Peter Attia explains how he structures his weekly training to prioritize longevity, balancing resistance work, zone 2 cardio, and VO2 max training while minimizing injury risk. He details rep ranges for strength, hypertrophy, and endurance, his specific warm-up approach using dynamic neuromuscular stabilization and jumping, and why muscle mass, grip strength, and power are crucial for healthy aging. The conversation also covers glucose metabolism, the dangers of falls in older age, the role of the nervous system in flexibility, and a simple three-day resistance training split.
Dr. Robert Lustig explains how dopamine-driven behaviors and ultra-processed food, especially sugar, can create a "hostage brain" by rewiring reward pathways and degrading metabolic and brain health. He details mechanisms linking sugar, artificial sweeteners, mitochondrial dysfunction, and reactive oxygen species to Alzheimer's, cancer, depression, and other chronic diseases, while contrasting environmental versus genetic risk. The conversation also covers GLP-1 weight-loss drugs, vaccines and public health communication, loneliness, serotonin and oxytocin, practical strategies to reduce sugar and ultra-processed food, and emerging research on psychedelics and brain rewiring.
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.
