Dr. Chris Rhodes explains what fasting is actually doing in the body, where the benefits begin, and why shorter fasting windows may not deliver what many people expect. He walks us through the science behind fasting mimetics, including how his team studied a 36-hour fast and built a supplement around the molecules that arise during it. You come away with a clearer way to think about hunger control, food noise, metabolic health, and the tradeoffs between fasting, appetite-suppressing drugs, and everyday eating. He also offers a sharp take on saturated fat hype and makes the case for a more personal, evidence-based future in nutrition.

Key Moments
"What most people do not realize is that they are often not getting the benefits of fasting that they think that they are getting."
“From a biological perspective, it takes around 24 hours without food in order to actually activate that metabolic switch where you're going from, you know, fed metabolism, glucose metabolism, over into ketone metabolism and fasting metabolism.”
"Let's find patterns that work specifically for you."

Donnie Moss explains how she went from cardio-only routines to strength training at 55 and why she now pushes “move every day” as the baseline for feeling better. She shares a practical approach built around short, doable workouts that help midlife women rebuild consistency without making fitness an all-or-nothing identity. The conversation also gets real about menopause symptoms that can feel scary when nobody has named them, plus how mindset and self-talk can shape follow-through.

Say hi to the AGEIST team!

Filmmaker David Donnelly joins us to discuss his new documentary Forever Young, an exploration of the rapidly advancing science of longevity. What began as a skeptical investigation into whether the hype around anti-aging breakthroughs was real ultimately revealed a growing body of research focused on extending healthspan and preventing disease. We examine what the science supports today, from the role of prevention and lifestyle to emerging therapies now entering human trials. Along the way, David raises larger questions about purpose, social connection, and how society must adapt as people begin to live longer and healthier lives.

Key Moments
“The bigger idea is that the spine plays a critical role in how the body functions. When communication gets interrupted, the body can work less than optimally… sometimes with no pain at all.”
“The body isn’t fragmented. It’s more like a hologram—everything is connected to everything else. If one part has an issue, it can affect the whole.”
“Instead of only asking ‘what stops disease,’ ask: ‘what creates health?’ That’s salutogenesis—the creation of health.”
