315: Scientist P.D. Mangan On Using Diet & Exercise To Fight Aging

Resistance training is a very important thing for everyone to do—whether they're a man or woman, young or old. We lose muscle as we age, and this is a really underappreciated fact. It's even detectable when someone is in their thirties. This accelerates over the years, and by the time someone is 80-years-old, they may have lost half the muscle mass they had when they were young if they don't do something about it—and of course, most people aren't doing anything about it.

There were doctors in the 19th century that said that if you want to lose weight stop exercising and if you want to gain weight, exercise

If you can postpone aging, you postpone all the diseases of aging. It's not about more years in a nursing home; it's about extending years of healthy lifespan.

The more muscle and less body fat you have—within limits of course, but speaking very generally—the healthier you are.

For optimal metabolic health, your waist size should be one-half or less of your height.

Caloric restriction has turned out to be the most robust and reproducible life extension intervention that scientists have found.

Intermittent fasting appears to be just as effective as caloric restriction for life extension.

There was a recent study that showed 88% of American adults had some kind of metabolic dysfunction and only 12% were clinically metabolically healthy.

In the United States, approximately 60% of calories in the average diet come from ultra-processed foods.

Chronic diseases might be better termed as diseases of processed food.

There's a phenomenon called 'normal weight obesity.' These people have a very high level of body fat even though they're a normal weight. They have the exact same health risks as somebody who's obese.
