Dr. Paul Kolodzik spent 25 years in emergency medicine watching the long-term consequences of preventable disease. Now, he’s helping patients reverse metabolic syndrome using continuous glucose monitors (CGMs), low-carb nutrition, and strength training. In this episode, Dr. Kolodzik explains why blood sugar spikes—not cholesterol—may be the most urgent threat to long-term health. You’ll also hear why he believes wearables and strategic use of GLP-1 medications can radically change your health trajectory.

Teemu Arina, author of Biohacker's Handbook and one of the movement’s pioneers, believes biohacking may have lost its way. In this episode, he lays out a different approach to longevity. He argues that extreme health routines often do more harm than good, and that true well-being comes from adaptability, not rigid optimization. Teemu also shares why AI-driven personal health plans could replace cookie-cutter protocols, and how we can rethink aging as a balance between discipline and enjoying life. If you’re tired of endless supplement stacks and prescriptive morning routines, this conversation offers a fresh perspective on what actually works.

Are the everyday products in our homes quietly harming us?

Key Moments
Microplastics are everywhere and nowhere—because we can’t see them, we ignore them, but they’re in every organ of our bodies.

You don’t have to overhaul your life overnight, but small changes—like swapping out your tea bags or filtering your water—can add up to big health improvements.

We think more stuff equals a better life, but the reality is, simplifying what we own and use can dramatically improve our well-being.
