How To Turn Your Brain’s Immune Cells Into Alzheimer’s Defenders (& Why The Amyloid Drugs Fall Short), With Dr. David Perlmutter

59 min

Full show notes: bengreenfieldlife.com/braindefenders In this episode, board-certified neurologist Dr. David Perlmutter joins me to talk through his new book, Brain Defenders, and his case that the beta-amyloid drugs for Alzheimer’s (drugs that target a sticky brain protein) haven’t delivered the results many hoped for. You’ll discover how microglia, your brain’s own immune cells, can protect your neurons or damage them, and what may tip them in either direction. You’ll also learn why the metabolism of those cells may mirror the metabolism of your whole body, which could put more of your brain’s future in your hands than you might expect. David and I also dig into the gut-brain link, from ultra-processed food to fecal transplants, the blood tests he recommends, and how herbicides like glyphosate and paraquat, as well as wildfire smoke, may affect your brain. You’ll learn about duckweed, minocycline, and RNS60, a nanobubble saline being studied in stroke and amyotrophic lateral sclerosis (ALS), what the glucagon-like peptide-1 (GLP-1) trials in Parkinson’s and Alzheimer’s reported, my own accidental retatrutide injection, and the lifestyle trial that reported improvements in early Alzheimer’s after 20 weeks without using any drugs. You can find his new book, Brain Defenders, here.

We also dig into questions from the AI-powered wisdom keepers in Marc’s new book, You’re Invited, including which practices I’d keep if none of them extended my life and what I finally stopped doing. You’ll learn why exercise beats piling on biohacks, how I stay true to my creative work, my daily, weekly, and annual reflection rituals, what excites me in the longevity space, and what my late father would be proudest of in how I’m raising my sons.

48 min

Full show notes: BenGreenfieldLife.com/jaspr3 In this episode, repeat guest Michael Feldstein, founder of Jaspr, joins me in my Idaho studio to make the case that synthetic fragrances are the new secondhand smoke. You’ll hear why the air freshener in your Uber may be doing more harm than you think, how fragrance dulls your sense of smell and even your digestion, and what Michael does to keep his air clean on the road when he can’t ship a Jaspr ahead of him. We also dig into the research tying air quality to cognitive performance, from MLB umpires to chess players to the healthy buildings work of Harvard’s Dr. Joseph Allen, plus what Michael thinks about stacking nasal strips with clean air. You’ll learn how he built Kindling Academy in Austin to be the healthiest school in America, the humidity range that keeps mold and bacteria in check, how to upgrade your car’s cabin filter, and why gyms and dental offices have some of the worst air quality you’ll breathe.

The NEW Peptide That Keeps Your Hair From Going Gray (& The Future Of NOT Losing Your Hair!), With Dr. Yaron Fuchs of Prologue.

46 min

Full show notes: BenGreenfieldLife.com/prologue In this episode, stem cell scientist Dr. Yaron Fuchs reveals how an accidental lab finding, a compound that turned every hair white, led to Prologue, a peptide serum built to help you keep the natural hair color you still have. You’ll hear why hair goes gray in the first place, how the stem cells that run your pigment “factory” decide whether to live or die, and how his team shrank a large protein into six peptides small enough to reach the follicle. You’ll also learn the surprising story behind finasteride, from castrated men who never went bald to a rare mutation in the Dominican Republic, and why hair loss medicine has barely advanced in decades. We dig into what his clinical study found, when to start treatments if you want to stay ahead of your first grays, and whether a red light helmet has any real benefits for hair. You’ll also hear how I fit the serum into my morning routine, and how Dr. Fuchs’ lab can grow and test your own hair follicles from a urine sample.

Procrastination Isn't A WILLPOWER Problem: How To Multiply Your Time *Without* Working Harder, With Rory Vaden

1 hr 5 min

Full show notes: BenGreenfieldLife.com/rory In this episode, Rory Vaden, author of Take the Stairs and cofounder of Brand Builders Group, tackles why people who know exactly what to do still don’t do it, and why the problem is rarely a lack of information. You’ll hear the three types of procrastination, why discipline has less to do with willpower than with vision, and how to multiply your time by spending it on things that create more time tomorrow. You’ll also learn where biohacking crosses from smart tools into shortcuts, why buffalo run straight into storms, and the return-on-time math behind the AI tool I built to tame my WhatsApp groups, along with why automating chaos only creates chaos faster. We dig into overloaded morning routines, the social pressure of living in an escalator world, and the photo of my 80-year-old self that hangs on my wall, plus how to grab Rory’s Wealthy and Well-Known audiobook for free.

The Ultimate Biohacker’s Guide To Pre & Post-Surgical Prep: Technologies, Peptides, Stem Cells, Nutrition, What NOT To Do & Much More, With Dr. Reza Jazayeri

1 hr 20 min

Full show notes: BenGreenfieldLife.com/surgicalathlete In this episode, orthopedic surgeon Dr. Reza Jazayeri shows you how to prepare for and recover from surgery like an athlete, from the strength you build beforehand to the nutrients, technologies, and anesthesia choices that shape how you heal. You’ll hear why your biology, not the surgeon’s hardware, is now the weak link, why weak quads going into a knee surgery predict how well you function afterward, how he harvests your own cells mid-operation, and why going into surgery starving is outdated. He also explains why the protein guidelines most people follow fall short after an operation, and what NASA’s bed rest studies revealed about the best way to hold on to muscle. You’ll also learn which amino acids, vitamins, and minerals he uses before and after an operation, where pulsed electromagnetic field therapy (PEMF), hyperbaric oxygen, and red light fit into recovery, which supplements to stop beforehand, and how too much zinc can block copper. We dig into ketones, growth hormone, peptides, and the one-week pause he puts on blood vessel-building peptides after surgery, and I share the stack I would personally use, plus why I banked my own bone marrow stem cells and fat stem cells years ago.

Why Fitness, Anti-Aging, Money & Sex Won’t Make You Happy (& The Routine That Builds True Fulfillment), with Vince Del Monte

1 hr 10 min

Full show notes: BenGreenfieldLife.com/vincepodcast In this episode, repeat guest Vince Del Monte, once known as the “skinny guys savior,” opens up about the divorce that broke his eight-figure life wide open, and what it taught him about God, money, and manhood. You’ll hear how a pastor’s kid who swore divorce would never happen to him fell for the three lies driven men believe about their worth: you are what you do, what you have, and what other men think of you. He shares the habits that cost him his marriage, why loving your business more than your wife has become “a societal form of adultery,” and the night his wife said “I’m done” that put him on his knees and into therapy. You’ll also learn how his prayer life went from performance to a 4 a.m. hour with God, why quiet time beats a perfect WHOOP sleep score, why he threw his trackers in the garbage, and how he stopped letting his body determine his worth. I also share the near-divorce I tell in my documentary, Boundless: The Man Who Became Human. We talk about the “alpha orphan spirit,” shutting down his mastermind, quitting testosterone replacement therapy, alcohol, and caffeine in the same year, and how he’s now leading a relationship in purity. If you’re a woman listening, this is one to send to a man in your life.

How To Fix Loose Skin After GLP-1 Weight Loss, How Much Protein To Eat In A Calorie Deficit & 8 Bodybuilding Myths Busted

50 min

Full show notes: BenGreenfieldLife.com/507 In this episode, you’ll discover how much protein to eat in a calorie deficit to hold on to muscle, which bodybuilding myths you can drop, and what can help tighten loose skin after GLP-1 weight loss. I walk you through a new meta-analysis of 29 studies on dieting lifters, why I set my own target higher at 1 to 1.5 grams per pound, and whether switching up exercises builds bigger arms. You’ll also learn how close to failure you really need to train, why fasted cardio may not burn more fat, and why skin sags when weight comes off fast, including the 7% of facial volume lost per 10 kilograms. I also dig into whether lifting makes women bulky, whether cardio kills your gains, whether you need to eat every three hours, and whether creatine is a steroid (it’s not). You’ll hear why I lift heavier loads on Nautilus machines, the essential amino acids my sons and I take twice daily, why I train fasted on ketones and amino acids, and my morning coffee fat-loss routine. We finish with strategies for tightening loose skin, including collagen, an at-home iRESTORE red light panel (use code BENPRO for $25 off), clinical treatments, and surgery, plus how to keep loose skin from deciding your self-worth.

Ex-CIA Officer: How To Beat A Polygraph, Recover Like A Spy & Read Anyone, With Andrew Bustamante

54 min

Full show notes: BenGreenfieldLife.com/spysecrets In this episode, I’m re-airing my conversation with former covert CIA officer Andrew Bustamante, founder of EverydaySpy. My friend Adam Wenguer introduced us by saying Andrew was great at marriage, homeschooling, and biohacking, and that he used to be a spy. You’ll hear what a polygraph really measures, how the CIA rebuilds officers after an operation, and the recovery tools he leans on, including L-theanine, CBD oil (use code BEN15 for 15% off), and watered-down electrolyte drinks (get a free sample pack with any drink mix order). Andrew walks through his CIA morning routine, from a big glass of water and a Transcendental Meditation® mantra to berries instead of coffee, plus why the agency wants your heart rate up early and why he shuts off screens 90 minutes before bed. You’ll also hear about the two popular sleep aids I think cut into your REM sleep, the “perspective” exercise that changed his marriage, the “false dilemma” that heads off most bedtime fights with kids, and how I talk to my own sons about porn. We also cover why he journals in fragments and turns them into spreadsheet dashboards, and why switching up your workouts beats the same treadmill run every day. If you want to go deeper, you can find his new book, Outsmart Everyone, here.

Doctors Gave Him 4 Years To Live: How A Biochemist REVERSED His Heart Disease - With Patrick Theut

57 min

Full show notes: BenGreenfieldLife.com/healthyheart In this episode, I’m re-airing my conversation with biochemist and engineer Patrick Theut about how he cleared the plaque from his own heart. Patrick was 48, winning 5Ks and playing ice hockey when he passed every test in a Mayo Clinic physical, then asked for one more scan they said he didn’t need. It came back with his left main artery lit up, and a cardiologist gave him four years to live. I went through something very similar myself, which is why this one stuck with me. You’ll hear how gut bacteria help make vitamin K, how a common antibiotic can wipe them out, the health crash that sent his calcium score soaring, and the vanadium protocol he used to rebuild his pancreas, plus my company’s bitter melon blood sugar formula, Kion Lean. We get into the statin experiment he ran on himself, why vitamin K may help athletes train harder, what to know if you take blood thinners like warfarin, and his bare-minimum protocol, from magnesium (use code BEN15 for 15% off) and vitamin D to vitamin C. We close with his take on statins, the heart marker he thinks matters next, his once-a-day eating, and the fermented Paleovalley beef sticks (use code PVFRIEND15 for 15% off) I’ve been working my way through. If you want to try Patrick’s vitamin K blend for yourself, you can find Koncentrated K here.

The Little-Known “Throwaway” Gland That Is CRITICAL For Immunity (& The Unexpected Peptides To Support It) - With Abud Bakri

52 min

Full show notes: BenGreenfieldLife.com/thymuspodcast In this episode, I sit down with internal medicine physician Dr. Abud Bakri to talk about the thymus, the small gland on top of your heart that trains your immune system and starts shrinking as soon as you hit puberty. You’ll hear what speeds that shrinkage up, from birth control and testosterone therapy to chronic infections, stress and a leaky gut, why Korean eunuchs lived longer, and which blood markers, like the ratio of helper to killer T cells (CD4-to-CD8 ratio), give you a window into how your thymus is doing. We get into thymulin and zinc, thymosin alpha-1, the Russian thymus extract Thymalin, and whether eating sweetbreads does anything at all. You’ll also hear my bedtime stack of epitalon and Pinealon, why Abud shines red light on his sternum, the overlooked link between the thymus and testosterone, why he takes 40 times my dose of body protection compound 157 (BPC-157) for injuries, and the red flags to watch for before you inject any peptide. We also cover natural killer cell treatments, the libido peptide being tested for weight loss, and why Abud thinks lactoferrin and colostrum are about to catch on.

The High Carb vs. Low Carb DEBATE: Which One Wins For Your Metabolism? With Dr. Eric Westman & Jay Feldman

54 min

Full show notes: BenGreenfieldLife.com/lowcarbhighcarb In this episode, I'm re-airing the first debate ever held on the Boundless Life podcast, with repeat guest Jay Feldman and Duke obesity medicine physician Dr. Eric Westman going head to head on whether your cells run better on carbohydrates or fat. The carbs-are-good, carbs-are-bad argument has only gotten louder, and this is still the best version of it I've heard. You'll hear Jay's case that burning fat creates more oxidative stress and drives up stress hormones like glucagon and cortisol over time, and Eric's case from decades of reversing type 2 diabetes in his clinic. We get into the KetoSAge study that pulled keto-adapted women out of ketosis, the KETO Trial on keto dieters with very high LDL cholesterol, what a failing heart actually burns, and why keto adaptation can take months. We close on the membrane pacemaker theory of aging, survival versus thriving, how I scale my own carbs to training and travel, and the three carb levels Eric lays out in End Your Carb Confusion. Whether you eat keto, high-carb, or somewhere in between, this debate will sharpen how you think about fuel.

How Fixing Your THYROID Improves Fat Loss, Hair, Skin & Energy, With Dr. Amie Hornaman

46 min

Full show notes: BenGreenfieldLife.com/thyroidhealth In this episode, I'm re-airing one of the most comprehensive thyroid conversations I've ever had, with repeat guest Dr. Amie Hornaman. Six doctors told her she was normal while she gained 25 pounds in contest prep, and the seventh finally found the goiter. You'll hear why thyroid stimulating hormone (TSH) on its own misses most of the picture, how reverse T3 can block your active thyroid hormone at the cell door, and why only 2% of hypothyroid patients do well on T4 alone. We get into T2, the thyroid hormone almost nobody talks about, and the Thyroid Fixxr® (use code BEN10 for 10% off) I took to Italy. Dr. Amie also covers what years of low-carb eating does to T3, whether animal glandulars help or backfire, where iodine and selenium fit, the peptides she uses for Hashimoto's, and why testosterone matters so much for women. If you've been told your thyroid labs are normal and you still feel terrible, this one is for you.

Longevity MASTERCLASS: Biological Age, Mitochondrial Repair & The Superhuman Protocol

51 min

Full show notes: BenGreenfieldLife.com/ultimatelongevity In this episode, I'm pulling the best of three longevity conversations into a best-of compilation: blood oxygen as the root of nearly every disease pathway, the molecule that clears out your worn-out mitochondria, and a 61-year-old engineer who is out-aging tech billionaires on a normal budget. All three come at the same problem from completely different directions. First, Gary Brecka on what two decades of predicting death for life insurance companies revealed, why he says the presence of oxygen is the absence of disease, and the magnetism, oxygen and light protocol he built out of it, including a budget version of exercise with oxygen therapy you can do with a training mask. Then Dr. Anurag Singh on the three ways your immune system ages, why he thinks immune aging drives the rest of aging, and what the Mito-Immune trial found when middle-aged adults took Mitopure® (use code BEN20 for 20% off) for four weeks. And finally Dave Pascoe, who got the telomeres of a 68-year-old at age 50, turned it around, and now posts a pace of aging near the top of the Rejuvenation Olympics leaderboard while eating two meals at a sitting and taking no testosterone. I also share the red light routine I run for the first hour of every morning.

How To Microdose GLP-1s Correctly: Lose The Fat, And KEEP The Muscle - With Dr. Tyna Moore

59 min

Full show notes: BenGreenfieldLife.com/drtyna I'm re-airing my conversation with Dr. Tyna Moore about GLP-1s because almost everything she said about them is still being misunderstood, and she was one of the earliest voices advocating for using these drugs at very low doses. When we recorded, the internet had largely decided GLP-1 agonists were terrible: muscle wasting, "Ozempic face," suicidality, and more. Tyna's take was very different, and much of what she discussed has held up surprisingly well. Not everything, though. The big Alzheimer's trials found that GLP-1 treatment did not significantly slow disease progression. I was the guinea pig for this one. The week before our interview, I injected one-tenth of the standard semaglutide dose, and Dr. Moore told me on air that even that was far too much for me. She was right. It took me three days to get through one porterhouse steak. You'll hear what dosing for appetite control rather than appetite suppression actually looks like, why a natural GLP-1 stimulator may not do much if the gut cells that release GLP-1 have stopped responding, what the thyroid cancer black box warning is actually based on, what that widely shared suicidality study really measured, and how to protect your muscle while using these drugs. Dr. Tyna Moore also shares where she sends people now that she has stopped taking new patients, which is The Menopause Rebellion, her community for Gen X women covering hormones, metabolism, muscle building, GLP-1s, and peptides.

This Man Thinks "AGI" Could Allow Humans To Live Forever, With Dr. Ben Goertzel

53 min

Full show notes: BenGreenfieldLife.com/AGIpodcast In this episode, you'll hear how artificial intelligence is actually being pointed at aging right now, including an algorithm picking which Chinese herbs extend a fruit fly's life, plus whether the biological age test you just paid for means anything at all. My guest is Dr. Ben Goertzel, who popularized the term artificial general intelligence, runs a decentralized AI network, and is chief scientist at Hanson Robotics. We get into the long-lived fruit flies his team works on at Genescient, the roughly five traditional Chinese herbs an AI selected from a database and combined in ways that more than double a middle-aged fly's life, and why the AI mixes them in combinations no Chinese medicine practitioner ever would. You'll also learn why he says today's biological age tests are "a little dodgy," why large language models keep handing you the existing literature instead of generating new science, and what the extracellular matrix has to do with whether your whole body is aging well. We close on the engineered enzymes he thinks will eventually re-sculpt the genome of every tissue in your body, my own follistatin gene therapy result, and the band he plays keyboards in with a humanoid robot lead singer.

How To Increase Fertility (For Males & Females!), How Much Sleep Is Too Much (Or Too Little)? & A "Minimalist" Approach To Increasing VO2 Max! Solosode #506

41 min

Full show notes: BenGreenfieldLife.com/506 In this episode, you'll discover three things I've been asked about constantly: whether the melatonin heart failure headline is worth worrying about, how much sleep is actually too much or too little, and the shortest route to a higher VO2 max. I break down what the melatonin study did and did not reveal, why a key prescription detail changes how the findings should be interpreted, and why I still use high-dose melatonin for jet lag. Then I move to VO2 max, including the Norwegian 4x4 explained the way I used to coach it, what the sprint interval research says about doing it faster, and the tools that work beyond exercise, from heat acclimation to altitude to correcting an iron deficiency. You'll also hear what a new Nature study of half a million people found about the 6.4 to 7.8 hour sleep window, and why I still sleep less than that on purpose. Finally, fertility for men and women. On the male side, scrotal temperature, timing intercourse around ovulation, the lubricant problem nobody mentions, and the supplements with real human data behind them, from L-carnitine and CoQ10 to zinc and shilajit (use code GREENFIELD for free shipping). On the female side, ovulation tracking, acupuncture, CoQ10 before egg retrieval, and inositol. Plus how to preserve fertility if you're on testosterone replacement therapy (TRT).

From 15 Bathroom Trips A Day To A Clean Gut: Fixing Poop Issues NATURALLY - With Josh Dech

1 hr 2 min

Full show notes: BenGreenfieldLife.com/gutsolution In this episode, you'll meet Josh Dech, a former paramedic turned Crohn's and colitis consultant who argues that all three things Western medicine says about inflammatory bowel disease are wrong: it's not genetic, not classically autoimmune, and not idiopathic. We walk the research trail from a 1988 Swedish twin study through the NOD2 gene to the genome-wide studies that mapped hundreds of risk loci and still explained only a sliver of the disease, and into the numbers that worry him most, where the West has 6% of the world's population but 60% of its bowel disease. You'll also get the practical half: his sequence to help stop the active cause first, then how he suggests opening the seven drainage pathways, why he takes a full history before ordering a single test, where peptides belong, what is really coming out of people during a parasite cleanse, and why $30,000 fecal transplants keep failing. Near the end, it turns personal and a little gross, into my own dairy problem and the biomechanics of a proper bowel movement.

A Memory & Learning Expert Reveals His Secrets To Training Your Brain & MASTERING Your Mind, With Jim Kwik

1 hr 3 min

Full show notes: BenGreenfieldLife.com/limitlessdaily In this episode, you'll hear repeat guest Jim Kwik talk about cognitive offloading and where the line sits between using your phone as a second brain and letting your own memory go slack. We dig into the MIT study that scanned essay writers' brains and found the ChatGPT group remembered the least of what they wrote, what London cabbies' brains looked like before satellite navigation, why movement drives brain-derived neurotrophic factor (BDNF), and why racket sports and dance sit at the top of the longevity list. You'll also learn Jim's BUILD framework for using AI as a critic rather than an answer machine, how to write an affirmation your brain will not immediately reject, the white bear effect that makes "don't check your phone" the least useful instruction you can give yourself, why the 15 to 45 minutes of sleep inertia after you wake carries more weight than any other window in your day, and the four daily basics Jim ranks above every device in his house. We close with the 40 Hz gamma protocol I now use in the early afternoon, and the surprising effect it's had on how quickly I fall asleep at night. All of this comes straight out of Jim's new book, Limitless Daily, designed to give you one simple, actionable lesson each day for an entire year.

This Guy Healed Knee Arthritis *Without* Surgery (& Chest-Pressed 555lbs For 14 Reps) - Cellular Hydration Secrets With John Jubilee

51 min

Full show notes: BenGreenfieldLife.com/jubilee In this episode, John Jubilee makes the case that almost everything you have been told about hydration is beside the point. His argument is that the water is not the problem, the cell is: that a membrane gets progressively harder to penetrate as you age, that your water and your supplements simply bounce off it, and that until you change the membrane itself, nothing else you do gets in. He arrived at that after a decade of doing everything right, a gallon of water a day and a thousand dollars a month in supplements, and still having high blood pressure and no cartilage left in either knee.  You'll hear the question he asked every one of his doctors that none of them could answer, the $11,000 machine he bought in 1997 to answer it himself, and the Energized Health protocol he built out of it. You'll also get the practical layer that costs nothing: the three steps he tells everyone to start with, the balls-of-your-feet walking trick and the soleus study behind it, his case for MSM, and why he refuses to recommend alkaline, structured, or reverse osmosis water. Then it turns personal, into cellular trauma, the ACE study, and why he believes a flawless diet still leaves something unaddressed.

How To Build An Ideal Workday With Power Naps, Email Delegation & Deep Work Tactics, Featuring Chandler Bolt

59 min

Full show notes: bengreenfieldlife.com/bolt In this episode, Chandler Bolt and I talk about how we've each landed on almost identical daily systems for running a company, and the one place we still disagree. Chandler makes the case that a book is a business asset rather than an income stream, explains what it actually costs to buy your way onto the New York Times list, and then walks through the routine underneath all of it: a nap he hasn't skipped in years, a morning he refuses to let anyone schedule over, and a phone that geofences itself into work mode the moment he arrives at the office. You'll also hear why he self-experiments relentlessly yet refuses to wear a tracker. We get into the two metrics worth watching if you track nothing else, why the 30-minute nap ceiling is weaker science than you've been told, why a hot tub is harder on fertility than a sauna, what overhead LED lighting does to your afternoon and the BlockBlueLight bulbs I use instead, and why a manual WALKOLUTION treadmill desk beats a motorized one. Chandler also shares the airplane movement trick that got him mistaken for a lunatic by a stranger who later became a friend. Then we close on communication: being a default no, replacing calls with voice memos, and using SocialSweep to surface the connections already sitting in your phone.

How to Replace Sauna, Fasting, and Cold Plunge With a Pill (WARNING: Proceed at Your Own Risk!) With Dr. Sandra Kaufmann

55 min

Full show notes: bengreenfieldlife.com/pharma In this special repeat episode, Dr. Sandra Kaufmann breaks down which pharmaceuticals mimic the effects of things you already do for your health: what replaces a sauna session, what replaces a fast, what replaces a cold plunge (use code BENFORGE for $500 off select products), and what she takes with meals to blunt the damage from glucose spikes. I'm re-airing it now because of a new Nature paper finding that lithium is a naturally occurring brain nutrient, and that losing it may be one of the earliest steps toward Alzheimer's, at a dose in exactly the range Dr. Kaufmann described on this show years earlier. You'll hear why she prefers pioglitazone over metformin for autophagy, how a Japanese gastritis drug connects to Alzheimer's, and how she worked her way up on an emergency blood pressure medication, starting at a dose that nearly knocked her off her feet and climbing to 100mg with no effect at all. The centerpiece is lithium (code BGL10 for 10% off): why the doses hidden inside popular nootropics are a fraction of what she considers useful, and everything it appears to do beyond mood, from controlling a pore in your mitochondria to building bone and growing new neurons. You'll also get her honest take on gene therapy versus pharmaceuticals, why peptides underperform in an older cell, and which molecule finally knocked astaxanthin off the top of her ranking system.

The BIGGEST Step You Can Take To Reduce Microplastics, How To Get Rid of Back Pain, What You Need To Know About Heart Scans & More - Solosode #505

37 min

Full show notes: bengreenfieldlife.com/505 In this solosode, you'll get the latest on microplastics, spinal disc health, and what a heart scan sees that a cholesterol panel misses. A new seven-day trial pitted five plastic-avoidance strategies against each other, and the results tell you exactly where to spend your effort if you can't overhaul everything at once. You'll hear which plastic sources matter most and what I now take before bed with BrocElite® (use code BEN for 25% off your first month) to help clear microplastics from tissue. Then I get personal about my back. I'll walk you through my full-body MRI results, which show significant degeneration from L1 to S1, and explain why I still have almost zero back pain, from Dr. Stuart McGill's Big 3 to inversion hanging, the couch stretch, the founder stretch from Foundation Training, and my WALKOLUTION® treadmill desk ($100 off, enter your email for a unique code). You'll also learn why running was the only activity linked to healthier spinal discs in a study of more than 4,000 people, and why none of the sports people assume are hard on your back showed harm. Finally, you'll hear what a coronary CT angiography measures that your cholesterol panel cannot, why a 6,061-person study found plaque volume beats any standard risk calculator, what my own scan revealed, and the surprisingly simple thing that appears highly protective even when your plaque is already elevated.

The Myth Of The Perfect Health Routine: How To Raise Your HRV By Giving Up Control, With Justin Roethlingshoefer

1 hr 4 min

Full show notes: https://bengreenfieldlife.com/holyhealth In this episode with Justin Roethlingshoefer, you'll hear from a former NHL performance coach turned health entrepreneur whose new book, Holy Health, is the one I chose for my father-son book club this month. This is not another eat-honey-and-drink-milk Bible health book. Justin is a genuine biohacker who works with pro athletes worldwide, and he has woven deep spiritual and physiological science into the same framework. You'll learn why the modern obsession with optimization can quietly become idolatry, how the drive to control your metrics keeps your nervous system stuck in fight-or-flight and lowers your HRV, and the five "hearts" that trap high performers in striving. You'll also get the practical side: his full morning and evening rhythms, why he starts his day at 6 p.m. rather than at sunrise, the breathwork he does midday in the grass, his exact zone two and zone five weekly targets, and how he folds three and a half hours of zone two into family walks with a weighted vest. It's a conversation about doing less frantic optimizing and more intentional stewardship, and it may reframe how you think about every biohack you own.

Eat *This* If You Consume Seed Oils, Best Way To Combine Strength & Cardio, Peptide "Stacking" Rules & More! Solosode #504

27 min

Full show notes: https://bengreenfieldlife.com/504 In this solosode, you'll get the latest research on three questions I keep getting asked. First, seed oils: a brand-new randomized controlled trial put 52 adults on either a low or a typical Western intake of linoleic acid for 12 weeks, and the results are important less for what they found than for what they didn't. You'll hear why arachidonic acid didn't move, why EPA dropped instead, what that does to your inflammatory balance, which seed oils I still think are worth avoiding, and the one dietary adjustment that matters most if seed oils are part of your diet. You'll also learn the surprisingly small amount of strength training that delivers the biggest longevity payoff, according to a 30-year study of more than 147,000 people, plus why pairing it with cardio is the single best exercise combination for blood pressure. I break down concurrent training, the interference effect between AMPK and mTOR, and when combining strength and cardio in one session helps you versus when it holds you back. Finally, I answer a listener question on peptides with six practical rules for stacking them safely, including which ones should never share a syringe, which ones cancel each other out at the receptor, and an honest look at how thin the human evidence really is behind the popular Wolverine stack.

This 56 Year Old Mom Is Reversing Aging Faster Than Pro Biohackers On $106 A Month! With Julie Gibson Clark

57 min

Full show notes: https://bengreenfieldlife.com/juliepodcast In this episode with Julie Gibson Clark, I'm highlighting a throwback conversation because the gap it exposed has only gotten wider. There's a leaderboard called the Rejuvenation Olympics where people submit a blood test that measures how fast they're aging. When we recorded, Julie was a 55-year-old single mom in Phoenix making under $100,000 a year, sitting at number two in the world, aging at roughly two-thirds the speed of the calendar, and ahead of people like Bryan Johnson, who was spending $2 million a year chasing the same number. Her budget was $27 a month for a gym membership and $79 a month for a supplement. This February, Bryan Johnson opened an elite longevity program at $1 million a year with three spots, an interview process, and a requirement that you hire a dedicated assistant to keep up with the protocol. You'll learn what Julie actually does: sleep protected like it's sacred, walking and rucking, strength training and VO2 max work, a pile of vegetables every day, one supplement, prayer, and stillness. Nothing that requires an executive assistant. You'll also hear her full health history, from heavy metal toxicity and chelation therapy to the genetics that shaped her approach, exactly what she eats and when, her supplement stack, her sleep and sauna routines, and why she refuses to name a target lifespan. Now 56 and teaching as founding faculty at a longevity academy, Julie is proof that the affordable end of longevity practice still gets you remarkably far.

From Cocaine Dealing & Prison To #1 Health Podcast In The World, With Dylan Gemelli.

1 hr 0 min

Full show notes: https://bengreenfieldlife.com/dylan In this episode with Dylan Gemelli, you'll hear one of the wildest origin stories in the health world. Dylan went from college athlete to Milan model to cocaine dealer to a 15-year prison sentence, and came out on the Fourth of July with two felonies, no job prospects, and a decision to start over. Within a year he had a million YouTube subscribers explaining compounds almost nobody was talking about yet, and today he hosts the number one health and fitness podcast in the country. You'll also get the practical side: what SARMs really are and why he turned against steroids, what happened when a routine calcium score came back at 120 with an Lp(a) of 330, how he pushed back against the Mayo Clinic and got that number down into the 90s anyway, and what he learned about ejection fraction and chronic cardio the hard way. Dylan explains why he believes many biohackers are among the unhealthiest people out there, how stacking too many supplements and peptides creates redundancy that backfires, and which lesser-known peptides will rise in popularity.

Is This The Most Powerful Adaptogenic Plant Extract Known To Humankind? The SCIENCE of Black Seed Oil with Dr. Michael Murray

50 min

Full show notes: https://bengreenfieldlife.com/blackseedoil In this episode with Dr. Michael Murray, one of the most respected figures in natural medicine and the formulator of ThymoQuin®, you'll discover the science behind black seed oil: what thymoquinone actually is, why the full spectrum of the seed's compounds matters more than chasing a single active ingredient, and why it may be the most powerful adaptogen yet measured for lowering cortisol, dropping the stress hormone 22 to 44% in stressed people. You'll hear how it supports your gut by calming harmful bacteria without wiping out the good ones, the surprising dose range where it helps rather than harms your microbiome, and its effects on inflammation, metabolic health, blood pressure, blood sugar, sleep, and candida. Dr. Murray also explains what makes his USP-monographed ThymoQuin different from ordinary black seed oil, why keeping free fatty acids low keeps it active, how to spot adulterated products, and the simple daily protocol he follows himself at 68. It's a grounded, myth-busting look at one of the oldest plant medicines on earth.

In Defense Of Sunlight: The *Real Truth* About The Sun, Vitamin D, UVA, UVB, Sunscreen & More, With Rowan Jacobsen.

52 min

Full show notes: https://bengreenfieldlife.com/sunpodcast In this episode, journalist Rowan Jacobsen, author of In Defense of Sunlight, challenges everything you thought you knew about sun exposure. Modeled after Michael Pollan's In Defense of Food, his book argues we've been gaslit into a "zero-sun policy" the science does not actually support. You'll hear why melanoma is tied to intermittent sunburns rather than steady sun, the surprising 2024 research suggesting UVB may be protective while UVA is the real concern, and how office culture, window glass, and car windows may all be hidden pieces of the skin cancer puzzle. You'll also learn why the vitamin D supplement story is more complicated than the pills suggest, how sunlight lowers blood pressure through nitric oxide and lifts your mood through natural opioids, where sunscreen genuinely helps and where hats and shirts do better, what to make of the new sunscreen ingredient Bemotrizinol, and how a simple 30-day reset of your light exposure could transform your sleep.

BIG Peptide News (Must-Listen!): What Really Happened In Washington DC & A 7 Peptide Breakdown, With Dr. Matt Cook.

1 hr 13 min

Full show notes: https://bengreenfieldlife.com/peptides2026 In this episode with Dr. Matt Cook, recorded days after he returned from Washington, D.C., you'll get a breakdown of what just happened to peptides in the United States. You'll hear what the FDA's Pharmacy Compounding Advisory Committee actually voted on, why seven popular peptides were pulled two years ago, which six of the seven were just recommended for the bulk list, which one was left off, and what all of it means for your ability to get peptides legally from a pharmacy instead of the gray market. You'll also get a guided tour of the peptides themselves: BPC-157 for gut and tissue healing, KPV for inflammation, TB-500 for cell migration and wound repair, MOTS-c as an exercise mimetic, Semax for memory and learning, Epitalon for sleep and longevity, and DSIP for sleep. Dr. Cook explains why peptides behave so differently from ordinary drugs, walks through a safety review covering millions of doses, and shows how his company LifeOS pulls your labs, wearables, and genetics into one HIPAA-compliant place. And if you want to keep every peptide straight, Dr. Cook built a peptide cheat sheet covering what each one does, how to dose it, and where to source it.

The Breathwork-Cold Plunge Debate, When You *Shouldn’t* Do Wim Hof Breath & What Happens When 1 Million People Breathe Together

49 min

Full show notes: https://bengreenfieldlife.com/nickpodcast In this episode, you'll get a practical, plain-language tour of breathwork with Nick Sweeney, a breathwork coach who rebuilt his body with breath after a college bike accident left him unable to walk. You'll learn his Vortex Breath and the Fibonacci counting behind it, why slow breathing is really cardiovascular training that may predict how long you live, how to pair breath with fascia and mobility work, his routines for better sleep and for combining sauna, breath, and cold safely, where he lands on the cold plunge debate, why the air you breathe matters as much as how you breathe, and his "Billions Will Breathe" mission to get a million (and eventually a billion) people breathing in sync. Nick is the founder of Coherence, a breathwork app that trains your nervous system to improve deep and REM sleep, HRV, and stress resilience. After doctors told him his skiing career was over, he went from unable to walk to competing at U.S. Nationals within a year using breathwork, cold, and nervous system work, and today he leads a global movement to have people breathe together as one.

What Body Fat % Is The Most "Attractive" (& How Low is TOO Low), How To Shorten Your Gym Time, Is Creatine Bad For Your Kidneys & More! Solosode 503

49 min

Full Show Notes: https://bengreenfieldlife.com/503 In this solosode, you'll get the latest research on the questions I hear most: whether the peptide BPC 157 can cause cancer, the body fat percentages people rate most attractive for men and women (and how low is too low), how a "dad bod" before conception can affect your future kids' health, how "myo-reps" deliver the same strength and size gains in a fraction of your gym time, and whether creatine is bad for your kidneys. You'll hear why BPC 157's blood-vessel growth is not the same as the way cancer feeds a tumor and why healthy tissue has nothing to fear from it, how excess body fat quietly lowers testosterone, and why the most attractive body fat ranges line up almost perfectly with the ranges that support healthy testosterone, fertility, and a long life. You'll also walk away with the body fat targets actually worth aiming for, a simple way to shorten your time in the gym, and the creatine myths you can finally stop worrying about.

59 min

Full show notes: https://bengreenfieldlife.com/floridahunt In this episode, recorded at Lightsey Family Ranch in Venus, Florida, I'm joined by my sons River and Terran and repeat guest Adam Wenguer, founder of Element Health, for the first stop in a father-and-sons adventure project inspired by former Boundless guest Sahil Bloom's The 5 Types of Wealth. You'll hear the ethics and deeper meaning of hunting, why harvesting your own meat changes your relationship with food, and how to cook wild game so it actually tastes great. We also get into spearfishing and free diving, teaching kids breath work and comfort with heat and cold from a young age, and a grounded, plain-language look at cannabis and the endocannabinoid system, including how CBD, CBG, and CBN each work. Adam is a University of Florida graduate in applied physiology and kinesiology who spent more than a decade as a strength, conditioning, and health coach at a five-star wellness resort before founding Element Health in 2017.

Dynorphins, Heat Shock Proteins & The Healthiest, Hottest Sauna On The Planet, with Luke Chapman & Owen Buchanan

48 min

Full show notes: https://bengreenfieldlife.com/saunapodcast In this episode with Luke Chapman and Owen Buchanan, founders of Western Sol, you'll hear the story behind the custom sauna I recently had built in my backyard in Idaho, and the story behind the company itself, which started when a mold exposure in Hawaii sent Luke into daily sauna use. You'll gain insights into the actual science of heat shock proteins and dynorphins (the opioid peptides your body releases under heat stress), why most sauna wood is loaded with VOCs, and how thermally pressed aspen and spruce sourced from Estonia solves that problem entirely. We'll also touch on how Western Sol engineers oxygen-rich air recirculation, Himalayan salt therapy, and even full electrical grounding directly into the sauna floor, and you'll get a full walkthrough of what it costs to get a custom or prefabricated sauna built. Luke Chapman and Owen Buchanan are the founders of Western Sol, a custom and prefabricated sauna company based in Idaho. Both grew up around custom home construction in their family businesses before turning their focus toward building non-toxic, low-VOC saunas designed to support healing of the mind, body, and soul. They travel throughout Europe to source materials and study traditional sauna culture at its origin.

Why Do We Still Use 150-Year-Old Technology To Measure the #1 Killer of Humans Worldwide? The New Approach To Blood Pressure Measurement With Tom Moss.

1 hr 2 min

Full show notes: https://bengreenfieldlife.com/signalspodcast In this episode with Tom Moss, founder and CEO of Vital Signals, you'll hear how a near-fatal hypertensive crisis during a family vacation became the founding moment for a device that may finally solve the problem of getting accurate blood pressure readings in real life without a cuff. Tom explains why blood pressure is the single most important indicator of long-term cardiovascular health and yet one of the least accurately measured, what the cuff gets wrong, and how Vital Signals achieved the scientific breakthrough that other companies failed to crack: accurate, calibration-free blood pressure monitoring from a ring. You'll also hear about the interplay between sleep, stress, hormones, sauna, cold, and blood pressure, what the Signal Ring's data is already revealing about human arterial health, and where this technology could go over the next decade. Tom Moss is the founder and CEO of Vital Signals, building at the intersection of heart health, technology, and everyday behavior. After his experience with undiagnosed hypertension, he became focused on why some of the most critical health signals remain so difficult and often stressful to understand.

The Exciting FUTURE of AI-Based Medicine: How Patients Save Money & Doctors Save Time! with KJ Dhaliwal

58 min

Full show notes: https://bengreenfieldlife.com/lotus In this episode with KJ Dhaliwal of Lotus AI, you'll hear how translating his immigrant parents' doctor visits as a child and years spent bouncing through fragmented specialty care as a teenager after a disc herniation shaped his mission to give 100 million Americans free, world-class primary care using AI. KJ breaks down how Lotus AI pulls your entire medical history from every clinic and hospital you've ever visited in minutes, unifies it with your wearables and genetic data, and makes it available to both a conversational AI and a network of real licensed physicians who can diagnose you, prescribe treatment, and refer you to a specialist in under two minutes at any hour of the day.

KJ Dhaliwal is the founder and CEO of Lotus AI. Before Lotus, he co-founded the largest South Asian dating app, which he grew and sold.

The Potent Brain & Body Ketone Fuel You’ve Probably Never Heard Of: The Science Of R3HBG With Tecton’s Dr. Mike Chesne

56 min

Full show notes: https://bengreenfieldlife.com/tectonpodcast In this episode with Dr. Mike Chesne, founder of Tecton Ketones™, you'll hear how a traumatic brain injury sustained in combat led him from Army Special Forces medic to ketone biochemist, and why he eventually built what he believes is a meaningfully better exogenous ketone molecule than anything else currently on the market. We get into the real biochemical differences between ketone salts, ketone esters, and bioidentical beta-hydroxybutyrate, why the liver matters so much in how these molecules get metabolized, and a full walkthrough of Tecton's plant-based liposomal delivery system. You'll also hear about all four Tecton product formulations, the dual agonist effect ketones may have on hunger and fullness signaling, and the proposed mechanism behind why ketones may improve exercise recovery. Dr. Mike Chesne founded Tecton after a 25-year career in United States Army Special Operations.

How To Maintain Muscle On A GLP-1, Why Protein Stops Working As You Get Older, The Truth About Eating “Before Bedtime” & More! Solosode #502

1 hr 2 min

Full show notes: https://bengreenfieldlife.com/502 In this solosode, you'll explore how to make peace with tinnitus after acoustic trauma, including the half dozen different root causes that can drive it and the specific supplements and technologies with research behind them, why cardiovascular fitness itself seems to protect your hearing as you age, and whether tattoos are actually as risky as people think, from the heavy metals hiding in colored ink to what a major 2024 study found about tattoos and lymphoma risk. I also break down a new study showing you can get the same heat shock protein boost from heavy resistance training that you would normally only get from a sauna, why stacking a hard workout with a sauna session afterward may give you the best of both worlds, and take a closer look at a study making headlines for supposedly debunking the whole eating before bedtime rule, because the fine print tells a very different story than the headline does. Episode Sponsors: Xtendlife: Most vitamin E supplements contain only alpha-tocopherol, but the more compelling research points to tocotrienols for cardiovascular, brain, and healthy aging support.

Is Mitochondrial Transplantation The Longevity Intervention Of The Future (OLD Mice Climbing Up Walls Like YOUNG Mice!) With Tom Benson of Mitrix

50 min

Full show notes: https://bengreenfieldlife.com/mitrix In this episode with Tom Benson, founder and CEO of Mitrix, you'll hear why mitochondrial decline may be the actual root cause of aging rather than just a downstream symptom of it, and why most of the drugs developed so far to address it don't touch the real problem: damaged mitochondrial DNA. We discuss how Tom's company grows new, healthy mitochondria inside a bioreactor using banked stem cells, what mitochondrial transplantation actually looks like in real human cases already happening today, and the mouse study that gives this episode its name, in which severely aged mice receiving repeated mitochondrial injections were, according to the technicians running the experiment, climbing the walls of their cages by the very next day. Tom also touches on his original theory on the mitochondrial cycle of the body, how mitlets differ from naked mitochondria, and what his own MitoClock test reveals using nothing more than a urine sample. Tom Benson is the CEO and founder of Mitrix. He is a serial entrepreneur and scientist who has founded four successful software, hardware, and science startups. He has published dozens of articles and video lectures on mitochondrial science and cellular energetics, and developed original theories on the systemic transfer and distribution of mitochondria within higher organisms and how that affects health and lifespan.

1 hr 10 min

Full show notes: https://bengreenfieldlife.com/bretthurt In this episode with Brett Hurt, serial tech entrepreneur and author of Love Conquers Fear, you'll hear how he went from coding obsessively at seven to building one of the early internet's most popular games, surviving the dot-com bust, orchestrating two major exits, data.world to ServiceNow and Bazaarvoice's billion-dollar IPO, and experiencing a psychedelic awakening at 50 that redirected his entire life. You will also hear his vision for what an Age of Abundance looks like in practice, from solar energy and robotics to brain-computer interfaces and the role AI might play in solving problems like clean water, food security, and healthcare access in places like Chad, and why Brett believes the single most important variable in whether AI helps or hurts humanity is whether the people building it are operating from love or from fear. Brett Hurt is a tech entrepreneur and investor. He co-founded and led data.world, acquired by ServiceNow in July 2025, and previously co-founded Bazaarvoice and Coremetrics, acquired by IBM.

Could This ONE Simple Change Fix Your Sleep Forever?, Making Schools Healthy Again, and Why Your Air Filter Probably DOESN’T Work Right With Mike Feldstein.

1 hr 7 min

Full show notes: https://bengreenfieldlife.com/jaspr2026 In this replay episode, Mike Feldstein makes the case that clean air may be the single most overlooked variable in your health, sleep, and cognitive performance stack. Mike draws on firsthand experience from the LA wildfires (testing air, soil, and water after thousands of homes burned), revealing why most standard air purifiers, water tests, and insurance claims completely miss the real threat. You'll also discover how clean air has eliminated snoring and resolved sleep apnea symptoms in real households, what cognitive research on chess grandmasters reveals about pollution and decision-making, and how Mike is building Kindling Academy, a school designed from scratch around healthy air, light, toxin-free materials, and community wellness. Mike Feldstein is the founder of Jaspr, an air purifier company built on the conviction that most people are sleeping, working, and raising children in air that quietly undermines their health. With a background in wildfire restoration and indoor air quality consulting, he channeled years of hands-on field experience into creating the Jaspr Air Scrubber, a unit with a 4-pound filter roughly 10 times heavier than most competitors, built for real-world performance rather than lab benchmarks. Jaspr collaborates with building biologists, air scientists, and health practitioners to deliver practical guidance on indoor environments.

Eat 5 Pounds A Day of Broccoli OR Do *This* (+ Get Microplastics Out of Tissue Fast?!)

59 min

Full show notes: https://bengreenfieldlife.com/marapodcast In this episode, you'll hear the origin story of Mara Labs, a company built around sulforaphane, the active compound found in broccoli that has been studied across thousands of papers covering almost every major chronic disease, and why most people aren't actually getting it from their broccoli supplements. You will discover why the way your broccoli supplement is made determines whether any of it reaches your cells, what dose of the active compound moves the needle on inflammation, detox, and cellular defense, and how a single capsule compares to eating five pounds of adult broccoli a day. You'll also hear something that has not been discussed publicly before: a pilot study showing that this same compound can trigger your cells to release microplastics, those synthetic particles now found in human blood, lungs, and breast tissue, and push them out through your digestive system. David Roberts is the co-founder of Mara Labs. After his wife Mara was diagnosed with breast cancer passed away in 2017, David channeled his experience into building a supplement company grounded in clinical science rather than ingredient trends. Dr. John Gildea is Chief Science Officer and co-founder, with a PhD in molecular biology and over 20 years studying the Nrf2 pathway at the University of Virginia. Author of more than 60 peer-reviewed publications, he developed the stabilization method that made shelf-stable sulforaphane possible and has since led research on sulforaphane's effects on microplastics and cancer stem cells.

Could *This* Molecule Be the KEY To Reversing Immune Aging & “Supercharging” Your Mitochondria? With Dr. Anurag Singh

50 min

Full Show Notes: https://bengreenfieldlife.com/timelinereplay In this special replay episode with repeat guest Dr. Anurag Singh from Timeline Nutrition, you'll explore the science of cellular health and longevity, including why mitochondrial function affects everything from energy and muscle performance to cognitive clarity and how well you age. Dr. Singh explains how urolithin A, a postbiotic compound derived from foods like pomegranates and berries, activates mitophagy, the body's cellular clean-up system that clears out worn-out mitochondria and replaces them with new ones, and how clinical research shows it can support muscle strength, endurance, immune resilience, and cognitive function. You'll also hear how diet, gut health, exercise, sleep, and recovery work alongside urolithin A to build a stronger, more resilient physiology over time. Dr. Anurag Singh is Chief Medical Officer at Timeline Nutrition, with an M.D. in internal medicine and a Ph.D. in immunology. He has authored more than 50 scientific articles, been awarded over 20 patents, and led more than 50 randomized clinical trials. His decade of research on urolithin A has produced multiple clinically validated products bringing longevity science directly to consumers.

Light Engineering That Makes You Look YOUNGER (& Beauty Lasers Vs Face Masks!) With LYMA’s Lucy Goff

48 min

Full show notes: bengreenfieldlife.com/lymapodcast  In this episode with Lucy Goff, you'll hear how a near-fatal bout of septicemia after childbirth sent her on a decade-long search through the world's leading science institutions, and how that search led to LYMA, a company built around the conviction that damaging your skin to improve it is the wrong approach entirely. You'll discover why the collagen you get from ablative lasers, microneedling, and radiofrequency is scar collagen, how cold laser works by a completely different mechanism, and what a head-to-head gene expression study in human skin revealed when a cold laser was compared to an LED running ten times the power. Lucy Goff is a former journalist and luxury publicist who walked away from a successful career to change the wellness industry from the ground up. She launched the LYMA Supplement in 2018, followed by the LYMA Laser, the first FDA-cleared at-home clinical-grade laser. LYMA is now recognized as one of Fast Company's Most Innovative Beauty Companies, a King's Award for Enterprise winner, and one of the fastest-growing private companies in Britain.
