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.

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how well you function afterward, how he harvests your own cells mid-operation, and why going into surgery starving is outdated.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. Speak with your own physician or surgeon before implementing anything you hear. Episode Sponsors: JOYMODE: Boost your sexual performance, and do it naturally without nasty prescription drugs.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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).

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.

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.
