Dr. Anthony Chaffee explains why fat and cholesterol are essential nutrients that modern medicine incorrectly demonizes, particularly for brain development and function. He reveals that 60-70% of the brain is made of fat, with two-thirds optimally running on ketones from fat oxidation rather than glucose. Babies naturally exist in ketosis both in the womb and while breastfeeding, making breast milk - the highest concentration of saturated fat and cholesterol in nature - the ideal food for proper brain development.
The episode explores how animals in nature, from lions to koalas, intuitively regulate their food intake without calculations when eating their biologically appropriate diet. Dr. Anthony Chaffee demonstrates this principle by showing how carnivorous animals naturally stop eating when satiated, maintaining lean, muscular physiques even in sedentary zoo environments, proving that diet - not exercise - is the primary factor in body composition and health.
Key Takeaways
Two-thirds of your brain optimally runs on ketones from fat, not glucose, making dietary fat essential for cognitive function and brain structure development
Babies require ketosis for proper brain development - they're naturally in ketosis in the womb and while breastfeeding on high-fat breast milk
Animals eating their natural diet automatically regulate food intake without measuring portions, staying lean and muscular even with minimal activity
Ground beef costs less per pound than spinach while providing complete nutrition, eliminating food waste and the need for multiple supplementary foods

And you want the fat. The fat's actually an essential nutrient. It's not just a calorie source. They're essential fatty acids that you have to have or you can get sick and die. They're essential fat soluble vitamins that you have to have or you can get sick and die. Your brain is made out of fat. 60 70% of your brain is made out of fat and a large portion made out of cholesterol as well. Cholesterol is really important. So important that your brain makes cholesterol. And there are countless studies talking about how if you disrupt your brain's metabolism for cholesterol, you get very serious neurocognitive uh disabilities and and problems. And yet we're doing everything we can to disrupt our normal cholesterol modulation and metabolism. Taking medications that will cross into the uh brain and and suppress your brain's ability to make cholesterol. Uh changing our diet so we we have less cholesterol. These sorts of things. And we're doing this with children too, which is I think is honestly a crime against humanity because uh 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 a fuel uh based on fat and they cross freely into the into the brain. They cross the bloodb brain barrier and they can re and they are act as fuel and twothirds of your brain optimally run on ketones. So if you have enough ketones and you have enough glucose, twothirds 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 cortexes which we do our thinking with is is uh optimally fueled on uh 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 their 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 uh and the ketones 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. They have sort of different fats. They say, "Well, you have to have omega sixes." So, you know, you need u u seed oils like vegetable oils and things like that. Well, vegetable oils do have omega sixs, but they have the wrong omega sixes. We don't need omega6s. We need arachidonic acid, which is an omega6. 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 that half of them are going to go bad and spoil before the other ones get used. And so, you end up 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 they 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 healthfully. And so, you know, I don't have any waste. I have actually saved a lot of money. I'm not buying coffees and snacks and thises and that or whatever. I I eat, you know, 2 lbs 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 a koala 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 instincts. 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 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 perfectly 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 to test that out cuz my dogs be pounding the food I give them. Yeah. Well, maybe they need a bit more, but they might. But but there is a point that they'll stop and because they they they know, you know, look in the wild again. Yeah. 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 them, but they they stop naturally. Koalas, they live in a tree. They have 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 them to stop. Hey everyone, really happy to announce a new sponsor for the show and for everybody down in Australia, Stockman Steaks, who are delivering highquality grass-fed and finished pasture-raised beef and other meats flash frozen and vacuum sealed to your 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 highfat keto mints and carnivore beef and organs mints with liver, kidneys, and beef heart as well. So, use code chaffy today for a free order of beef mints or another specialty gift along with your order at stockmanstakess.com.au and I'll see you over there. Thanks, guys. 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 um is nearly completely fat fat around the kidneys. Um the misenter which is the blood supply to the to the intestines completely covered in fat. 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. Lions 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 lion goes for the fat, goes for the abdomen, eats as much as he wants. No other animal gets to touch that thing until king lion'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 Lion is just doing his thing and then all of a sudden it's just he's done. He could and then the rest of him come in and 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 he doesn't, you know, and and they don't get fat, you know, he 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 lions aren't all that active. And you know, and uh but also it doesn't explain animals in the zoo, right? And that's what most people say is that, well, animals in the wild, they're always running around. Qualas don't run around anywhere. They're basically sitting there. A lot of animals are just very sedentary unless they have to be um uh 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 a 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
