In this episode, Matt and Brian Kennedy delve into various topics, including caloric restriction, lifespan studies, rapamycin, and the critical role of control groups in research. They examine the validity of certain claims related to longevity, explore the complexities of ageing mechanisms, and question the efficacy of supplements.

Key Points:

This episode dives deep into the science of ageing, exploring interventions like dietary energy reduction, rapamycin, and NAD+ supplementation, alongside broader lifestyle factors. The discussion emphasizes the complexity of biological ageing and the challenges of translating scientific findings into actionable health strategies.

• Caloric Restriction as a Benchmark: Caloric restriction remains a gold standard in ageing research, with studies showing significant lifespan extensions, though ethical constraints limit replication in modern labs.
• Rapamycin and Longevity: Rapamycin shows promising effects on lifespan in mice, with timing and dosing playing critical roles. Its interactions with caloric restriction and other interventions are still under investigation.
• NAD+ and Cellular Ageing: Supplementation with NAD+ precursors like NR and NMN is debated. Novel delivery methods, such as sublingual formulations, show promise in enhancing endurance and metabolic health.
• Interplay of Diet, Exercise, and Longevity: The podcast stresses personalized approaches to diet and exercise, discouraging extreme fads while endorsing moderation and balance as key principles.
• Challenges in Scientific Interpretation: The hosts highlight the importance of critical thinking when evaluating ageing research, cautioning against oversimplified claims and unverified supplements.
• Future of Personalized Medicine: Advances in biomarkers could enable tailored interventions for maximizing health span, though practical applications are still developing.
