    The Fertility Test Most Men Are Never Offered | Dr Michael Eisenberg and Dr Natalie Crawford

    About one in seven couples are unable to conceive after a year of trying, and roughly half of those cases involve a male contribution. Yet in a quarter to a third of them, the man is never properly evaluated. In this episode I sit down with Dr Michael Eisenberg, a urologist and Director of Male Reproductive Health at Stanford University, and Dr Natalie Crawford, a reproductive endocrinologist and co-founder of Fora Fertility in Austin, Texas. This is the comprehensive male fertility resource I went looking for and couldn't find, and I have a personal stake in it. What surprised me most is that sperm health appears to be about much more than conception. It tracks with metabolic health, immune health, pregnancy outcomes, and in one Danish cohort, with age of death decades later. What We Cover What a semen analysis measures, and why ejaculating normally tells you nothing Semen quality as a sixth vital sign, and the Danish study linking it to lifespan Testosterone therapy, why it functions as a contraceptive, and how long recovery takes Whether sperm counts are really declining, and the likely drivers Cannabis, alcohol, heat, cycling, sleep, and body weight Total motile sperm count, DNA fragmentation, and what to ask your lab for Paternal age, sperm freezing, and timing your decisions Sperm turn over roughly every three months, which makes this one of the most movable metrics in health. Whichever stage of life you're at, this conversation is worth your time. To connect with Dr Michael Eisenberg, find him on Instagram or LinkedIn. To connect with Dr Natalie Crawford, you can find her book The Fertility Formula at nataliecrawfordmd.com/book, listen to her podcast As a Woman, or follow her on Instagram, TikTok, YouTube, and LinkedIn.

    Superagers, statins, the latest cholesterol pill and the truth about heart disease risk | Dr Terry Simpson

    Dr Terry Simpson is back, and we go deep on the science of protecting your heart and brain for the long run. He is a surgeon and one of the clearest voices online for separating solid evidence from confident hype, and in this conversation we tackle everything from new cholesterol-lowering drugs to gene editing, cognitive ageing, and the lean mass hyperresponder debate. Along the way we get a few things off our chests about the misinformation that spreads faster than the careful answer ever can. What We Cover Why healthy ageing brains owe more to lifestyle than to genetics How PCSK9 inhibitors work, and why plaque is more like geology than plumbing Gene editing for cholesterol and functional cures for type 1 diabetes The lean mass hyperresponder debate and what the Keto-CTA re-analysis shows Why colorectal cancer is rising in younger adults The 2026 dyslipidemia guidelines and why you should test your Lp(a) once This is a grounded, evidence-first conversation, and I hope it helps you feel clearer and more confident about the decisions that actually move the needle.

    The Science of Metabolic Flexibility, Zone 2, and Reversing Diabetes | A Masterclass

    Metabolic dysfunction rarely announces itself. We tend to think of metabolic health as a line you cross the day you are diagnosed with type 2 diabetes, but the decay usually begins years earlier, at the level of the cell. In this masterclass I bring together Dr Iñigo San Millán, Dr Alan Flanagan, Dr Kevin Hall, Dr Robert Eckel, Professor Roy Taylor, and Dr Christos Mantzoros to explain what metabolic flexibility is, why your mitochondria sit at the centre of it, and what you can actually do about it. What We Cover Why lactate is a fuel and a signal, not a waste product, and our best non-invasive window into mitochondrial function Whether a calorie really is a calorie, and what the controlled chamber studies found The twin cycle hypothesis, and why type 2 diabetes is more reversible than we were taught The personal fat threshold, and why a normal BMI can still hide a problem Whether sugar or saturated fat does more to drive fat in the liver Why Zone 2 earns its reputation, and how much of it you actually need Metabolic health is not fixed, and it is rarely too late to move in a better direction. I hope this conversation gives you a clearer picture of what is happening beneath the surface, and a few levers you can start pulling today. To learn more from the experts featured in this masterclass, you can follow Dr Iñigo San Millán on Instagram and Twitter, explore Professor Roy Taylor's work on type 2 diabetes remission at Newcastle University, read more from Dr Kevin Hall at kevinhallphd.com or on LinkedIn, and find Dr Alan Flanagan on Instagram and through Alinea Nutrition. The masterclass also features insights from Dr Robert Eckel and Dr Christos Mantzoros. If you are enjoying The Proof, please take a moment to rate and review the show on Apple Podcasts.

    New Science of Weight Loss | A Masterclass

    GLP-1 medications are transforming obesity treatment, but they're only one piece of the puzzle. In this masterclass, I bring together insights from Dr Terry Simpson, Dr Federica Amati, Dr Mauricio Gonzalez, Dr Christos Mantzoros, and Dr Stephan Guyenet to explain how these medications work, why "food noise" matters, and what it really takes to improve long-term metabolic health. What We Cover How GLP-1 medications regulate appetite and food noise Why obesity is more complex than willpower Semaglutide vs tirzepatide and newer medications Nutrition and resistance training while taking GLP-1s The role of fibre, protein, and Mediterranean-style eating Common misconceptions and side effects I hope this episode helps you better understand both the promise and the limitations of GLP-1 medications, while highlighting the importance of lifestyle alongside any medical treatment.

    Fertility, Sperm Health, and Nutrition Before and During Pregnancy | Dr Federica Amati

    We tend to treat pregnancy as the starting line for a child's health. In this episode, Dr Federica Amati, Head Nutritionist at ZOE, makes the evidence-based case that the window opens earlier, in the months before conception, and that it shapes fertility and lifelong health in ways most of us were never told. What I valued most is her balance. The science is striking, but she frames it as information to act on rather than a reason for guilt, and she is honest about how much sits with environment and policy rather than individual choice. What we cover: Why the first 1,000 days may be the longevity lever almost no one talks about How a father's metabolic health links to his child's brain, and a mother's to their metabolism The 90-day preconception window, and what both partners can do What the decline in sperm counts really means for individuals GLP-1 medications, fertility, and a contraception detail too few people hear Protein, eggs, soy, and choosing a prenatal supplement, myths included Whether you are planning a pregnancy, supporting a partner, or simply curious about how much of our health is set before birth, I think this one will stay with you. To connect with Dr Federica Amati, follow her on Instagram and explore her work at ZOE. If you enjoy the show, please take a moment to rate and review The Proof on Apple Podcasts or Spotify.

    Can You Reverse Heart Disease? What My Plaque Scans Showed | Dr Campbell Rogers

    In late 2024 a CT scan revealed a small amount of soft plaque in my arteries. Sixteen months later I scanned again, and my plaque volume had dropped by around forty percent. In this episode I ask the cardiologist behind the technology whether a result like that can really be trusted. Dr Campbell Rogers is an interventional cardiologist, a former Harvard faculty member who ran the cath lab at Brigham and Women's Hospital, and now Chief Medical Officer at Heartflow. What we cover: The difference between a calcium score, a CT coronary angiogram, and AI plaque analysis Why a calcium score of zero does not mean you are free of disease What my own scans showed, and why Campbell believes the result Soft versus calcified plaque, and why calcification can be a sign of stabilisation Treating the plaque you can see rather than just an ApoB number Who should consider getting scanned, and the honest trade-offs This is a conversation about seeing a disease we used to only guess at, held with the right amount of scientific humility. If you want to understand your own heart health, I think it is well worth your time. If you enjoy the show, please take a moment to rate and review The Proof on Apple Podcasts or Spotify.

    Reversing Artery Plaque: 8 Supplements Ranked by the Evidence | Simon Hill, MSc

    Can a supplement actually reverse the plaque in your arteries, or only slow it down? It is the question I am asked most, and after a 2024 scan revealed early plaque in my own left anterior descending artery, it became a personal one too. This is part two of my three-part series on reversing atherosclerosis. In this solo episode I work through eight of the most popular supplements and rank them by the strength of the human evidence, not the strength of the marketing. What we cover: Why pure EPA has by far the strongest evidence for regressing plaque, and what EVAPORATE, CHERRY, JELIS, and REDUCE-IT showed The REDUCE-IT versus STRENGTH debate, and why the form of omega-3 may matter as much as the dose Aged garlic extract and vitamin K2: what the imaging and calcification data suggest Niacin and the biomarker trap: raising "good" cholesterol without lowering risk Where CoQ10, berberine, nattokinase, and pomegranate extract really sit, plus a fact-check of a popular nattokinase claim My own plan after that scan, and a preview of part three on the pharmaceuticals Only one of these eight has strong evidence behind it, and even then it is a prescription rather than a tub from the supplement aisle. Supplements can be useful additions, but never a replacement for the proven basics. You can see exactly what I take over at my personal supplement stack.

    How to Lose Weight and Fix Your Metabolism in 2026 | Dr Mauricio Gonzalez

    For decades we have treated the number on the scale as the goal of metabolic health. Dr Mauricio Gonzalez, a triple board-certified physician and endocrinology fellow practising in New York, makes the case that we have been measuring the wrong thing. In this conversation we explore why liver fat, not body weight, is becoming the real target, what the latest weight-loss medications can and cannot do, and how to cut through the hype and dogma that surround this field. What we cover: Why isolated blood tests and blood pressure readings tell you very little The myth that GLP-1 medications are "the easy way out" Why liver fat may matter more than body weight How diabetes clinics now remove medications instead of adding them Which supplements earn their place, and which Mauricio has cooled on The minimum effective dose for exercise, and knowing when "enough" is enough A grounded, practical conversation with a doctor who meets people where they are.
