The Peter Attia Drive

Dr. Kathryn Gray, a physician-scientist and high-risk obstetrician, explores pregnancy’s remarkable cardiovascular, hormonal, and metabolic transformations. She discusses gestational diabetes, preeclampsia, HELLP syndrome, stillbirth, prenatal genetic screening, and the trade-offs of vaginal versus cesarean birth. They also examine breastfeeding, exercise, postpartum depression, and how pregnancy complications can signal long-term health risks.

Lloyd Klickstein, M.D., Ph.D., is a physician-scientist and biotechnology executive specializing in drug discovery, healthy aging, and preventive medicine. He offers a fascinating tour of how medicines move from unmet need to the clinic, covering patents, investment, animal studies, regulation, and trial design. Using bimagrumab, he explores muscle growth, obesity, semaglutide combinations, mTOR inhibition, and a promising approach to cancer prevention.

A deep dive into the thyroid’s complex biology, from T4 and T3 conversion to the limits of blood tests. The discussion explores why common symptoms can mislead, the fine line between undertreatment and overtreatment, subclinical hypothyroidism, Hashimoto’s disease, medication absorption, pregnancy, hyperthyroidism, iodine, and what to consider when symptoms persist despite normal results.

Michael Davidson, a cardiologist, lipidologist, professor, and biotech CEO, explores why lifelong LDL exposure matters and how CETP inhibitors evolved from failed HDL strategies to promising obicetrapib. They discuss APOE4, brain cholesterol, Alzheimer’s prevention, statins and diabetes, omega-3 brain delivery, AI-powered trials, and klotho’s potential as a future therapy.

A deep dive into blood pressure, from what systolic and diastolic readings really mean to the hidden damage hypertension can cause across the heart, brain, and kidneys. Learn how to measure it accurately at home, understand daily and exercise-related fluctuations, spot secondary causes, and explore the roles of sleep, sodium, exercise, weight loss, and medication.

Brian Grosberg, board-certified headache specialist and neurology professor, offers a master class on migraine, cluster, and tension headaches. He explains how to tell the main headache types apart. He discusses epidemiology, genetic and hormonal influences, practical prevention strategies, modern targeted treatments, neuromodulation devices, and when to seek medical care.

A deep dive into the liver's role as an early warning sign of metabolic dysfunction. Discussion of how insulin resistance, visceral fat, alcohol, genetics, and hormones drive liver disease. Clear stages of liver disease and which are reversible. Practical assessments and tools for detecting fibrosis and advanced disease. Evidence-based interventions from diet and exercise to medications and the limits of detox claims.

Linus Abrams, a psychiatrist with nearly 35 years of experience who now integrates endocrinology into mental health care. He explores hormones, metabolism, sleep, inflammation, and why reducing symptoms is not the same as restoring full functioning. They cover how sex hormones and thyroid influence mood, distinctions between bipolar and unipolar presentations, and the promise and limits of ketamine and psychedelic therapies.

A clear guide to evaluating peptides, explaining what they are and why each must be judged on its own merits. A five-question framework and three-tier evidence system help separate solid science from hype. Case studies like BPC-157 and CJC-1295 illustrate murky claims, dosing gaps, and biomarker vs meaningful benefit distinctions. Gray-market sourcing, placebo effects, and why controlled trials and regulatory data matter are also discussed.

Jim Otvos, a biophysical chemist who pioneered NMR lipoprotein testing and developed the first FDA‑cleared LDL‑P assay, explains how a misread cancer test led to a new way of decoding blood. He discusses why particle number can outshine cholesterol, how NMR spots early insulin resistance and chronic inflammation, and the metabolic vulnerability index for predicting frailty and mortality.
