Rapamycin, NAD & the Truth About Slowing Aging | Matt Kaeberlein (opens the original)
Read excerpt
What if the most promising drug for slowing aging already exists.. but we still do not know whether healthy humans should take it? Dr. Matt Kaeberlein is one of the leading scientists studying the biology of aging. His work has focused on mTOR, rapamycin, cellular aging and the mechanisms that may allow us to extend healthy lifespan. In this episode of Return on Health, hosts Niko Hems and Miguel Medina challenge Matt on how far longevity science has actually come. They discuss what aging really
Everything You Know About Calories Is Wrong | Dr. Robert Lustig (opens the original)
Read excerpt
What if one of the most basic ideas in nutrition — that a calorie is a calorie — is the wrong way to think about metabolic health? For decades, Robert Lustig has argued that obesity, diabetes and other chronic metabolic diseases cannot be understood through energy balance alone. His central argument: what happens to food after we eat it matters, and added sugar — particularly fructose — can disrupt metabolic function in ways calorie counting fails to capture. In this episode of Return on Health,

Read excerpt

What if one of the most popular ideas about cancer is simply wrong? For years, social media has promoted the idea that cancer is primarily a metabolic disease - one that can be starved, hacked, or even reversed through diet. But cancer geneticist Dr Moritz Przybilla argues that decades of genomic research tell a very different story. In this episode of Return on Health, hosts Niko Hems and Miguel Medina explore why cancer is fundamentally a disease of DNA, why aging remains its greatest risk fac
You Can't Stop Aging! Here's What Actually Matters… | Prof. Suresh Rattan (opens the original)
Read excerpt
Most people think aging is a disease. Professor Suresh Rattan thinks that's one of the biggest misconceptions in modern medicine. The anti-aging industry has never been bigger. Every week there's a new supplement, a new biomarker, a new longevity protocol, or another promise that you can slow, reverse, or even cure aging. But after more than 40 years studying the biology of aging, Suresh has reached a very different conclusion. Aging isn't something to cure. It's something to understand. In this
