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

    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

    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

    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

    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

    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

    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

    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. Mention Ben's name on your free breakthrough call with Energized Health for 40% off the 88-day program. Episode Sponsors: BIOptimizers Magnesium Breakthrough: Most magnesium supplements give you one or two forms.

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

    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.
