In this episode, Buck dives into the groundbreaking work of Dr. David Raubenheimer and Professor Stephen Simpson, renowned nutritional scientists from the University of Sydney. They unpack the "Geometric Framework for Nutrition," a holistic and visual approach that examines how nutrients interact to shape health and aging. From protein leverage to balancing macronutrients for longevity, this conversation challenges conventional calorie counting and offers profound insights into optimizing diet across the lifespan.

Buck and Prof Glen Jeffery dive deep into the science of red light therapy, revealing how it boosts mitochondrial function and potentially slows aging. He shares groundbreaking insights from clinical trials, showing how red light can recharge cellular energy and improve vision health. We get into practical tips on using red light therapy—where to get it, when to use it, and what to watch out for in devices.

Buck interviews Dr. Dennis Hughes, a concierge physician with a special interest in lipidology. They discuss the complexities of cholesterol, the importance of understanding lipid profiles, and the role of various lipoproteins in cardiovascular health. Dr. Hughes emphasizes the need for modern medicine to move beyond outdated notions of 'good' and 'bad' cholesterol, advocating for a more nuanced understanding of lipid management. The discussion also covers key lab tests, the significance of apolipoprotein B, and the future of pharmacotherapy in lipid management.

Dr. Diogo Barardo, Director of Research and Development at Novos, joins Buck to discuss Novos’ innovative approach to longevity supplements, unpacking the differences between biological and epigenetic aging and the impact of the Drug Age database. He details how Novos evaluates compounds for safety and efficacy, the unique ingredients in their flagship NovoScore, and the promising roles of lithium microdoses and NAD precursors. Their conversation also delves into the latest in longevity science, from the controversies around resveratrol to mitophagy’s role in cellular health, the complexities of supplement dosages, and the potential of aging biomarkers and AI-driven research for consumer longevity solutions.

Buck and Dr. Nathan Bryan delve into the pivotal role of nitric oxide in human physiology, with a particular focus on cardiovascular health and aging. Dr. Bryan breaks down the body’s nitric oxide production processes, how everyday lifestyle choices impact its levels, and what happens when there’s a deficiency. He also explores the surprising connection between oral hygiene and nitric oxide, the risks associated with proton pump inhibitors, and the promise of emerging products designed to boost nitric oxide levels. Additionally, Dr. Bryan addresses genetic factors such as MTHFR polymorphisms that can impact nitric oxide synthesis, shedding light on their broader implications for health and longevity.

Buck speaks to Dr. Torkil Færø, a Norwegian general practitioner, emergency physician, and seasoned traveler with Doctors Without Borders, to discuss the crucial relationship between stress, heart rate variability (HRV), and overall health. Dr. Færø delves into how HRV serves as a key indicator of our body’s autonomic nervous system balance, showing how lifestyle factors, particularly chronic stress, can undermine well-being. He highlights practical strategies, from breathwork to dietary adjustments, aimed at optimizing HRV and promoting long-term health.
