They were the tallest human beings alive on earth at the time. There's a study in 2001 called tallest in the world, and they looked at original source data where they were actually measuring a bunch of Native Americans on the Great Plains, and these guys were largely meat eaters. They were eating buffalo year-round. They were the tallest human beings alive on Earth at the time. The really interesting part of that study was says very clearly that the young men were the shortest in the entire tribe. The fathers were taller. Grandfathers were even taller. If we did the study 100 years ago, this would be way different, this average height would be well above 6 ft tall. And when the study was done, when those measurements were done, was after the bison were wiped out and they were put on reservations. So that was that transition period. You saw it in three generations.
Autoimmune diseases just melt away. Our body is reacting to different things that we're eating. We're causing an immune response and antibody response, and then some people who are genetically susceptible have a cross reaction to those antibodies with parts of their own tissue and it's damaging them. And we've actually . . . it's in the medical literature. We've been treating autoimmune diseases like rheumatoid arthritis, like Crohn's, like gout, or you know, gout, not autoimmune . . . but things like gout, and ulcerative colitis since the 1800s by putting people on a pure red meat and water diet. And this was known and books written about this going up until 1975 by Dr. Walter Voegtlin, 1904-1975, who wrote a book called The Stone Age Diet. He is a gastro-enterologist. And then 1977 came along, USDA said, you know, cholesterol causes heart disease, stop eating it and we just threw out 100 years of medical literature.
Every single day that you eat, if you eat something different, you will have a different microbiome at the end of the day, because bacteria turnover is 20 minutes. They rely on what we send down the pipe. If you eat different things, you'll have a different biome everyday. So whatever day you take that test, you'll have a different result. You eat something, you know, curry chicken, this day, and you send it in you're going to have a different result. You have a vegetarian meal on that day, you're going to have a different result. You're just eating steaks with no seasonings, you're going to have a different result. The microbiome that they've tested in carnivores and in different sorts of people that only eat meat or animal products is actually quite a good profile, very, very diverse. You have all these different sorts of . . . a lot of different bacteria. You're not supposed to have an overgrowth of a few. They seem to be the ones that are correlated with better health. Now, is this because the bacteria themselves play a role in contributing to our health, or is it that what we're eating has a direct has a direct effect on our health and that also has a direct effect on what bacteria are going to be living in our gut? I think he's probably is probably both.
The more saturated fat that people are eating the lower their stroke rate. The less saturated fat they're eating the higher the risk of stroke. And so this goes completely counter to the idea that fat is bad for us, and, in fact, there is a number of studies looking at LDL cholesterol finding the exact same thing. They found an inverse correlation, the Framingham study found an inverse correlation. That's one of the seminal pieces in Cardiology in the cholesterol theory of heart disease. And in fact, it found the exact opposite of what it was reported to have found, and there are number of other studies that support that as well. But if you just think down to . . . if you get down to brass tacks and first principles.
And we know that B12 deficiency even as an adult you can lose a percentage of your brain matter. The brain on the right is a 40 year old brain and you're losing 0.05% to 2% every year, you're damn right that's what your brain is going to look like at 80. Of course, it will. But with proper nutrition, it doesn't have to. And what I think is also striking here is that this one from an 80-year-old brain, huge improvement. But it doesn't look like a one-year-old brain. Why the hell not? Did they just lose out on their ability to develop normally? Maybe. But also they are replacing B12 lost via their vegetarian parents. What about the vitamin D? What about the choline, the creatine, the carnitine, the DHA, the EPA, the cholesterol, the saturated fat, I'll bet the LDL is pretty damn low. --Dr Anthony Chaffee
The average person is sick and malnourished.
80% of the calories consumed in America, Europe and the rest of the world really are from plants and plants don't contain B12, and so you have a vegetarian population basically. And you're checking their average B12, and you're saying, "O, everybody's in this average." Well, it's an average. Of course, they're in the average. But all those people are deficient because everyone is deficient, now no one is deficient because it's hidden in that average. But if you're below 650, 700, you can actually get demyelination. Oxford University published a paper in 2008, that showed that under 500 picomoles per liter, 600 picograms per milliliter, down to like 300 picomoles per milliliter, you know, 450 picograms and lower that people were getting so much demyelination of their white matter that their brains were shrinking by 2.5% to 5.5% every 5 years.
1:56. And that's my theory as well. Why do brains shrink? We accept that. We say our brains just shrink as we age even though no other animal on earth sees this. None. And so we just accept that our brains rot out of our brains. Okay but if we are losing half a percent 2% of our brain per year because we are in the normal reference range for B12, after 34 years your brain is going to be shriveled up. And you look at case reports. There's a case report in 1997 of a baby a 6-month-old baby who was a child of vegetarian parents who had severe atrophy to developed and so it was very very shriveled, atrophy. It looked exactly like an 80-year-old patient with Alzheimer's . . . dementia. Then with daily B12 replacement after 5 months, the brain swelled up significantly. It looked like basically a healthy 40 year old brain, but it didn't look like a one-year-old brain like it should have. And so you know it looks like an 80-year-old brain, a 6-month-old baby with severe B12 deficiency looks like an 80 year old brain. So why are we calling that 80-year-old brain normal? And then you give them B12 and all of a sudden it looks like a 40-year-old brain 5 months down the line. So I don't think that's age related atrophy. I think that's malnutrition over time. That is why I think people with MS are seeing a reduction in their lesions because they're just getting the basic nutrition that we need. And so working in neurosurgery, I have seen dramatic recoveries from a neurological perspective, more than I would have expected. Because normally we don't expect the brain and the nerves to heal all that well. It doesn't surprise me now, because we've been malnourished we don't have these nutrients like B12 that are allowing your brain to heal if your B12 is at a level that is so low that you are getting demyelination your nerves from MS. It's not going to happen; it's not going to happen. But then people do this and they're eating the fat, they're having some liver, they're getting the their B12 and vitamin D up and their DHEA and their and LDL and all that sort of, or DHA and EPA and LDL. They're getting all of those things up in proportion. Now the body can actually start healing which we don't think is possible as doctors and clinicians, because we just don't see it. And we think that the brain shrinking over time is normal because we just see it. It is the norm but it doesn't mean that it is normal. It doesn't mean that that is supposed to happen.
4:46. I think it's really dramatic so this is you know this but I'll say this for everybody's benefit this is very typical of a baby's brain. All the gray stuff is just brain. These little dark marks here are the ventricles. They're very small here as well. There's no space around the outside. Space in kids, that space is maxed out. It's pushing against the wall. That's actually how the skull grows. The growth of the brain pushes out on the inside of the skull and actually grows the bones of the skull so that's normal baby for a 20-month-old baby. This is that case report and when you zoom in like this and you didn't know that this was a baby you tell me if I'm wrong here but that looks very typical 4 and 80 year old on the right looks pretty typical for a 40 year old.
5:44. The big ventricles you look at the edge and you can see that would be called atrophy of the brain you can see this in and I don't read CAT scans of the head, but you can see it right away. That's not a healthy brain.
6:01. No, it's not, but if you put that in front of a radiologist and so that's an 80-year-old man, is that supposed to look like that he'd say yeah that's just a normal age-related atrophy the brain on the right would be a very normal for a 40 year old brain 35, 40 year old brain. Brain on the right of the child, there's no gap around outside the outside the ventricles are very small you can't even see the temporal horns. This one now you can start seeing that. It's already getting atrophied there is space around the outside the ventricles are a bit more pronounced around the brain stem pons and things like that. Now in the brain on the left it's much more pronounced much more atrophy huge ventricles big open wide temporal horns that's very typical for an elderly brain. But again this is a 6 month old girl of vegetarian parents with severe brain shrinkage atrophy due to B12 deficiency. This is a published case report from 1997. Retardation of myelination due to dietary vitamin B12 deficiency: Cranial MRI findings. Pediatric Radiology 27(2), 155-158. And so this is at 6 months old brain and it looks like an 80 year old brain on the right is 5 months later about a year old after daily B12 replacement so massive Improvement on that and if you flip those around and say okay that's a 40-year-old brain right and you would say yeah that's normal normal at age-related atrophy but we know this is B12 deficiency. And we know that B12 deficiency even as an adult you can lose a percentage of your brain matter the brain on the right is a 40 year old brain and you're losing half a percent, 2% every year you're damn right that's what your brain is going to look like at 80 of course it will but with proper nutrition, it doesn't have to and what I think is also striking here is that this one from an 80 year old brain, huge improvement. But it doesn't look like a one-year-old brain. Why the hell not? Did they just lose out on their ability to develop normally? Maybe. But also they are replacing B12 lost via their vegetarian parents. What about the vitamin D? What about the choline, the creatine, the carnitine, the DHA, the EPA, the cholesterol, the saturated fat, I'll bet the LDL is pretty damn low. It's not what you want. When you're trying to grow a brain that is predominantly made out of cholesterol. It's largely made out of it anyway. So I think that's why it looks like a 40-year-old brain instead of a 1-year-old brain like it should because . . . because it's not just B12 that she's missing. She's missing all these other things. So when we have MS patients, I have an MS protocol and we optimize B12 we get into reference ranges that are the studies have shown are optimal. We certainly get them to hell out of that "normal range" that can actually still cause demyelination. Because you're never going to regrow your myelin without [B12 and the other nutrients found in beef] if you're in vitamin B12, and things like that are so low that you'll get demyelination. It's never going to happen.
1:03. Also people think that artificial sweeteners just because they don't have sugar or calories in them means that it's okay to eat but really these are just chemicals we are not combustion engines we don't we don't burn our food for energy we are chemical factories and we use chemicals and they make chemical reactions.
1:18. When you put Stevia in your body this can lower fertility rate as shown in animal studies lowering the fertility rate by 55% compared to the control with just one serving of Stevia. This shouldn't surprise anyone because Stevia comes from the Stevia plant in South America that has been used in South America, in places like Paraguay, for over a thousand years as birth control. So why are we thinking that this is safe to put in the drinking Supply things like monk fruit sugar, also called Erythritol, has been shown in recent studies to have an increased risk of blood clots also even though they're artificial sweeteners and they don't contain carbohydrates they have been shown in studies to still trigger and insulin response and insulin is the fat storage hormone.
2:05. We've been told our entire lives that if you eat fat you'll get fat but that simply is not true. Your body has a limited capacity to absorb fat and after you run out of bile you will not absorb 90% or more of the fat that you eat. Your body has 5 organs working in concert just to absorb fat. Your stomach starts breaking food down. Your liver makes bile. Your gallbladder stores it. Your pancreas starts making enzymes, like lipase, to break down the fat, and the bile emulsifies it and it's absorbed by your small intestine. So why would we have 5 organs all working together to absorb fat if it were bad for us or harmful in some way? Our body knows what it's doing. Nature knows what it's doing. Biology knows what it's doing. And if our body didn't want that fat or didn't find it beneficial, it would not go to such lengths to absorb it in the first place. So if you under eat fat, you can actually slow down your progress. There are essential nutrients in fat that you cannot find anywhere else it's not just a calorie Source there's vitamin D3, K2, Retinol, vitamin E, DHA, EPA, choline, so many more things that you have to have in order to live and thrive. So reducing your fat not only reduces your energy intake, it also reduces your nutrient intake and you become malnourished. This in itself can slow down your metabolism because your body feels malnourished and it says, "Hey we are in a famine. We need to slow down our metabolism and ramp down our biological processes so that we don't run out of nutrients and energy." If you go really lean, like some people are advocating, you can actually get something called protein poisoning where you're getting the majority of your energy from protein when this breaks down it releases ammonia which then has to get turned in to urea in your liver and excreted in your kidneys if you overwhelm your liver's ability to turn ammonia into urea you'll get a buildup of ammonia and you can actually get quite sick this can cause hair loss low energy extreme illness and even yes rapid weight loss because you're very sick and in some cases it can even cause death so when some people are saying that the carnivore diet or a ketogenic guys making them sick or making their hair fall out maybe think how much fat are you eating also because your body has a limited capacity to absorb fat you need to know how much you're getting so you need to eat as much fat as you can that your body can absorb and then a little bit left over so that your stools are soft.
Ancestors ate high-fat megafauna (mammoths). Hunters today still target fat-rich animals--whales, seals, polar bears. Even Arctic fish are fat-rich. Large animals especially, Arctic species hunted in the Ice Ages, naturally carry a higher percentage of body fat. Significant inter-abdominal fat is also found in the omentum, mesentery, and around the kidneys. Healthy animals simply have more fat than starving ones.
Due to decades of processed food propaganda, people now discard nutritious subcutaneous and abdominal fat, consuming only lean muscle. Discarding this fat is not an ancestral practice.
Avoiding animal fat sacrifices vital nutrients--DHA, EPA, vitamins D3, K2, A, E, choline, cholesterol, and saturated fat--essential for neurological function and child brain development.
Weight stalls often stem from a "dirty carnivore" diet, [dairy, artificial sweeteners]. When issues arise, people wrongly blame high fat, forgetting high-fat carnivore initially drove their health and weight loss. Switching to low-fat risks malnutrition and protein poisoning, which can result in weight loss, but of the expensive health. As health suffers, people blame long-term ketosis on the poor health effects, even though this is against all the best long-term peer-reviewed evidence. See my YouTube video, Is Ketosis Harmful? for more.
Remember that your hormones like testosterone and estrogen are made out of cholesterol, and avoiding fat will make all hormones suffer. Eating carbs raises insulin and insulin resistance, which suppresses testosterone in men and estrogen in women.
Fat is an essential nutrient and is good for you. Don't avoid fat just because it's trendy and you don't want to give up dairy or sweets.
That is good for you, so eat the damn fat.
Dr. Anthony Chaffee discusses Ketogenic Diets here, here, and here.
Caffeine is a plant toxin. It's a neurotoxin and an insecticide that was developed to fry the brains of insects trying to eat that plant. And so that's probably not what you want to put in your body.
Coffee also has 150,000 other chemicals besides caffeine.
Search Assistant acknowledges 1,000 chemicals but is unable to identify all 1,000.
Wikipedia identifies some of them, including the insecticides,
The chemical complexity of coffee is emerging, especially due to observed physiological effects which cannot be related only to the presence of caffeine. Moreover, coffee contains an exceptionally substantial amount of antioxidants such as chlorogenic acids, hydroxycinnamic acids, caffeine and Maillard reaction products, such as melanoidins.[3] Chemical groups, such as alkaloids and caffeoylquinic acids, are common insecticides; their effects on coffee quality and flavor have been investigated in most studies.[4] Although health effects are certainly a valid taxonomy category, less than 30 of the over 1,000 compounds have been subjected to juried, health-related research (e.g. official potential carcinogen classification — see furans, for example), so health categorization has been avoided.
So you might as well at least get rid of those if you want the caffeine. If all you want is the caffeine, then just get the caffeine. And so what I would suggest is if you guys did want to have caffeine, maybe ditch the coffee side of things. Start with the caffeine pill. Take like a NoDoz, or something like that . . . .
2:48. We learned just how toxic plants were. I was taking botany. I was taking cancer biology and this was how plants defend themselves. They defend themselves by having defense chemicals that deter animals and insects from eating them. We learned that there were 136 carcinogens just in Brussels sprouts, over 100 in mushrooms, dozens and other vegetables that we eat on a daily basis.
My professor at the time was very much against eating plants we were quite surprised by this. But he even said himself that he didn't need salad. He didn't eat vegetables. He didn't let his kids eat vegetables, and the plants were trying to kill you.
3:27. So I just stopped eating plants. At that point, I didn't even realize it but I was eating a carnivore diet at the time [yes, a plant-free diet], and I felt absolutely amazing. My athletic performance just went through the roof. My mental acuity and sharpness got razor honed, and I just felt amazing. I ended up slipping off of it because I didn't realize how significant what I was doing was. That over the last several years I have come across information that says humans have been carnivores for quite a long time and that biologically+ we're most adapted to that or predisposed to that and we don't have these set up defenses against all the plant toxins then we probably used to have millions of years ago.
Get fattier grades of burger meat from the butcher, 70/30, 60/40, even 50/50. Now that's the ticket.

You got five organs all working in concert just to absorb fat.
Stomach starts breaking things down.
Your liver makes bile.
Your gallbladder stores that bile.
Bile is used to break down and emulsify that fat.
Pancreas makes lipase and other enzymes to break that down further, and then the bile gets absorbs that with the bile in your small intestine.
So why would your body be working so damn hard to absorb fat if it didn't want the fat? If that was bad for you, all it had to do was just turn one of those things off. Just don't make bile. You're never absorbing fat. If that were so bad for us, why wouldn't have nature taken care of that?
2:45 Two things that prove that humans were not meant to eat carbohydrates. First is insulin. Do you know that we have the wrong type of insulin for carbohydrates? Think about it. When we eat carbohydrates, our blood sugar spikes, insulin goes up but then blood sugar drops down too low because insulin keeps going, so we have to keep eating more carbs and more insulin. We keep having this balance throughout the day, and we can't get our blood sugar right as a result. Did you know that we had to reinvent insulin for Type 1 Diabetics and Type 2 Diabetics who require insulin? So instead of just giving
3:28 People who at more saturated fat had fewer strokes. Those who ate less saturated had more strokes. Hmm. I think I'll choose more saturated fats.
3:44 If you're cutting out fat as well, then the majority of your calories are going to come from protein. Even if you have excess body fat, you will still break down large amounts of that protein to either use as energy or store. As such, when you break down amino acids, you necessarily release a nitrogen group that then gets turned into ammonia and that's further transformed into urea in your liver. However, if you are eating too much protein, then this will build up the amount of ammonia that your liver has to process and it gets overwhelmed and you get a build of an excess of ammonia and this can actually cause very serious harm. This can cause liver damage, and your liver enzymes might go up where on a normal high-fat carnivore diet you will never see that. The ammonia can also cause organ damage to the rest of the body, cause neurological issues. You'll have extremely low energy. You can start losing your hair, and this is a symptom people have been seeing recently because they've bought into the whole nonsensical low-fat carnivore idea, and then they're told that this is probably being in ketosis and ketosis is harmful. But if it were harmful, then none of our ancestors would have been able to exist through the Ice Ages when there were no carbohydrates available. All the Inuits would be dead. And I would be dead because I've been doing this for over 8 years now, and 5 years in my early 20 have had no carbs in that entire time apart from what comes naturally in meat. However, when people are new to this and don't understand that ketosis is our natural metabolic state and not a harmful state,
Humans are apex predators, top of the food chain. What other apex predator eats salad? There are things in meat that you have to have that you cannot get from plants, but there is nothing in plants, or fungus, that you have to have that you cannot get from meat. So you have to eat meat, and you certainly don't have to eat plants and I would argue that you don't want to eat plants for optimal health.
