Brian Kennedy is a renowned biologist, leader in aging research, & director of the Center for Healthy Longevity at the National University of Singapore. In this episode, Brian shares insights from ongoing human aging studies, including clinical trials of rapamycin & how dosing strategies, timing, & exercise may influence outcomes. He presents two key models of aging—one as a linear accumulation of biological decline & the other as an exponential rise in mortality risk—& explains why traditional models of aging fall short. He also explains why most current aging biomarkers lack clinical utility & describes how his team is working to develop a more actionable biological clock. Additional topics include the potential of compounds like alpha-ketoglutarate, urolithin A, & NAD boosters, along with how lifestyle interventions—such as VO2 max training, strength building, & the use of GLP-1 & SGLT2 drugs—may contribute to longer, healthier lives.
