The Carnivore Diet's AMAZING Impact On Your Health ( You're Underestimating It! )

Dr. Anthony Chaffee explores the critical role of ketosis and fat metabolism in human development and optimal health. He explains how ketones from fat oxidation cross the blood-brain barrier to fuel two-thirds of the brain optimally, making fat and cholesterol essential for proper brain and nervous system development. Babies naturally exist in ketosis both in the womb and while breastfeeding, as breast milk contains the highest concentration of saturated fat and cholesterol of any food in nature.

The discussion traces human evolution from our apex predator ancestors who thrived on carnivorous diets for at least 2 million years. Dr. Anthony Chaffee presents compelling anthropological evidence showing that pre-agricultural humans were significantly taller and healthier, with the Agricultural Revolution 10,000 years ago marking a dramatic decline in human height (5 inches average decrease) and brain capacity (11-17% reduction). He references studies of traditional populations like the Maasai and Plains Indians, who maintained superior health and stature through carnivorous diets, and discusses Dr. Pottinger's multi-generational cat studies demonstrating the profound nutritional differences between raw and cooked meat consumption.

Key Takeaways

  • Babies require ketosis for optimal brain development - they naturally exist in ketosis in the womb and while breastfeeding, but high-sugar baby foods and formulas suppress this critical metabolic state
  • Two-thirds of the human brain optimally runs on ketones from fat oxidation, which cross the blood-brain barrier more effectively than glucose and can reconstitute into fatty acids for brain structure
  • The Agricultural Revolution 10,000 years ago caused immediate health declines: average human height dropped 5 inches, adult male brain capacity reduced 11%, and female brain capacity decreased 17%
  • Plains Indians in the late 1800s were the tallest humans on Earth (averaging 5'10" for Cheyenne males) while subsisting primarily on buffalo and bison, compared to 5'3"-5'4" Europeans of the time
  • Dr. Pottinger's cat studies showed that cooking meat destroys essential nutrients like taurine - raw meat cats remained healthy across generations while cooked meat cats became sterile and developmentally stunted within three generations
  • Traditional populations like the Maasai showed superior health markers when consuming milk, blood, and meat diets, but developed chronic diseases after introducing modern processed foods and grains

[Music] you have to have fat and cholesterol high amounts of fat and cholesterol in your diet you have you need to be in ketosis to properly develop your brain and nervous system because ketones cross the bloodb brain barrier ketones are are from fat oxidization they they're just basically a fuel uh based on fat and they cross freely into the into the brain they cross the blood brain barrier and and they can re and they are act as fuel and 2third of your brain optimally run on ketones so if you have enough ketones and you have enough glucose two-thirds of your brain will only run on those ketones so it's actually a preference it's only when you start getting less ketones or not enough ketones that you start filling in the gaps with glucose and so some will still run on glucose but but the majority including the cortex is what we do our thinking with is is uh optimally fueled on ketones but the ketones also can reconstitute into uh fatty acids and make up the physical structures of your brain so when a when a baby's brain is growing and a child's brain is growing it's really important for them to get uh ketones a lot of ketones a lot of fat so a baby in the womb is in ketosis wow even though they're carbohydrates in breast milk when a baby is breastfeeding they're in ketosis because it's it's a lot easier for them to be in ketosis because they need to be in ketosis for their their brain and then we get them onto really high sugar baby food and formula and actually suppresses the ketones and and the ketos and you're not giving the proper fat dang so you're not a fan of baby formula no no no a lot of parents use that right they do and sometimes there circumstances require that they do um and that's unfortunate because they they don't have the same they don't have the same makeup as as as breast milk and they have sort of different fats they say well you have to have omega sixes so you know you need uh uh seed oils like vegetable oils and things like that well veg oils do have omega-6s but they have the wrong Omega 6es we don't need Omega 6es we need arachadonic acid which is an omega-6 we don't need random Omega-3s we need specific Omega-3s DHA EPA for our brain 20% of your brain is DHA massive proportion of your brain is and your body is made out of fat and so breast milk is actually the highest concentration of saturated fat and cholesterol of any food in nature and and so why are we scared of this why are we saying that this is bad for us and first of all that's that's been completely discredited that whole cholesterol heart hypothesis but you know just looking at at what kids need to eat they need fat and cholesterol um getting back to your point about about cost it actually ends up being cheaper so a pound of spinach costs way more than a pound of ground beef certainly and it can cost more than than many steaks do per pound and you're not going to get all the nutrition you need from spinach you will get all the nutrition you need from steak when with that spinach you're going to need to buy 30 other things there half of them are going to go bad and spoiled before the other ones get used and so and having a lot of waste uh meat i' I've really never had to throw out meat the worst case scenario give it to my dogs you know and so and yeah they're they're on a raw meat diet as well they're healthy as hell I just switched my dogs over to that and their skin is way better already and they look healthier yeah yeah and they will be they absolutely will be and they'll live longer too and much more health healthfully and so you know I don't have any waste I I've actually saved a lot of money I'm not buying coffees and snacks and this is and that's or whatever I I eat you know 2 pounds of meat and I'm good for 24 hours it's really convenient too you know for for people with a busy schedule because I'm just not hungry you know I I eat a big meal I eat until it stop I eat fatty meat until it stops tasting good I can listen to my body signals I don't have to figure out with a calculator how much to eat like you know if you're never going to see a W I pull out a calculator to figure out what to eat right and so if you need a calculator to figure out your Macros you're probably eating the wrong thing I was never a fan of that Trend there's apps that do it now you got to input everything you eat yeah that's it like where is that in nature nature is natural it has to happen just on its own and so if we have to figure out something and calculate it it means we're probably eating the wrong thing because we should be able to eat intuitively we should just be able to just eat our natural biologically appropriate diet and listen to our natural in inss we're not we're not here from space we're animals just like every other animal on this Earth we came from this planet and those same biological laws apply no animal in the wild can you you don't see like a fat Badger waddling around oh that one just doesn't have any self-control they know what to eat they know how much to eat and they know when to stop and we do too if we're eating the right thing and that's and that's a testimony to it being the right thing if you're just eating fatty meat and you eat until it stops tasting good your body will per L regulate what's coming in and out and so you don't need to worry about it and that I think that is a big testimony to understand that this actually is our biologically appropriate way of eating right yeah that's a good point because you'll never see fat animals in the wild but you'll see fat dogs fat cats fat humans yeah and but only when eating inappropriate diets you know like dogs that are just eating meat I mean you put as much meat as you want in your dog's dish it will eat a certain amount and it will stop really you think they'll stop oh yeah they will wow I want test that out my dogs be pounding the food I give them yeah well maybe they need a bit more but but but there is a point that they'll stop and because they they they know you know look in the wild again you I mean you have you have animals out on on pasture right you have cows that just live on their own food and uh and yet they stop sometimes you know they they they monitor how much they're eating um or actually they don't have to monitor but they they stop naturally koalas they live in a tree they have no no natural Predators they're just sitting there lazy as a lump and they're just sitting there just eating leaves and then they stop right they could just keep going but something in them tells him to stop uh Lions you look at a pride of lions and King Lion the alpha gets to when they make a kill Alpha gets to eat as much as he wants of what he wants and typically goes for the belly that's where more fat is that's like bacon is the belly uh belly meat and and there's a lot of fat around the organs the momentum is nearly completely fat it's fat around the kidneys um the meent which is the blood supply to the to the intestines completely covered in fast there's a lot of fat in the abdomen and I think that's why they're going for the for the abdomen as opposed to oh they're getting all the organs organs are great there's a lot of nutrients in them but I they're going for the fat I believe because they leave like the hunches the hind quarters they're very very lean lines will often leave those and eat the fattier parts of the animal first unless they're you know very hungry and then the hyenas will come in they'll eat the hind quarters and they'll be their jaws are strong enough to crack open the bones and get the marrow which is more fat and so animals always go for the fat so King Lon goes for the fat goes for the abdomen eats as much as he wants no other animal gets to touch that thing until King L's done right and so they're all just waiting I've seen videos of these where they're just like impatiently waiting like oh my God I want to get in there and uh you know Daddy L is just doing his thing and then all of a sudden it's just he's done he could and then the rest of them come in and devour the thing but he could just keep going until he just made himself sick and was just rolling on the back oh my God you know yeah exactly but it doesn't you know and and they don't get fat you know it doesn't doesn't get overweight they're ripped they're like on steroids and people say Well they're they're in the wild they're really active I mean everyone knows that male lines aren't all that active and you know and uh but also it doesn't explain animals in the zoo right that's what most people say is that well animals in the wild they're always running around quas don't run around any anywhere they're basically sitting there a lot of animals are just very sedentary unless they have to be um active and uh but again it doesn't explain animals in the zoo that live in a box the size of this room it's the definition of a sedentary lifestyle they just sit in in an enclosed area and don't go anywhere and yet when fed their natural diet they also look very strong very muscular very lean right and um and so so that's the thing if they fed them grains and inappropriate food they would get fat but they're not so being fed the appropriate diet and even though they're getting no activity no exercise to speak of they're extremely muscular and lean and healthy and so I think that's that's because of the diet yeah yeah I don't see too many healthy vegans the only one I've seen actually is Brian Johnson yeah well he takes 160 different supplements and he has a whole team you know spending about $3 million a year keeping him that way the interesting about Brian John interesting thing about Brian Johnson is he said that um well and he may haveed Chang his opinion on this but I I did hear him say at one point that he didn't wasn't doing the vegan diet because he thought it was the healthiest diet that was just his choice that's how he wanted to do it and so he had his team figure it out and so it's like okay I want to do a vegan diet I want to do it this way you know you figure out how that works and so that's why he's taking 160 different supplements a day because you have to you know there are essential nutrients that you cannot get from the entire plant kingdom from the entire fungus Kingdom they just don't exist B12 is the classic example but there are more I mean you look at um and and that's the argument to you cannot say that that humans are herbivores for a lot of reasons but it just starts and stops at B12 there's no B12 in the plant kingdom right right you have to get that from meat and so we couldn't be herbivores we couldn't have evolved as herbivores and we didn't evolve as herbivores I mean that's absurd all the best evidence shows that humans have been apex predators top of the food chain which by definition means carnivore for at least 2 million years if not longer 2 million Homo habilis with the with the onset of the ice ages 2 2 and a half million years ago there was this inflection point in um early human and then human evolution where people you know 8 million years ago or so um we split off from our ancestors who are largely herbivorous and because they started eating meat they started eating more and more meat more and more meat they started having more uh genetic adaptations to closer to what we are today started getting taller starting getting bigger brains because we had to figure out how to get meat we were just naturally predisposed to hunting like a lion taking things down we had to scavenge we had to figure out how we could take a rock and smash open the skull of a dead animal and eat the brains and things like that and then get sharpened tools about 3.3 million years ago we got uh the first example of a sharpened tool that we can now use to cleave and cut off meat off the bone and we see butcher marks very classic clear signs of Butchery on on you know bones around that time and Beyond showing that this was intentional butchering and carving and ripping off meat with these stone tools that were again found in that area and you can see the the you know the deposits in those cut marks in the bones that came from that Flint uh ax over there and um so we have very good information about this so our brains were growing our Jaws were getting smaller teeth were getting smaller because we're chewing on we're eating softer and softer Foods we're not chewing on sticks all day like a gorilla right and so we had these adaptations then about two two and a half million years ago the ice ages started we didn't actually have polar ice caps two and a half million years ago or so when the ice ages started we're in an ice age we're sort of in a in an e of an Ice Age um when the that ice shelf started coming down obviously ice kills things and it stops you know kills animals and plants and things like that they were surviving in the area and and animals had to had to specially adapt or die out and our ancestors in Homo habilis did and the adaptation that they had was they were able to turn to full carnivore apex predators so they didn't they weren't just Scavenging now and then getting a kill even now and then now they were able they had the technology and the brain power and the tactics to be able to take down large animals and um and get the whole animal you can get the organs you can get the meat you get all the fat you weren't just getting the scraps right and there's an inflection point in our in our Evolution at that point so our height and brain size was coming up steadily over you know millions of years since our ancestors started meat then about 2 and a half million years ago bam it's just an exponential increase in brain capacity and cranial capacity and height up until about 15,000 years ago it's going up and up and up and up and up and bang straight down straight down and um anthropologists and P anthropologists show that in the fossil record there's a clear point right at the point of uh the Agricultural Revolution and this is isn't just in you know all over the world happened this happened when a society went from pre- agriculture to post- agriculture at starting about 10,000 years ago but at other points in time people have come across agriculture been introduced to Agriculture and you see the exact same thing and as um oh I'm going to butcher his name but it's Professor Ula jic uh from Oxford I can get it spelled for you if you like but um I'm good on that yeah but um but uh he said that um you know about starting about 10,000 years ago um you saw this clear distinct line in pre- and post agriculture that the height the same thing occurred regardless of the time regardless of location and regardless of the type of crop that they moved to the same things happened the height health and um height and health of the population declined and and they said there's all these signs of malnutrition infectious disease and all these other things that that came on afterwards the Jaws got smaller started getting crooked teeth Fallen Dental AR Weston a price was a dentist 100 years ago he showed this in these these native populations Perfect Teeth perfect Dental arches until they started eating Western food and didn't get enough fatty meat and specifically he was he found that it was the fat soluble vitamins that you needed to to develop your your hard pallet and your dental AR arches and and jaw and um in the same families all of a sudden you know Johnny starts eating this other stupid food that come in in you know from the from the towns and has screwed up teeth wow and then they can reverse that by giving them fatty meat and uh whole milk and things like that and and then the next Generations they could they could get the get the teeth back things like that but we saw that you can tell the difference between a a pre-agricultural and post-agricultural skeleton and teeth especially because of that dang and and the brains went down so after agriculture the adult male brain Capac capacity reduced by 11% female adult brain capacity went down by 177% and the average height went down by about 5 Ines holy crap and so that wasn't over hundreds of years or thousands of years that wasn't an adaptation process that was overnight in the fossil record so that happened immediately and and that's persisted until today and we saw this in real time again with the Native Americans the native Canadians um the uh native Australians and we're seeing the Messiah as well who are traditionally carnivores they have a large portion of that carnivore diet being milk but milk blood and meat is their is their staple diet and they started introducing some plants throughout the 20th century and they started getting some of these human diseases throughout the 20th century as well now they have Coca-Cola trucks going to the mimura and these little Villages and they sell out very quickly because they don't know how harmful this stuff is and now their diabetes is actually going up and their tooth decay is going up and their chronic diseases are going up even though traditionally they're extremely healthy so now they're seeing that inflection point that anthropologists talk about that they go from the this just injuries and infectious disease and actually pretty low infectious disease rate uh there's a study out of the out of um the British that in the 1920s and early 30s they actually have they're actually extremely healthy have very low rates of um like almost no chronic disease and very low infectious disease rates as well and they were much taller stronger healthier had more lean body mass than their neighbors the akiyu who they inbred for who knows how many hundreds of years or thousands of years so they're genetically similar population and the akuu were largely vegetarian and they so they were just growing their own crops this is out in the middle of Africa they're not in cities they don't have pollution they don't have um you know commercial Agriculture and and uh you know pesticides and fertilizers just it's just living out on a commune you know growing grains and things like that they were much less healthy the MSI were 5 in taller on average 23 lbs heavier of lean body mass stick skinny just really really spelt people and um 50% stronger and they didn't have any of these chronic disease issues that the akuu had who also had a lot of nutritional deficiencies the British started supplementing them uh with the different nutrition nutrients that they were lacking and it didn't actually make them healthier it wasn't until they replaced the plants they were eating with meat that they got healthier hey everyone really happy to announce a new sponsor for the show for everybody down in Australia Stockman Stakes who are delivering highquality grassfed and finished pasture raised beef and other meats flash frozen and vacuum sealed tood door something that I've been enjoying a lot of myself recently as well they also have a great range of specialty items such as high fat keto mints and carnivore beef and organs mints with liver kidneys and beefart as well so use code chaffy today for free order of beef mints or another specialty gift along with your order at Stockman stakes. comom and I'll see you over there thanks guys there's no mention of heart disease anywhere in that study with the with the Messiah in the 1920s and yet in the 1970s you start seeing oh yeah well there's a bit of it there but I know people that have volunteered in Africa in the in the 80s and they were like yeah that was never anything we treated we never treated these chronic diseases it was always different different things now you're seeing it now you're seeing it show up more now you're seeing diabetes which if you have diabetes increases your risk of developing cardiovascular disease by a thousand per. right and metabolic syndrome will increase it by 600% and so those those are major major risk factors that those metabolic issues are major risk factors for all these chronic diseases and now we're starting to see those in the Messiah and we saw those you know and those disparities between the Messiah and the akiyu exactly the same disparities that we saw pre and poost agriculture in the fossil record and the Native Americans like especially in the Great Plains there was a study in 2001 that was just called tallest in the world and they looked at records from the late 1800s with the the Plaines Indians in the Great Plains they were largely just eating buffalo and bison and then they found that they were the tallest human beings alive on Earth at the time they were far taller than the Europeans you know 5 six Ines or more taller on average um and there's there's sort of an average between them somewhere you know ranging from like 5'6 to 5' 10 on average but the Cheyenne were about 5' 10 on average adult male height and now in America last I checked it was 5'8 so it's still taller than people here today but um but they were far taller than people at the time which much lower more like 53 5'4 and so they were much much much taller and that was at the end of the 1800s after they kill all the bison and put them on the reservations that's a really interesting thing so they were still taller than body else even though they had started transitioning onto a more Western diet and started getting sicker and started having that their height come down and in those original those studies and measurements they said that the older Generations were far taller than the younger generations and so if they just looked at the older Generations or maybe looked a 100 years back the average height would have been much much taller and in fact we see the fossil record of people going back tens of thousands of years who back before the mega fauna died out because we were eating um Mammoth um that the big Mammoth Hunters that some of these people were on average 6'2 to 6'4 average that's crazy right and so you know I would I'm 6'3 I would be average you'd probably be you know slightly above slide above that but you know everyone would be you know just it would just be you know a population of you know NBA players and things like that eating a mammoth damn eth so why do you think Asian people are so short well a lot of it's going to be because of diet as well you know you look at um the Mongols well you look at more recently um there there there's been a lot of famines in the 20th century as well with you know Ma and the forced famines and uh and poverty and things like that and of course if you're not getting adequate nutrition during development you're not going to grow as tall as you you possibly could and and we see that all over the place which is why I think it's it's a it's a crime against humanity to not to to be putting kids on vegetarian diets or processed food diets and formulas things like that not and vilifying me and say no no no it's bad putting 5-year-olds on statins are you out of your mind I mean but people are talking about that that that you should put kids on statins if they're if their cholesterol is high they need it needs to be high their brain needs it to be high their body needs it to be high and it's good for you all your hormones are made out of cholesterol or your steroid hormones are made out of cholesterol vitamin D is made out of cholesterol so if you're not giving kids adequate nutrition they're not going to develop properly and so you've had a lot of force famines and poverty uh throughout the last century in in China and elsewhere and and people are going to be shorter as a result of that then you see people I I've I've known many friends that were first generation American and they you know their parents are these these wizen little old Chinese people they're 6'4 just ripped yeah that happened to me my grandparents were super short there you go yeah so I think I think a lot of that's nutritional and I think that um there there's a stark contrast specifically because of of the malnutrition that you know was was prevalent in the 20th century for various reasons look at genas Khan the Mongol horor they were carnivores they ate you know horse meat they drank horse blood and fermented Mars milk very lactose intolerant it had to be fermented and still to this day persistently lactose intolerant some of the more lactose intolerant people in the world as a population and yet they have a lot of fermented dairy but um uh they can't they can't do the lactose and they obviously carved out the large contiguous Empire that's ever existed on Earth and you read histories about um genghiskhan and the Mongols and a large a large portion of that success was attributed to their diet they're extremely wellfed even the most base fighter in the Mongol EMP Mongol horde had had a lot of access to meat and high protein and nutritious food while they were fighting against these peasant armies that were just already subjugated they're just eating a bunch of GRL they had a lot of health issues and they were just weaker and more frail and just malnourished and they they actually attribute a lot of their success to how healthy the the Mongol people were because they were eating such good food wow it also was an advantage because they didn't have to cook three times a day so they didn't have to stop their armies and they didn't have all these cook fires going up as you can track an Army in the Horizon by the smoke that's coming up like okay see how fast that those smoke clouds are moving they're going to be here in 3 days okay we have 3 days to prepare you didn't have that with the Mongols they just showed up out of nowhere were eating raw meat they would eat raw meat they could they could cook it as well they would U you know people always saying about uh you know how uh you have to like there's a thing now in Australia where they're telling you know parents not to put lunch meat in their kids sandwiches because oh we we don't have refrigeration so it could be like 3 hours before go you just rot and go to hell like you out of your mind like like no one's ever brought a sandwich to school or work before it's like this is the first time this has ever happened uh the Mongols would take a raw piece of meat and put it under their saddle and ride on it for several days to to to tenderize it wow and then they'd eat it Savage and they could go 5 days without eating eat 10 pounds of horse meat and then ravage the countryside for another 5 days and and do it again and uh and they could drink blood as well the Messiah drink blood and they just sort of pop a little hole in a vein and drain some blood they drink that and it keeps you going it's amazing nutrition and it's and it's a renewable resource as well they're eating grass they turning it into blood drinking the blood you just keep going it's like it's like milking them and and you do it in a rotation so you're not over overdoing it but it works it works uh very well and and uh they were much taller and healthier and more robust as well and um so yeah so it's uh I think you'll find that in populations any population you go back to eating that way the kids will be taller and smarter and have bigger brains we saw this in cats there's a very famous doctor named Dr pottinger and and Dr Price I mentioned before there's a organization called the price pottinger uh Foundation carrying on his wor and pottinger is this other guy Dr pottinger Who randomly was uh my mom's doctor as a kid in California at one point and said you need to feed I mean my I don't remember the health issues she was having at the time basically said she needs to eat raw meat and like or raw liver and every day she had to have some raw liver every single day and they actually sorted out her her issues wow and um he did a he did um a study with cats for several years many years probably 14 or something years and um looking at nutrition because they're studying tuberculosis and he thought that tuberculosis had something to do with the adrenals in fact it has to do with diet pre- and post agriculture pre- agriculture you don't see any signs of tuberculosis infections post agriculture immediately you saw signs of tuberculosis in in in the spine of um of the fossils and things like that and then Dr J Salsbury who was a New York doctor in the 1800s did a 30-year research project into the optimal diet for human beings living with the Native Americans seeing they were just really healthy with you know just eating meat they were living to be 110 115 years old and they like oh well that's that's farfetched I like actually it's not because I was taught in genetics last 20 plus years ago that we are designed based on the length of our tiir and our chromosomes genetically we're designed to live 120 years on average so people actually just living to be 115 120 years old that's actually normal that should be what how long we live but we're dying in our 60s and 7s and 80s and calling that a good life because we're sickening ourselves for decades and eating these low-grade poison and not getting proper nutrition and our bodies are just failing 40 years early 50 years early sometimes um so he was looking at and and and Salsbury actually found that when you put people on just a pure red meat water this is long before processed food and garbage they cut out the grains and the and the vegetables and just eat red meat and water you could reverse autoimmunity like rumor arthritis and Crohn's reverse gout and even tuberculosis he was actually finding that he was getting people healing from tuberculosis which was a major killer back then um by putting them on a pure red water diet and so pottinger was looking at um the adrenals and so he was taking uh doing an adrenalectomy which they took out the adrenal glands from these cats and we're going to expose them to TB and and sort of see what happened but all the cats were dying hey guys just want to take a second to thank our sponsor at carnivore bar I don't promote many products because honestly all you need to be healthy is to just eat meat for those times that you're out hiking road tripping or stuck at work and you want nutritious snack that is just meat fat and salt if you want it the carnivore bar is a great option so I like this product not because it's just pure meat but also because I want the carnivore Market to thrive as well and the more we support meat only products the more meat only products there will be available in the mainstream so if this sounds like something you'd like to get behind check it out you using my discount code Anthony to get 10% off which also applies to subscriptions giving you 25% off total all right thanks guys and so I couldn't figure out what's going on people were sort of passing in Strays before they all spay neutered um animals back then so it was a lot of Strays so they're getting like a lot of cats more cats than they knew what to do with and um and they sort of had more than they they needed mostly they were cooking the meat and giving it to the cats they're still just giving him meat but they were cooking it and then they sort of just sort of for time management they're like all right well we have too many cats we we'll cook as much as we can but then we'll give just raw meat to the rest of them the raw meat ones all survived all the cooked meat ones died raw me ones lived and they're like okay well what the hell is going on is and they switched the focus of his research to okay what what nutrients are you are you losing something when you cook meat and found yes you do you lose torine you lose glutamine you lose other sorts of things and and torine is essential to cats um and so they have to have raw meat M and so they looked at it and they found that the the raw meat group uh there's a lot to this but I'll paraphrase and get to the high notes the raw meat group was extremely healthy generation after generation after generation big strong animals perfectly formed uh cheekbones big brains for a cat and uh you know proper bone density all that sort of stuff and the cooked meat cats the same meat is just cooked were much less healthy and the Next Generation they were smaller they weighed less they had like about half the bone density their brains were smaller their cheekbones weren't as developed and they weren't as interested in play they weren't as interested in mating the Next Generation they were even sicker even smaller less developed facial structures even smaller brain and their bones were so soft because they only had about 3% bone mineralization same amount of calcium the calcium doesn't cook out but because of how this changed the nutrients and how the body process these nutrients uh their bone mineralization was down around 3% wow and so their bones said were so soft and flexible it was like foam rubber and so they could have dozens of fractures and they were sterile at that point they couldn't have babies they weren't even interested in mating really but the ones who sort of did mate couldn't get pregnant or um the few that did get pregnant had still births wow so they couldn't make it past a third generation on cooked meat and then they switched them to raw meat and they got healthy again now they didn't grow after that because their growth placeat were already closed so it' be like your grandparents and you come to you know an area that had more access to food they are much more healthy but they're done growing at that point but their kids could could benefit from that and so the cats were able to reproduce and you think well the Next Generation they'll just be back in normal again no it took four generations to breed back to where the the raw meat cats were so there's this this multigenerational epigenetic KnockOn effect that that happens when you when you aren't as healthy as you could be so it's actually a big impact so you know you're going to be a lot taller than your parents and your grandparents and if you eat properly your kids are going to be even bigger taller smarter and stronger their kids are going to be even better as well and we're just going to get taller and taller and taller and better and better you know genetically I should be 6768 my grandfather on my father's side he and all his brothers were pushing s feet tall wow and my dad and his brothers are all from between 64 and 67 so something happened there yeah my me and my brothers 510 63 and 64 so just three generations we've just got a little bit shorter and a little bit shorter and a little bit shorter and so why the hell is that well you we had this big plant-based push throughout the 20th century when my dad was uh was a young man he they started pushing this whole cholesterol heart hypothesis you shouldn't eat fatty meat all that sort of stuff and um and so he you know took that very seriously and we just we ate meat but we trimmed off all the fat and we had you know like whole grains and all that sort and you know milk and skin milk and grain so we just EA that you know the the the you know fatty Pig diet you know to like fatten up pigs in the 1930s that that's what we grew up on D you know he was a he read Dr pin's book which was all about just eating um basically no meat but certainly no fat and how how important that was and and so that's that's how we grew up and my little brother really wasn't a fan of meat he mostly ate uh white rice with tempora sauce that was all you could get him to eat as a kid and um and he's 5'10 I'm 6'3 my brother is 6'4 and um you know in when I was 18 I was um I wrestled at 215 lb weight class my little brother was 148 weight class holy crap yeah big difference huge yeah and I always Lov meat I always want to eat a lot of meat I also didn't have braces neither did my brother or my sister my older one of my sisters who decided she wanted to go vegetarian as a teenager and my younger brother who basically just didn't eat enough and just ate a bunch of rice they were the only two people in my family that needed braces wow and now we know in the Dentistry journals that crooked teeth are not genetic it is is it is uh Developmental and mostly nutritional and also if you're chewing on soft foods you're not stimulating your heart pallet in your jaw to grow properly so you need to be chewing on you know you don't not sticks like a gorilla but something firm enough to to trigger that that growth response which is meat yeah and um and get the fat soluble nutrients that you need which are really important [Music]
