    Everything You Know About Calories Is Wrong | Dr. Robert Lustig

    What if one of the most basic ideas in nutrition — that a calorie is a calorie — is the wrong way to think about metabolic health? For decades, Robert Lustig has argued that obesity, diabetes and other chronic metabolic diseases cannot be understood through energy balance alone. His central argument: what happens to food after we eat it matters, and added sugar — particularly fructose — can disrupt metabolic function in ways calorie counting fails to capture. In this episode of Return on Health, hosts Niko Hems and Miguel Medina challenge Robert on how strong that case actually is. They discuss his research on sugar restriction, controlled feeding trials that appear to contradict some of his conclusions, food-industry influence on nutrition science, ultra-processed food, agricultural subsidies and the incentives shaping what we eat. The conversation also turns to Ozempic, Wegovy and other GLP-1 drugs. ━━━━👤 ABOUT THE GUEST━━━━━ Robert H. Lustig, MD, MSL is a pediatric endocrinologist and Professor Emeritus of Pediatrics at UCSF. He spent decades researching childhood obesity, diabetes and metabolic disease. His 2009 lecture “Sugar: The Bitter Truth” has been watched more than 25 million times on YouTube and made him one of the most prominent and debated voices in nutrition. He is also the author of Metabolical, Fat Chance, and The Hacking of the American Mind. ━━━━🎙️ ABOUT THE HOSTS━━━━ Niko Hems is Head of Strategy & Medical Communications at YEARS, a preventive medicine company using longitudinal and multi-modal health data to make prevention more personalized and data-driven. Miguel Medina is co-host of Return on Health, a podcast built around a simple idea: a system produces the outcomes it is incentivized to produce — so better health outcomes require better incentives. ━━━━⏱ CHAPTERS━━━━━ 00:00 Who Is Robert Lustig?00:52 What Is Metabolic Disease?04:02 Mitochondrial Dysfunction Explained09:11 What Does Metabolism Actually Mean?10:45 Is “A Calorie Is A Calorie” Wrong?15:35 Why Robert Thinks Fructose Damages Mitochondria17:08 What Happened When His Team Removed Added Sugar?22:49 Niko Challenges Robert On Contradictory Fructose Studies29:23 Does Food Industry Funding Distort Nutrition Research?33:10 How The Food Industry Shapes Science35:20 The Center To End Corporate Harm38:23 How Do We Fix The Food System?41:18 What Can Ordinary People Actually Do?44:50 Microplastics, PFAS & Other Metabolic Exposures48:02 Can We Feed 10 Billion People Without Ultra-Processed Food?51:47 The Most Underrated Metabolic Biomarker52:45 Why Robert Refuses To Share His Personal Diet53:14 What Foods Should People Eat More — And Less — Of?54:46 What Robert Lustig Changed His Mind About56:59 What Would He Change About US Food Policy?58:09 How Food Subsidies Shape What We Eat01:01:50 Robert Lustig On Ozempic, Wegovy & GLP-1 Drugs01:04:35 The Potential Downsides Of GLP-1s01:08:30 Why Robert Says We Still Have To Fix The Food01:09:35 What Should Change About Healthcare? ━━━━━💡 KEY QUESTIONS ANSWERED━━━━━ • Is “a calorie is a calorie” biologically misleading?• Why does Robert consider fructose different from glucose?• What happened when his team restricted sugar without reducing calories?• Why do some controlled feeding trials reach different conclusions?• Does food-industry funding distort nutrition research?• How much does ultra-processed food contribute to metabolic disease?• Is fasting insulin an underrated biomarker?• How do food subsidies influence what we eat?• Are Ozempic and Wegovy solving obesity or treating the symptom?• What concerns does Robert have about widespread GLP-1 use?• Why does he think healthcare should spend far more on prevention? ━━━━━━━━━━━━━━━ Connect with Robert: Website: https://robertlustig.com/LinkedIn: https://www.linkedin.com/in/robert-lustig-8904245/UCSF: https://profiles.ucsf.edu/robert.lustig

    The First Person to Live to 1,000 Is Already Alive? | Aubrey de Grey

    What if aging is less like an inevitable biological process.. and more like damage that can eventually be repaired? For more than two decades, Aubrey de Grey has argued that aging should be treated as a medical problem driven by the accumulation of molecular and cellular damage. His most famous idea, longevity escape velocity. In this episode of Return on Health, hosts Niko and Miguel challenge Aubrey on how realistic that vision actually is, what his latest mouse rejuvenation experiments can tell us about humans, why his first major study fell short of its ultimate goal, and what would have to happen before rejuvenation becomes real medicine. Aubrey also explains why he believes aging can be approached through repair, why combining interventions may matter more than testing them one by one, why current biological age clocks are still limited, what he thinks the Hallmarks of Aging get wrong, and why he believes the first person to live to 1,000 years has probably already been born. ━━━━👤 ABOUT THE GUEST━━━━━ Aubrey de Grey is a biomedical gerontologist and one of the most prominent voices in longevity science. He is the founder and President of the Longevity Escape Velocity Foundation, where his work focuses on developing and testing combinations of rejuvenation therapies aimed at repairing different forms of age-related damage. He is also known for developing the SENS framework and popularizing the concept of longevity escape velocity: the idea that sufficiently effective rejuvenation therapies could extend healthy life long enough for progressively better therapies to arrive. ━━━━🎙️ ABOUT THE HOSTS━━━━ Niko Hems is a longevity expert and Head of Growth at YEARS, a company building a longitudinal, multi-modal health dataset to make prevention personal and data-driven. Miguel Medina is co-host of Return on Health, a podcast built on a simple idea: a system always produces the outcomes it's incentivized to produce. ━━━━⏱ CHAPTERS━━━━━ 00:00 Is Aging Actually A Disease? 02:17 Aubrey's Latest Mouse Rejuvenation Study 08:23 What Actually Counts As Age-Related Damage? 13:59 Can Mouse Longevity Research Translate To Humans? 16:25 How Do We Measure Anti-Aging Effects In Humans? 20:36 Can The First Person To Live To 1,000 Already Be Alive? 23:18 Longevity Escape Velocity Explained 28:16 Did Aubrey's First Mouse Rejuvenation Study Work? 32:11 How Do You Choose Which Longevity Interventions To Combine? 37:37 SENS vs The Hallmarks Of Aging 43:32 What Has Aubrey Changed His Mind About? 45:39 What Should People Actually Do Today? 47:54 Why Longevity Research Struggles To Get Funded 53:32 Prevention vs Rejuvenation 55:35 What Aubrey Would Change About Science 57:16 The Strongest Argument That Aging Can Be Repaired 58:08 Aubrey's Personal Longevity Protocol 58:41 Are Biological Age Clocks Actually Useful? 01:00:18 How Should Healthcare Change? ━━━━━💡 KEY QUESTIONS ANSWERED━━━━━ • Is aging actually a disease? • What does Aubrey de Grey mean by accumulated biological damage? • Can age-related damage actually be repaired? • What is longevity escape velocity? • Could the first person to live to 1,000 already be alive? • What happened in Aubrey's first robust mouse rejuvenation experiment? • Why is he now testing a combination of eight interventions? • Can longevity results in mice realistically translate to humans? • How can we test rejuvenation therapies without waiting decades for mortality data? • What is the difference between the SENS framework and the Hallmarks of Aging? • Are biological age and epigenetic clocks reliable enough for clinical trials? • What has Aubrey changed his mind about after more than two decades? • Why does he think current research funding creates the wrong incentives? ━━━━━━━━━━━━━━━ Connect with Aubrey: Longevity Escape Velocity Foundation: https://www.levf.org/ X / Twitter: https://x.com/aubreydegrey LinkedIn: https://www.linkedin.com/in/aubrey-de-grey-24260b/

    Cancer Scientist: What Actually Causes Cancer? (The Internet Got It Wrong)

    What if one of the most popular ideas about cancer is simply wrong? For years, social media has promoted the idea that cancer is primarily a metabolic disease - one that can be starved, hacked, or even reversed through diet. But cancer geneticist Dr Moritz Przybilla argues that decades of genomic research tell a very different story. In this episode of Return on Health, hosts Niko Hems and Miguel Medina explore why cancer is fundamentally a disease of DNA, why aging remains its greatest risk factor, what the evidence really says about ketogenic diets and sugar, and where cancer research is genuinely moving next. Moritz also explains why most people misunderstand cancer prevention, why early detection may save far more lives than chasing miracle cures, how healthy tissues quietly accumulate mutations throughout life, and why the future of cancer medicine may lie in predicting risk decades before a tumor ever appears. ━━━━👤 ABOUT THE GUEST━━━━━ Dr. Moritz Jakob Przybylla is a cancer researcher at the Wellcome Sanger Institute in Cambridge. His research focuses on cancer genomics, early cancer evolution, and developing new approaches for cancer risk prediction, prevention, and early detection. Alongside his research, Moritz is passionate about making cancer science accessible and combating misinformation with evidence-based education. ━━━━🎙️ ABOUT THE HOSTS━━━━ Niko HemsNiko Hems is a longevity expert and Head of Growth at YEARS, a company building a longitudinal, multi-modal health dataset to make prevention personal and data-driven.

    You Can't Stop Aging! Here's What Actually Matters… | Prof. Suresh Rattan

    Most people think aging is a disease. Professor Suresh Rattan thinks that's one of the biggest misconceptions in modern medicine. The anti-aging industry has never been bigger. Every week there's a new supplement, a new biomarker, a new longevity protocol, or another promise that you can slow, reverse, or even cure aging. But after more than 40 years studying the biology of aging, Suresh has reached a very different conclusion. Aging isn't something to cure. It's something to understand. In this episode of Return on Health, hosts Niko Hems and Miguel Medina sit down with one of the world's leading biogerontologists to challenge everything we think we know about aging, longevity, and health. We explore why Suresh believes there are no genes programmed to make us age, why the anti-aging industry is selling false promises, what he really thinks about Bryan Johnson, David Sinclair, and longevity escape velocity, and why living well may matter far more than simply living longer. ━━━━━👤 ABOUT THE GUEST ━━━━━ Professor Suresh I.S. Rattan is one of the world's leading biogerontologists, with more than four decades of research into the biology of aging. He founded the Laboratory of Cellular Ageing at Aarhus University in Denmark, coined the term "gerontogenes", founded the journal Biogerontology, and has published hundreds of scientific papers exploring why we age and what healthy aging really means. His work challenges many of the assumptions driving today's longevity industry, arguing that aging is a natural consequence of life - not a disease to be cured. ━━━━━━🎙️ ABOUT THE HOSTS ━━━━━━ Niko Hems Niko Hems is a longevity expert and Head of Growth at YEARS, a company building a longitudinal, multi-modal health dataset to make prevention personal and data-driven.

    Longevity Expert: Everything We've Been Told About Living Longer Is Wrong

    Most people think longevity is about living longer. Dr. Jack Kreindler thinks that's exactly where we've gone wrong. The longevity industry has never been bigger. Every week there's a new supplement, a new biomarker, a new biohack, or a new promise that you can slow aging. But after more than 25 years working with elite athletes, founders, CEOs and patients facing life-threatening disease, Jack has reached a very different conclusion. The goal isn't to live longer. It's to stay fully alive for as long as possible. In this episode of Return on Health, hosts Niko Hems and Miguel Medina sit down with one of the world's leading physicians in preventive medicine and human performance to separate evidence from hype. We explore why Jack has become one of the biggest critics of the word longevity, what he really thinks about Bryan Johnson and David Sinclair, whether NAD boosters actually make sense, and why purpose, relationships and resilience may be more powerful than the latest biohack. ━━━━━👤 ABOUT THE GUEST━━━━━ Dr. Jack Kreindler is a physician, physiologist and entrepreneur specializing in preventive medicine, human performance and healthy aging.

    Best Selling Author: This Diet Will Betray You!

    Is the longevity supplement hype real - or are you wasting money? Bestselling author Bas Kast breaks down what actually works in nutrition, supplements, and slow aging. Most people don't suffer from a lack of health advice. They suffer from too much of it. One expert says eat more protein, the next says cut animal foods. One says supplements are useless, the next sells a 100-pill longevity stack - and all of it sounds convincing. In this episode of Return on Health, hosts Niko Hems and Miguel Medina sit down with Bas Kast - the science author whose book The Diet Compass (Der Ernährungskompass) sold over 1 million copies - to separate evidence from noise. We cover what still holds up in nutrition science, which supplements are worth taking (and which are pure marketing), why you are never the "average" person in a study, and Bas's new project SlowAger. ━━━━━━━━━━━━━━━ 👤 ABOUT THE GUEST ━━━━━━━━━━━━━━━ Bas Kast is a science journalist and bestselling author known for translating complex nutrition and longevity research for a general audience - without academic jargon or wellness hype.

    Functional Medicine MD: What 5,000+ Patients Taught Him About Root Cause Medicine

    Functional Medicine MD: What 5,000+ Patients Taught Him About Root Cause Medicine In this episode of Return on Health, we speak with Dr. Peter Martin, physician, former CNS pharmacology researcher, and founder of FunMed, one of Europe’s leading functional medicine clinics. Peter spent around 15 years in pharmacology research before his own burnout pushed him to look beyond the conventional model of symptom control. What started as a personal search for recovery became a data-driven clinical model built around root cause medicine, extensive biomarker testing, gut health, metabolism, and chronic disease prevention. We talk about what functional medicine actually means, why chronic disease often needs a different care model, and what Peter has learned from treating more than 5,000 patients. He explains why fasting insulin may be one of the most overlooked markers in modern healthcare, how low-grade inflammation is often connected to gut health, and why normal lab results do not always mean someone is truly healthy. We also get into the controversial parts: large biomarker panels, false positives, red meat, vegan diets, anti-nutrients, carnivore diets, and the weakness of much nutrition research. Peter also shares why he believes functional medicine could become part of the European healthcare system, especially if reimbursement shifts from visits and procedures toward actual health outcomes. This episode covers: What 5,000+ patients taught him Why fasting insulin is often missed How root cause medicine could change care Topics discussed: 00:00 Introduction 01:00 What FunMed does differently 02:00 Real-world data from 5,000+ patients 03:30 From CNS pharmacology to functional medicine 07:00 Root cause medicine vs symptom control 10:30 Precision health in Sweden and Germany 15:30 Why FunMed tests around 200 biomarkers 21:00 False positives and the problem with large panels 28:00 Fasting insulin and insulin resistance 31:00 Low-grade inflammation and gut health 35:30 Low-carb and ancestral nutrition 41:00 Vegan diets, nutrient deficiencies, and bio-individuality 49:30 Red meat, nutrition research, and epidemiology 56:00 Functional medicine and insurance coverage 59:00 Rapid fire: biomarkers, magnesium, carnivore diet, healthcare reform Guest Dr. Peter Martin Physician, former CNS pharmacology researcher, founder of FunMed, and one of the leading voices trying to bring functional medicine and precision health into European healthcare.

    Harvard MD: The Truth About Peptides And Longevity Medicine

    Harvard MD: The Peptide Boom Is Here.. But Is Medicine Ready? In this episode of Return on Health, Niko and Miguel speak with Dr. Anand Vinjamoori, Harvard Medical School and Harvard Business School trained physician, former founding Chief Medical Officer at Modern Age, advisor to Superpower, and founder of Next Generation Medicine. Together, they discuss why longevity medicine is booming while many companies still struggle to build sustainable businesses, why peptides may become one of the next major waves in health optimization, and why the future of biomarkers will likely require a much more individualized and data-driven approach. This episode covers: The peptide boom and why it mattersWhy longevity businesses often failWhat biomarkers can and cannot tell us Dr. Anand explains why the current medical evidence system may be too slow for the next generation of therapies, how real-world data and patient registries could help close the evidence gap, and why biomarkers should be used with nuance rather than treated as absolute truth. He also shares his view on overhyped interventions, the role of exercise, and the cultural differences between American optimization culture and European lifestyle rhythms.
