    129: How Humans Actually Slept!
    Feb 25 2026

    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, reflection, and quiet work before returning to sleep until dawn.

    In this episode, we explore what ancestral sleep patterns actually looked like, what the science says about biphasic and split sleep, and why your 3 AM wake-up might not be insomnia. We also break down ultradian rhythms, the overlooked biology behind your afternoon energy crash, and two practical sleep templates you can apply to a modern schedule.

    Your sleep doesn't need to be fixed. It might just need to be understood.

  • 128: Red Light Therapy Protocol for Knee Pain and Recovery with Forrest Smith CEO of Kineon

    128: Red Light Therapy Protocol for Knee Pain and Recovery with Forrest Smith CEO of Kineon
    Feb 18 2026
    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, cardiovascular impairment, and systemic inflammation for decades after the initial damage has "healed." I got a firsthand look at this when an MRI revealed two meniscus tears, a split MCL, and early-onset osteoarthritis in my left knee. That last one was humbling. I always assumed osteoarthritis happened to other people — older, less active people. Not someone who squats heavy and trains consistently. In this episode, Forrest Smith — CEO and Co-founder of Kineon Labs, a health technology company specializing in targeted red light and laser therapy devices — returns for his third appearance on the podcast. And the picture he paints of what happens inside an injured joint long after the rehab is over is sobering. For example, the NFL tracked over 3,500 players who'd returned to competition after knee injuries and found chronic inflammation still present 10 to 20 years later, despite world-class rehab. Notably, the quads on the players' injured side ran one to two degrees colder, a sign of impaired cardiovascular delivery. And the risk of major cardiovascular events jumped by 50% – not because of the original injury, but because of inflammation that never resolved. That's the cycle most people don't know they're stuck in. And it's where laser-based photobiomodulation changes the equation. Targeted 808nm lasers can drop inflammatory markers like TNF-alpha and IL-6 by 70 to 85% within days. Once that chronic degradation slows down, chondroblasts — the fast-growing front end of cartilage — can actually proliferate and begin rebuilding the extracellular matrix. Slow the destruction on one side, accelerate the biology on the other. That's what "regrowing cartilage" actually means. Penetration depth is what makes lasers fundamentally different from LEDs. At five to seven centimeters of reach, you're dosing 10 to 100 times more tissue volume than a surface-level panel can touch. Then there's the other side of this that almost nobody talks about: the ibuprofen your doctor hands you after surgery. Research shows that 90 days of use increases heart attack risk by 48%, heart failure by 35%, and major coronary events by 75% — while actively impairing the collagen and fibroblast function your body needs to heal. It's doing the exact opposite of what most people assume. If you've ever dealt with a joint injury, chronic inflammation, or just assumed over-the-counter painkillers were harmless, this one's worth your time. About Forrest Smith: Co-Founder and CEO of Kineon, a health-tech leader who spent 18 years in China building hardware startups and mastering the local supply chain. A lifelong athlete and CrossFit enthusiast, he founded Kineon after developing a portable, medical-grade laser device to treat his own chronic knee pain.

  • 127: Why "Healthy" Restaurant Meals Quietly Backfire

    127: Why "Healthy" Restaurant Meals Quietly Backfire
    Feb 11 2026
    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 matter far less than sourcing, fats and preparation. Restaurants are optimized for speed, consistency and profit. That usually means seed oils are used for cooking, sauces and dressings; that produce isn't organic; that poultry is low quality; and that most seafood is farmed. In other words, even meals that seem responsible on paper are often cooked in oxidized fats and paired with ingredients that quietly drive inflammation. In this episode, I explain why those hidden variables matter more than what's listed on the menu — and why even well-intentioned choices can work against you when food is prepared in an environment that was never designed to support your health. The real issue isn't an occasional meal out. It's how these small exposures compound over time. You don't feel it after one dinner — you feel it after years. And by then, most people blame the wrong things: carbs, protein, or entire food groups, when the real problem was never what they were eating but how it was being prepared. So what can you actually do about it? The most effective solution isn't exciting: when you know you'll be away from home, bring food with you. A lunchbox with leftover meat, eggs, fruit and simple whole foods beats a restaurant salad almost every time — and travels far better than most people expect. When eating out is unavoidable, the goal is to choose foods that are harder to mess up: plain red meat, simply cooked eggs, burger patties without sauces, and meals prepared with butter or olive oil when available. Ironically, foods with a "health halo" — salads, grain bowls, plant-heavy dishes — often perform the worst once dressings and industrial oils become involved. This isn't about fear or perfection. It's about being realistic. You can't outsource your health to systems that were never designed for it. Cooking at home and controlling how your food is prepared remains the most reliable way to protect your long-term health.
