Perimenopause Is the Inflection Point Breaking Women's Health — Dr. Mayoni Gooneratne

What if the most dangerous metabolic inflection point in a woman's entire life is the one we've been taught to simply endure?In this episode of Health Longevity Secrets, Robert Lufkin MD sits down with Dr. Mayoni Gooneratne — a London-trained former NHS colorectal and pelvic floor surgeon, now the founder of Human Health and vice-chair of the British College of Functional Medicine. Dr. Mayoni walks us through why she walked away from the operating theater and how perimenopause — not menopause — is the real window where metabolic disease, cognitive decline, and cardiovascular risk are either quietly programmed in or actively reversed.CHAPTERS:00:00 — Introduction01:47 — From NHS Surgeon to Functional Medicine Founder06:53 — Dr. Mayoni's Own Perimenopause Story07:12 — Her Mother's Menopause-to-Diabetes Cascade08:43 — The Cortisol Trap: Three Kids Under Three10:39 — The Surgical Mentor Who Changed Everything12:27 — What Functional Medicine Actually Is12:52 — Root Cause vs "Treat and Street" Medicine18:08 — The Timeline Aha Moment Patients Never Forget21:09 — The Human Health Roadmap: Gut, Hormones, Mitochondria24:19 — The Thrive Program for Perimenopause25:42 — Body Fit: 16-Week Ketogenic Metabolic Reset29:14 — Why You Shouldn't Stay in Ketosis Long-Term33:20 — Why Normal Vitamin D Isn't Optimal Vitamin D35:02 — Where AI Fits in Functional Medicine36:03 — The Ovarian Age Clock Every Woman Should Know About37:56 — The NHS-Private Divide in Chronic Disease40:09 — Eat Better, Move Better, Sleep Better42:18 — Where to Find Dr. MayoniKEY TAKEAWAYS:• Perimenopause — not menopause — is the real metabolic inflection point for women• Loss of estrogen can trigger type 2 diabetes and cardiovascular disease within months• Chronic high-cortisol lives prime the perimenopause crash• "Normal" vitamin D isn't optimal vitamin D — aim for ~100• Nutritional ketosis works as a 16-week reset, not a permanent lifestyle• New ovarian age clocks let women plan for reproductive aging precisely• Pregnancy glucose tolerance results preview perimenopausal metabolic riskSTUDIES & SOURCES MENTIONED:• Dr. Mayoni Gooneratne — Human Health clinic• British College of Functional Medicine• Institute for Functional Medicine• Future Patient digital magazine and congress• Ovarian age clocks / reproductive aging research (Nature)• North American Menopause Society — hormone therapy position statement⭐ Enjoying the show?
