Paleo Anthropologist Daniel Lieberman On Sitting, Meat & Exercise

[@KenDBerryMD]

Great interview! I've enjoyed both of Dr Lieberman's books more than once. If we all keep searching and discussing, we will re-discover the proper human diet.

[@Viva-Longevity]

Thank you, Dr. Berry. 👏

[@StanDupp6371]

Why do you have to still search and discover and then re discover if you already have the answer and are already promoting it?

[@ssing7113]

There is no rediscovery. Times were far far different then. It was about survival and trying to ensure your genetic offspring lived. That’s it….. far cry from how we live today with so much food at a grocery store you could pass out eating Twix if you like You are meat because it was there and meant you lived another day. That has no relation to : people ate meat because it was good for them … we ate it because if you could kill it it meant calories. That’s it. Doesn’t mean cavemen knew nutrition 😂 secondly cavemen didn’t live to 85. We have a host off issues now which is : what is healthier given we can do near about anything now. Is it 5% meat. 20%. No meat. And testing shows no actual data beyond refunded food is horrible for you. Overload of processed sugar is bad. And overeating is very very easy these days because we have it everywhere and can drive in your car to get it. No more farming or hunting for the average human. Long gone are the days most most that you didn’t know if you could get enough calories to survive. We live in a world of over abundance and that’s messing with research because too many sick fat obese people eating too much to focus data purely on taking standard baseline of health and playing with it to see what is the best outcome. All on top of genetically some people have receptors and expressions shut off while others are flared from start along with inheriting parents baseline of metabolic issues….

@@StanDupp6371Because we never stop learning. A wise person learns from his mistakes. A wiser one learns from others' mistakes. But the wisest person of all learns from others' success. Dr. Berry has been learning and teaching a great deal, and his knowledge let him still promote low carb/ carnivore. He helps to fight diabetes, which the government fails to do. I am very certain if he ever finds out anything wrong about carnivore, he will talk about it.

[@Ananimous7777]

🤣🤣🤣 stop promoting carniovre then!!!! It messed my health up, my entire body got inflammed. I was brainwashed by you that it can cure all diseases, our ancestors were carniovre, the proper human diet bla bla.. but I experienced it and now I know how it actually works. It is an elimination diet, you feel good because you do not eat plants which your body can not metabolise well due to the root causes. The cure is addressing the root cause, not eliminating plants and putting yourself into remission. I know a lot knowa bout this diet and what health issues it can cause and diet is not everything, it is just a part of healthy life, there are other factors as well... You tried and felt well and then you started to promote it, which is wrong. To try to eat plants and see how you feel now, cure is be able to add foods back, if you can not add back, then it is just an elimination diet. Like you are lactose intolerant and you remove it and your symptoms go away... I can tell you lots of things which you are unaware of since I am more experienced now, but just stop promoting it please. You are carniovre cool, keep it up as long as you like, but do not promote it like a magic cure. It is not cure!!! I am now in a rabbit hole trying to save my life, I am not able to eat any plants anymore thanks to your magic diet

I knew a lady who lived to 110. She kept busy with activities up to the very end. The local newspaper interviewed her when she went out to vote during covid at the age of 109 and she wasn't using a walker or cane. In her kitchen she had a plaque that read, "As long as I'm alive I want to live!"

[@ssing7113]

Well this correlates as I tried to watch every documentary I could on oldest people. Only things I found was they weren’t hyper stressed about everything. They danced or sang in the kitchen. They enjoyed life’s ups and downs. And they were all self sufficient. And most of them either smoked or ate candy daily or drank 😂 Of course you are gifted genetically with this half already. The above I think pushes you to the finish line. Such as in there is some who have bacteria that can never get a cavity even if they don’t brush… where some had poor nutrition as a fetus and baby and have horrible teeth no matter if they brush and floss twice a day. I mean no comparison…..

[@ronhumphreys3762]

@@ssing7113 Yes the oldest woman on earth out of france famously smoked one cigarette a day for most of her adult life and also ate a bite of chocolate each day, her living to 123. But to add almost all very old people above 100 are small, which I guess helps, she was around 5 foot I think. Teeth it may be somewhat water. My wife never ever had a cavity and all her family pretty much the same, her mom I don't think she ever saw a dentist. They all lived rural within a desert environment. The water was all well waters source from rain water which filtered down through sand and rock. My wife lived with me in town during her first child birth which I expect may have stressed her calcium stores in some manner...developed cavities. The rest of the family living in towns not out there, seem to have normal dental problems like we all do. They both eat junk food and all the rest pretty equally the real only difference is the water. Fluoride they know helps, but perhaps it is some other minerals also added to that which help.Fluoride alone does not seem to remedy that entirely. I have noticed those in the northeast of america seem to always have bad teeth. Is it the tannic acid found in waters due to the rotting of leaves and such? I don't know but if someone has notoriously bad teeth, I find in america that is commonly a tell on location they lived in when young.

[@suzannealexander1]

Another outstanding video, Chris!! You are truly a gift from God!! 💝 I follow Dr. Lieberman's work closely! I am blessed to live among isolated ancient tribes, studying their diets, lifestyles, and longevity. I have been on a mission to determine if plants and animals have been essential to human health and longevity since the dawn of humankind. In my research and my in-person expeditions living with tribes, I have never encountered a tribe that is strictly vegan, nor an exclusively carnivorous tribe either. For instance, the Dani tribe in West Papua, Indonesia, is predominantly plant-based, with a diet rich in primarily sweet potatoes, including some greens and fruits, with pork or chicken consumed about twice a month. Similarly, the Maasai, often labeled carnivorous, include plants in their diets, such as seasonal fruit, honey, and other plants used for medicinal purposes, alongside their staple diet of raw milk, meat, and blood. The Vanuatu tribes, on the other hand, maintain a balance of both plants and animals in their diets, with a focus on fish, chicken, root crops, and fruit. The Inuits mentioned in the video, who are known for their high animal-based diet, do incorporate a variety of plants available in their region, including berries, herbs, roots, tubers, shrubs, seaweed, and predigested lichen and grass contents of caribou stomachs, which are used for food, teas, and medicinals. Every tribe I've lived with has emphasized the vital role of plants and animals, saying humans would not exist without them. When I share with the tribes that some people claim that plants are trying to kill us, they all laugh in disbelief, a testament to their wisdom. When I witness every tribe consuming plants, relishing in their nutrients and healing properties, it's truly tragic to see so much misinformation being spread on social media about plants being dangerous. It's a cause for concern when every tribe, every civilization has consumed plants, yet there are those who propagate fear about them. This misinformation misguides people and undermines the rich heritage of human nutrition and the tremendous health benefits of consuming plants. "Just because our ancestors evolved to do something doesn't mean it's healthy; that's what we call a Paleo Fantasy." (Dr. Lieberman) Brilliant and SO true!! The evidence is there: The epidemiological data and the vast number of studies conclusively show that vegetarians live longer than people who eat meat. Regarding Exercise - I asked each tribe what they believed to be the perfect exercise for humans. They all said humans are designed to walk many miles outside in fresh air and sunlight daily and tend to chores. They all walk about 12 miles each day. Many chop timber and carry wood and water for miles. There is no need for a gym membership when living out in the bush!! Additionally, a recent study focusing on the Hadza tribe in Tanzania suggests that human physiology is not well adapted to prolonged periods of inactivity, with time spent sitting increasing the risk of cardiovascular disease and mortality. Squatting postures elicit higher levels of muscle activity than sitting in a chair. Squatting postures elicit 20 to 40 percent of the muscle activity of walking while sitting uses about five percent. Squatting requires more muscle involvement than sitting passively, which suggests that our bodies are likely adapted to much more consistent levels of activity throughout the day. I can't imagine my life without squatting often throughout each day. Squatting is hardwired into our DNA! It's how we go to the bathroom out in the bush/jungle. It's part of being human! Even the tribe members in their 80s, 90s, and 100s still squat daily! Brightest Blessings, Suzanne Alexander Co-Author, "The Ancestral Diet Revolution"heroes

[@elsmooth12]

Chris, thanks so much for bringing to your audience this interview. It's always fascinating to listen to thoughtful folks in science and research disseminate their views and findings in an easy to digest format. It's always curious to hear certain sects making statements that basically conclude that the way we did it before is the way we should do it now, be it dietary pattern, exercise, medical treatments, or even government, education and other societally critical systems. This way of thinking ignores outcomes, and seems to put a ceiling on our opportunities to and react and adjust based upon results. It is far from a growth mentality, and really puts us all in a position to be left behind as other populations with a greater ability to critically think surge forward, improving the quality of life for their entire community. Anyway, keep up the great work!

My belief is the best source of knowledge is to get it from the people who actually conduct serious research for their careers, as Dr. Lieberman does, not people who just read research papers. Actual researchers are not always right, and we can all point to times where they weren't, but they are right more often than any other source.

I often have problems motivating myself to move. I overcome those difficulties by giving myself errands. I walk to meet friends, to health appointments, to the store, the library, to social events, etc., etc. Having a destination and a goal really helps. Also, two of Professor Lieberman's comments really jumped out at me: 1) "Just because our ancestors ate meat doesn't mean we should slavishly ape their behavior." and 2) "The evidence is clear, vegetarians (and vegans) live longer than meat eaters." That's enough for me.

Thank God about 10 minutes and 30 seconds in he said just because we evolved to do something doesn't mean it's healthy. I think the term is called antagonistic pleiotropy.

I love your second point, which is something I've often thought about. Even if it was the case that meat was wonderful for us, the truth is that it's very hurtful to the animals and the planet, and we should try to get out of that horrible predicament as soon as possible. We are one of the few species that can make such a decision (at least as far as I know, and at this time).

I recall that question completely stumped him. I often wonder if he persisted and how he is doing now.

We can’t run as fast or as far as most mammals,, we haven’t long talons/nails, nor sharp enough teeth.

His claim, that we can move beyond the constraints of our natural diet, is refuted by all data that exists in the subject.

We're talking a couple of tiny calcific foci. One of the four mummies they looked at had zero calcific foci. Only small portions of the vascular tree were preserved, and so the researchers said there was no way to grade the overall atherosclerotic burden. The researchers also mention that the Inuit had risk factors for vascular disease such has high rates of smoke exposure. The statement by Dr. Lieberman that the Inuit had "pretty much the same level of heart disease as Westerners" is certainly not supported by this study.

I got a standing desk for work over a year ago and haven’t looked back. I can honestly say that I sit less than 30 minutes a day and some days, I don’t sit at all, it’s either standing or laying down for bed. My hips are much better for it. I find it funny now when I go to my kids sports games and most of the parents are sitting down. I can’t stand sitting down and it’s on the same level of annoyance as walking (I would rather jog everywhere and even indoors if it was socially acceptable).

Re: will exercise make you live longer? You cannot divorce a person’s diet from their overall longevity and health. It’s a combination of diet and exercise and also environmental issues/other factors. Anecdotal: I had 2 workout partners as a teen. We were all super-fit. I have been eating whole foods vegan for 35+ years. My friends ate the standard American diet. One is obese and out of shape now at 66, the other died while training at 50. I have been training calisthenics for over 5 years and am very strong and still gaining. My doc said that my vitals are so good I’ll likely live into my ’90’s.

Ok so I was wondering what 30% of calories coming from meat actually looks like. Suppose we are talking about a man eating 2500 kcal a day. 30% of that is 750 kcal. Looking at Cronometer, to get 750 kcal from say venison you would be eating about a pound a day. That’s not too far off from what some “animal based” dieters are eating right?

I understand sweating is one of the best ways to remove many of these toxins from the body. Maybe in our new world of exotic substances we need to medicalise exercise as a way to reduce bodily buildup of these chemicals. Something our ancestors never had to do. Just a thought.

It makes you feel good. There really is no other drug with such beneficial pleiotropic effects.

[@mertonhirsch4734]

A major evolutionary adaptation in humans is that humans were able to pass on multigenerational knowledge, so longevity WAS very important in human evolution. It is also why we tend to honor grandparents rather than typically expect them to jump off a cliff when they turn 72. Nothing about his argument makes inflammatory seeds, grains and legumes (all of which result in fatal deficiencies in their natural form) something that humans would have developed the biochemistry and digestive mechanics to thrive on in large amounts. Natural soy and corn are fatal within weeks. Fermentation was required to detoxify them. Fruits and tubers are different but modern humans get 70% of their carbs from naturally toxic grains and legumes and 85%+ in America. Mattresses and antibiotics are not analogous to digestive and cellular biochemical evolution. Let me be clear, I'm not a carnivore advocate, but we know that humans evolved the biochemistry to survive on meat and fat, and natural health span decreased with agriculture, when other factors are controlled. Also the main difference in modern, farm raised meat to wild meat is higher omega-6 content due to them eating a grain and soy based diet.

[@someguy2135]

The major difference in wild animals that are killed for food and farm animals is the farm animals have been selectively bred to produce much fattier meat. The highest priced beef has more marbling which is marketing speak for fat

[@WilliamRoscoe]

I have questions. Knowledge is only passed on when it's multi-generational? How does that work? Seed, grains and legumes are inflammatory? Not according to outcome data in humans. Soy and corn are fatal within weeks? Where did you find that info? "Naturally toxic grains grains and legumes." What are you talking about? Every paleoanthropologist I've read agrees that humans ate whatever they could find, so apart from the arctic dwellers then everyone else grew up as omnivores, so our bodies would be adapted to an omnivore diet, not a carnivore diet. The main difference in modern meat is that factory farmed animals don't get to move around to save on production costs so get fat, plus the appeal of marbled meat to the consumer means that there's a lot more saturated fat in factory farmed meat.

[@Viva-Longevity]

@mertonhirsch4734 That all sounds very logical. He talked about the grandparent hypothesis which will be in his TEDx talk. But as he said, there is no way around the fact that populations who eat a lot of whole grains and legumes live longer than people who eat a lot of meat.

[@mertonhirsch4734]

@@WilliamRoscoe Way off on all of that. Legumes, Wheat and Corn Starch, along with milk and eggs are the most common food sensitivities provoking such things as asthma attacks and migraines. Non-processed soybeans are a trypsin inhibitor resulting in fatal toxicity to all monogastric organisms within a few weeks. Adeyemo, S.M.; Onilude, A.A. (2013). "Enzymatic Reduction of Anti-nutritional Factors in Fermenting Soybeans by Lactobacillus plantarum Isolates from Fermenting Cereals". Nigerian Food Journal. 31 (2).

ISBN 978-0-87055-111-6. Likewise, late stone age humans had to learn to prepare maize with lye to prevent fatality. In natural form, corn, legumes, most "nuts" are fatal. Wheat consumption correlated to several autoimmune diseases including thyroid, celiac, type 1 and type 2 diabetes and Cushing's. Grain fed "marbled" meat is actually higher in linoleic acid than meat from grazing animals. Corn fed pork lard is high in linoleic acid, while foraging pigs have more mono-unsaturated AND saturated fat content. It's the linoleic in corn and soy that raises the L.A. content.

[@mertonhirsch4734]

@@Viva-Longevity It is correct, and plausibly correlational though. Legumes and whole grains may improve longevity just because they reduce the tendency toward hypercaloric diets, which is good, but only indirectly the result of food choices. I for one have sensitivities to corn, wheat, oats and legumes, resulting in sinusitis and onset of sleep apnea which goes away when I stop. AND milk to be sure.

All those tubers they ate were low carb?

[@Lieutenant-Dan]

I think what's going on here is that humans are omnivores and have adapted to plant and animal foods in varying amounts depending on geography and availability. We can be healthy eating predominantly meat or plants even with the complete exclusion or extreme of carnivore vs vegan but I don't think that either is optimal for humans. Our biology is closer to plant eaters so I would hypothesise that we should be eating more plants with low to moderate amounts of animals foods. Obviously certain people are thriving on carnivore due to sensitivities to a lot of plants and auto immune issues. I've tried keto with a lot of animal foods and it does have its advantages. It seems to nulify cravings and blood sugar crashes. You just feel satiated all day with only one or two meals. Fasting is a lot easier to do with keto.

Another wants to cycle with Century each summer and another climbs specific peaks. It may not even be big things as one can be inspired by their local 5k calendar or a powerlifting event.
