Internal medicine physician and insulin-resistance specialist Dr. Annette Bosworth explains why she believes routinely generating ketones is central to preventing and reversing many chronic conditions. She discusses insulin's role in aging and disease, the practical steps of her "keto continuum" approach, measurement of glucose and ketones, and tools like sardine fasts and exogenous ketones to break through insulin resistance. She also shares case studies from her practice, the story of using a ketogenic diet alongside her mother's cancer care, and her own legal and political ordeal that tested her faith and resilience.
The episode segment critiques the simplistic 'calories in, calories out' model of weight loss by explaining how the body adapts its basal metabolic rate to caloric restriction. The guest emphasizes the central role of hormones-especially insulin-in determining whether the body stores or burns fat, arguing that food is an instruction to the body, not just a source of calories. They discuss intermittent fasting, snacking patterns, exercise, and the concept of breakfast as tools or factors that influence hormonal balance and long-term weight regulation.
Andrew Huberman and Dr. David Sinclair discuss aging as a disease, the role of the epigenome and information loss in driving aging, and how these processes connect to visible signs of aging and age-related diseases. They explore how fasting, blood sugar control, growth hormone, amino acids like leucine, exercise, and compounds such as NMN influence key longevity pathways including sirtuins, mTOR, and NAD. The conversation also covers iron and senescent cells, biomarkers such as CRP and HbA1c, fertility and reproductive aging in animal models, and the broader concept that aspects of aging can potentially be slowed or partially reversed.
The host and four women's health experts explore how female physiology, hormones, and life stages change the way women should approach exercise, nutrition, fasting, recovery, and sleep. They explain why most fitness and medical research based on men fails women, detail how the menstrual cycle and perimenopause affect training and metabolism, and outline practical protocols for strength training, cardio, bone health, and weight management. The conversation also addresses fertility, energy availability, environmental toxins, supplements, and the need for women to advocate for their own health throughout life.
The host convenes four female health experts from exercise physiology, fertility, OB/GYN menopause care, and orthopedics to discuss women's hormonal health across the lifespan. They cover research bias against women, differences between male and female physiology, menstrual cycles as a vital sign, PCOS and endometriosis, contraception, fertility planning, perimenopause and menopause, and the role of lifestyle and hormone therapy in long-term health. Throughout, they emphasize that missing or irregular periods, chronic inflammation, and insulin resistance are early warning signs and that women can and should advocate for better-informed care.
Cardiologist Pradip Jamnadas explains how modern lifestyles drive heart disease through insulin resistance, visceral fat, chronic inflammation, and hidden factors like gut dysfunction, toxins, and mold. He describes how fasting, time‑restricted eating, targeted exercise, and gut repair can reduce visceral fat, lower inflammation, improve vascular health, and rebalance the autonomic nervous system. The conversation also covers LDL particle quality, the limitations and side effects of statins, practical diet guidance, vagus nerve "hacks", and his personal reflections on mortality and living in the present moment.
