In this “Ask Me Anything” (AMA) episode, Peter explains how to evaluate sugar and its substitutes in the context of health. Peter explores the role of sweeteners in three common use-cases – beverages, protein supplements, and sweet treats – and breaks down how our evolutionary craving for sweetness now clashes with today’s food environment. He examines whether sugar is uniquely fattening, the hormonal effects of sugar consumption, and the significance of timing in sugar intake. The episode compares natural versus refined sugars, sugar in beverages versus in solid foods, and the...

Charles Duhigg is a Pulitzer Prize-winning journalist and best-selling author known for distilling complex neuroscience and psychology into practical strategies for behavior change, performance, and decision-making. In this episode, Charles explores the neuroscience behind habit formation, including how cue-routine-reward loops drive nearly half of our daily actions and why positive reinforcement is far more effective than punishment. He explains how institutions like the military and Alcoholics Anonymous engineer environments to change behavior at scale, as well as discussing the limits of...

Eric Verdin is a physician-scientist and the CEO of the Buck Institute for Research on Aging whose career has centered on understanding how epigenetics, metabolism, and the immune system influence the aging process. In this episode, Eric traces his scientific journey from studying viruses and histone deacetylases (HDACs) to leading aging research at the Buck Institute, offering insights into how aging impairs immune and nervous system function—including thymic shrinkage, chronic inflammation, and reduced vaccine response—and how these changes impact lifespan. He explores the metabolic...

Brian Kennedy is a renowned biologist, leader in aging research, and 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 and how dosing strategies, timing, and exercise may influence outcomes. He presents two key models of aging—one as a linear accumulation of biological decline and the other as an exponential rise in mortality risk—and explains why traditional models of aging fall short. He also explains why most current aging biomarkers lack...

In this “Ask Me Anything” (AMA) episode, Peter addresses frequently requested topics, including brain health, exercise programming, and body composition. He explores the factors that influence dementia risk—including metabolic health, fitness, sleep, hearing, cholesterol levels, and more. He explains how to implement zone 2 training and VO₂ max intervals for cardiovascular fitness and also covers how to combine cardio modalities, how to stay in zone 2, and special considerations for women. Peter highlights the benefits of light movement after meals and offers strength training tips...

In this episode from July 2022, Peter dives deep into the topic of bone health and explains why this is an important topic for everyone, from children to the elderly. He begins with an overview of bone mineral density, how it’s measured, how it changes over the course of life, and the variability between sexes largely due to changes in estrogen levels. From there he provides insights into ways that one can improve bone health, from exercise to nutrition supplements to drugs. Additionally, Peter discusses what happens when one may be forced to be sedentary (e.g., bedrest) and how you can...

Rachel Rubin is a board-certified urologist and one of the nation's foremost experts in sexual health. In this episode, she shares her deep expertise on the often-overlooked topic of women’s sexual health, exploring why this area remains so neglected in traditional medicine and highlighting the critical differences in how men and women experience hormonal decline with age. Rachel explains the physiology of the menstrual cycle, the complex hormonal shifts of perimenopause, and the wide-reaching health risks associated with menopause, including osteoporosis, cardiovascular disease, dementia, and recurrent urinary tract infections. She also breaks down the controversy surrounding hormone replacement therapy (HRT), particularly the damaging legacy of the Women’s Health Initiative study, and provides guidance on the safe and personalized use of estrogen, progesterone, and testosterone in women. With particular emphasis on local vaginal hormone therapy—a safe, effective, and underused treatment—Rachel offers insights that have the potential to transform quality of life for countless women.
