aren't even really competing at a serious level outside of the professional ranks I don't think we know what our sport is and I think the sport should be being the most Kick-Ass 100-year-old that ever lived so what would that look like like what does it mean to be the most kickass 100y old and I think you have to then reverse engineer all of the things one should be able to do so a kickass 100 year should be able to I I don't know I'm making this up because I haven't fully codified this yet but they should certainly be able to carry two 25lb bags from a grocery store they should be able to lift a 30 or 40 PB bag over their head to put it in a you know compartment of an airport of an airplane they should be able to have a you know 25 lb little terror run at the them you know either great-grandchild dip down into a squat and grab them and pick them up they should be able to jump down on the floor and play with cars or dolls and stand up without assistance and if you start to map out the 25 or 35 things that becomes a new decathlon so instead of saying the decathlon is running this distance jumping this far swimming this far it's like great those are kind of arbitrary now we're going to come up with like real world things that you have to be able to do when you're 100 if you want to live what I would describe as potentially uh more fulfilling physical life to enjoy the fruits of having not died by that point in your life all right so how do we build towards that I love this by the way like I always tell people I want to live forever I'm well aware that as of right now I'm going to die um so my thing is how do we stay alive long enough to give time for these step function breakthroughs to happen so what do I do like what are the things that I train or the hormone replacement therapies that I need to go what do I need to watch what are those things that I should be doing taking a step back I would say 3 years ago 80 to 90% of my energy went into how to not die which basically strategy yeah which is tan amount to how do you delay the onset of chronic disease so the mathematical equivalent of longevity from a lifespan perspective is creating a phase shift in disease onset if you want to live to 100 it basically means you have to delay the onset by about two decades of every major chronic disease so it doesn't mean you can't get cancer or heart disease or any of these other things but you better figure out a way to get them 20 years after the average person gets them I would say now that occupies 50% of my brain wave energy whatever and much more time goes into two other things which is how to minimize suffering which is kind of an emotional problem and then how to be this Kick-Ass 100y old so to the latter um the model I have in my mind is that of sort of Bruce Lee Bruce Lee sort of looked at each and every discipline of martial arts including boxing and wrestling and things like that and said let me extract from each of these disciplines that which I believe is useful discard those that I think are useless and create a perfect fighting form that is truly geared towards self-defense so it is not a sport there is no tournament there is no rank there is no belt there is no Sensei it is can you handle yourself in a life or death situation my wife Lisa struggled profoundly with her gut health and experienced debilitating stomach pain so I focus my energy on learning everything thing I could about the human gut viome is on The Cutting Edge of this growing area of study with their atome gut intelligence test just 2 to 3 weeks after sending in your sample you can see your results on 20 Integrative Health tests that measure your inflammatory activity metabolic Fitness and the health of your gut lining as a special offer to my viewers viome is offering $110 off your test just go to trome.com impa and use code impact to get the $110 off if I go to a yoga class or if I do a pilates class invariably there's something in there that I think is really valuable and truthfully there's a bunch of stuff that I'm like I don't need this this is just if I had infinite time this would be fine to do but I don't have infinite time so now you apply a constraint to the problem which is not only do you want to be sort of the best 100y old imaginable what if you're only willing to spend 10 to 12 hours a week preparing for that and so you say okay well so there's a new sport which we Define some of the parameters of that's your new Olympics and that Olympics is 50 years from now how will you train for it if you're only willing to spend 10 to 12 hours a week training for it well my guess is you will take a lot of things from various disciplines discard a lot of things and sort of have to build a very bespoke routine around it that will involve the maintenance of muscle mass joint Integrity flexibility uh functional movement B bance things that we don't even really think about anymore how many times does someone who's 90 fall because they've lost their balance and it's that fall that ultimately leads to their demise how much of that the balancing do you think is neurological and how much is physical they're just not doing enough physical [ __ ] to figure out to maintain that my guess is it's probably both there's a stability issue that starts to go away as you age also the consequences of a fall become much more apparent so um it's probably not just the case that someone who's older Falls that much more it might be that the the severity of the injury becomes so much more severe so right now if I were walking here and I tripped on that stair and fell you know maybe on a really really bad day I break my wrist but most likely nothing happens uh in 50 years if I do that same thing the probability that something bad happens is going to be much greater yeah um but that said I already can tell my balance is not what it was when I was 20 MH when I was 15 I mean I used to do I used to be able to do this exercise when I was 15 where I would do a with blindfolded I could do a single leg squat with the with the non- squatting leg straight out in front of me so I could go all the way to the floor and all the way up arms crossed blindfolded I could do 20 each leg I can't do that once today with my eyes open so admittedly I'm nowhere near as strong as I used to be so there's a strength component but I also just clearly lack the balance and so so the question is now maybe that activity is a bit over you know that's just unnecessary um and again I don't know what the answer is I don't know if this means I need to get out there and practice on a tight RPP or something like but there's there's something that needs to be done so every time I do some sort of really wellth thought out workout I find myself thinking God like some percentage of this is so essential all of those things need to be put into this new discipline this new sport which is called for lack of a better word being a kick-ass 100-year-old I definitely like the sport now one thing that I found really interesting is so people complain a lot about lower back pain talking about unnecessarily loading the lumbar um I found that if I don't deadlift my lower back hurts not if I do deadlift now some of that probably that I have decent form it's certainly not exceptional but I have decent form I know how to avoid injury um but it is so weird to me that doing nothing will end up causing me pain in my lower back but if I'm religious and I'm doing it you know once or twice a week every week I feel Bulletproof the advantage of deadlifting and squatting to me is uh they reveal all of your errors in movement right like they are I don't know how to describe it but you can't hide from those movements like you can't take bad form into those things and not get revealed right so I like that the question is is it an unnecessary risk right am I one bad deadlift away from doing something stupid where and and again I you know I'm as empathetic and in love with those movements as anybody but I also don't know if I need to do that to be the best version of myself as a 100-year-old so the stuff I've been doing for the last four to 6 weeks um I basically haven't had more than 155 lbs on my back in six weeks and but by changing the form of what I'm doing and making everything a single leg movement uh so a lot of curtsy squats lateral lunges incredibly strict lunges where you are so specifically loading the the front leg glute I got to tell you like I'm not and then doing a lot of single leg body weight squats but with meticulous form so that I'm fully loading the glute not overloading the quad which is my absolute common Mistake by doing these things I don't feel like I've lost a step but I absolutely know I'm loading myself less now the question is does that matter and I don't think I know the answer yet so unfortunately I feel like I'm still too early in this process to know what the Finish Line looks like and there's other problems that we haven't even touched on right like what V2 Max and what aerobic base are necessary as a minimum threshold yeah talk to me about that CU I hate cardio but it's one of those if I have to to have the kind of longevity then so be it and and and the term cardio is itself so confusing right because even if you think of what is V2 Max I mean most people think well that's really a a heart lung issue it's actually not it's more of a muscle issue interesting because that's where the the bottleneck is not in how much oxygen can you get in your lungs the bottleneck is how much can your muscles utilize so when you look at you know the winner of the tour to France or you know the gold medalist in you know cross country skiing or the person who wins the Boston Marathon like when you when you look at the most extreme endurance athletes who have these very high V2 Maxes what's unique about these people is their muscles which is counterintuitive because they're usually very slender individuals but their muscles are so efficient at aerobic metabolism that they are able to extract so much oxygen out of blood when you and I you know are at our maximum capacity we're still breathing out you know 80% of the oxygen we breathed in so it's really not a gas exchange problem it's a muscle problem that said V2 Max is a very specific energy system that probably gets a little more credit than it deserves so what are the Alternatives well um so so V2 Max is really as its name suggests it is so the definition is what is your maximal extraction or utilization of oxygen the way to experience what that is is go out and run for 4 minutes as hard as you possibly can yeah that is that Energy System but there are other Energy Systems right there are in cycling we talk about seven different Energy Systems but again you can really simplify this and say there's sort of the Energy System we're in right now which is the smoking and joking Energy System at the far under end of the spectrum is this neuromuscular area where you're basically doing the most explosive movement imaginable for you know 10 to 15 seconds and I suspect that for each of those Energy Systems there's an there's a minimum threshold that you'd want to be above as you age so ways that you could test that would be I mean any even someone our age probably knows if you carry two bags of groceries up four flights of stairs most people are feeling that very few people get to the top of that fourth I know that because that's my apartment it's on the fourth floor so like in New York I'm always that you know I'm always paying attention to like what will happen when when the day comes that this is not pleasant like when I'm deciding I have to take the elevator up these four flights of stairs um and so if that becomes the minimum threshold then you and and that you want to be there at 100 then you need to be there at 60 and you need to be there at 50 and you need to be there at 40 and so I think part of it is just defining those things and that determines then what's the level of training you need to do but I do think in this current environment of everybody loving high-intensity interval training which I love just as much as the next person that's really only training one Energy System and I think you if you ignore these other Energy Systems you're you're sort of not fully optimizing around your performance Translating that to this new sport this 100-year-old Kick-Ass sport I think it's just going to require a little more thought I'm talking to orthopedic surgeons and saying okay talk to me about the injuries that are killing people um because there's two types of Orthopedic injuries that kill people there's fast death and slow death so fast death is patient falls and you know within a day or so is dead from whatever the injury was so they you know break their femur or they have a fat embolism they're dead or they fall and they hit their head and they you know have a cerebrovascular accident they're dead um but then there's also the slow deaths right and these ones are to me far less talked about but in many ways more tragic um so so one of my closest friends his father died recently um 89 years old complications of Alzheimer's disease he'd been diagnosed eight months before he died so in some senses you could say well the good news is he was spared he and his family were spared a lot of suffering because you know he's diagnosed in January he died in August but when I went home for the funeral I was sort of struck by how difficult it had been for him since he was 81 the two things he loved most in life which were Golf and tending to his yard he couldn't do because of more chronic Orthopedic injuries so he spent the last decade of his life kind of watching TV and to me that's the thing we have to be able to avoid and uh you know for me I don't know what it's going to be when I'm 100 but I know that today if I had to start saying if someone said well you can't drive a race car and you can't shoot a bow and arrow and you can't lift weights doesn't doesn't matter how heavy it is right but you can't do these movements or you can't lay on the floor to play uh if i s if I had to give those things up I'm not sure how much I'd want to kick around and so talking to these orthopedic surgeons is giving me a real insight into where those failure are coming from and the single most important Insight I've gained from them is something you alluded to at the outside which is just joint overload you know so much of what we do is even while trying to be good meaning trying to exercise all these things is just disproportionately taking on rest so for I give you one silly example right a military press is there a time and a place for a military press absolutely does it have any role in my life absolutely not right why not first of all I don't need to load my spine in that way and if I could get 80% of the benefit that I get out of a military press by doing loaded activities below my shoulder line below my neck and using more static loaded Mo movements above and that gives me 80% of the benefit at 20% of the risk that's exactly the kind of compromise I'm willing to make and yet I don't think we're applying that level of risk reward to how we exercise cancer I don't know if people are more afraid of Dementia or cancer but both of those are pretty terrifying from in terms of ways to go out uh with cancer we've I forget how long we've been the war on cancer we've made precious little progress are we barking up the wrong tree like what what is it that either makes that so hard like if we know what it is why is it so hard to deal with and if we don't know what it is why do you think that's evaded our eye for so long well it's it's a really good question um you're right that we have made scant process in the the most important metric of cancer which is overall survival so if you think about it for everybody who gets cancer we should be asking the question How likely is it that they will not die of the cancer that they just got um another way to think about that is How likely are they to be alive in 10 years if you're alive in 10 years after getting cancer that cancer is unlikely to be the thing that kills you um and by that metric we've only made made about a 5 to 8% Improvement in 50 plus years wa and that Improvement has been largely in some very specific cancers so that's not like across the board we've gotten a bit better it's like no we got a lot better in a couple of cancers namely leukemias and certain lymphomas couple of other esoteric cancers like testicular cancer and aside from that we haven't really gotten better h uh now very recently there's some exciting news that does seem more applicable to a slightly broader array of cancers which is the a form of therapy called immunotherapy so unleashing the immune system to fight Some solid organ tumors has also proved to be and some leukemia lymphomas has proved to be quite promising but we still haven't figured out a way to unleash that against every Cancer um even though in theory it should work right every Cancer should have at least some mutations on it that the immune system could recognize as non-self and we know for certain that 80% of them do in fact 80% of cancers solid organ cancers so these are the ones that are killing the majority of people right so breast cancer prostate cancer lung cancer colon cancer Etc um 80% of those cancers have what are called novel neoantigens on them meaning they have antigens on them that are novel to the cancer and recognizable by the host's own immune system the problem is there aren't enough te- cells to recognize it to mount a sufficient immune response so the real challenge of cancer therapy today in my view is going to be enhancing that problem that process rather in other words I think most of the attention on cancer should be on how do we create more reactive antigens in cancer and how we enhance and extend the longevity of te- cells to attract that um so I'm I'm actually surprisingly more optimistic now about this than I was even when I started writing the book uh because of what I'm seeing with a class of drugs called checkpoint Inhibitors and also for um what I'm seeing with interesting clinical trials where we're seeing the pairing of checkpoint Inhibitors which are immune modulators and conventional chemotherapy drugs which take tumors that are not previously susceptible to this immune modulation but then create mutations that then make them susceptible really clever and cool stuff I I I think I write about a couple of examples of that in the um cancer chapter so um it's it's easy to be sort of pessimistic about cancer because of how poorly it has gone for the past 50 years but I think the next 10 years look a a lot better than the last 50 H because of things that are already in motion yeah because of these processes that are in motion so if you got diagnosed with cancer what would be like step number one you what kind of cancer is it uh is it one that responds to immunotherapy is there like a protocol that you would walk down no it would be entirely dependent on what the cancer was but you know so that gets to kind of step two of my thinking on cancer which is uh is the the unequivocal unambiguous understanding that your odds for treating cancer go down the more cancer cells you have in your body so detecting it sooner in the book you talk about you for your patients you lower the age of colonoscopy we do everything much more aggressively so we you know we're we're doing we're doing colonoscopy much earlier much more frequently we're doing how often would you do a colonoscopy oh it depends on the individual I mean in me I do it every three years really yeah and then I do stool based testing in between what do you check in the stool you're looking for fecal DNA so you're looking for DNA of colon cancer yeah interesting how it has its own DNA what are we looking for yeah you're looking for the DNA that's shedding from a tumor tumors have DNA other than it's not my own DNA it is your own but it's mutated I mean by definition every I mean cancer is a genetic disease right so cancer by definition has mutations that render it different from the host cell in a way that's predictable uh yeah that's we know what breaks in DNA yeah we know what's we we're sampling what's normal because we see the abundance of that and then we're looking at what's different from that is there anything abnormal yeah very that's what a liquid biop is how would you do that like the sequencing of that sounds like a nightmare not anymore I mean you can sift through that many samples my God Next Generation sequencing can do this stuff like it's it's simple how many sequences would you have to do in a single feal sample to figure out if there's one like is it a th000 100 10 um I think what maybe a better question is what's the Frequency with of abnormal cells that can be detected in the presence of normal and and and that's a good question I don't know in feal uh I don't know in the feal test I know in the blood test it could be one in a million do you guys speaking of feces uh do you guys look at the microbiome at all no really what don't know what to do with it yet nobody knows what to do with it anybody who says they know what to do with it is probably trying to sell you a supplement that is probably true uh okay so I'm startled meaning look there's no doubt that the microbiome is an is an important part of human health like we're not I'm not sitting here denying that or saying the Earth is flat there's no doubt that your diet plays an enormous impact on the microbiome there's no doubt that you know a course of antibiotics will alter like all of these things are true true but we're still left with the so what question I've yet to see an example of where someone can show me that I have a person in whom I detect a problem I check their microbiome I make an intervention in response to it that I wouldn't have otherwise made that fixes the problem wow I just don't see those examples okay so man this is very interesting and important to my life so I think we talked about this before my wife 7 years ago now I think had a threshold event where she went from having a manageable gut issued to I was legitimately afraid she was going to die her hair was falling out her nails were breaking she couldn't keep anything down she was in agony at times on the floor couldn't be picked up I was just really really brutal she had to do things like swallow cameras colonoscopy endoscopy like I mean she did [ __ ] everything and this was long enough ago 7 years that uh uh a lot of doctors only sort of knew what a microbiome was like they didn't know anything about it they only sort of knew that it existed and so they couldn't come up with any answers and it was only through finally getting her tested realizing she didn't have enough diversity realizing what we're going to have to do to start building that diversity back it was a very long journey of figuring out what the things were that she was responding to um dietary enzymes probiotics prebiotics I mean just like this whole arsenal now may just be oh we didn't actually and and to be honest we don't know which of those things worked and she's said many because she takes like 26 supplements a day or something she's like I don't do I still need to take them all she's like I have no idea so she just keeps doing what she's doing and we don't know the counterfactual in these situations and and I guess what I'm what do you mean by that we don't know what would have happened if you did something different yes very true so that this is the problem with this space is we don't have clinical trials upon which to extract knowledgeable or reliable information why I don't know probably because there isn't enough financial incentive for the industries that typically want to do this right like if you're an unregulated industry which is the supplement industry what incentive do you have to do a clinical trial you don't require it to sell your product all you need is marketing so that's why no supplement company is out there trying to run a clinical trial clinical trials are only run by drug companies because they can't sell their product without a gold standard of a clinical trial so for as much as people want to kind of poo poo drugs and R yayayay supplements they should really be thinking about this in the other way the burden of proof is much higher on a supplement in the sense that we have no clue if it works let alone if it's not harmful at least the FDA for all of its faults and you won't find many people that are more critical of the FDA than I am I think it's on the verge of being a corrupt organization at least it tries to hold drug companies to some level of efficacy and safety it doesn't always do it but at least it's trying at least they're going through those motions no one's even trying to do that with supplements I mean the supplement industry is such a filthy disgusting industry that even though I take supplements I stress more about sourcing those than I would ever stress about sourcing Pharma H okay so in other words you got to be really careful where you're getting your supplements so if I'm using a probiotic which I do during allergy season interesting a probiotic why you know I I live in a part of the world where there are really Wicked allergies and I don't want to get them so I've talked to a few allergists and I've said look what can I do prophylactically during this season in Austin where Cedar fever is out of control and they say well we don't recommend doing immunotherapy until you actually develop the allergy blah blah blah blah blah but a couple of them have said look we recommend this probiotic we think it might slightly enhance you know this element of your immune response and I'm kind of like okay I if there's a 5% chance it works and it's not going to hurt me I'll take the chance because the only thing I'm doing is wasting money but like I don't find that to be a very I mean I do it somewhat reluctantly right it's so interesting to me that the microbiome would play a role in allergies I mean I get it because so much of the immune system's there but it's just it's such a unexpected twist turn of events for me um even just the discovery that so much my immune system resides in my gut was already startling yeah it's it's it I mean again I think the microbiome is interesting and I really hope we get to the point where we know how to manipulate it um are you do you look at the research on that or are you waiting for something more stable to come oh I intermittently do but but I don't follow that research nearly as closely as what I'm following other things so it's it's sort of like like every year I'll go back and do a little dive into it with the team and say okay what is there anything we know today and you know year upon year upon year we kind of come back to the same conclusion which is nothing to nothing exciting to report yet I mean there are edge cases right so feal transplantation obviously very efficacious in some people um do you worry about fmt um I mean there are huge risks associated with it as you know so it's it's it's it's something that should only be done when the risks are justified by the alternative of not doing it yeah we were maybe a month away from me doing feal microbial transplant with Lisa cuz I was just like this is scary yeah understandable but for reasons of they just felt like blood transfusions from like the 70s or something where it's like are they scanning for the right things very terrifying so what would you have done if I had come to you with Lisa and said hey uh she's always had gut problems I would have sent you to someone who who does that like again I'm not saying that who though like nobody seems to know like when I say we finally even I couldn't resolve it for her as much as I was learning and meeting with experts like she finally just had to be like when I eat this what do I feel when I eat this what do I feel yeah I mean again this is not my area of expertise so I wouldn't act like it was um you know you'd be like I don't know yeah I'm really happy telling people I don't know there's a there's there's more things I don't know than I do know yeah that is uh that's something that a lot of people struggle with I definitely fall into the other camp where I feel like I know just enough to be like do this come back report so it was really interesting reading your book seeing how much of the things that I felt like uh in fact I'll say this another way I am I'm I'm I have a weird emotional hangup like I really want to I wanted to say the sentence that I'm going to stop doing intermittent fasting and and start doing what you're talking about and I probably should uh do I have orthorexia this is a very interesting question I feel it's so easy for me to maintain my body composition through intermittent fasting it's very easy for me to maintain my uh my satiety through intermittent fasting it's when I click over into kosis I find that my relationship to hunger is different but you did say that that if I'm doing it for body composition reasons fair enough that's very interesting so one thing that I know I'm just thinking out loud here one thing that I um I do often wonder about with my own physique is protein intake and muscle hardness when you like when I'm being really consistent with working out and I take my carbs up my muscles get really hard will I have a similar effect by and you know why that is right uh the glycogen is being push the muses it's more water right so more carbs means more glycogen every molecule of glycogen is bringing three molecules of water so you're you're filling up the muscle okay so then is there none of that relevance with protein because I was going to say like it's different right so so protein is contributing to the sarir the functional unit of the muscle the the that's that's that's the part that's Contracting right that's the functional piece of the muscle so that's what's increasing the synthesis of the muscle and that obviously contributes to size uh but it contributes just as much to function um but creatine you know will add size to muscle through water retention carbohydrates will add glycogen and water to muscle these things are important for performance also by the way so they're not just an aesthetic thing so carbohydrates uh creatine water protein synthesis all of this matters to muscle if I were eating more protein would you expect uh my muscles to feel more firm what uh am I going to be able to increase my strength more like it assuming that I hold my workouts the same cuz I'm trying I'm trying to think through do I change my diet or do I just keep doing what I'm doing now what I'm doing now is easy but I always thought I was getting I don't know how you're working out so I don't know right now what you're limited by are you limited by amino acids or are you limited by Progressive overload or are you limited by some other Factor so meaning I'm not overloading the muscle enough yeah are you over are you putting enough stress on the muscle or not do you have a high enough testosterone or not do you have enough amino acid or not any of those things can be the bottleneck um and you're are you're at the limit of your genes right like all of these things start to matter now my guess is virtually nobody is at the limit of their genes except for bodybuilders so I'm not at the limit of my genes what am I at the limit of right now probably and I'm not at the limit of protein anymore I'm probably at the limit of how hard I'm willing to train how much I'm willing to train and I'm actually I'm probably at the limit of testosterone as well because my tea is pretty low so I can't answer the question for you what is more protein going to do because I would need a lot more information to understand like how you're train what's your training volume what's your training intensity and you know all those factors okay so one thing while I have you that I I will say is my limitation when I think about what holds my physique back I get injured a lot and I get injured in a very specific repeatable way which I think has to do with stability which you cover in the book so um I have a very weak middle back and I compensate for everything by shrugging my traps so it almost doesn't matter what I'm doing I brushing my teeth I will suddenly realize Jesus and I have to like remind myself to I think it's uh retract my scapular like I I'm pulling that sort of midback girdle down um in the book you go into how you can rewire the way that your brain has learned to to control your musculature what what is that process I have injured my trap you're going to think I'm exaggerating I've injured my trap 115 times over the 20 years you say injured your trap say say more sent it into spasm so where I can't turn my head or I can't tilt my head uh literally last night in bed I was rolling over so just adjusting my posture and it went and I was like you've got to be [ __ ] kidding and so then I couldn't fall back asleep because I could just feel it tightening and tightening and tightening and tightening um that is the thing that has has held me back for forever it's the first injury I ever received the the first day in the gym doing an overhead press it went and I thought I was dying at that point I was like what the [ __ ] uh yeah I've injured it probably at least 115 times again it would be impossible for me to kind of give you the diagnostic here but I think I think if you think about the way I kind of go through that stability chapter um it start it starts with respiration so the first thing we'd have to understand is what's your respiratory strategy um so are you over over inflated underinflated chest breathing only abdomen breathing only all of these things um are you chest out are you hunched over like you'd want to go through how do you correct your your respiration strategy um and then you'd want to look at do you have for example segmental control of your spine most people do not I can't imagine yeah so until you have segmental control of the spine you are always going to disproportionately put Force at various hinge points in the spine do you have thoracic mobility of your spine sounds like you don't have thoracic Mobility the spine do you have SC what is thoracic Mobility so are you able to rotate through the thoracic spine so you have a cervical spine thoracic spine is the longest segment and then the lumbar spine um so most people don't have segmental people that like twist themselves on a chair that kind of thing like how would you do that yeah but if you do twist where are you twisting through where is the torsion what part of the spine for me almost certainly lower back exactly that would be the most common so most people are excessively applying torsion in the lumbar spine and you want to be able to dissipate it through the whole spine also when you talk about the flexion extension of the spine and by the way we made a bunch of videos like because you can't explain all this stuff in words so in the book there's a link to like videos where I go through what these things look like um but you know being able to do a segmental cat Cow exercise is a really good way to see if you have segmental control of extension and flexion of the spine from head to tail um so you know then we get into sort of do you have scapular control through the full range of motion through all four phases so protraction retraction elevation depression again very few people can can control their scapula through those things so stability and movement are uh you know intertwined very intimately and if you you know if you're trying to unpack these injuries you generally have to go back to the breath training how to train yourself how to breathe properly training yourself how to move properly and there are two schools of thought that I have relied on very heavily in my journey here and that of my patients and that one is called Dynamic neuromuscular stabilization DNS the other is called postural restoration Institute PRI bringing everything that I've learned from this conversation and the book today tell me if this makes sense so I I would like to add more MUSC muscle to my frame do do you know how much muscle mass you have right now I don't have you had a dexa scan I haven't man I'm really like I love that stuff but because no one's coming to my house to do it uh I haven't gotten tested it'd be very interesting you can't do it at your house you kind of have to go to the machine I'm I'm willing to do it I would be very keen to figure that out one I want to see if I have any well you should get a Baseline and you should you know you should figure out like where you are where do you stack up right now in terms of muscle mass if for no other reason then you can evaluate your progress if you let's say you you know you test your almi it's at the 70th percentile that's great but do you want it to be at the 80th percentile well this way you can figure out if the changes you're making are going to move you in the right direction or not all right so making my goal maybe even more broad is something you talk about in the book which is the centenarian decathalon uh so what are the things you want to be able to do when you're older you better be scoring very high on them depending on what part of your age you're in now because it's all going to decline as you get older so here are the things I feel like I should be implementing based on I am 47 okay and so what do you want to be able to do 40 to 50 years from now I want to be able to be very independent from a Mobility perspective so I love the idea of being able to um when I'm flying to Mars to be able to hold I guess before we Blast Off be able to put luggage above my head M uh uh so yeah I want to be able to to travel put things above my head I don't want to lose a lot of my strength I want to make and if you want to go to Mars by the way you're going to have to tolerate pretty high G forces so think about the next strength that's going to be required to do that yes also I would just like to not have constant trap injuries that would be amazing y um I want to be able to play video games okay tell me I don't play video games I do drive a simulator though so that's probably similar uh I would guess not from the perspective of what I struggle with so I had so much wrist inflammation for so long I think a lot about inflammation inflammation keep that down so you thank you by the way your uh encouraging me to add fat to my diet allowed me to go from basically never being able to play video games do I can now play as much as I want on Saturday which I mean I sure I could play more than that but that's just from a Time allocation standpoint so uh that's been a huge win so being able to do that uh sex huge thing in my life so being able to whatever that takes uh so a certain amount of flexibility I imagine uh stamina etc etc um yeah Aesthetics I want to look good I want to be strong look strong um something cognitive like being super sharp that would be really important well I mean if you're playing video games presumably you've got to have pretty decent cognition right you got to have um certain skills and um depending on if you want to be doing this yeah also true I don't need to pick up grandchildren that would be the maybe one deviation from what a lot of people want to be able to do but being able to be physically active I mean take sex is my like I want to be able to do that to the fullest um so given all of those things here is sort of how I see this now breaking out um sleep which we didn't really get into but I obviously I'm going to need to get sleep that's going to be super important um I'm going to need to identify given my family history I think it's either going to be cancer or heart disease neither sort of overwhelmingly prevalent um but those would be the two where grandparents died of that so certainly want to be thoughtful about that so I'd identified those two Horsemen so I'm going to be really thoughtful around my diet making sure that I don't have fat spilling out uh that I'm really thoughtful about the um APO little a [ __ ] APO B APO that's the one that gets into my cell walls arterial walls yeah and you do need to check your LP little a which is the thing we talked about as well that is genetic and occurs in about 8% to 12% of people okay so uh paying attention to my diet uh the adjustment that I'm thinking about making my diet I'm going to test not doing intermittent fasting see what that does for my muscle mass um eating more protein I have a feeling I might be lower in protein though I haven't counted up the eggs I eat a lot of eggs um and then I'm really curious to see about cycling Romy so what is your cycon rap ayon um I just dose it once a week just take one dose once a week yep okay very interesting um trying that what other changes I feel like that's you're going to have to have a doctor help you with that that's that's not an that's not an overthe counter yeah yeah for sure for sure I obviously would be doing this on the back of a lot of blood testing to make sure that I um am a that I know what my Baseline is B that I'm actually getting the result that I wanted um so yeah looking at the number on the um the cholesterol that we were talking about earlier grip strength is going to be one again not you know not sitting around with a little one of those like little grip squeezers because that's not really what it's about it's how do you develop grip strength you develop it by carrying heavy things right so you know this morning I was deadlifting and because I was doing it in the hotel and I didn't have chalk I was failing in grip today like it's actually funny my hands and my forearms are still sore 5 hours later because I was really at the limits of what I could do without chalk and you know I didn't have anything else so so but so yeah I was deadlifting but think about how much I was doing for my upper body even though that's a lower body activity um you know doing farmer carries something I love doing I mean I'm always trying to figure out a way to use my upper body to maximize the relationship between grip and shoulder so think of it less as like very specific tests that you do um and think of it more as the the broader activity you need to do to produce that so grip strength is just an integral of upper body strength all right so if if that is my sort of fumbly way through the things the changes that I'm going to make um if somebody wants to outlive and they come to you that cocktail party and you just cannot get away from them and you have to answer the question in a succinct way um what do people need to do to maximize the human life expectancy there is no sentence I can give any person to tell them what the prescription is right I mean if I could I wouldn't have written a 500 page book there's no chance believe me I didn't want to write a I wasn't look I wasn't looking for things to do right the reason this is complicated is that it's complicated um and two people can have two very different prescriptions you know if I'm at that cocktail party and the person I'm talking to after a few minutes I figure out that their biggest issue is that they're not sleeping you know or that you know they're sleeping four hours a night nothing else I'm not going to really waste time talking about protein with them we've got to figure out why they're not sleeping s to n hours a night and how much of that is sleep hygiene how much of that is underlying pathology like sleep apnea or restless leg syndrome how much of that is alcohol how much of that like you have to you have to get to the root of that problem but if you're sleeping 4 hours a night that's the elephant in the room if you're not exercising at all and you're sleeping well and you're sort of eating okay like none of that other stuff matters you need to get exercising if you have type 2 diabetes and metabolic syndrome you know I we have to get you exercising and changing your diet and all those other things so so again it it I'm not being difficult because I don't want to give glib answers I I'm not giving a glib answer because there isn't one if you want to learn how waking up at 3:30 a.m. can completely change your life be sure to click here check it out your life will change forever the moment that you decide to get up early and really attack your day go to bed at the same time every day
