Kind: captions Language: en with this process happening with them just pulling in more and more fuel and growing in size are there foods that can actually restrict these fat cells from growing slash cut off their nutrient Supply so they won't continue to get as big yeah before we talk about fuels let me just sort of foods let me just say that actually our body has its own kind of like regulatory switch so here's the thing uh we talked about insulin uh that rises in the body as a response to eating basically food's coming in energy coming in your body senses it it makes this hormone um uh insulin and Insulin actually helps to draw that energy into regular cells as well as store stored into fat now here's something really important about normal healthy fat now I'm going to talk a little bit more about normal healthy because understanding the normal allows us to understand the abnormal if you just jump to kind of like the the demon all right then you miss the good guy part of it right this is this like a you know kind of like uh it's not black and white um there's a transition where fat is good until there's too much of it and then and then it actually becomes harmful and what we want to do is respect our fat and tame it not vilify it and not try to cut it out suck it out you know and poison it so normal fat I mentioned is an organ and that organ organ it's an endocrine organ it's actually like a thyroid like a pancreas like an adrenal gland and this is quite amazing to think about fat as an actual organ and it releases about 13 different hormones all right hormones are just proteins that are made released by an organ go into the bloodstream and they go elsewhere in the body to help to control different kinds of functions so one of the things that fat does as an organ it releases leptin leptin is sort of an appetite regulator turns up and turns down your appetite depending on the number about the volume so controls your behavior okay and the reason I'm mentioning this is that you know what when the leptin's high and it turns down your appetite you don't want to eat so much guess what less fuel less need to keep storing that stuff in number one number two it produces a super powerful hormone called adiponectin now many people may not know this term adipine nectin but if I were to draw your blood Sean take it to a lab ordinary Hospital lab and measure all the hormones in your body your adipic nectin levels and Mine by the way would be 1,000 times higher than any other hor uh hormone in your body higher than your thyroid higher than your testosterone higher than any other organ and the reason is adiponectin is what allows insulin to pull that energy in to your cells it's another hormone made by fat by good good healthy fat we need that fat to make to get our energy our Basic Energy all right now there's one more hormone I want to talk about it's called resistan made by fat and resistan basically is the break to the gas pedal of a dipon necton so if a dipon in at a thousand times higher than any other hormone in your body helps insulin pull fuel into your body into your cells resistant is the break to basically say oh whoa let's a little let's slow down a little bit normal balance right right so the life is all about balance ad dionin resistant leptin these are just three of the hormones in normal healthy fat here's the thing when you've got too much uh uh fuel that needs to be packed up and those fat cells get hundreds of times bigger and then they replicate and stem cells make more and more fat and they get bigger and they get hypoxic in the middle and they start dying because they can't get enough blood supply what happens that inflammation actually derails your normal Fat's ability to produce these organ these hormones leptin gets screwed up now you you don't know if you're hungry or not you can keep on eating it's worse okay now you can keep on loading more fuel your adipine nectin gets screwed up so now even though you're eating and you've got all this energy now your body can't pull it into the cells doesn't even store it very well and then the resistant goes Haywire so basically it doesn't know if that should slow it down or speed it up and so basically it's kind kind of like uh uh over um as as excess fat grows it's basically like creating chaos and air traffic control nobody knows where to land the planes and so this causes even more chaos so the important thing is how do we actually tame that excess fat and so the body can do some of it by itself like our our body is hardwired to know how to tame fat to some extent not if it goes too crazy but secondly and this is sort of like the surprise is that there are certain foods that can do it as well but the how your body does it is actually incredibly important because when we're not eating okay fasting when we're not eating like when we're sleeping all right insulin goes down and our body basically says oh when the insulin's down we can burn fuel when insulin's up can't burn the fuel can't tap into those fat uh cells fuel cells when insulin's down like when we're sleeping it goes all right not eating we need to pull into we need to draw into our fuel cells let's pull some energy out and it starts to actually burn extra fuel by burning extra fat so when we're sleeping our bod's hardwired as our metabolism is hardwired to start burning down extra Fuel and this is really kind of the basis of thinking about intermittent fasting uh timed eating uh you know the longer we give our body's natural metabolism or hard wirring to burn that fuel the better it is now it turns out that certain foods and this is the big surprise that I write about eat to be your diet certain foods can amplify that effect not just when you're sleeping but even when you're eating so it's an override you can actually use food to override that system so even though your body is not supposed to be burning that energy it goes let's just let's go ahead and burn some energy anyway it's fascinating fascinating one of the things that I love about your work and your book is that you're reframing food as well because a lot of times we see food as an enemy and you're saying food is not the enemy it's actually the solution you know um food is a big contributor to so many of our problems if we're talking about obesity if we're talking about excess fat gain and it's also the solution right and so choosing intelligent Foods because that's the thing these Foods it's not just food it's information and there's an intelligence underlying all of this stuff and how it's influencing our metabolism so at this point let's get into and circling back to my initial question when talking about the growth of our fat cells in angiogenesis the creation of those new blood vessels let's talk about first in this fat loss equation what are some foods that have anti-angiogenesis properties that can help to cut off that nutrient Supply to fat cells well this actually goes all the way back to my research in the uh late 1980s I was super interested in finding ways to fight cancer by cutting off the blood supply so I worked in a lab and we were we were looking at uh before Pharmaceuticals were developed biopharmaceuticals were developed for this area we were looking for natural sources and the and um and we're looking for anything in nature that could give us a clue uh of of how nature might provide a natural chemical that could cut off the blood supply to cancers now we knew actually even back then like licorice could do it St and licorice could actually cut off the blood supply to tumors feeding extra cells from that you don't want to be you're not talking about Twizzlers what's that you're not talking about Twizzlers are you we're not talking about Twizzlers so I'm not talking about Twizzlers I'm actually talking about Licorice and it turns out that there's a natural chemical found in licorice called ice ol liquitron all right now as a researcher one of the things that we're able to do is to know something's in a natural compound take it out and test it in the lab we tested isol liquitron on blood vessels that are growing to feed harmful cells like tumors like tumor blood vessels and it actually powerfully stopped those extra blood vessels but the thing that really brought it home for me and uh I've never forgotten this is a a research study that was done by a uh Greek researcher working in Switzerland uh his name was Ted FIS and he looked at the urine of uh villagers outside of Kyoto Japan these villagers were all vegetarians I ate mostly soy okay and and he had Frozen jars of this urine and his boss his supervisor said you know go find something interesting to do with the urine or toss it out so he went to look for hormones inside the urine thinking that he was a hormone he was an endocrinologist so he was interested in looking at hormones when he ran the urine underneath this thing called a mass spectrom tree okay you see these spikes and he found a spike that didn't belong in the human and it only came from the soybean and it was a spike of genin so he cut out that Spike which we can do in the lab and he tested it on blood vessels that would be feeding cancer and immediately stopped those blood vessels from growing and so this was the Discover that genesin found in plant-based foods like soybeans could actually be anti-androgenic and they could cut off the blood supply feeding cancers really was a mindblowing uh Discovery and I read this uh and and I know Ted FES um we had this conversation about it and it was absolutely amazing to think about what other Secrets might be in food that could help to control the blood vessels now now remember earlier we talked about the fact that growing fat needs extra blood vessels right so it's trying to grow those blood vessels if you deliberately cut off the blood vessels to that are feeding fat all right it'll actually shrink the T it'll shrink tumors and it also shrink fat so although the tumor wants to grow more blood vessels and it can't so it starts to die in the middle if you then step in and do an intervention to really cut off the blood vessels that fat mass will shrink and this has been shown very conclusively in the lab that this can actually happen green tea another the katans egcg powerful anti-androgenic uh can cut off the blood supply feeding tumors can cut off the blood supply feeding fat as well so one of the reasons I really came up to this whole idea of body fat is not only my background in this research thinking about well maybe fat growing the way that we talked about cloning itself getting bigger and bigger bigger your hypoxic in the middle that to me resembles a tumor exactly and so the question is could we tame the tumor by uh taming the blood supply and I've remembered the work that was done earlier and it turns out that many of the foods that I wrote about my first book that are anti-angiogenic my first book being e Tob disease more than 300 Foods there a whole chapter on anti-androgenic cancer starving Foods blood vessel taming flu Foods and I started to realize here was this whole opportunity to look at ways of taming our body fat as well and the epidemiological study supports it wow
