Duke Professor reveals how 90-year-olds tripled their muscle strength in just 10 weeks - and why we've been measuring muscle mass wrong for decades. Dr. William Evans explains the revolutionary new test that predicts disability, mortality, and even Alzheimer's risk. Learn the exact protocols for maintaining muscle mass as you age, the truth about protein requirements, and why your doctor isn't testing for sarcopenia. Plus: critical warnings about GLP-1 weight loss drugs and muscle loss in older adults.

Dr. William Evans is a professor of medicine at Duke University whose pioneering research established sarcopenia as a recognized medical condition. In this episode, he reveals groundbreaking findings about muscle mass and aging that challenge decades of scientific assumptions.

Dr. Evans explains why traditional methods like DEXA scans have been measuring the wrong thing, and introduces his revolutionary creatine-based test that accurately measures muscle mass with just a single urine sample. His research on over 4,000 people proves that muscle mass is central to how we age - affecting everything from physical disability to cognitive function and mortality risk.

We discuss practical strategies for maintaining muscle, including resistance training protocols, optimal protein intake for older adults, and the concerning effects of GLP-1 weight loss drugs on muscle preservation. Dr. Evans also shares insights on hormone therapy, the future of muscle-building drugs, and why exercise remains the single most important intervention for healthy aging and Alzheimer's prevention.

Methylene blue was the first synthetic medicine ever created. 140 years later, we're discovering it might be one of the most powerful tools for brain health and longevity. Here's what the research actually shows.

Dr. Francisco Gonzalez-Lima has spent decades researching methylene blue, the first synthetic medicine in history. In this conversation, he explains how this unique compound enhances mitochondrial function, increases cellular energy production, and reduces oxidative stress; all at very low doses.

We discuss the critical importance of dose (low dose benefits, high dose harms), why pharmaceutical-grade purity matters, and how to personalize your dosing using a simple urine test. Dr. Gonzalez-Lima also addresses common misconceptions from failed Alzheimer's trials and explains why those studies used the wrong approach.

Looking ahead, he shares his plans to combine methylene blue with near-infrared light therapy and MCT oil for his upcoming clinical trial on mild cognitive impairment. Whether you're interested in cognitive enhancement, neuroprotection, or healthy aging, this is essential viewing.

Could a simple supplement that bodybuilders use to build muscle actually help fight Alzheimer's disease? Dr. Matthew Taylor from the University of Kansas reveals surprising results from her groundbreaking clinical trial testing high-dose creatine in Alzheimer's patients

In this episode, Dr. Matthew Taylor discusses his pioneering research on creatine supplementation for Alzheimer's disease, addressing a critical gap in brain energy metabolism that worsens with aging and becomes severely impaired in dementia. His 8-week clinical trial gave 20 Alzheimer's patients 20 grams of creatine daily - a bodybuilder's loading dose - and found remarkable improvements in memory, executive function, and even unexpected gains in reading comprehension. Using advanced MRI spectroscopy, his team confirmed that creatine actually reaches the brain, increasing levels by 11%. Beyond cognitive benefits, participants also showed significant improvements in hand grip strength and muscle mass. Dr. Taylor explains how brain energy metabolism creates a vicious cycle in Alzheimer's, explores whether creatine could prevent dementia in healthy aging, and reveals his plans for combining creatine with ketogenic diet approaches. This conversation offers hope for a simple, accessible intervention that could help millions facing cognitive decline.

A potential functional cure for HIV could be just months away from human trials. Dr. Lanna reveals how her company Sentcell is using cellular rejuvenation to eliminate HIV reservoirs—and the surprising anti-aging benefits that come with it.

n this groundbreaking interview, Dr. Lanna, founder and CEO of Sentcell, explains how his team has developed a revolutionary approach to HIV treatment that could eliminate the need for lifelong antiretroviral therapy. Unlike traditional strategies that target the virus directly, Sentcell's method uses a molecule called DOS to rejuvenate CD4 T-cells, triggering them to naturally clear HIV DNA from their own genomes through a process that mimics elite controllers—rare individuals who can suppress HIV without medication. The treatment works by reactivating dormant cellular pathways that outcompete HIV's integration machinery, effectively reversing viral integration and clearing infected cells within days to weeks. Beyond HIV, Dr. Lanna discusses his team's discovery of "rivers of telomeres"—vesicle structures released by rejuvenated T-cells that can systemically rejuvenate other organs and extend lifespan by 12-17 months in animal studies. With Phase 1 human trials planned for 2026 at University College London, this research represents a potential paradigm shift from managing HIV as a chronic condition to achieving a functional cure.

When someone's LDL cholesterol hits 574 mg/dL, doctors typically expect the worst. But what if everything we think we know about cholesterol and heart disease risk is incomplete?

In this episode, I sit down with researchers Nick Norwitz, Adrian Soto-Mota, and Dave Feldman to discuss their groundbreaking study on lean mass hyperresponders - a rare population who develop extremely high LDL cholesterol on ketogenic diets despite being lean, fit, and metabolically healthy. Their recent paper "Plaque Begets Plaque, ApoB Does Not" challenges conventional wisdom by showing that in this unique population, neither LDL cholesterol nor ApoB levels predicted plaque progression over one year of follow-up. Instead, existing plaque was the strongest predictor of future plaque growth. We explore the proposed lipid energy model that may explain why some people's cholesterol skyrockets on keto, discuss the limitations and implications of their findings, and examine what this means for personalized cardiovascular risk assessment. This conversation touches on fundamental questions about causality in medicine, the importance of studying outlier populations, and why a one-size-fits-all approach to cholesterol management may be missing crucial nuances.

Senescent cells were supposed to be the "easy" target in aging research—clear them out and extend healthspan. But new research reveals the field is far more complex than anyone imagined, with major clinical trial setbacks forcing scientists to completely rethink their approach.

Some links are affiliate links so we will earn a commission when they are used to purchase products.

In this conversation with Dr. Paul Robbins from the University of Minnesota, we explore the evolving world of senescent cell research and senolytics—drugs designed to clear "zombie" cells from our bodies. Dr. Robbins reveals how recent research shows senescence is far more complex than expected, with different types arising from different stresses. We discuss why Unity Biotech's trials failed, mixed results from fisetin studies, and surprising positive signals from Mayo Clinic trials in patients with high senescent cell burden. He explains why future treatments will require personalized cocktails of different senolytics, the potential of alternative approaches, and why he remains optimistic despite setbacks. Dr. Robbins also shares insights into next-generation compounds his lab is developing and hints at positive clinical trial results coming soon.
