Can we slow the speed of aging? In this episode, Dr. Varun Dwaraka, Head of Bioinformatics at TruDiagnostic, walks us through through the science of measuring "biological age" using epigenetic markers, such as DNA methylation. We discuss how epigenetics (i.e. DNA methylation), may provide biomarkers of biological age, the rate at which aging occurs, and potentially early markers of disease. Dr. Dwaraka explains the distinctions between chronological and biological age, the development and refinement of epigenetic clocks, and the potential applications of these tools in aging interventions. The conversation also addresses the mechanisms of epigenetic regulation, the influence of lifestyle factors on biological age, and the future role of epigenetics in predicting and managing age-related diseases. Additionally, we examine the data science that underpins these clocks, their targeted outcomes, and a recent study published by Dr. Dwaraka and colleagues comparing aging biomarker outcomes in a vegan vs. omnivore diet intervention among twins.

Why do humans get cardiovascular disease and how can we prevent it? These are critical processes to understand for anyone who is interested in living a longer and healthier life. I'm very honored to talk with Dr. Tom Dayspring, a world-renowned clinical lipidologist and physician whose topic expertise is unparalleled. We discuss the underlying process of atherosclerosis & the formation of plaques, ApoB, methods to stabilize plaque, metabolic syndrome and insulin resistance, markers and the risk of atherosclerosis, LP-PLA2 & atherosclerosis, homocysteine and cardiac risk, genetic therapies for lipid disorders. We also discuss lifestyle interventions, including exercise, in managing lipid disorders and reducing cardiovascular risk.

In this episode, I had the pleasure of sitting down with Nicolas Verhoeven of Physionic. We focus our attention on metabolic health and, specifically, the energy-related, cellular, and nutritional mechanisms of insulin resistance. Nicolas reviews evidence pertaining to the reversal of insulin resistance and dietary clinical trials demonstrating remission of type 2 diabetes. Nicolas also highlights the synergistic effects of physical activity and dietary habits on insulin resistance, expanding our discussion into mitochondrial health. Finally, we explore importance of a nuanced conversation around autophagy and its role in health and disease prevention.
