The Peter Attia Drive
In this episode, Peter explores the complex and often misunderstood world of genetic testing, building a practical framework for understanding what these tests can and cannot actually tell us about health and disease. He explains why some genetic findings can be genuinely life-changing while many others offer information that is far more probabilistic than deterministic, and why directly measuring the phenotype is often more valuable than inferring risk from DNA alone. Peter examines where genetics can provide meaningful insight across the major disease categories and where its predictive...

In this episode, Peter takes a deep dive into colorectal cancer (CRC) screening, explaining why it is one of the most preventable cancers and why getting screening right can have life-saving implications. He walks through how colorectal cancer develops and why it is uniquely well-suited to early detection and prevention, with a particular emphasis on the dual role of colonoscopy as both a diagnostic and therapeutic tool. Peter also examines the concerning rise in early-onset CRC among younger adults, highlighting why awareness and timely screening matter more than ever. The episode provides...

In this “Ask Me Anything” (AMA) episode, Peter answers listener questions across a wide range of topics, focusing on how to think through real-world trade-offs and apply scientific evidence in practice. He explores how to build and interpret a meaningful family health history, how individual risk tolerance influences decisions around testing and treatment, and why heart disease remains poorly prevented despite available tools. He also examines whether it’s possible to carry excess body fat while remaining metabolically healthy, outlines the minimum effective dose for strength training...

In this episode, Peter explores one of the most foundational topics underlying nearly everything discussed on the podcast: how to think scientifically. Framed as an introspective deep dive, he examines why scientific thinking is inherently difficult for humans, the cognitive biases and tendencies that make it challenging to separate belief from evidence, and why these challenges are even more consequential in today’s environment saturated with misinformation. He also offers a framework for improving our ability to evaluate claims, question assumptions, and identify a personal panel of...

In this episode, Peter takes a deep dive into prostate cancer screening, explaining why advanced and metastatic diagnoses continue to rise despite the availability of screening tools, and what can be done to reverse this trend. He breaks down what PSA actually measures and why it is far more informative when tracked over time rather than interpreted as a single value, and he explores how tools like MRI, PSA density, PSA velocity, and improved biopsy techniques can both reduce unnecessary procedures and improve the detection of aggressive cancers. Peter also discusses the role of active...

In this “Ask Me Anything” (AMA) episode, Peter explores the topic of gray-market peptides, one of the most requested and most confusing topics he’s covered on The Drive. Peptides sit at the intersection of biological plausibility, clinical promise, and aggressive commercialization, and are often marketed as cutting-edge therapies for everything from muscle repair and longevity to cosmetic enhancement. Rather than promoting or dismissing peptides wholesale, Peter lays out a clear, repeatable framework for evaluating any peptide or drug—covering mechanism, intended effects, safety,...

In this episode, Peter takes a deep dive into the science and application of aging clocks, unpacking what they are, the differences between chronological age, biological age, and the pace of aging, and what epigenetic clocks may actually be measuring. He explores key research in the field, including a randomized controlled trial that tested simple lifestyle interventions against several commonly used aging clocks, as well as a study using brain MRI to assess the pace of aging and its relationship to dementia risk and mortality. Throughout the episode, Peter highlights the promises and...

In this “Ask Me Anything” (AMA) episode, Peter answers listener questions across a wide range of topics, focusing on practical decision-making and real-world application. He explores how health priorities and strategies should evolve across different decades of life, which chronic diseases are most challenging to manage and how to think about risk hierarchies, and which emerging interventions—beyond exercise—show the most promise for dementia prevention. Peter also breaks down the utility of wearables and explains how to use and interpret DEXA scans effectively. He discusses the...

In this special episode, Peter takes a deep dive into obicetrapib, an investigational drug that has captured his attention and renewed interest in an entire class of therapies known as CETP inhibitors. He explains what obicetrapib is and how it works, revisits the history of CETP inhibitors and why earlier versions of these drugs failed—sometimes dramatically—and breaks down the key clinical trials designed to evaluate their impact on cardiovascular risk. Peter examines how obicetrapib influences major lipid biomarkers, including LDL cholesterol and lipoprotein(a) [Lp(a)], and discusses...

Layne Norton is a nutrition scientist and accomplished power athlete,who returns to The Drive for a conversation that departs from the show’s usual format. In this episode, Layne presents the evidence-based case that seed oils are not uniquely harmful under isocaloric conditions, while Peter steelmans the strongest versions of the opposing argument that seed oils are inherently harmful. They examine how scientific bias and evidence are evaluated, revisit the historical randomized controlled trials that shaped the seed oil controversy, and explore the mechanistic biology underlying LDL...
