What is the minimum protein we need when we are not trying to gain more muscle mass? I know we can go all day with zero protein but do we have to eat twice as much to make up for deficient days? How long can we go on say 1/2 of the recommended average minimum. What would happen if I had only 60g of protein a day for 15 days and my lean body mass was around 150 lbs and/or my healthy BMI of 20 was 152 lbs

Good stuff 👏 👍

Thanks.Thanks.🇨🇦

Fascinating. Love the data based approach Dr Levine takes

Great episode with two outstanding scientists with training from the Dave Costill Human Performance Laboratory!

Interesting facts about Jim Fix’s death

I like how you bring different opinions on the podcast to give us a nuanced picture of the current science.

The questions in this podcast were poor and came from a lack of understanding about what the constrained model of energy expenditure hypothesis is actually saying.

Dan Buettner, the Blue Zones guy, has been trying a systems approach in the US.

I've just read Johan Hari's Magic Pill. My comment is the same as him in his final chapter, Japan! A wealthy democracy with far less problem with obesity than the anglophone countries.

Interesting but the one thing he doesn't marry with exercise is nutrition, which is equally important. That would be an incredible video, to see how these issues interact.

Two smart guys trying to understand the overcomplicated world of physical activities. Seems they forgot about sleeping habits, massage, stress-free life .... I enjoyed listening!

Steroids

Fantastic

I wonder if he considered the Stryd foot pod and their RSS (Running Stress Score) as a means of measuring ones load.

A bit murky and vague in parts but, overall, a useful discussion with honest, common-sense opinions and some very pertinent truths to be considered by regular, committed and too often over-enthusiastic runners. ......What the heart often wants, the body can not deliver! Cheers.

Thank you Dr Barnes. Thank you Dr McConnel. Another great discussion.

Dr McConell. Excellent discussion. I want to recommend someone on youtube I know you will like. His name is Mario Kratz. He holds a PhD and specializes in diabetes, I think. His channel is Nourished by Science. He's a carb guy. He discusses how to eat carbs and how to use and avoid using CGMs, and much more. BTW, I hope you are running now! I just saw your chat with Dr Davis. She is amazing! I wish she were my coach 15 years ago. I also have a chronically sore left calf. And a weak right hip. So many mistakes. So much I didn't know. So much I will never know. She had it right: keep young people out of the cushy high-heeled running shoes.

Dr McConnel. I swear I wrote my first entry right after your intro. Anyway. I am only now discovering you bought the Xeros. I am glad to see you have hope.

Dr Davis knows how to promote lasting behavior-pattern change.

Thanks!

Interval running.

Tulip poplar bark or cork inner soles, flat, and a decent canvas upper, thin natural rubber outer soles. My dream shoes.

Really important show. The Xero shoes are good. Midsole strike. It requires lots practice for good form for soft landings. I didn't take it seriously enough anyway: bad diet. I had spill on a kickbike a few years back and pretty sure I got a concussion, back of head. So it's walking and cycling now. Oh, and I got super pair of shoes way back around 2012 by Brooks called Green Silence. What turned me toward all of it was someone who promoted Huraches: Christopher McDougal, on NPR, website, etc, around 2009. Thanks again Dr McConell.

Training with power turned me into a much better cyclist at 42 than I was at 24. Andy's insights were instrumental in my embracing of Sweet Spot training, which is doable for someone with a full-time job.

The online interviews with Inigo San Milan explain everything! The top exercise scientist, who has spearheaded zone two.

Gregoire is very knowledgeable and passionate about the topic. You can tell he has certainly done his research and experiments.

53:07 Again this lady goes on about glycaemic impact of fruit is smaller then if you eat starchy carbs. This is false and misleading information because CGM/glucose monitors can not pick up fructose and therefore can not inform on the damage to your liver of fruit. Since the unscientific nonsense of 5 a day NAFLD has increased, 5 a day is marketing gimmick in order sell more fruit and veg not based on any science and the liver needs time away from fruit and sugar to deplete the stored fructose in the liver. Carbs had a season once and our bodies are not use to eating them all year around.

I'm type one the only way to control my blood sugars is low carb/mostly carnivore. But I cringe when people who don't know what it like to have the problems of someone who been type one for 28 years and tries to say you are depriving yourself, like the lady says 'cutting out all the foods you like'. Well I would like to correct her and re-frame that as 'all the food you are addicted to' around 44:50. For me the bottom line is you either limit your diet or limit your life by going blind or having your feet cut off. There is no way to having your cake and eating it as far as I can see, and being able to see is more rewarding then pigging out on processed crap. By our very nature eating carbs inspires gluttony, and trust me it not a good look either and can lead to mental illness especially if you avoid animal fat.

looking forward to watching this one!!

As a 52yo runner, today's technology has allowed me to run more mileage, race faster and remain injury free. The over 50 runner that can wear minimalist shoes without injury is very rare.

I just re-listened to this. It's fine, and Coggan and McConnell are real experts. And I learned things from it, no doubt. But the whole hour and half discussion doesn't have a point unless it argues with a vague, ridiculous straw man argument like "is it true that rigid adherence to zone 2 is the only way to train regardless of your goals?" For instance, listen to the section on "what is Zone 2", Andy just rambles for a while. It's good stuff but he doesn't answer the question. Then he wanders off into a discussion about performance metrics, which is very insightful and helpful, but off topic. And that continues for the entire episode. You could listen to the Ben Levine podcast where Dr. Levine recommends a two to three workouts a week in Zone 2 in his "exercise prescription for life.". His definition of the recommended effort for those workouts is the same as San Millan's definition of Zone 2.

Just finished listening. Going to listen again. I barefoot walk indoors on a wood floor, 6-8 k steps per day. It's too uncomfortable to walk outdoors in shoes, even in minimalist shoes. I don't know why. Maybe something to do with being 70, ankle issues, and shoes.

“At least live well until your time comes!”👍👍

There is a specific lactate threshold for each running distance.

I think it’s a highly debated topic and you’ve already mentioned that you’ll interview people with other opinions. This shows that science isn’t black and white and all depends on context and population. For me myself, I recognised big improvement in hip stability and pain with improving my feet strength. I walk a lot with minimal footwear and run with shoes with a natural wide shoe box.

This seems like a departure from the usual science-based podcast to opinion-based. To adjust to minimalist footwear I would recommend reading about the collagen-building experiments by Keith Baar. A lot of elite runners train on dirt roads, and at longer distances like marathon they tend to heel strike.

Taste of blood…..

Thanks for another great podcast! Dr. Candow mentions another podcast at 56:45; Linda Raves? Wimda? Can you let us know the podcast name?

The argument from incredulity seems to be the focus of this video. It would be more persuasive if the focus were on the evidence. Should the evidence be better? Absolutely, but if we want to find out what actually works best, we need to produce higher quality evidence. That is true of any intervention. If the problem is 'How do we come up with a public health intervention that WORKS?' The answer is not going to be ANY single solution. We need something that people will do. If people use HIIT, but gradually decrease their intensity, that may indicate a lot of hypotheses to study. That does not mean that HIIT does not have any place in public health. If people who do NOT use HIIT gradually increase their intensity, that also may indicate a lot of hypotheses to study. Does that mean that non-HIIT exercise does not have any place in public health? Of course not. Perhaps the most important point made in the promotion of HIIT is that people who have DOE (Dyspnea On Exertion) are engaging in HIIT whenever they move. We need to figure out the best ways (plural) to address this, because with our decreasing fitness, there will be many more people with DOE due to heart failure and other chronic conditions. Why are the sickest people - the ones least able to recover - engaging in some of the most intense exercise as part of their activities of daily living and what can we do to help them and what can we do to help others avoid the same condition? .

So when you go very low carb, you are less able to controle bloodsugar when eating carbs. But what about bloodsugar made by the liver. Is it likewise more difficult to take up by the cells. Will your fasting bloodglucose go up as a result? If so, does your fasting insulin also go up as well?

I absolutely love your podcast and I have learned a lot from it. I agree with you that most people don’t need any supplements and I am always very skeptical of them. However I think it is worth mentioning cases where supplements are useful and indeed important for one’s health. For example I can never have normal iron levels without supplementing. I have tried many times and I always end up deficient. I have a very healthy, mostly plant based, diet but in this case it is not enough. Vitamin D is also another supplement necessary for half the year if you live in central or Northern Europe and cannot get enough sunlight exposure. Vitamin B12 is another one that seems to be causing me issues in athletic performance. I would love it if you could have a chat about that particular one. From what I have seen lower levels of B12, within the normal range, cause significant drop in performance and supplementation reverses it completely. If you ever have an expert on such matters I would love to hear their thoughts.

I have a great belief in Dr. Martin. Beyond being, smart, knowledgeable, creative, and innovative thinker, he is also an amazing human being!

A professor who can't pronounce etcetera is somewhat concerning.

really??? to maintain the same wattage for an hour or so during training doesn't make sense because "we don't ride bikes like that". I hop I misunderstood that comment because it is pretty dumb

This channel is an absolute goldmine - thanks for all the effort & content.

I love your work! Congrats! I would be amazing working with you in the field of research!

I have a heart transplant and I am 13 yeas post now. It’s so cool you were able to interview these guys. My fitness routine is running marathons. I haven’t done an IM yet for lack of training time and resources (wife and 3 kids) I recently completed the Los Angeles Marathon in 4:24:00 this past weekend. My VO2 max is around 50 according to Garmin, although I have never had issues officially measured in a lab. From a fitness perspective these are the guys that I look up to. Awesome interview! 🙂

laughable! sorry! I like a lot how science testing is actually lost on good gut health. Schadenfreude on my part. Probiotics and fermentable fibers! ha ha ha

great insights
