In this episode, David and Matt ask the questions we all want to ask. Could peptides such as humanin help protect the brain against Alzheimer’s disease? Can they accelerate healing, repair damaged tissues, ease arthritis, or improve muscle and gut health? Might they eventually offer new ways to treat age-related diseases? They also separate promising science from hype, examining which peptides have credible evidence from human studies, which remain experimental, and what we know about their safety. The conversation also looks at the first FDA-approved…

Could they also extend lifespan? In this episode, David and Matt look at the emerging science behind that question. They examine a recent study in which semaglutide extended lifespan in female mice, evidence that GLP-1s may influence multiple hallmarks of aging, plus early human research examining biological aging. They also explore how these drugs work, the potential role of the brain, the promise and unanswered questions around microdosing, and what the next generation of GLP-1 therapies could mean for longevity medicine.

Dr. Sinclair explains how diet affects key biological processes tied to metabolism, health, and longevity. Dr. Sinclair breaks down what sugar does inside the body, including glycation - the process by which sugar attaches to proteins and disrupts their function. The conversation also explores why inflammation rises with age, how the gut microbiome changes over time, and why our ability to sense and respond to nutrients can decline as we get older.

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.
