Exercise, Heat, Cold & Other Stressors for Longevity | Episode 3
In Episode 3 of the Lifespan Podcast, Dr. David Sinclair and Matthew LaPlante dive deeply into the science of non-dietary interventions that mimic adversity and promote health. They begin by highlighting how different types of physical activity (i.e., low-intensity aerobic exercise, high-intensity aerobic exercise, and weight training) protect against age-related disease and enhance longevity. David and Matthew additionally highlight the latest evidence behind hyperbaric oxygen therapy, cold therapy, and heat therapy. As they discuss different adversity mimetics, they also explain how these interventions influence aging at the molecular and physiological levels.

What to Eat & When to Eat for Longevity | Episode 2
In this episode, Dr. David Sinclair and co-host Matthew LaPlante discuss how frequently we should eat, what food we should avoid, and what food we should pursue. They discuss the science behind how a "low energy state," which can be induced by a period of fasting, combats aging and promotes health. They also walk through research that points to the benefits of a mostly plant-based diet for slowing aging and offer key insights into when to eat and what to eat to maximize longevity.

The Science Behind Why We Age | Episode 1
In this episode, Dr. David Sinclair and co-host Matthew LaPlante discuss why we age. In doing so, they discuss organisms that have extreme longevity, the genes that control aging (mTOR, AMPK, Sirtuins), the role of sirtuin proteins as epigenetic regulators of aging, the process of "ex-differentiation" in which cells begin to lose their identity, and how all of this makes up the "Information Theory of Aging", and the difference between "biological age" and "chronological age" and how we can measure biological age through DNA methylation clocks.

Season 1 will be 8 episodes in total and will launch on Wednesday, January 5, 2022. New episodes will be released every Wednesday morning of both January and February 2022. This podcast can also be found on YouTube: My goal in creating this podcast is to discuss the science behind why we age and to share the newest research on what we can do to slow, stop and even reverse aging. In doing so, I hope to help explain the science in an easy-to-understand manner and I hope to help all our listeners in their journey to be healthier at any stage of life. Upcoming episodes will cover: why aging is a disease, the impact of dietary choices, fasting and exercise on aging, how various supplements and prescription drugs can protect against aging, why cosmetic aging occurs and how to combat it, the benefits and advancements of biotracking, and the future of age reversal. Please subscribe, share with friends, leave a comment or review, and most of all, thank you for coming with us on this journey into the mechanisms of aging and exploration of the tools for living longer, healthier lives!
