Matt Kaeberlein is globally recognized for his research on the biology of aging and is a previous guest on The Drive. In this episode, Matt defines aging, the relationship between aging, chronic inflammation, and the immune system, and talks extensively about the most exciting molecules for extending lifespan. He discusses the current state of the literature of testing rapamycin (and rapalogs) in animals and humans, including Matt’s Dog Aging Project, and provides insights into how we can improve future trials by conceptualizing risk, choosing better endpoints, and working with regulators to approve such trials. He also examines the connection between aging and periodontal disease, biomarkers of aging, and epigenetic clocks. Finally, they explore some of the biological pathways involved in aging, including mTOR and its complexes, sirtuins, NAD, and NAD precursors.

About:
The Peter Attia Drive is a weekly, ultra-deep-dive podcast focusing on maximizing health, longevity, critical thinking…and a few other things. With over 30 million episodes downloaded, it features topics including fasting, ketosis, Alzheimer’s disease, cancer, mental health, and much more.
Peter is a physician focusing on the applied science of longevity. His practice deals extensively with nutritional interventions, exercise physiology, sleep physiology, emotional and mental health, and pharmacology to increase lifespan (delay the onset of chronic disease), while simultaneously improving healthspan (quality of life).
