#222 ‒ How nutrition impacts longevity | Matt Kaeberlein, Ph.D
Dr. Matt Kaeberlein is a globally recognized expert on the biology of aging and recurring on The Drive. In this episode, Matt explains his research findings on nutrition as it relates to aging and longevity, including the results from his recent review article in Science. From there, he and Peter dive deep into the literature on calorie restriction (CR), explaining the nuance, benefits for lifespan and healthspan, and potential downsides of CR. He discusses the epigenetic changes that occur with age and potential benefits and downsides of epigenetic reprogramming, often viewed as a panacea for reversing aging. Matt also explains the impact of dietary protein on aging, including the interesting dichotomy around how protein, a critical macronutrient, and rapamycin, a geroprotective molecule, have opposite effects on mTOR. Additionally, he talks about low-protein vs. high-protein diets and their effects on muscle mass and mortality, as well as the impact of IGF-1 signaling and growth hormone on lifespan.
We discuss:

Celia Morgan is a Professor of Psychopharmacology at the University of Exeter who has authored numerous publications on the potential therapeutic uses of ketamine in mental healthcare. In this episode, Celia dives deep into the neurobiology of ketamine, how it affects users, and how it differs from other, more classical psychedelics (LSD, MDMA, PCP, and psilocybin). She explains the potential promise of ketamine as a treatment for recalcitrant depression and addiction, and she details the results from her clinical trials in these areas. She discusses the importance of using ketamine in combination with psychotherapy to maximize its benefits, the potential risks associated with ketamine use, and advice for those interested in the therapeutic use of ketamine.

#219 ‒ Dialectical behavior therapy (DBT): skills for overcoming depression , emotional dysregulation, and more | Shireen Rizvi, Ph.D., ABPP
Shireen Rizvi is a Professor of Clinical Psychology and Psychiatry at Rutgers University, where she is also the Director of the Dialectical Behavior Therapy Clinic. This episode focuses specifically on dialectical behavior therapy (DBT), a skills-based technique which was originally developed to treat borderline personality disorder (BPD) and has since been adapted to treat depression and other mental health conditions, as well as to help people who have difficulty with emotional regulation and self-destructive behaviors. Shireen explains the origins of DBT and how its creator, Dr. Marsha Linehan, came to find a need for something beyond cognitive behavioral therapy (CBT) when attempting to treat patients with suicidal behavior. From there, Shireen dives into how DBT works to resolve the apparent contradiction between self-acceptance and change to bring about positive changes in emotional regulation, interpersonal effectiveness, mindfulness, distress tolerance, and more. She also provides examples for how one can apply specific skills taught with DBT such as accessing the “wise mind,” applying radical acceptance, using the “DEAR MAN” technique, and utilizing an emotion regulation skill called “opposite action.” Finally, she explains how the tenets of DBT offer benefits to anyone, and she provides insights and resources for people wanting to further explore DBT.
We discuss:
The basics of dialectical behavior therapy (DBT) and how it differs from cognitive behavioral therapy (CBT) [3:00];
In this “Ask Me Anything” (AMA) episode, Peter dives deep into the question of whether there is such a thing as “too much exercise.” He explores the theoretical “J-curve” relationship between exercise and longevity, whereby mortality risk declines with increasing activity levels only to see an uptick above a certain exercise volume threshold. While Peter maintains that exercise is perhaps the single most important tool we have to live longer and live better, he explains the challenges involved in identifying an optimal dose. He takes a hard look at studies—many of which have contradictory results—to highlight major limitations in methodology and how readers could be misled. Additionally, he discusses the rare, but real, risks associated with extreme levels of physical activity and concludes by weighing the benefits against the risks of exercise.
