I certainly like Peter, and a lot of what he says. It’s nice that he is now on the exercise bandwagon. It is ironic that he is against pumping nitrogen into the soil. Analogous is humans popping supplements into the human body. There’s no way you can turn around from pumping N in the soil because of the world’s population size.

At this stage, I'm going to be doing 'me'.

When Dr. Attia said he changed his mind on exercise, I thought 'great', only to find he still gets in 12 hours or so a week.

[@mfkleven]

Forgive me, but I think you guys are missing the forest for a few evolving trees. The bottom line, in fact, is that we absolutely do know how to eat, exercise, sleep, etc. to be healthy. The fine-tuning of details to “optimize” health (like fasting and metformin, plant-based vs keto) are more debatable and will continue to evolve as science progresses. But the fundamentals, the vast majority of Dr. Attia’s message, and the greater message of all reliable healthcare providers has not changed. To throw up your hands and abandon the pursuit of truth because the details get refined over time is to misunderstand the process-and power-of science.

[@RichardHarlos]

@@mfkleven I don't think the point of the original comment was to 'abandon the pursuit of truth', rather, that we not get bogged down in the seemingly fluid conclusions as our science refines our understanding over time. Even in this somewhat reductionist view, it can be easy to miss the mark. For example, plant-based vs carnivore is a big divide. One would think this would be a simple matter to deconstruct to a definitive conclusion and yet... the jury is still out. I initially leaned toward vegan as a matter of personal conscience. I found the nutritional challenges too hard to accommodate, so I slid a bit and looked at vegetarianism. While not strictly a vegan perspective, it seemed much easier to realize a more complete nutritional intake but without jumping through so many hoops. Still, I never felt like, 'A-ha! This is the answer!' so I began learning about paleo, keto, and eventually carnivore. And here's the thing: every food-selection motif has it's evidence supporting it, and if not criticizing the alternatives, at least framing them in a way that makes them seem 'less-than' whichever one happens to be at the podium in any given moment. At the moment, my current perspective is very much agnostic: I don't know which motif is better, or even if it's reasonable to suggest that one outshines all the rest. Are they merely different paths to the same outcome? I'm leaning toward 'yes', but without a strong conviction about that leaning. When I listen to Dr. Chaffee, I'm ready to dive into carnivore. However, considering the enormous body of evidence Dr. Greger has amassed in his book, "How Not to Die", there's compelling evidence to suggest that plant-based eating also confers enormous benefits to many who follow it. And that leaves me firmly seated on the fence.

[@mfkleven]

Great points. And forgive me if I misrepresented the original post. You’re absolutely right: we should know by now if we’re herbivores, carnivores, or omnivores. That seems like such a fundamental question, yet the debates rage on, and the science is very confusing. The archeological record is clear that humans have always eaten whatever they could, plant and animal, carbs and fat. We are, in fact, omnivores. However, that doesn’t rule out the possibility that a more restrictive diet might be optimal, especially within a modern context. Plant-based diets have the most evidentiary support to date, but that could be simply because more studies have been done on veganism, and because it’s usually been compared with a standard American diet of ultra-processed food. Perhaps someday carnivores will have an equally abundant stack of studies on their side, but to date their evidence is almost entirely mechanistic and anecdotal. Animal consumption can increase cardiovascular disease through its effect on apo B-that’s pretty hard to dispute at this point. But it can be easily mitigated pharmacologically if needed. Interestingly, the common ground among competing dietary tribes is real food, which is basically the opposite of the standard American diet. Evidence against ultra-processed food is compelling, growing, evolutionarily sound and mechanistically plausible. Perhaps that ought to be our focus. I think Peter’s take on this subject is appropriate. When something really matters, the effect is unmistakable, and hazard ratios are large-like with smoking and lung cancer, or with VO2 max and mortality. When an effect is very difficult to tease out, it probably doesn’t matter all that much. The superiority of a plant-based diet is pretty consistent when compared with omnivorous or low carb diets, but hazard ratios are small, sometimes too small to detect. Furthermore, much of that benefit vanishes when studies control for fruit and vegetable intake. So, as Peter says, obsessing over dietary dogma is an example of majoring in the minors. A vegan who doesn’t exercise is also minoring in the majors. Focus on things that really matter, and what seems to matter most about diet is real food and energy balance. That’s my take for the moment, but my opinion will change as the science evolves!

I have 45+ years' experience in designing eco-communities, farms, landscapes, homesteads, ponds, pools, structures, greenhouses, small orchards, etc. This all started as I grew up studying Marine Biology and then at 17 found yoga, meditation, natural foods (which at that time meant making your own granola, growing your own wheatgrass, sprouts, etc.) and other healing modalities. Helped establish a healing retreat community in the PNW and lived there for years, honing in on the food growing and preservation methods. This evolved into doing this work professionally. Currently have a team for designing farms, eco-communities, retreats, etc. and that team includes 2 farmers, naturopathic doctor, 3 architectural draftsmen, 2 interior designers, and my own experience.....as well as a network of regenerative agriculture experts in livestock, marine, plant science, alternative energy, etc. If the focus is in building ( in many cases restorative re-building) soils (including with the ruminant animals doing their service) the result can be improving the ecology while producing more dense quality foods and increasing wildlife diversity as well.

Attia actually has tried to be TOO “evidence based” which is why he has had to change his position on most of those things - as a pharmacist, I knew that healthy people taking metformin was a poor choice, regardless of what the supposed evidence said. Because I balance evidence with some very basic principles about health and nutrition and life in general - one of which is a synthetic pill isn’t going to make a person healthy in the long term (a person that’s already probably in the top 5% of what we consider healthy) and there’s no way we know the downstream effects of a drug like metformin that has very profound effects at a cellular level. I also intuitively knew fasting that much wasn’t a good idea for someone at his level as well as GMO foods being a bad idea. I gained a ton on respect for him for being willing to pull himself away from those beliefs eventually, although it took a while, he did it and is open about it which is excellent.

Probably prolong fasting when you’re lean may consume under used muscle but for most of us with body fat and some excess loose skin (from weight loss), loss of muscle is probably not a concern. I lost 80 lbs doing keto and 3-5 days water fasting once a month and i still have lots of muscle strength. I could probably lose another 10-20 lbs (of fat and skin) before my body would need to resort to consuming my muscles.

Things that others in the fitness world have BEEN saying and never changed b/c the science is applied correctly. Dr. Attia is an extremist that applies that attitude to everything he does. You can hear it in his statements. He’s stern, this is the way it is, nothing outside the lines. Then when he burns out, he changes his mind, and makes light of what he just got finish promoting.

This is why I walk 2 miles/day, 6 days/week and grow my own Heirloom seed organic garden. Plus I eat cleanly - near zero sugar, no alcohol, no drugs, fish, eggs, nuts, triple filtered water, non-processed food 95% of the time, grass fed meats, etc. I fast once a year 21 days in January to cleanse myself of the previous year and for spiritual reasons - which I am currently doing to pray for Jerusalem, family, friends and the world. I work on keeping my mind and emotions in good order. Also, back to foods, I do not eat bad oils. I'm 66, female and not on any medications. Apart from the world falling apart and people behaving like animals, I enjoy my life and the truth of God's Word, The Holy Bible. I avoid sin at all costs, too.

fasting one day, or having a 36 hour water fast once a week, should be enough for most folks without reducing muscle mass. Couple with walking 10000 steps everyday and eating healthy foods and run a few times a week should be enough to stay healthy.

When i was a kid until i turn 20 i suffer from constipation all the time, my stomach used to burn and hurt. After i turn 20 i moved away from my parents and start cooking for myself. People say that without knowing i do fasting. I wake up and drink a cup of black coffee everyday without suggar and before i leave for work i eat a cup of yogurt. I Dont eat anything else until 6:00-7:00 ish that we have dinner. We like to go to the river after work and do some fishing on the paddle board and have an empty stomach some how give us more energy, i do cook almost everyday, and we dont follow any diets. We eat everything! And that works for us,people tells us all the time that we need to eat a bread or something in the morning but if i eat i get tired and lazy... this is been working for us , we both go to the bathroom everyday, we dont have any stomach pain like at least i used to have all the time.

Yessir… “Mental health” is the new buzzword. I can just use an extremely easy example of my wife who often times overthinks things and puts unnecessary stressors on her brain… a handful of days ago during a week day where we were busy she just felt like taking our daughter to the park even though it was kind of late and we still needed to give her a bath and what not. On the way home she was just raving about “that felt soooooo good and I really needed that.” “Mental health” is just simply unplugging from social media and all of this information overload and intentional raging that people above you want to control you… stop worrying about trying to “hack” everything and just enjoy life for what it is… which is just life and living. There’s no secrets.

Exercise and moderate fasting are the best way to detox and rejuvenate the body. Use these methods to optimize health, and should not mainly using for weight loss.

[@deusvlad2.083]

I did 4 years straight intermittent fasting with calorie deficit training 6-10 hours per day I kid you not, and I looked 20+ years younger. One meal per day about 2-4k calories depending on my goals. I was in pure ketosis I lived mostly on protein shakes x2 x3 sometimes, creatine supplement and BCAA with all 9 essential amino acids and electrolytes before during and after training, during the day and at night my one meal of the day between 2,000-3500 calories. I never gained weight, I didn't bulk because I did heavy cardio and weight training, I toned, leaned and gained strength and epic stamina of Atlas, instead of muscle mass. Just want to say if you achieve the 100% pure ketosis you become superman/supergirl. And I'm not talking about after 1 day, I'm talking about every fiber of my being run on ketones. I had to burn away all the carbs in my body spend days training and eating as healthy as I can, and after some months I started to achieve oneness. You can only achieve this state when your completely net 0 carbs and bodies fuel is explicitly fat/protein during training. restoring my glycogen via protein and living the best time of my life. Edit- As for what this guy on the left is saying, it's wrong, you don't lose muscle mass when your training while fasted, or rather he did it wrong, you should keep your amino update via BCAA not just that all 9 essential amino acids, and perhaps a low carb 0 net carbs protein shake for post training which is after. Also if you spike your insulin levels during training with carbs, you most likely won't stimulate the muscles to grow as muscle doesn't grow with insulin resistance, it blocks the growth hormones I believe. The only way you lose muscle in training while fasted is if you do too much cardio without taking aminos to protect your muscle from catabolic breakdown lol. That guy on the left simply trained wrong while fasted, and now he's talking about GMO's being missunderstood? lol oh hell no you did not just say GMO's are ok to eat lol. Hey there is research and data on glyphocate linked with cancer and here's a freebie in your ice creams like Ben and Jerry's that has ingredient called Carrageenan, and glyphocates, and I believe they raised this issue with Ben and Jerry's to which they replied they will cut down on the bad ingredients. Who knows if they will do that or when. Possible dangers and side effects of carrageenan There is some debate over whether the findings of animal- and cell-based studies can apply to people. If they can, the possible side effects of consuming carrageenan include: inflammation bloating irritable bowel syndrome and IBD glucose intolerance colon cancer food allergies

[@keefeweekers5739]

He is talking about 7 to 10 day fasts that cause muscle loss. I heard you begin to lose muscle about day 6 or 7 of a fast. Longest i did was 5 day fast and i didn't lose muscle, but it took a week or so for my glucose store to be filled again

[@deusvlad2.083]

@@keefeweekers5739 m8 any kind of fasting is amazing for the body, he lost muscle mass it's his own fault he didn't do it right. of course if you have no carbs, no fats and no proteins your body will start devouring the muscle during fasting and training. Growth hormone or not if you don't stop the breakdown of muscle cells you're going to lose it. I've done some mad research on fasting with amino acids, calorie deficit whilst keeping muscle cells it's epic my research was on my own body for 6 years, I would carry heavy weights on me while doing intense cardio training for 6 hours a day minimum sometimes upto 10. There the only time I lost muscle was when I didn't have any aminos or enough protein in the body, the protein restores glycogen and prevents catabolic breakdown of the muscle tissues, you don't need food while training, but you do need all 9 essential amino acids. Of course if your true fasting you shouldn't exercise that heavy, and you should always by end of the day have enough protein vs the amount of exercise you've done. and during exercise if you do cardio you will lose muscle mass unless supplementing protein/ aminos to stop your muscle from wasting away. Hope this helps dood. p.s What my body used to do is store any excess protein in the cells of my body and being smart it saved it until I needed it to restore glycogen as my sugar intake was nearly 0g per day, I think it was typically 12g of sugar from natural sources like blueberries and raspberries, aside from that I had proteins and fiber from salads and meat, depending on the calorie intake I would either bulk overnight or lean.

[@kaimikkelsen2014]

People don't realize how proteins and fats are important for the body Lots of complaints from keto newcomers that is keto not working for them but they don't realize about thing called keto adaptation Go for ketosis not just enough, it may take 3-6 month for body to start fully use benefits of keto Again if you use only lean protein and not combine it with healthy fats it wouldn't give you full strength Fasting and IF just for those who need achieve certains goals and not really necessary for health Almost everyone on keto goes for IF just because you lose your regular appetite and no needs to eat three meals a day I'm 16 months on keto and fixed my skin problem including psoriasis, dandruff, my skin look healthy and glowing and I'm look younger and healthy Keto reduced my body fat, blood sugar stable, signs of IR also gone

On National Geographic on Disney Plus there is a documentary series called “Limitless with Chris Hemsworth”. In episode 3 Peter Attia is seen as Chris’ advisor. They do a 4 day fast together. This series was produced in 2022. Peter is saying that he hasn’t done a prolonged fast since 2020. This is actually incorrect and I just wanted to make people aware of this inconsistency. I still love Peter though.

[@kristina6715]

[@lorinichols9996]

So he went from admittedly fasting too much to hardly fasting at all? That doesn’t really make sense in terms of his lever analogy (from his podcast). If pulling really hard on the lever isn’t working for you, you stop pulling that lever completely? Also during those three years, he was getting three years older, so could’ve lost some muscle mass due to that alone. Balance, nuance…?

[@mfkleven]

I think his “levers” approach applies to people who need to make changes, particularly weight loss. He was pulling the “time restriction” lever when he didn’t need to, and it cost him muscle, so he stopped.

@@Lovebomb-pu7ji Don't jump to conspiracy theories just because someone changes their mind, especially when you're misunderstanding what he's saying: 1) He's not promoting GMOs, he literally said he _used_ to be dismissive of anti-GMO sentiments, but has changed his mind to be more cautious of GMOs because the pesticides they're engineered to be resistant against are inevitably going to be on the vegetables, and _that's_ a problem. Maybe you jumped to conclusion because he wasn't promoting the "organic" label, but what he doesn't explain is "organic" doesn't actually mean "pesticide free" - the FDA has a list of approved chemicals that can be used as pesticides and still _legally_ be labeled "pesticide free". 2) He said he's not doing _excessive_ regular fasting (his routine was 7~10 day water fast every 3 months, and a 3 day water fast every month) anymore, but when Thomas brought up shorter fasting (which is at the start of the agriculture topic instead of the end of the fasting topic, for some weird editing reason) he was very quick to agree there's nothing wrong with a 24-hour fast.

What I find amazing is that he consider 10-12 hours weekly to be a "low" level of exercise 😂 I'd consider myself very fit as a recreational athlete only training 9 hours a week: 2 hours high-intensity kickboxing, 4.5 hours moderate-intensity MMA & taekwondo, 1 hour stretching weekly, as well as 15 minutes minutes of high intensity resistance training daily. I really don't think it takes that much time to build foundational strength. I started working out during lockdowns in 2020 and was only doing 10 minutes of high-intensity resistance training daily. I still built a 2.5x bodyweight deadlift and had decent cardio and flexibility. Just don't want anyone to hear this and freak out cuz they think they might not be doing enough.
