What to Eat & When to Eat for Longevity | Episode 2

What they calculated was the chance of dying based on various diets ... What they found was that what's called the 'hazard ratio' went down the more vegetarian and vegan you were. What does that mean? Your chance of dying goes down.

Eat less often. Those three words: eat less often. That's the one thing that will have the biggest impact on your longevity based on all the science we'll talk about today.

If you switch to a Mediterranean diet, if you're under 80 and you do that, you reduce your mortality, chances of death on any given day, by 31%.

There are certain body weights, waist to height ratios that are optimal for humans, about 0.5. But yeah, losing weight is helpful. We're not fat-shaming anybody, but we're going through the science ... It is true that if you're leaner, you will live longer. That is a fact.

There's also a molecule called TMA that is in meat that goes into the bloodstream. The liver turns it into a toxic molecule called TMAO. And this TMAO is shown, at least in animals, probably in people, to enhance/accelerate cardiovascular disease.

The most reliable way to extend lifespan of any animal or even a yeast cell is to restrict its calories.

What we know from many animal studies, even in yeast: If you downregulate the activity of this mTOR protein complex, you get longer life. Why? Because it's activating a process called autophagy, which recycles proteins.
