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.

Discover why the standard B12 test might be missing your deficiency, and learn the better biomarkers that could reveal if brain fog, fatigue, and cognitive decline are actually nutrition-related rather than age-related.

In this deep dive with Dr. Martin Warren, Chief Scientific Officer at the Quadrum Institute and leading B12 researcher, we explore why vitamin B12 deficiency is far more common and complex than most people realize. Dr. Warren explains why standard B12 blood tests are unreliable (with only 50/50 accuracy for detecting deficiency), why the current deficiency cutoff of 148 picomolar may be too low, and how homocysteine and methylmalonic acid are better indicators of functional B12 status. He reveals that B12 deficiency can masquerade as normal aging—causing brain fog, fatigue, and cognitive decline—but is often reversible with proper treatment. The discussion covers why plant-based diets create deficiency risks, how absorption changes with age due to intrinsic factor decline, the connection between B12 and brain health (including white matter damage), and practical testing and supplementation strategies. Dr. Warren also makes a compelling case for revolutionizing healthcare through regular micronutrient monitoring rather than waiting for disease symptoms to appear.

Dr. Nathan Bryan, the world's leading nitric oxide researcher, reveals how this simple molecule could be the key to preventing and reversing Alzheimer's disease, heart disease, and diabetes. He explains why nitric oxide drops by 80% after age 60 and shares practical solutions including his revolutionary lozenge technology.

In this comprehensive interview, Dr. Nathan Bryan, founder of Bryan Therapeutics and author of "The Secret of Nitric Oxide," breaks down decades of groundbreaking research on nitric oxide's role in human health. Dr. Bryan explains how nitric oxide functions as both a vasodilator and hormone, controlling blood flow, immune function, stem cell mobilization, and cellular energy production.

Key topics covered include:

Why nitric oxide production declines dramatically with age (down to 20% by age 60)

The two pathways your body uses to produce nitric oxide and what disrupts them

How mouthwash, antacids, and poor diet destroy nitric oxide production

The connection between nitric oxide deficiency and Alzheimer's, heart disease, and diabetes

Dr. Bryan's innovative lozenge technology that produces nitric oxide directly in the mouth

Practical lifestyle strategies: intermittent fasting, avoiding sugar, tongue scraping, and dietary choices

Future drug therapies in development for Alzheimer's, heart disease, and wound healing

Dr. Bryan presents compelling evidence that nitric oxide deficiency is the root cause of most age-related diseases and offers hope for prevention and reversal through targeted supplementation and lifestyle modifications.
