Longevity expert Dr Florence Comite joins me to explain why testosterone, not estrogen, drives body composition and ageing in midlife women. Decline isn't inevitable - it's programmable. She unpacks why testosterone (which women carry in larger amounts than estrogen) drives muscle, visceral fat and brain fog from your 30s on, why only a third of us should fast, and the five biomarkers - fasting glucose, HbA1c, fasting insulin, cholesterol risk ratio and free testosterone - that predict where your healthspan is headed and how to change it. WHAT YOU'LL LEARN Why women carry more circulating testosterone than estrogen, and what its decline does to muscle, visceral fat and cognition from your 30s What "I don't feel like myself anymore" is actually signalling beneath the surface How cortisol quietly drives the anxiety-out-of-nowhere, the 2am wake-ups and the stubborn weight around your middle Why only a third of women should fast, and the 3-hour glucose test that tells you which third you're in What the five non-negotiable biomarkers reveal about where your healthspan is headed TIMESTAMPS 00:00 Intro: Why You Don't Feel Like Yourself After 35 - Peak Health, Testosterone Decline & the 30s Shift 05:52 - Perimenopause, Cortisol & Anxiety Out of Nowhere: Belly Fat, Sleep and the Caregiver Load 13:28 - Wearables, CGM & the Fasting Third/Third/Third: Measuring How Your Body Really Ages 20:11 - Who Should Actually Fast: The 3-Hour Glucose Test, Protein at Every Meal & the Oatmeal Trap 27:00 - Testosterone for Body Composition & Energy: UK Access, the 2024 Study & Protein for Muscle 33:46 - The 5 Biomarkers That Predict How You Age - Plus the 7 Patterns of Health Decline 39:37 - Decade by Decade for Women vs Men: Bone Loss, Osteoporosis, Andropause & Owning Your Healthspan VALUABLE RESOURCES - Invincible (Dr Comite's new book): https://www.penguin.co.uk/books/475986/invincible-by-comite-florence/9781529977066 - Dr Florence Comite's website: https://www.comitemd.com/ - Follow Dr Comite on Instagram: https://www.instagram.com/drflorencecomite/ AlgaeCal Plus*‡: Science-backed supplements designed to support healthy aging👉 http://algaecal.info/angela-foster *These statements have not been evaluated by the Food and Drug Administration.
