Harvard Professor: They’re Lying To You About Running, Breathing & Sitting! - Daniel Lieberman 

If you enjoyed this episode please do us a favour and give it a like 👍🏾helps us massively and determines what you guys want in future episodes

One thing I have learnt from listening to all your podcasts, is that EVERYTHING IS GOING TO KILL ME! Caffine, breathing, sitting, anxiety, depression, meat, dairy, processed food, oats, protein, medications, technology, social media, childhood trauma, retireing, poverty, sugar, harsh chemicals!

As soon as you stop watching these podcasts the world start to look better again 😅

I’ve recently gotten off social media, decluttered my studio apartment that was a victim of overconsumption, cut a credit card that was my accomplice of overconsumption, and did a three day fast for mental clarity. My realization is that LESS is MORE. I have more energy when I have SPACE to move and I’m on my phone LESS! I’m going to keep pushing on, even when life seems “boring” (peaceful)

Does chronic anxiety caused by watching these podcasts reduce my lifespan?

00:00 🌐 Evolutionary Mismatch Diseases: Chronic stress, obesity, heart disease, and many cancers are considered mismatch diseases caused by our comfortable, sedentary lives in a world of abundant choices. 01:25 🏃‍♂ Actionable Steps for Health: Combatting mismatch diseases involves being physically active, avoiding prolonged sitting, and embracing activities that challenge our bodies, fostering better endurance and overall health. 02:49 🤔 Understanding Human Evolution: Dr. Daniel Lieberman, a Harvard Professor of Human Evolutionary Biology, explores how studying human evolution helps unravel the origins of health issues and offers solutions. 03:48 🍽 Evolutionary Diet: Humans are ultimate omnivores, evolved to eat a wide range of foods. While hunter-gatherer lifestyles offer insights, a simplistic return to a paleo diet is termed a "Paleo fantasy," as evolution is not a one-size-fits-all guide to modern health. 07:20 🏹 Hunter-Gatherer Transformation: The shift to hunting and gathering around 2 million years ago marked a crucial phase in human evolution, influencing our bodies, diet, and cooperation as a species. 15:13 👃 Evolution of the Human Nose: The external nose, evolving around 2 million years ago, is considered a humidifier, improving air contact with nasal mucous membranes, crucial for moisture retention during breathing. 17:42 💤 Modern Breathing Challenges: Discussion on modern breathing issues, such as mouth breathing, sleep problems, and potential solutions, highlighting the importance of understanding our evolutionary adaptations for better health. 18:09 🏃‍♂ Nasal breathing during running is not supported by evolutionary evidence; humans evolved to breathe through their mouth while running to dissipate heat efficiently. 20:01 🦎 Human sweating, a unique adaptation, allows effective heat dissipation during physical activity in hot environments, providing an advantage during hunting in the heat of the day. 23:20 🧠 The increase in brain size in humans is linked to the transition to hunting and gathering, providing more energy for brain development through improved food processing and cooperation. 27:27 🍼 Infant body fat is crucial for providing constant energy to support the high metabolic demands of a growing brain, and fat storage is connected to brain development and reproduction. 32:52 🤯 Stress-induced cortisol elevation can lead to visceral fat accumulation, causing inflammation and contributing to various diseases; stress is a risk factor for health issues. 34:29 🩸 Low body fat in women due to dieting or intense physical activity can disrupt hormonal balance, affecting menstrual cycles and fertility; energy availability plays a crucial role in reproductive health. 36:18 🏋 Physical activity significantly reduces breast cancer risk in women; sedentary lifestyle linked to abnormal hormone levels. 37:13 🤰 Body's sensitivity to energy influences reproductive decisions; low energy levels signal a suboptimal time for pregnancy. 38:09 ⚖ Chronic stress, cortisol, and mismatched environments contribute to various modern diseases; stress management crucial for health. 39:18 💔 Mismatch diseases, such as heart disease, diabetes, and cancers, stem from inadequate adaptation to modern lifestyles. 41:25 🌎 Most people in the Western world likely to die from mismatch diseases; heart disease and cancer top the list. 42:20 🥗 Diet and exercise can prevent or alleviate many mismatch diseases like heart disease; lifestyle choices play a crucial role. 43:00 📚 Writing a book on diet from an evolutionary perspective; aims to help people make healthier and more informed dietary choices. 46:18 🔄 Cultural evolution outpaces biological evolution; rapid environmental changes lead to mismatches between biology and modern lifestyles. 52:08 💊 Overreliance on treating symptoms rather than preventing causes in modern medicine; the need for a shift towards preventive healthcare. 53:18 🦠 Cancer is not solely a mismatch disease; linked to energy levels, physical inactivity, and exposure to carcinogens in modern environments. 55:08 🍽 High energy levels, influenced by diet and physical activity, correlate with increased breast cancer rates. 56:31 🌍 Cancer rates among Hunter-gatherers are believed to be much lower, possibly due to fewer menstrual cycles and higher energy demands. 57:25 🚼 The number of menstrual cycles influences breast cancer risk; more cycles, higher risk. 58:30 🤰 Hunter-gatherer women, often pregnant or nursing, experience fewer menstrual cycles, potentially reducing cancer risk. 59:12 🏃‍♂ Rapid weight loss from diets like keto is often due to water loss, not fat loss. 01:00:47 💡 Fat is essential for life, storing significant energy. Insulin helps store fat in adipocytes; hormones regulate fat retrieval. 01:05:34 ⚖ Chronic inflammation from overpacked fat cells can lead to various health issues. 01:06:02 🔄 Fasting and exercise share common gene activation in response to negative energy balance. 01:08:30 🍔 Keto diets, by relying on ketone bodies instead of glucose, may have short-term weight loss effects but are less proven for long-term success. 01:10:22 🛋 Excessive comfort, particularly in childhood, may contribute to physical weakness, impacting skeletal health and overall fitness. 01:11:45 💪 Inadequate exercise during youth contributes to lower peak bone mass, increasing the risk of osteoporosis later in life. 01:13:09 🦴 Loading bones through activities like playing tennis can lead to asymmetry, where the arm used to hit the ball has significantly thicker bones. 01:14:18 🦷 Chewing hard food, like resinous gum, may positively impact jaw growth and reduce issues like malocclusion. 01:15:28 🌍 Puberty age has changed due to energy availability; more energy leads to earlier puberty. Historical data shows this shift in various populations. 01:17:17 🪑 Prolonged sitting can be an issue, especially if combined with sedentary leisure time. Regular breaks and not sitting excessively outside of work are recommended. 01:19:21 💪 Back strength, particularly endurance, is crucial for preventing back pain. Weak backs with low endurance are prone to fatigue and spasms. 01:21:12 🔄 Modern living is filled with mismatched elements. Being aware of these mismatches helps make better decisions regarding diet, physical activity, and lifestyle. 01:23:15 🚑 Treating symptoms of mismatch diseases without addressing the underlying causes contributes to a vicious cycle, worsening the overall situation. 01:27:23 🤒 Overly sanitized environments can lead to weakened immune systems and an increased risk of allergies and autoimmune diseases. The hygiene hypothesis suggests that exposure to normal pathogens is essential for a robust immune system. 01:29:28 🏃‍♀ TV presenter Deina McCo was inspired to run after listening to the podcast with Dr. Daniel Lieberman, emphasizing the impact of conversations on lifestyle. 01:30:12 📚 "The Story of the Human Body" by Dr. Daniel Lieberman is considered essential reading and is used in schools and educational institutions. 01:30:25 ❓ A closing tradition involves the last guest leaving a question for the next guest. The question for Dr. Daniel Lieberman is, "For what would you be willing to die today?" 01:31:13 💔 Dr. Lieberman expresses that he might be willing to risk his life for the people he loves and cares about, and potentially for the greater benefit of humankind. 01:31:57 🤔 Reflecting on the question, Dr. Lieberman discusses his initial response about what he would die for, including family and the complexity of the idea of sacrificing one's life for a cause.

I love that he let's his guests speak! He asks great questions and leads the discussion... I hope that doesn't change.

my grandfather died at 102 with half century diabetes my father at 70, the one lived through WW1 WW2 (as soldier) smoked and drunk everyday and my father died from stress to attain material things while my grandfather had a very different attitude towards life quiet and optimistic and close to nature.

As a retired academic from a family with generations of intellectuals, I have noticed that very clever people are often wrong in their conclusions. On the other hand, ordinary people, informed by tradition, experience, and muddled thinking often get things more or less right. It’s worth bearing in mind when listening to very knowledgable experts.

Why no-one talks about the fact that these days in Western countries people do not only eat ultra processed foods which have no nutrients, but they also eat for many other reasons than for being hungry. Most of the people I know - who are over weight - eat at meal times, but also when they are bored, happy, unhappy, sad, to celebrate something or to "release stress". Those of my friends who eat few warm meals a day and few snacks only if they really are hungry, are all normal weight. Also I have lived on the country side in Tanzania, East Africa, with a local family and there people only ate a light breakfast, two warm meals and rarely snacks which if eaten, were small amount of fruits or peanuts or cashew nuts. NO-ONE was overweight. So in the West people these days are using food to almost everything else than to treat their REAL hunger!!

I just LOVE listening to this man. Thank you for this interview and such great guests on this podcast❤

Thank you Daniel, and Steven, for a thoroughly enjoyable podcast. I was struck not just by Daniel's knowledge and his ability to explain things in ways a layman can follow, but by his humility, a quality quite rare among talking heads on RU-vid. He was at ease in saying he didn't know the answers of questions, and when his remarks were merely a hypothesis. And I had a good laugh too when he admitted to also being someone who decontaminated himself after a gym session.

I'm 47, British, no car, live within my means, focus on my inner journey and show gratitude everyday, not on any tablets or have any issues like bad back. What I observe is the majority of people I am surrounded by have depression, drink all the time, eat processed food and most women have inflammatory diseases. They all look to Western medicine but don't look at their lifestyle and diet to improve their lifestyle. It's astonishing how many WANT a label to give them a purpose. I work in the NHS so see it everyday.

This episode is for sure one of my favorite one ever. As we all know, health is wealth. We live in an age of excess and our lifestyles have led to health crises. Making meaningful changes and balances can help us improve our wellbeing in the long run. Thank you for bringing this to us.

I love to listen to y’all . I really learn a lot from it, so much knowledge . Thank you for your time to sit and explained with questions and answers. Thank you🙏

I’m nearly 50 and I’ve never seen body shapes like we have today. Some on very young people which is quite an achievement to look the shape of late 60’year old in your teens.

I think the old adage that moderation is the key, is closer to living a long healthy life. Balance.

Just want to say thank you to your team and all the work you put in 💙💙💙❤️❤️❤️ for really interesting guests and mind-provoking discussions. Thank you 😊

He’s spot on about sitting for work then also for leisure time being just about the worst thing you can do. You can end up with nerve issues from constant pressure from the surrounding tissues, weak/tight muscles, etc. even when you’re young. If you have a long-hours office job you’ve absolutely got to be active the rest of the time.

Dr Lieberman gave a great 7 minute talk on exercise here on RU-vid. It was one of the best talks on the topic I’ve heard.

This is one of the greatest guests you have had On since I subbed. Brilliant observations , grounded in reality. I rarely agree 90% with "professors", but this man is sharp . And you are a host capable of bringing out the best and worst in your interviews . Good fricking video. So much truth here. Take if from a healthy 60 year old.

This was a very interesting discussion. My friend is a nurse and she cleans her house to the nth degree, disinfecting and bleaching wherever possible. All 5 of her children have asthma. I used hand sanitiser one or twice during the pandemic but stopped as it adversely affected my skin. I have a severe form of eczema. I have several autoimmune problems caused, I believe, by the ultimate sanitiser - chemotherapy. I firmly believe my cancer was if not caused by then greatly aggravated by being very stressed and having high anxiety

I could listen to Daniel for hours!! I love this guy. Great episode ✨

Dr lieberman talk is so educative as he breaks nature down for us its so awesome. But it amazes me how nature is so perfect and flawless.

Love his simple thinking about eating and breathing. People make a business of obsessing over individual elements of the human body, nose breath, zone 2, specific diet, whatever it is.

Our breath is our gateway to tapping into our nervous system. Breathing less and nitric oxide nasal breathing has improved my sleep, athletic performance and my ability to regulate my emotions.

So many think old age is a time to take it easy. For me I walk and even jog even more than before. Really push myself physically. Handwash my clothes, gardening and building repairs. I meditated for 50years......thank God.

What a great, visual way of explaining how our body works . Thanks.

Hi Steven, thank you for your podcasts. I always learn something new and your channel is one of my favourites❤❤❤❤❤❤❤

I came to nose breathing through my own problems with catarrh and allergies when I was young. I carried this into running as I realised that it helps conserve water, avoid breathing in damaging cold, winter air and other impurities/dust. Mouth breathing is for ‘running for your life’, when maximum speed, maximum air intake are essential and trump healthier routine. So, if you want to sprint, yes, you will need to mouth breath for performance but there are consequences to routine mouth breathing. For endurance running, especially in hot, relatively dry areas where it likely evolved, nose breathing should be the norm, with only occasional bouts of mouthbreathing to power short sprints.

This Podcast is Dope !! I just can't stop listening it! Thanks Steve !!

What a gentleman. No doubt every student who takes his class is blessed by this genuine man. Great interview!

Absolutely fantastic interview.

Favourite podcaster. Big up the uk

My favourite episode so far. Nothing faddy. Great holistic perspective that ties together a number of interesting topics ❤

Thank you for your amazing interviews! I’ve read so many of your interviewees, and I appreciate the amount of care and respect you show towards each guest, ALWAYS letting them explain, talk and complete their thoughts without interruptions. THANK YOU.

This was by far one of my favorite podcast episodes on RU-vid. I really like this professor. He has a lovely voice and great at explaining concepts. I’m a doctor and I really enjoyed this episode ❤

Entrepreneurs should use this episode as a guide to building products and services that genuinely impact human lives based on data. Good episode.

Fascinating guest, thank you 👍🏼

This is hands down one of the best podcast episodes of any podcast series I’ve ever listened to. Daniel Lieberman’s erudition is a wonder and a joy.

Fascinating interview! Thanks for sharing.

I was a strict vegan for 8 years, my 'reward' was a horrible disease called Systemic Mycosis which only started to turn around when I began eating meat again. Yes we are supposed to eat meat, that's just the world we live in.

I have PCOS and so much of this applied to me: Progesterone plummeting during dieting; abdominal fat causing inflammation; so, so much!

These podcasts are awesome. So much information.

That was really enjoyable and I appreciate that when asked about a question in which he wasn't an expert, he either didn't answer or prefaced his answer with acknowledging that he isn't a subject matter expert. Love to see it.

The gift of cancer if your survive is radical life and friend changes. Much love CEO viewers.

This man is fantastic and totally calms down the hyped up quick fixes and extra worries that arent based on any data!! Yes DR!!

❤❤❤❤❤❤ Stephen thank you for being such a wonderful interviewer, for asking the questions I’m thinking with such minimal interruption and letting your guests impart their knowledge 💞💞💞💞💞

Thank you for the incredible podcast! I've learned so much, and your insights have been invaluable. Additionally, thank you for the book suggestion-I've just added it to my library. Steven, your work has been a constant source of inspiration for me over the past couple of months. The way you ask the questions I've always wanted answers to makes me feel like you're becoming one of my best friends hahahaha.....Your approach is both engaging and enlightening. Thanks again for your fantastic content!

really really nice and i think Steven was doing a great job in getting actionable advice. great one!

This guy is the voice of reason. Very refreshing to hear.

This is loaded in helpful and life changing informations, i love this podcast 🤩

Steven, you are my favorite YT channel. I love learning and love your choice of guests/topics. Love YOU!!!! ❤

Daniel Lieberman, compelling & entertaining. Great choice.

I've learnt a lot about sweating today. Great episode!

Your content is amazing.... Keep up the good work. God bless you.

Awesome Harvard Professor’s Analysis!

So, can we just have Professor Lieberman on seasonally? As someone that ended 2022 reading The Story of the Human Body, Exercised, Sapiens & Homo Deus 2023 was a fantastic outward & inward study. I was already pot committed to the Fitness Plus program & cogitated on the absence of combat sports in the lineup. Everything was ticked off something covered in Exercised… Then Monday, January 9 hit & Kickboxing was added and I pair it with Pilates. Looking forward to reading Dr Lieberman’s next book. But I purchased & Consumed the 1st few Blue Zones books a decade ago & have been looking around KNOWING what all the Game of Thrones readers where feeling.

I would love to see some of the professionals that came here in a debate together as they complement each other in many cases, that would be amazing!

Thanks Ivor for your insight

While this information is no doubt very valuable - each guest says different things. I want to improve my health but I honestly don't know what to follow anymore.

I've been tuning into your episodes. Timely one for me today as I have had breathing problems for a long time and didn't realize I had a deviated septum until meeting with an ENT. I started wearing nose tape which has been incredibly helpful. I can actually breathe again! This isn't a long term solution though of course as it's drying out my nose. The evolutionary history is amazing regarding the brains and our breath through energy and selection processes way back.. hmm. Thanks!

Hey dude thank you so much for your podcasts.. very informative.. and one thing I love about your content is that you come prepared and ask the most relevant questions which I keep on getting while I am listening to these podcasts..it's like as if you read my mind while you are asking these questions just at the right moment.. Thank you so much for the hard work you're putting in

Thank you very much for new ideas , I also do additional search on the internet about ideas I get from this channel to have a further understanding

Omg! About adipocytes busting causing an immune reaction just hit home for me, no wonder diabetics have so many issues. Absolutely eye opening! The reason keto works for epilepsy is the reduction in inflammation, carbs in folks with certain factors causes increased inflammation.

This podcast reads like a book and I looove that. I don't know how to make this make sense, but I get it so that's cool ❤❤❤😅

Daniel is a legend!! Makes everything seem so obvious. Thumbs up 👍

So...eat a balanced diet, exercise, and reduce your stress.

🎯 Key Takeaways for quick navigation: 00:00 🩺 *Daniel Lieberman, a Harvard Professor, suggests that many modern health issues, such as obesity, heart disease, and certain cancers, stem from mismatches between our current lifestyles and our evolutionary past.* 01:25 🏥 *To reduce the risk of mismatch diseases, Lieberman recommends two actionable steps: subscribing to the RU-vid channel for more information and making lifestyle changes to incorporate more physical activity.* 02:21 🧬 *Daniel Lieberman's role as a professor of human evolutionary biology at Harvard University involves studying how and why humans are the way they are, particularly focusing on the evolutionary aspects of health and disease.* 03:48 🦍 *Lieberman challenges the idea of human fragility, highlighting human adaptability and physical capabilities, such as endurance and the ability to consume a wide variety of foods, including meat.* 05:55 🍖 *Humans have been eating meat for at least two and a half million years, and it played a significant role in our evolutionary history, contributing to our adaptability and survival as a species.* 07:48 🍽️ *Lieberman emphasizes that human dietary preferences and adaptations are not solely based on health but are primarily driven by reproductive success, leading to our omnivorous nature.* 11:01 🏹 *Hunting became a significant part of human ancestors' lifestyle between three and two million years ago, marking a crucial evolutionary shift that influenced our physical and behavioral adaptations.* 15:13 🌬️ *The external nose in humans, developed around two million years ago, serves as a humidifier, aiding in trapping moisture and regulating temperature during breathing, contrary to mouth breathing habits.* 18:09 🏃‍♂️ *Nasal breathing during exercise is not supported by evidence; breathing through the mouth helps dissipate heat efficiently, crucial for runners.* 20:01 🦎 *Panting and sweating are vital cooling mechanisms in animals, including humans, during physical activity.* 23:20 🧠 *Brain size expansion correlated with the advent of hunting and gathering, enabling more energy consumption for brain development.* 27:27 🍼 *Human infants are born with high body fat to support brain development, with fat acting as an energy reserve for brain function.* 30:47 🍔 *The body's response to stress and negative energy balance includes increased cortisol levels, leading tofat deposition, particularly in visceral stores.* 34:01 🔄 *Energy availability affects hormonal balance, impacting menstrual cycles; low energy availability can disrupt reproductive function.* 36:44 🔄 *Our bodies are sensitive to energy levels, influencing decisions like reproduction based on available energy resources.* 38:09 🌱 *Chronic stress, a mismatch in modern environments, leads to various health problems, highlighting the importance of addressing lifestyle factors.* 41:25 🩺 *Mismatch diseases, caused by environmental changes outpacing biological evolution, are major contributors to modern health issues like heart disease and diabetes.* 42:06 💊 *Treating symptoms rather than preventing diseases leads to a cycle of dependence on medical interventions, highlighting the need for preventive measures.* 46:31 🔄 *Rapid cultural evolution has created mismatches between our biology and environment, leading to conditions like myopia and dental malocclusions.* 51:54 🩸 *Cancer, influenced by lifestyle factors like diet and physical activity, is a result of mismatches in energy levels and environmental exposures.* 55:36 🌍 *Environmental changes, particularly in energy intake, significantly impact cancer rates, emphasizing the role of diet and lifestyle in disease prevention.* 55:50 📈 *Cancer rates correlate with GDP: Higher GDP countries tend to have higher cancer rates, possibly due to factors like increased physical activity levels and dietary changes.* 56:18 🩺 *Lower cancer rates among hunter-gatherers: While there's limited data, it's believed that cancer rates are significantly lower among hunter-gatherer populations due to factors like fewer menstrual cycles and different lifestyle patterns.* 57:12 🚺 *Menstrual cycles and breast cancer: Increased menstrual cycles due to factors like modern family planning methods may contribute to elevated breast cancer rates due to exposure to high hormone levels.* 59:12 🏋️‍♂️ *Fat and energy storage: Fat molecules store a significantamount of energy, and excess energy is stored as fat in adipocytes. Insulin plays a role in transporting triglycerides into fat cells for storage.* 01:00:47 💡 *Fat storage and breakdown: Our bodies constantly store and burn fat based on energy balance. Fat cells swell like balloons when storing fat and release fat when energy is needed.* 01:03:32 🩸 *Visceral fat and inflammation: Excess visceral fat can lead to chronic inflammation, which contributes to various health issues like cardiovascular disease, insulin resistance, and even Alzheimer's.* 01:08:15 🥩 *Ketogenic diet: Keto diets involve consuming high-fat, low-carb foods, leading the body to use ketone bodies for energy instead of glucose. While it may promote short-term weight loss, its long-term efficacy is debated.* 01:11:04 🏃‍♂️ *Physical activity decline in children: Children today are less physically fit and active, leading to concerns about skeletal health and increasing rates of conditions like osteoporosis.* 01:13:35 💪 *Skeletal response to loading: The skeleton responds to demand, with increased loading leading to bone adaptation and potential increases in bone thickness and strength.* 01:13:50 💡 *Loading bones through chewing hard food can influence jaw growth, affecting dental health and malocclusion rates.* 01:15:14 🔄 *Puberty age variation is linked to energy availability during growth, affecting reproductive transition timing.* 01:17:03 🪑 *Prolonged sitting can be detrimental to health, especially when combined with leisure time sitting, emphasizing the importance of regular breaks.* 01:19:08 💪 *Back pain often stems from weak back muscles rather than acute incidents, highlighting the importance of muscle endurance for preventing pain.* 01:20:45 🤔 *Understanding mismatch diseases leads to actionable lifestyle changes, such as increased physical activity, balanced diet, and minimizing exposure to modern environmental factors.* 01:25:06 🛡️ *Be skeptical of cosmetic and hygiene products, as many may not offer significant benefits and could have unintended consequences on health and microbiome.* 01:27:23 🦠 *Excessive sanitation may weaken the immune system, leading to increased susceptibility to allergies and autoimmune diseases, supporting the hygiene hypothesis.* 01:29:14 📚 *Daniel Lieberman's books, particularly "The Story of the Human Body," are praised for their educational value and relevance in schools, highlighting the importance of updating scientific knowledge.* 01:30:25 💭 *Considering what one would be willing to die for reveals personal values and priorities, often centered around loved ones and potential benefits for humanity.* 01:31:13 🤔 *The willingness to sacrifice one's life for a cause or idea is a complex decision influenced by various factors, including circumstances and personal beliefs.* 01:31:57 💡 *Personal priorities may include willingness to sacrifice for family members or partners, while the idea of sacrificing for an abstract concept like an idea requires deeper reflection.* Made with HARPA AI

You are helping many people...life and relationship are so complicated. At least you are making them known. Finding solutions can be very tough. Anyway, thank you for your immense work to support humanity!

Great stuff Steve, watching your podcast has been the highlight of my year so far..Thanks.

😂😂 The irony of Steve being given advice to “be skeptical” of all those trying to sell us the latest “health product” IIMMEDIATELY after his straight faced commercial for Huel’s green powder product 😂

Its a fantastic channel

I can report that years of shift work and poor sleep have wrecked me. On top of that working in mental health adds to the stress.

Probably one of the most explanatory video I have ever watched about modern health struggles, and inflammation in particular. I have gone to the doctor for YEARS (not to say decades !!) without one single doctor having been able to explain me why I was always so exhausted and feverish. They sold me tons of anti-inflammatory medication and other stuff, but could not explain to me what exactly triggered the inflammation, and how I could avoid being sick in the first place. Every single year, I came back with the same questions, and every year they just looked at me like it was nothing serious anyway. It is many years later, when I heard about fasting as the last solution to get rid of my chronic pains, that I started finding the beginning of an explanation. And it's only today, in this very video, that I could really figure out the role of fat cells in inflammation, and WHY it is so risky to accumulate belly fat ! The immune reaction that follows fat cells "explosion", the production of cytokines and suchlike triggering inflammation, and then the inflammation creating heart diseases, brain dementia, hormonal problems such as insulin resistance, diabetes, etc. A million thanks to you for this interview, and another million thanks to Dr Lieberman !!

The surge of estrogen and progesterone part of this conversation is incredibly intriguing. I hear, for example, that female dogs who do not bear children typically end up with endometriosis or some form of cancer--kind of a use it or you lose it situation. It's interesting to think of it as, constantly menstruating is exposing your cells that are sensitive to these hormones could increase your risk of cancer. But what does this mean for people who take birth control pills? Especially those who were advised to take them due to androgen imbalances like PCOS sufferers?

Comfort causes cancer Stress causes heart disease Conclusion: You cant win. Jk❤

I like this man ❤he seems open and honest and unbiased. Great interview

Brilliant! Sensible and informative. Thank you!

Fascinating podcast. However, i'm not convinced its the estrogen that is CAUSING the breast cancers, more likely high insulin. The volume of breast cancers in post menopausal women is far higher than those of child bearing years and yet the circulating estrogen has plummeted!

I have been doing 50 jumping jacks in the morning before I start my day. Few years now. I feel like it does get my ..engine..going. Puts me in a better mood too. Kinda cool

I think this is the best episode in your video list. Very engaging!

I have adopted this philosophy in my life in my late 20s despite my chronic pain, doing the best I can to make up for the more sedentary and mindless life I lived before. I’m working graveyard shift now and trying to be as healthy as possible. I get up and walk all the time, I stretch, I eat very little processed food. Our culture is very unnatural on our bodies and it takes a lot of effort to fight it especially once you already have developed health conditions.

If we evolved to eat meat as Dr. Lieberman says then we could eat a totally uncooked steak with our bare teeth and digest it easily. We evolved to have the brains to be able to cook meat and that made it possible (in about 48 hours) to digest it. We're still digesting meat way down in the intestines whereas a dog or other carnivores polish off meat in a few hours with their much more powerful stomachs.

It seems to me this morning (within reason) that if we reorient ourselves to helping others including our environment, that health will arise. If not physical, certainly mental and spiritual, making any physical ailment more manageable. A few years ago I recall watching a documentary about an ancient individual who's bones showed signs of arthritis. The video depicted the man rubbing his shoulder or elbow because it must have bothered him, yet we know people can have full-on Alzheimer's physiologically without being bothered by symptoms. We all are made to die of something. Obsessing over it robs us of living and the joy waiting to be felt by simply wanting it for everyone. Cheers.

i noticed this, in the 30s my back started to hurt a lot, like, 2 hours sitting my back was already aching, then i started training in the gym, and my posture got better and my back stoped aching, the feeling was my muscles in my torax got better keeping me straight

Man I love listening to your podcasts

Barto is back with another banger of a pod

love DOAC and this guest seems sound! so many expert guests contradict each other, which would be an interesting topic to diplomatically raise at one point

Harnessing fire for heat in colder climates, and for cooking food was a major advancement in the development of our species. I feel this idea was overlooked in the dialogue.

I agree about the wearing less shoes part. Eversince i developed neuropathy and arthritis in my feet, wearing shoes less has made an incredible improvement.

The sign of the times is that we’ve turned the value of individualism (being one’s best best self so as to enable the creation of a better world) into hedonism. We eat heavily processed sweets because we can, we ditch having a family in favour of dating multiple partners because we can, we sit around because we can, we hop from one job to the other instead of patiently getting good as something because we can. Just because we can do all these things it doesn’t mean that we should abuse those freedoms. If these attitudes won’t change and if bio whole foods won’t become the new normal that’ll make future generations look back at our eating habits and go “eww” then we are on our way to decline. I hate to say this because I do love our world more than any other one available out there, but we either give up on hedonism once more knowledge like this becomes available and implemented or we just get sicker and lonelier.

interesting discussion. some made sense to me and some didn’t. how did hunter gatherers have only around 50 cycles? that means they would always be pregnant. and when you’re pregnant you also are having many many more hormones running though your body. not having a period cycles doesn’t equate to not having hormones coursing though you .

Brilliant interview. Brilliant guest. Thank you!

I enjoyed this episode a lot !!!! So much knowledge, many new insights for me, thank you !!!

this podcast is amazing, it has become the number one friend for my morning walks, you get so many information and in such a easy way, both entertaing and educational. Everyone who does not hit that suscribe button - you are missing so much. I am so happy that i discovered it

Cancer among Banglash people in UK might be connected with wit D deficiency. Their darker skin takes less sun than it used to in Asia causing permanent inflamation.

I was about to shut off my comp just when I saw this. Got hooked to it 1 hour. Saving the renainder for tomorrow night.

In the 1960's, there was a government program to encourage people to walk 50 miles. You were supposed complete the walk in a certain number of hours. My older sisters tried it, and I forgot how many miles they made before giving up. I think the problem was that the shoes were not as suited to long walks, and they got blisters.

59:00 Keto you lost 3lbs water in first few days, 2 months is no way all water weight loss. It bounced back because he didn't give enough time to reverse insulin resistance to be able to tolerate carbs again without gaining weight.
