Can you meaningfully improve type 2 diabetes without losing weight? Dr Nicola Guess, registered dietitian and Senior Research Fellow at the University of Oxford, says the evidence is clear: a higher-protein, lower-carbohydrate diet can lower post-meal glucose by more than medication, no weight loss required. We also tackle the noisier end of the blood sugar conversation: glucose spikes, fruit…
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, Director of Male Reproductive Health at Stanford University and Chief Medical Advisor of SwimClub, and Dr Natalie Crawford,…
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…
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…
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…
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…
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…
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…
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…
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…
