All plants are toxic to varying degrees. I haven't changed my mind on that. But recently our oldest daughter came up with a business idea: – making salves from plantain leaves infused in beeswax and olive oil for their antiba...

Most people assume eight hours of uninterrupted sleep is the biological default. It isn't. For the vast majority of human history, people slept in two distinct phases — waking naturally in the middle of the night for prayer, ...

Most people think of a knee injury as a knee problem. You tear something, you rehab it, you move on. But the science tells a very different story — one where a single traumatic injury quietly drives cartilage degradation, car...

Most people assume they're eating well when they go out by choosing the "right" food categories: eggs instead of pancakes, salmon instead of a burger, salad instead of fries. But once food leaves your kitchen, categories matt...

Most nutrition debates revolve around the wrong questions: Should we eat vegetables or not? Grains or no grains? Animal-based or plant-based? But as I discuss in this episode, framing nutrition solely by food categories overl...

Every five years, the U.S. dietary guidelines get updated. Usually, that update triggers some mix of frustration, disbelief and déjà vu. This time was different… not because the guidelines suddenly got human nutrition right, ...

Most people assume they’re being proactive about their health because they get an annual physical and a standard blood panel. A few numbers come back “normal,” the doctor gives a thumbs-up, and that’s the end of the conversat...

The general consensus on sauna bathing is that it’s a powerful tool for longevity, recovery and metabolic health. More sessions, higher heat, longer durations — all of these strategies are commonly assumed to produce better o...

You can do everything right on paper — organic, grass-fed, pasture-raised, regenerative — and still end up eating the very compounds you were trying to avoid. That’s the blind spot I’m digging into in this episode: the ways f...

It’s been just over eight weeks since my meniscus surgery, and I wanted to share a transparent update on what’s been working, what hasn’t, and how my knee is performing now. In this episode, I walk you through the entire heal...

Most of us don’t realize how quickly the urge hits. You sit down at the DMV, nothing is happening yet, and your hand is already halfway to your pocket. Reaching for our phone has become so automatic that we barely notice it, ...

For years, my blood pressure readings at routine checkups came back higher than I expected, even though I train hard, sleep well, and pay close attention to recovery. I wasn’t hypertensive, but those numbers never matched how...

We’ve been using Eight Sleep at the Kummer house for years, and in many ways it’s been an incredible tool. The pod keeps the bed at exactly the right temperature through hot Georgia nights; lets us set different temperatures ...

Coffee can be both a tool and a toxin, depending on how it’s grown, prepared and used. In this episode, I take a closer look at caffeine and coffee through a practical lens — what science says, what I’ve experienced, and what...

A few days ago, Kathy asked me to listen to a parenting podcast by Dr. Becky that stopped me in my tracks. In it, the host told a story about planning a movie night as a kid — driving to Blockbuster, hoping the film you wante...

When Consumer Reports recently claimed that protein powders contain "high levels of lead," it sparked fear and confusion. In this episode, I break down what's actually going on, including how heavy metals end up in supplement...

Shop the Amazfit Balance 2 here: https://us.amazfit.com/ After nearly a decade of wearing an Apple Watch, I finally ditched it. Not because I stopped caring about health data, but because I realized the device was working aga...

Most conversations about the environment fall into polarized camps — either denial or panic. But living responsibly doesn’t have to be political or extreme. In this episode, I take a practical look at what stewardship can loo...

A few weeks ago, I found myself driving home late after a long day of hauling gear to our new property — hungry, tired, and joking with Kathy that if we were a “normal” family, we’d just pull into a McDonald’s drive-thru. Of ...

When most people think about blood pressure, they think about a once-a-year reading at a doctor’s office. But one measurement on one day doesn’t tell you much about your cardiovascular health. Just like a single fasting gluco...

Most people with gut issues get fed the same script: It’s genetic. It’s lifelong. The best you can do is try to manage the symptoms. But in this episode, holistic nutritionist and physician consultant Josh Dech pushes back on...

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...
