I recently spent a week in Austria, bouncing between my grandparents’ farmhouse and the alpine trails I grew up on. And it hit me how stark the contrast is between the foundation they built and the environment kids are growin...

Most people have been told at some point that the way to “detox” is to buy a cleanse, live on juice for a week, or chase down some supplement that promises to pull toxins out of the body. But the reality is very different. In...

In this episode, I share a fascinating 1950s endurance experiment with rats that uncovered what researchers called an “anti-fatigue factor” in beef liver. The results highlight why organ meats like liver are nature’s ultimate...

For years I thrived on two large meals a day – a late-morning breakfast after training and an early dinner. And the results spoke for themselves: stable blood sugar, excellent insulin sensitivity, low body fat, and plenty of ...

Ten years ago, our bathroom shelves were packed with scented candles, colorful shampoos, and convenience-store deodorants. They smelled fresh and felt clean — but eventually we learned what those synthetic fragrances and long...

In this episode, Kathy and I unpack how we reduced our exposure to environmental toxins—from improving tap water safety and installing water filtration systems, to replacing plastic containers and upgrading to non-toxic cookw...

When most people think about saving the planet, they picture cutting back on meat and eating more plants. But what if the story we’ve been told about how plant-based diets equate to sustainability is missing half the truth (a...

For most of human history, survival depended on eating the foods that gave us the most nutrients with the least effort. That usually meant animals, which are dense in protein, fat, and bioavailable vitamins and minerals. But ...

It’s easy to assume that food affects everyone the same way. But when my wife Kathy and I wore continuous glucose monitors for two weeks, we learned just how different our responses actually are. For example, a bowl of curry ...

Biohacking wasn’t always about gadgets. It used to be about building a better lifestyle by fixing root causes with movement, light, food and sleep. But somewhere along the way, optimization gave way to outsourcing. Today, it’...

​​In this episode, I break down exactly what I do before a CrossFit workout. No powders, no hype—just the simple stuff that works. Hydration, black coffee, a walk with the dog, some sunlight, and a cold plunge to boost perfor...

Someone recently told me about a Mayo Clinic researcher who claimed that cold plunging triggers the same chemical response in the body as dying — and that, basically, you die a little every time you do it. I couldn’t believe ...

In my widely-read article about how I cured my IBS symptoms, I recommended against eating eggs in the early stages of gut healing. And I got plenty of pushback for that recommendation. I understand why. Eggs are hailed as nat...

For decades, beef has been painted as the villain on our plates, blamed for heart disease, cancer, climate change, obesity, and even poor digestion. But have you ever stopped to question if these claims are backed by solid sc...

As a former pro triathlete, Brad Kearns used to push himself to the extremes of human endurance. He competed globally, chasing medals and personal records, only to eventually confront a humbling truth: his intense cardio regi...
