Special Announcement: Will YOU Be The Next BenGreenfieldFitness Podcast Host?

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.

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

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.

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

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).
