On Today’s Episode:
What damage is the American diet doing to millions of people who have mindlessly bought into the misinformation about fats, “healthy” processed foods, and three square meals. For years we’ve looked at diets all wrong, and as research and technology is making more advances we can finally start to assess our individual risks for longevity and what the path to a longer healthier life is on a personal level.
Peter Attia is the co-founder and Chief Medical Officer of the popular fasting app, you probably have downloaded right now, Zero, and the bestselling author, podcast host, and longevity health expert. His latest book, Outlive, debunks many of the ideas you may have sworn by around diet and its ability to optimize your lifespan.
What we’re getting wrong about longevity?
– Diet isn’t the cure-all it was presented to be
– Someone with an obese BMI can be metabolically fit
– A lean person who’s metabolically unhealthy has worst outcomes
Peter is exposing common misbeliefs around longevity with his groundbreaking manifesto.This episode is a chance to expand your knowledge and distinguish the differences between lifespan and health-span.
Check out Peter Attia’s latest book, Outlive, The Science and Art of Longevity: https://www.amazon.com/Outlive-Longevity-Peter-Attia-MD/dp/0593236599
QUOTES:
“If you consider the difference between a person that doesn’t have type 2 diabetes and someone who does, it’s literally only the difference of one teaspoon of sugar in the blood.”
“High cardio-respiratory fitness and high muscle mass and strength are more predictive of a long life than anything else we know.”
“What good is it to have a brain that works if your body actually does not.”
“Living longer is not accomplished by living longer with disease. Living longer is accomplished by living longer without disease.”
“True prevention needs a set of tools that medicine 2.0 doesn’t participate in. Medicine 2.0, which is the medical system that everyone of us who’s trained goes through, is largely a pharmacologic playbook.”

all stress ages you. exercise isn't normal stress. it is extreme stress by definition. movement is healthy yard work, chores, and walking. this is what humans are meant to do.

My question is did Peter Attia have any bloodwork done as a teenager??? Because my guess is that drinking 2 liters of orange juice a day is overdosing on liquid sugar. My bet is that if there was anybloodwork done he would be prediabetic and have elevated ALT and fatty liver xue to the overdose of fructose. My understanding is that as he got older he gained weight and was insulin resistant.

What's working against American's longevity is our corrupted food supply! There are countries in Europe where their populations DO live a lot longer than ours in general! So, while diet may not matter in America, it's night and day between America and actual functioning countries where their populations and governments aren't morons!

I own his book and like it, but I find what he is saying here outrageous. DIET MATTERS profoundly in longevity bc of inflammation that a crap diet causes.

Most people who died from heart attacks do so because of dietary choices, not because of a lack of exercise. Diet can have a bigger impact on lifespan than excercise!

I’m in love with the non fat, Face Greek yogurt at Walmart, Whole Foods, Albertsons. About $6.50. 32oz 90 grams of protein, 25 grams sugar/carbs. Problem is I eat the whole thing in the AM with berries. But, I’ve gotten better at not doing that.

I don't want to live longer. I just want to have energy and be free of pain! So a proper diet will not make any difference then? OK got it. I can go back to eating Donuts!

I visit my grandfater 2 days ago – he is 95 years old – still keep going – never exercise, never eat avokado, never eat salmon or all of this superfoods… sorry for my english.
@bshalaby

Dr. Attias information is very encompassing and mostly accurate, but the 40 gms in one sitting of protein maximum has been debunked recently and evidently therre is no upper limit.

OK, he should know better than this. Absolutely you eat healthy you know live long life. I mean there’s a little factors here and there that can change things it’s like saying OK exercise eat Twinkies and you’re gonna live forever. Look at the blue zones. People don’t lift weights if you want to call it exercise they keep moving, and they eat well healthy
@PerryP649
October 31, 2025 at 3:23 am
attia does NOT reflect the opinion of Dr Michael Greger. VERY different theories on longevity. especially as it relates to protein intake. IMO, both are pretty extreme in their beliefs.

Garmin-watches gives a nice enough indication of your VO2-max, beside that you can perform variants of the "Cooper"-test, like max speed for 3 km, + puls at the end, etc.

Definitely some good information here, but saying dementia is anything other than insulin resistance of the brain is ridiculous. Dementia is Type 3 diabetes. Get rid of carbs and the brain can use fat for fuel. As a person ages, they become less efficient at burning glucose for fuel. Give the brain what it needs. Peter takes an antibiotic b/c he feels that it might help him in his cholesterol lowering journey? Dear Lord. Maybe if he didn't eat processed garbage, take so many drugs, and practice fasting to keep his insulin down, he wouldn't have these health problems in the first place.

From experience, if you want to increase your testosterone go carnivore and lift weights – stay away from carbohydrates and processed food

Im sure I've heard Dr Attia say that Keto is a great fit for him, but it's the practicality of adhering to it that was his biggest problem, especially now he has kids.
@Healthnut999
October 31, 2025 at 3:23 am
He's full of sht so why are the blue zone people so long lived? There are multiple factors and diet is very much part of that, I reversed so many issues on a primarily whole food plant based diet plus I'm 48 and look 30. He is highly misinformed.

I never watch these 2-hour videos. If you can't give the answer to the title in 4 minutes or less, it's not worth my time. The death rate is 100%, and I don't want to waste 2 hours on talking heads.
@peterazlac1739
October 31, 2025 at 3:23 am
It is an interesting conversation but I think he has it the wrong way around. We should look at ourselves as servants of our microbiome and the major part of our DNA that comes from the microbes past and present that have ben involved in our development and which play the major role in immune response and inflammation as well as brain function . They influence what we eat to optimize their survival and so keep us alive via epigenetics as long as we do that effectively. Rather than talk about exercise as it is now understood in terms of aerobic such as HIIT and strength via weight training or equivalent we should think of movement, originally to gather the food the microbes wanted and later with farming to grow it. I consider the interpretation of Blue Zones to be wrong for this reason. What is specific about the Blue Zones is the diversity of the gut microbes in the inhabitants and the link they have to local sources of food plus the movement and muscle strength required to gather or grow them which varies widely between groups.

Peter Attia is right. Diet is an epic fail. Ask 10 different "experts" what the ideal diet for Human health is, and you'll get 10 different answers. The TRUTH is that Humans are omnivores. The fact that people can survive on all sorts of diets is proof of that. A cow, for instance, would experience severe disease and organ damage if it ate meat. A lion cannot even digest the starchs due to a lack of amylase, or even taste sweet.
But this is not what people want to hear. They want to hear that there is this one diet out there that will give them cocaine-like levels of energy, heal their body aches, and end their mental fog. The problem is that there is no evidence that such diet exists. So they go from "Paleo" to "Keto", to "Mediterranean", to plant-based, etc, and are disapointed every time. They assume that, if they find the "natural" diet of humans, they willl achieve superb helath. This is the "paradise lost" fallacy, that postulates suffering as the result of moral sin, and that if you correct yos moral choices, you can achieve happiness.
The fact is that Evolution doesn't care one bit about you being very hery healthy or living a lot. Evolution is ok you with you just being healthy enough to reproduce. And even then, it cares only until you are 25 or so. After that, you are as good dead as alive. For instance, Huntington's Disease exists in the population because the expansion of "TAGA" repeats in the HTT geen that causes Huntington's makes women more fertile. The fact that it will destroy the woman's brain at age 50 is 100% irrelevant for Evolution because by that age she already had her kids. So she can just die. Likewise, Evolution never bothered fine-tuning the body to a specific diet that if you wat you make you fee amazing because calories in nature are scarce so you can't be too picky, and as long as you breed, that is that matter. People need to stop this stupid thinking that there is some magicsl "natural" way of eating that will make your body aches, your mental fog and your exhaustion go away. Maybe the reaso why you feel this way is because you body is shit, and you have shitty genetics.
The ony advice that I can give people when it comes to diet is to tonker with carbs, protein and fats while taking notes of how you feel and look until you find the right balance for you. But don't expect a "magic" diet that will givbe you cocaine-like levels of well-being. A diet is just a way to provide metablic energy and nutrients for the body.It's not a methamphetamine high.

Thank you Dr Attia for the brief comment of the FDA being on the verge of corruption. I’ve been an inpatient cardiac nurse for 27 years. I’m always researching learning and trying to make sense of certain things on my own related to medications and how I see them dangerously over used. The things I see with certain drugs that come and go and the kind of income the drug reps make is astoundingly high. I do not trust drug companies, the food industry, and the FDA. The amount of poisons the FDA still allows here in our food, and our cosmetics is so dangerous.

I am still watching the "mercials" before the video begins (as my little nephew calls them). I predict that the reason diet won't increase your lifespan is because diet can only help you LIVE your lifespan, not increase it.

As far as their saturated fat/cholesterol conversation goes…….isn't there an easier way to see if you have any issue? Like ounces of meat ones eats or something like that? TY.

So how do you tell if you have too much visceral fat? If you're a slim person, how do you tell if you're unhealthy. If you're heavy, how do you tell if you're a healthy heavy? Can you know without taking a Dexa scan? This is for the 17:50 min area of this video. TY!
