Best Selling Author: This Diet Will Betray You!

Is the longevity supplement hype real - or are you wasting money? Bestselling author Bas Kast breaks down what actually works in nutrition, supplements, and slow aging.Most people don't suffer from a lack of health advice. They suffer from too much of it. One expert says eat more protein, the next says cut animal foods. One says supplements are useless, the next sells a 100-pill longevity stack - and all of it sounds convincing.In this episode of Return on Health, hosts Niko Hems and Miguel Medina sit down with Bas Kast - the science author whose book The Diet Compass (Der Ernährungskompass) sold over 1 million copies - to separate evidence from noise. We cover what still holds up in nutrition science, which supplements are worth taking (and which are pure marketing), why you are never the "average" person in a study, and Bas's new project SlowAger.━━━━━━━━━━━━━━━👤 ABOUT THE GUEST━━━━━━━━━━━━━━━Bas Kast is a science journalist and bestselling author known for translating complex nutrition and longevity research for a general audience - without academic jargon or wellness hype.
