#409 ‒ Inside modern drug development: the science, economics, and regulatory hurdles behind bringing new medicines to patients | Lloyd Klickstein, M.D., Ph.D.
The Peter Attia Drive
Lloyd B. Klickstein is a physician-scientist who has spent more than 20 years at the intersection of drug discovery, healthy aging, and preventive medicine. Drawing on his experience in academic medicine, translational research, and biotechnology, Lloyd walks through the full arc of modern drug development. He explains how scientists identify an unmet medical need and decide which diseases and therapeutic targets are worth pursuing. From there, he takes us through the process of engineering a drug, testing it in animals, and navigating clinical trials and regulatory approval. Using...

#408 ‒ AMA #89: Thyroid health: interpreting symptoms, diagnosing and treating dysfunction, and navigating the gray zone
The Peter Attia Drive
In this "Ask Me Anything" (AMA) episode, Peter takes a deep dive into thyroid health and explains why diagnosing and managing thyroid dysfunction is unusually complex. He begins with the basic biology of the thyroid gland and three commonly measured hormones—free T4, free T3, and TSH. He explains how T4 is converted to the active hormone T3 and the important functions T3 performs throughout the body. He also explains what reverse T3 is and when it may be useful to measure it. Peter then breaks down thyroid blood tests and their limitations and provides a practical framework for evaluating...

#407 ‒ Preventing cardiovascular and Alzheimer’s disease: lowering LDL early, APOE4, and promising new therapies | Michael Davidson, M.D.
The Peter Attia Drive
Michael Davidson is a world-renowned cardiologist, lipidologist, and the founding CEO of NewAmsterdam Pharma. He begins this episode by sharing how his family history shaped his interest in lipidology and primary prevention. He explains why prevention should focus on causal drivers of disease rather than near-term risk and examines the causal relationship between LDL and atherosclerotic cardiovascular disease. Michael then traces the complicated history of CETP inhibitors—from the original rationale that raising HDL would reduce cardiovascular risk to the failures of torcetrapib,...

Blood pressure: how to measure, manage, and treat high blood pressure (AMA #48 rebroadcast)
The Peter Attia Drive
In this “Ask Me Anything” (AMA) episode, Peter delves into the critical subject of blood pressure, which is one of the three primary causes of atherosclerosis, along with high apoB and smoking. He begins by unraveling the nature of high blood pressure, its prevalence, and why it often goes undiagnosed. Peter describes in detail the proper way to accurately measure blood pressure and what determines a diagnosis. Next, Peter discusses the actionable steps one can take in response to high blood pressure, shedding light on the extent to which factors like weight loss, exercise, and...

#406 ‒ Migraine, cluster headache, and tension headache: symptoms, causes, prevention, and treatment | Brian Grosberg, M.D.
The Peter Attia Drive
Brian Grosberg is a world-renowned headache specialist who joins Peter to provide a master class on the diagnosis and treatment of headache disorders. In this episode, Brian explains the distinction between primary and secondary headaches and breaks down the defining features of the "big three" primary headache types (migraine, cluster, and tension headache)—highlighting how often they are misdiagnosed and how they are treated. He explores the epidemiology of headaches, describing migraine as an invisible disease affecting about 12% of the population, disproportionately affecting women,...

#405 ‒ AMA #88: Metabolic liver health: how to assess risk, catch dysfunction early, and prevent or reverse liver disease
The Peter Attia Drive
In this "Ask Me Anything" (AMA) episode, Peter takes a deep dive into the liver and its central role in metabolic health. He explains why the liver can serve as a "canary in the coal mine" for metabolic dysfunction and explores how insulin resistance, visceral fat, alcohol consumption, genetics, and hormones contribute to liver disease, along with how increasing muscle mass can benefit liver health. Peter provides a framework for understanding the progression of liver disease, highlighting which stages are reversible and why early detection matters. He explains why normal liver enzymes can...

#404 ‒ Mental health beyond neurotransmitters: the role of hormones in psychiatry, why symptom reduction isn't enough, and the future of psychedelic therapies | Linus Abrams, M.D.
The Peter Attia Drive
In this episode, Peter sits down with Dr. Linus Abrams, a psychiatrist with nearly 35 years of clinical experience specializing in mood disorders and psychopharmacology, to explore how our understanding of mental health is evolving beyond the traditional neurotransmitter model. After decades in practice, Linus began questioning many of the assumptions underlying modern psychiatry, leading him to investigate how hormones, metabolism, inflammation, circadian biology, and the endocrine system shape mood and cognition. Together, Peter and Linus examine why psychiatric care should aim not only...

John Kastelein is a renowned expert in lipoprotein metabolism and atherosclerotic cardiovascular disease (ASCVD) research. In this discussion, John delves deep into familial hypercholesterolemia (FH), a genetic disorder characterized by high levels of LDL cholesterol in the blood that increases the risk of developing heart disease. He covers its definition, genetic underpinnings, and clinical identification. He then explores the therapeutic options available for the prevention and treatment of cardiovascular disease, including the captivating history of CETP inhibitors. He explains the past shortcomings of previous CETP inhibitors before underscoring the compelling potential of the latest iterations, not only for cardiovascular disease but also for conditions like Alzheimer's disease and type 2 diabetes. Moreover, he unveils the intricate role of APOE, shedding light on why the APOE4 isoform codes for a protein that significantly increases the risk of Alzheimer's disease and cardiovascular disease. Concluding the discussion, John shares a profound sense of optimism, envisioning the possibility of targeted therapeutic interventions for high-risk patients in the near future.
