The Peter Attia Drive

A deep dive into colorectal cancer screening, focusing on why early detection can prevent disease. Discussion of how polyps progress and the long window for intervention. Examination of colonoscopy as both a diagnostic and preventive tool, plus how to assess preparation and procedure quality. Overview of rising early-onset cases and the pros and cons of noninvasive screening alternatives.

A fast-moving Q&A dives into family health history, why heart disease still slips through the cracks, and whether extra body fat can coexist with good metabolic markers. It also touches on time-efficient strength training, ways to lower dementia risk, the case for NAD supplements, and when hydration hacks actually matter.

A deep dive into why scientific thinking feels so unnatural, and how certainty, identity, and social instincts can quietly distort belief. It explores misinformation, the gap between proof and evidence, how to judge reasoning instead of bold claims, and how to choose trustworthy experts without falling for fake contrarianism.

A deep dive into why prostate cancer screening guidelines may be missing dangerous disease. The conversation explores PSA trends, MRI, PSA density, and safer biopsy methods reshaping early detection. It also looks at active surveillance, flawed anti-screening evidence, and how drugs like finasteride can hide warning signs.

A deep dive into the fast-growing world of peptides, where biology, medicine, and marketing collide. The conversation explores gray-market compounds versus approved therapies, how to judge bold claims, what human and animal evidence can really show, and why sourcing, labeling, and testing matter so much.

A deep dive into aging clocks, DNA methylation, and the difference between chronological age, biological age, and aging speed. It explores why these tools fascinate researchers, how newer clocks try to predict lifespan and decline, and why noisy data can muddy the picture. Two major studies add intrigue, including lifestyle interventions, brain MRI, dementia risk, and mortality.

A wide-ranging AMA tackles how health priorities change with age, which chronic diseases are easiest or hardest to prevent, and why dementia risk is so tricky. It also gets into wearables, DEXA scans, diet sodas, protein and mTOR, habit formation, and training for balance, stability, and injury recovery.

A deep look at obicetrapib and why this CETP inhibitor has revived interest in a once-failed drug class. A concise history of prior CETP trials and what made them stumble. Clear breakdowns of how CETP alters HDL, LDL, ApoB, and Lp(a). Emerging Alzheimer’s biomarker signals, especially in APOE4 carriers, and what trials like BROADWAY are showing.

Layne Norton, Ph.D., a nutrition scientist and accomplished power athlete, dives deep into the seed oil debate. He argues that seed oils aren't uniquely harmful, focusing on the evidence surrounding LDL oxidation and atherosclerosis. Norton critiques the common anti-seed oil claims while highlighting biases in scientific studies. He also discusses the influence of industrial processing and ancestral diets, offering practical dietary guidance for healthier choices—emphasizing that broader lifestyle factors are more pivotal to health than just dietary fats.

Explore the importance of cardiorespiratory fitness as a key predictor of longevity. Discover what zone 2 training really means and how to effectively measure your VO₂ max. Learn tailored strategies for different fitness levels, from beginners to older adults, and why women may need special considerations. Peter also clarifies the balance between zone 2 and high-intensity workouts, and discusses the impact of age on VO₂ max. Get insights on avoiding common cardio-training mistakes and optimizing your healthspan!
