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

    Fertility, Sperm Health, and Nutrition Before and During Pregnancy | Dr Federica Amati
    Jul 13 2026
    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

    Can You Reverse Heart Disease? What My Plaque Scans Showed | Dr Campbell Rogers
    Jul 6 2026
    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

    Reversing Artery Plaque: 8 Supplements Ranked by the Evidence | Simon Hill, MSc
    Jun 29 2026
    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. If you are enjoying the series, the simplest way to help is to leave a quick rating and review on Apple Podcasts, and to share this episode with someone whose heart health you care about. Can Supplements Actually Reverse Arterial Plaque? (00:00) EVAPORATE Trial: High-Dose EPA Reversed Plaque by 9% (02:09) Why Pure EPA Outperforms Standard Fish Oil (07:22) JELIS to REDUCE-IT: EPA Cuts Cardiac Events by 25% (10:10) REDUCE-IT Controversy and RESPECT-EPA 2024 (13:47) VITAL Trial: Omega-3 for Healthy Adults + 2026 Lp(a) Data (16:51) Aged Garlic Extract: 3 Trials on Plaque and Calcification (20:09) Vitamin K2: Does Redirecting Calcium Lower Heart Risk? (23:17) Niacin Failed: Why Raising HDL Didn't Save Lives (27:50) CoQ10: Promising Mechanism, No Plaque Imaging Proof (33:18) Berberine: The Gut Pathway No Other Supplement Uses (38:21) Nattokinase: One Study Says 36% Drop, One Says Zero (41:16) Pomegranate Extract: Strong Animal Data, Weak Human Trials (49:16) Which Supplements Can Actually Reverse Atherosclerosis?

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

    How to Lose Weight and Fix Your Metabolism in 2026 | Dr Mauricio Gonzalez
    Jun 22 2026
    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.

  • Evidence-Based Exercise in Pregnancy and Postpartum | Dr Margie Davenport

    Evidence-Based Exercise in Pregnancy and Postpartum | Dr Margie Davenport
    Jun 15 2026
    In this episode, exercise physiologist Dr Margie Davenport walks me through what the evidence actually shows about exercise during pregnancy and the postpartum period. Margie chaired the 2019 Canadian Guideline for Physical Activity throughout Pregnancy, the 2025 Canadian postpartum guideline, and the upcoming International Olympic Committee consensus statement on athletes through pregnancy and postpartum. We cover where the 140 bpm rule came from, the scale of the benefits at the population level, what direct fetal monitoring during HIIT and heavy lifting really shows, the new postpartum data, and why so many of the historical prohibitions do not survive contact with the data. What we cover: Where the 1985 "stay below 140 bpm" rule came from, and why it has long outlived its evidence Around 40 percent fewer cases of preeclampsia and gestational diabetes, and around 67 percent fewer cases of depression during pregnancy HIIT, heavy resistance training, and what fetal monitoring shows The 51 percent reduction in complications among women who kept lifting heavy Postpartum: the six-week myth, breastfeeding and injury risk, and a 45 percent reduction in postpartum depression The short list of actual "don'ts": scuba diving, and a few situational cautions The paradigm shift from prohibition to shared decision-making If this episode is useful, please leave a rating and review on Apple Podcasts or Spotify, and share it with someone in your life who is trying to make sense of conflicting advice.

  • Nutrition for satiety and weight loss | Dr Federica Amati

    Nutrition for satiety and weight loss | Dr Federica Amati
    Jun 9 2026
    GLP-1 medications are now part of the mainstream conversation, but the biology of appetite and satiety, the system these drugs operate within, gets far less attention than the drugs themselves. In this episode, I sit down with Dr Federica Amati, Head Nutritionist at ZOE and author of the new book The Appetite Reset, to explore what's actually happening in the gut and brain when appetite signals do their job, and what that means for everyone, on or off medication. Federica brings a rare combination of pharmacology, clinical nutrition, and public health expertise to a subject that rarely receives this level of nuance. This is a conversation about understanding your biology well enough to work with it. What we cover: How GLP-1 works naturally in the body, why the natural peptide lasts minutes while the drug version lasts days, and why this matters for anyone using or considering these medications The three types of hunger (hedonic, homeostatic, and microbiota-driven) and how to tell them apart in practice Why GLP-1 supplements don't replicate what the medications do "Prehab" before starting medication: gut microbiome diversity, fibre intake, and nutrient status as the foundation Why the 30g daily fibre target doesn't drop when calorie intake does on medication Protein targets of 1.2 to 1.6g per kilogram and resistance training three times a week as the most critical protective interventions for muscle and bone health The science on shame, weight stigma, and why treating obesity as a lifestyle choice is both inaccurate and actively harmful If this episode was useful, a review on Apple Podcasts or a follow on Spotify makes a genuine difference. To connect with Dr Federica Amati, follow her on Instagram at ⁠instagram.com/dr.fede.amati⁠ or explore her work through ZOE at zoe.com⁠. Her new book, The Appetite Reset⁠, will be released on June 25 and is available to pre-order now. Intro (00:00) Why Everyone Needs to Understand Appetite Biology (01:14) How Dr. Federica Amati Became a Nutrition Expert (03:06) Why GLP-1 Drugs Are Different From Any Supplement (11:29) The Gila Monster That Led to Ozempic (17:44) What Is Food Noise and Why It Controls You (20:20) Why Willpower Isn't the Problem: Genetics and Epigenetics (24:06) How GLP-1s Change Your Relationship With Food and Joy (30:54) Lowest Effective Dose: Why More Isn't Better (34:08) The Muscle Loss Risk Nobody Warns You About (39:34) Microdosing GLP-1s: Does It Work or Is It Dangerous (41:59) The Three Types of Hunger and How to Tell Them Apart (44:51) How Your Gut Microbes Drive Cravings and Leptin Resistance (50:17) Why Calories Alone Don't Explain Appetite (58:07) How to Manage Food Noise Without a GLP-1 (01:04:46) Prehab Before GLP-1s (01:11:09) The Fiber, Fat, and Gut Prep Protocol for GLP-1 Users (01:13:56) What Clinical Trials Actually Include That Real-World Use Doesn't (01:21:41) Do You Need Supplements on a GLP-1?

  • The Surgeon Defending Statins, GLP-1s, and Ancel Keys | Dr Terry Simpson

    The Surgeon Defending Statins, GLP-1s, and Ancel Keys | Dr Terry Simpson
    Jun 1 2026
    In this episode, I sit down with bariatric surgeon and science communicator Dr Terry Simpson for a wide-ranging conversation about health misinformation, GLP-1 medications, statins, ApoB, the Mediterranean diet, and the loud contrarians who dominate social media. Terry has familial hypercholesterolemia, a family history of premature cardiovascular disease, and lost 50 pounds on tirzepatide, all of which give him unusual personal stakes in these debates. What we cover: How to think about uncertainty in science, and Terry's heuristic for spotting misinformation The Gila monster origin story of GLP-1 medications, and the difference between native and pharmacological GLP-1 What food noise actually is, and Terry's own experience on tirzepatide His personal case for statins, an LDL of 190 brought into the 40s, and an ApoB in the 40s A defence of Ancel Keys and the Mediterranean diet Where the carnivore, anti-statin, seed oil, and nattokinase narratives fall apart Compounded GLP-1s, peptide deregulation, and why the FDA still matters If you find this episode useful, please leave a rating and review on Apple Podcasts or Spotify and share it with someone who might benefit.
