Boundless Life

Full Shownotes: BenGreenfieldLife.com/bluelighttruth In this episode, Matt Maruca, CEO and co-founder of Ra Optics, dives deep into the science and practical realities of blue light, circadian health, and optimizing your environment for better sleep and longevity. We tackle the nuances of blue light exposure from sunlight versus artificial sources, break down how proper blue light-blocking glasses can support melatonin production and overall wellness, and bust common myths—including those from recent documentaries and reviews. Along the way, Matt shares updates on the latest lens technology, why not all blue blockers are created equal, and the future of lighting and color therapy for health. Matt Maruca is the founder & CEO of Ra Optics, the leader in premium blue light protection eyewear. Matt founded Ra Optics after a decade-long journey to improve his own chronic health issues as a child and teenager. As he looked further, he came across the science of mitochondria, circadian rhythms, and how light influences these factors—playing an essential, but overlooked, role in our health and well-being. He became fascinated by entrepreneurship, and decided that he could use the in-formation that helped him to help others. Matt also created The Light Diet, a diet that directly addresses the root of the modern, chronic disease epidemic and mitochondrial dysfunction. Matt now spends his time traveling the world, studying and teaching about the relevance of light in human health cycles with a focus on reversing this situation, as well as integrating science with ancient Eastern wisdom.

Why Comfort is Slowly Killing You—And the Ancient Mismatch Making You Sick How modern life has turned us into zoo animals—and the simple stress strategy our ancestors used to stay strong, lean, and disease-free. Over the past five weeks, I’ve given you my perspective on the biohacking and longevity scene. I’ve noted the emptiness and time-wasting that can result from the vain pursuit of immortality so often seen in the “advanced” health optimization world (if you missed any of my articles, you can read them here). Episode Summary In this episode, I dive into why chasing biohacking gadgets and anti-aging protocols misses the bigger picture: we're living in an environment our biology was never designed for. I'll reveal the concept of "ancestral mismatch"—how our caveman bodies struggle in our temperature-controlled, food-abundant, movement-starved modern world—and show you how strategic doses of discomfort (hormetic stress) can reverse chronic disease. This isn't about becoming a caveman; it's about getting the basics right that actually move the needle. Question of the Day 🗣️ Which ancestral mismatch hits you hardest—too much comfort, too much food availability, or too little movement? And what's ONE hormetic stressor you could add to your day starting tomorrow? Key Takeaways Timestamps 00:00 – Introduction: Is biohacking a waste of time? 00:49 – The truth about stem cells, peptides & anti-aging modalities 01:47 – What is the ancestral mismatch? 03:06 – Why we can't go back (and shouldn't want to) 04:29 – The hormesis principle I live by: small stress = big resilience 05:23 – Exercise damage builds muscle (in the right dose) 05:50 – Sauna reduces all-cause mortality 06:06 – Plant toxins (gluten, lectins, saponins) make you stronger 06:38 – Fasting for 12–16 hours vs. extended deprivation 07:16 – My daily hormesis checklist (lift, sweat, cold, plants, sunlight) 07:54 – Next episode preview: I'll show you how to build your own home "blue zone" Connect & CTA 🎯 👉 Get these thoughts delivered to your inbox every week—subscribe at BenGreenfieldLife.com/newsletter and join the conversation with your comments and questions.

Full Show Notes: https://bengreenfieldlife.com/article/newsletter-1 Writing a book is a lot like childbirth—exhausting, and not something you rush back into the moment it’s over. I’ve never given birth, but I have written several books—and after finishing Boundless, I wasn’t too eager to jump straight into that process again. Until recently. There are just too many health myths wasting your time, energy, and attention—especially around supplements, cold and heat exposure, sleep, fasting, seed oils, red meat, carbohydrates, psychedelics, biohacking, and the modern obsession with living forever. So over the coming months, I’m going to tackle these types of topics through a weekly newsletter, article, and video series, which will eventually be crafted into my next book. If something resonates, let me know. If something falls flat, tell me. And if there’s a topic that deserves a deeper dive, point me there. Head to https://bengreenfieldlife.com/article/newsletter-1/ for today’s article, and drop any other feedback in the comments, including topics you think I should address in the book!

Full Show Notes: https://bengreenfieldlife.com/dylan/ In today's episode, Dylan and I explore how your genetics, microbiome, lifestyle, and activity level all play a role in what works best for you. I share my thoughts on carbs (they’re not the enemy!), why the Mediterranean diet is often a solid fallback, and how to customize your approach—whether you’re training like an athlete or just trying to eat well on a budget. We also get real about fasting: I break down what works for high performers, how to balance longevity with peak performance, and what fasting windows actually make sense if you’re pushing your body hard. From there, we dissect the critical topic of heart health, talking through the difference between stable and unstable plaque, key diagnostic tools, and both natural and pharmaceutical strategies I’ve studied—and used personally—to keep my heart in top shape.

Full Show Notes: https://bengreenfieldlife.com/lnraw06/ Welcome to RAW—my unfiltered solo podcast (hosted on LIFE Network), where you get the real, behind-the-scenes version of my life: the biohacking experiments I’m running on myself, the protocols I’m building and breaking, the tools and tech I’m stress-testing before anyone hears about them, the ideas in physiology, performance, and longevity I’m diving into, the beliefs I’m questioning, the routines I’m refining, and the unconventional stuff I’m actually doing day to day—no gloss, no script, just a direct line into what I’m thinking, testing, discovering, and living in real time. In this episode, we go deep into the “RAW” terrain of jaw mechanics—think controversial, awkward, and a tad nerdy, but game-changing for health. It all starts at a cocktail party when a Sherlock Holmes-style dentist spots red flags just by looking at his mouth. Cue a year-plus journey into bioesthetic dentistry, mindfully chewing food, and mastering “mewing” (tongue and jaw posture that even changes your face shape). What’s the big actionable win? Stop ignoring your mouth! Rethink your mechanics, posture, and oral hygiene—ditch the fluoride, embrace hydroxyapatite toothpaste, train your tongue to suction to your palate, and breathe through your nose like a pro.

Full Show Notes: BenGreenfieldLife.com/nicknorwitz In this episode with Dr. Nick Norwitz, you’ll get to discover how a Harvard-trained MD/PhD used a simple, eyebrow-raising experiment with Oreos to challenge conventional thinking on cholesterol, metabolism, and the stories told about health. We dive into his now-viral “Oreo experiment,” where adding Oreos to a ketogenic diet dropped his LDL cholesterol faster and more effectively than a high-intensity statin—an unexpected outcome that opens the door to deeper questions about lipid markers, risk factors, and how the body actually processes dietary fats. Nick Norwitz MD PhD is a researcher-educator whose mission is to “Make Metabolic Health Mainstream.” He graduated Valedictorian from Dartmouth College, majoring in Cell Biology and Biochemistry, before completing his PhD in Metabolism at the University of Oxford and his MD at Harvard Medical School. Nick has made a name for himself as a clinical research and metabolic health educator, speaking and writing on topics ranging from brain health, the microbiome, mental health, muscle physiology, mitochondrial function, cholesterol and lipids, and so on.
