Full Show Notes: bengreenfieldlife.com/pranamaya In this fascinating episode, I’m coming to you from the breathtaking shores of Belize, at a one-of-a-kind wellness resort called Prana Maya. In this episode, I sit down with Dr. Mara Kevan and Steve Hall, the passionate visionaries behind this toxin-free oasis, to share what makes this place and their approach to health so extraordinary. From the moment I arrived, I was struck by the pristine environment, the focus on farm-to-table organic cuisine, and the way everything is designed to help you leave feeling better than when you arrived. We dig into everything—why food is truly medicine, how Mara combined her background as a rock-and-roll tour manager with years of medical and holistic wellness expertise, and how Steve’s entrepreneurial journey led him to build this literal paradise on the world's second-largest reef. You'll also find details on our Boundless Couples Retreat, which Jessa and I are hosting at Prana Maya from November 10–14, 2026, where you'll have access to five days of daily workouts, relationship workshops, and luxury biohacking treatments inside a stunning oceanside setting.  Steve Hall is a serial entrepreneur whose four-decade career spans construction, apartment communities, assisted living, and drug and alcohol rehabilitation, with Prana Maya representing the bold next chapter of that journey. Dr. Mara Kevan is a licensed acupuncturist and functional medicine physician with over 20 years of clinical experience and an oncology specialty, who also spent years managing world tours for the Rolling Stones and luxury travel for some of the most discerning names in music, film, and politics before merging both worlds into the retreat experience she offers today.

Prayer, kindness, contentedness, honor, love, trust, obedience, abundance, intention, courage—here's exactly how I got to each word and what I'm doing with them. Episode Summary As I promised last week here are all 10 of my personal identity inversions, laid bare. In part 2 of the Identity Inversion series, I walk you through the full exercise I completed during an 8-hour personal retreat—2 hours each morning across 4 days—revealing the blind spots, weaknesses, and patterns I identified in my own life and the single words I'm using to redraw my identity. You’ll learn about everything from my impatience with imperfection to my fear of trying new things as I age. I also share practical tips for what to do with your list once you have it, including a surprisingly useful hack for categorizing your inversions. Question of the Day 🗣️ If you did this exercise right now, what's the first identity pattern that comes to mind, and what might your inversion word be? Key Takeaways This exercise took me 8 hours across 4 mornings during a personal retreat—and I recommend everyone schedule 3 to 5 days annually for exactly this kind of self-reflection work. I identified 10 inversions, each following the framework: describe the pattern in a paragraph, name the redemptive opposite in a sentence, and distill it into one word. My 10 inversion words: kindness, prayer, contentedness, honor, love, trust, obedience, abundance, intention, and courage. Feeding the list into GPT revealed a useful categorization: love anchors why I live, prayer/trust/obedience anchor who I depend on, intention/courage anchor how I move, contentedness/abundance anchor how tightly I hold, and kindness/honor anchor how I treat others. This isn't about perfection or self-worship—it's about becoming better equipped to love God and love others with the purpose you've been given.

RAW is where you get the real, behind-the-scenes version of my life: the biohacking experiments I’m running on myself, the protocols I’m creating, 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. In this episode, I open up about one of the most powerful anchors in my family's life—our daily bookends. These are the routines my family and I use to start and end each day with intention, connection, and purpose. I walk you through our morning huddle, where we check in, talk schedules, share a devotional, and pray together using the ACTS method. And at night, we gather for a family dinner complete with song, prayer, game time, and meaningful conversation—no matter how busy our days have been. I share not just the how, but the why behind these practices, emphasizing their impact on raising well-rounded kids, building family legacy, and nurturing relationships. Whether you've got a spouse, roommates, or a big family, I'm giving you a roadmap you can adapt to create magic and togetherness in your own home. Hope it inspires you to try something new—thanks for joining me on this RAW episode!

*In this episode, you'll discover a three-step framework for exposing the unconscious patterns quietly running your life and learn exactly how to flip each one.* ## Episode Summary In this episode, I introduce a very helpful life transformation framework called “Identity Inversion.” It's a simple exercise I designed (based on my own self-experimentation!) for identifying unconscious patterns, habits, and identity traps that are keeping you from becoming the best version of your broken self. Using two relatable examples (a man addicted to the gym for self-worth and a woman addicted to productivity for approval), I’ll walk you through a three-step process: describe the pattern in a paragraph, name its redemptive opposite in a sentence, then distill it into a single word that becomes the key to redrawing your identity. Next week, so you can get a really concrete idea of what this looks like, I’ll share my own 10 identity inversions. ## Question of the Day 🗣️ What's one identity pattern you've been running on autopilot, and if you flipped it, what single word would describe who you'd become? ## Key Takeaways How you live your days is how you live your life, and chances are, you are stuck in a hypnotic trance of habits shaped by old desires, environments, and upbringing that quietly became your identity. The Etch-A-Sketch metaphor: your daily habits get drawn together to form your identity, and sometimes you need to shake the board and redraw it. Identity Inversion is a 3-step exercise: describe an identity pattern in one paragraph, name its redemptive opposite in one sentence, then distill that into one single word. Example: A man whose identity is wrapped up in gym performance discovers his inversion word is "confidence," meaning being secure regardless of how his body looks. This isn't self-worship or moral polish, because growth disconnected from loving God and loving others always stalls out or turns inward. ## Timestamped Outline ⏱️ 00:00 – Introduction: Weekly newsletter podcast & how to subscribe 00:25 – Recap: Last week's episode on brokenness and acceptance 00:49 – The shift: becoming the best version of your broken self—not for yourself, but to serve God and others 01:10 – First step: Identif

Full Show Notes: bengreenfieldlife.com/498 In this solosode I kick off by talking about whether isometric training is worth your time, covering both my own fitness habits and the newest research, particularly for runners and joint health. I also unpack a buzzworthy study on how just 10 minutes of vigorous exercise daily can be a powerful longevity booster compared to longer, lighter workouts. I share why I no longer personally use metformin, and instead, offer my favorite natural alternatives for better blood sugar control—like berberine, fiber, cinnamon, and simple routines like salads and walks. Plus, I get into brain health, explaining the roles of ketones, methylene blue, and near-infrared light for cognitive performance and protecting against issues like Alzheimer’s. At the end, I answer listener questions on optimizing DHT levels, natural insulin-sensitizers, and keeping your hair healthy even if you’re on testosterone.

Being Boundless vs. Being “Broken” Why you should accept that you are broken and how that changes everything about the way you pursue health. Episode Summary In this episode, you learn about my lifelong obsession with perfection nearly ruined my ability to enjoy anything—sports, relationships, and even the pursuit of health itself. From golden child syndrome to slowly dropping out of sports I couldn't podium in, to the pain of losing my father, I lay it all out. This episode explains why none of the biohacking matters if you can't first accept that you're broken and find happiness in the journey anyway. Question of the Day 🗣️ Where in your life has the pursuit of perfection quietly stolen your joy, and what would it look like to let that go? Key Takeaways My identity was built on perfection from a young age—good grades, sports success, bodybuilding by 14—and anything that fell short felt like a threat to who I was. That obsession drove me to quit tennis, triathlons, and obstacle course racing the moment I couldn't finish on top. The hardest truth: my demands for perfection strained my relationship with my dad, and when he died of cancer, I felt like I'd failed my final attempt to "fix" him. We're all broken—our bodies and brains break down—and no amount of biohacking changes that. It's not until we stop trying to be perfect that we can actually savor the journey of becoming the best version of our broken selves.

A morning-to-bedtime blueprint for living more like your ancestors without a hyperbaric chamber, a hippie grocery bill, or a single scoop of overpriced supplement powder. Episode Summary In this final part of my 4-part “Ancestral Mismatch” series, I walk you through a complete sample day that ties together everything we've covered—hormesis, environment, and nutrition—into one practical, affordable routine.  From throwing open your curtains at sunrise to donning a $20 red light headlamp at bedtime, I show you exactly how simple (and cheap) it is to align your modern life with your ancestral biology. No hyperbaric chambers, no organic coffee enemas, no umbilical cord stem cell infusions. Just the basics done right. For your convenience, here are parts 1–3 of this series on fighting the “ancestral mismatch” and the uphill battle against living in a toxic, modern, industrialized world: Are We Just Modern Zoo Animals? The Ancestral Mismatch (Part 1) Are We Just Modern Zoo Animals? The Ancestral Mismatch (Part 2) Are We Just Modern Zoo Animals? The Ancestral Mismatch (Part 3) Question of the Day 🗣️ Looking at this sample day, which piece are you already doing—and which one are you most likely to try first this week? Key Takeaways A fully ancestral-aligned day doesn't require expensive biohacking equipment—it's built on natural light, filtered water, movement, whole food, and intentional rest. My morning routine is simple: sunlight, journaling or prayer, filtered water, 20 minutes of light movement and stretching outdoors, followed by a cold shower. "Movement snacks" throughout your workday—jumping jacks, push-ups, air squats every 45 minutes—replace the need for a long gym session.

Full Show Notes: bengreenfieldlife.com/hungercode On this episode, I got to geek out with Dr. Jason Fung and unravel why calorie counting alone doesn’t explain our weight struggles. Dr. Fung used jaw-dropping stats—like nearly identical calorie consumption between nations with wildly different obesity rates—to illustrate how hormones, digestion, and even the microbiome play a much bigger role than just numbers.  We also broke down the three types of hunger—homeostatic, hedonic, and conditioned—and explored how ultra-processed foods hijack our biology. Dr. Fung shared that ditching those foods is his top strategy for conquering hunger, while I revealed how staying busy and using GLP-1s can help curb appetite during fasting or travel.  Dr. Jason Fung is a physician (kidney specialist), researcher and New York Times best-selling author currently practicing in Toronto, Canada. trained in Los Angeles and Toronto and currently practices as a nephrologist (kidney specialist). His books, including The Obesity Code, The Complete Guide to Fasting, The Diabetes Code and The Cancer Code have challenged conventional thinking about these diseases, and introduces dietary strategies to manage them.

Discover why cotton candy can beat a corn dog, how the perimeter-of-the-store hack simplifies everything, and what it really looks like to eat like your great-grandparents. Episode Summary In part 3 of the “Ancestral Mismatch” series, Ben Greenfield delivers three no-nonsense dietary strategies that anyone can implement without breaking the bank or setting foot in an overpriced health food store. You'll learn why fried seed oils are more damaging than sugar (and why Ben would choose cotton candy over a corn dog every time), how to avoid ultra-processed foods by shopping the perimeter of any grocery store, and why sourcing your food matters for your health, animal welfare, and the planet. Ben even drops his go-to travel grocery list that works at any supermarket on Earth. Question of the Day 🗣️ What's one ultra-processed food you know you should ditch but keep reaching for, and what whole-food swap could replace it? Key Takeaways - Rancid heated seed oils in fried foods are more damaging long-term than sugar—lipid oxidation products (LOPs) become the building blocks of your cells and contribute to chronic disease risk. - Ultra-processed foods (UPFs) are engineered to be addictive, stripped of nutrients, and loaded with additives, preservatives, and oxidized oils—shop the perimeter to avoid them. - You don't need an expensive health food store—Ben's entire travel grocery list (rotisserie chicken, berries, avocados, sardines, nuts, yogurt, dark chocolate) costs under $40 and lasts days. - Farmer's markets from May through October give you access to local, sustainably grown food—and many farmers will sell you a quarter or half cow and ship it in batches. - Skip the fluff labels ("natural," "farm fresh")—look for USDA Organic, Pasture-Raised, MSC Certified, and Certified Humane instead.

I reveal why the length and intensity of your walking sessions matter more than you think, and how longer walking bouts can trump simply chasing that 10,000-step goal.  I also revisit a forgotten but powerful heart-protective hack—adding pomegranate juice to your routine to help reduce arterial plaque and lower your blood pressure.

*The air you breathe, the light you see, and the water you drink have all been quietly sabotaged by modern life—here's how to fight back without ripping your house apart.* Episode Summary In this episode, we shift from last week's hormesis deep-dive to the second weapon in your ancestral mismatch arsenal: your environment. You'll discover how degraded air quality, flickering LED lights, contaminated water, and invisible EMFs are silently wrecking your sleep, fogging your brain, and loading you with toxins—then get a practical, budget-friendly environmental audit you can start this weekend. Question of the Day 🗣️ What's one thing in your living or working environment you've always suspected might be affecting your health—but haven't done anything about yet?  Key Takeaways Your environment may be undermining your health more than your diet or exercise routine—air, light, water, and EMFs are the invisible variables most people ignore. Modern indoor air quality, fluorescent lighting, treated water, and constant wireless exposure create a toxic soup our biology was never designed to handle. You don't need a full home renovation to make a meaningful difference—standalone HEPA filters, incandescent bulbs, countertop RO systems, and airplane mode are powerful starting points. A basic environmental audit is one of the highest-ROI health moves you can make with minimal cost. This is part two of a three-part ancestral mismatch series—next week: food.

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.
