#372 - AMA #77: Dietary fiber and health outcomes: real benefits, overhyped claims, and practical applications
The Peter Attia Drive
In this “Ask Me Anything” (AMA) episode, Peter breaks down the science of dietary fiber, moving beyond the blanket advice to “eat more fiber” to uncover what it actually does in the body and where its benefits are truly supported by evidence. He explains how different types of fiber—soluble, insoluble, viscous, and fermentable—affect digestion, satiety, weight management, and glycemic control, and compares their impact to other, more potent metabolic tools. Peter also examines how certain fibers influence lipid metabolism and cardiovascular risk, evaluates the strength of...

#370 - AMA #76: Peter evaluates longevity drugs, aspirin for CVD, and strategies to improve muscle mass — proven, promising, fuzzy, noise, or nonsense?
The Peter Attia Drive
In this “Ask Me Anything” (AMA) episode, Peter revisits the “proven, promising, fuzzy, noise, nonsense” scale and applies it to a variety of popular topics. He begins with a refresher on what each category represents before classifying a range of interventions based on the strength of their supporting evidence. The conversation spans three main areas: drugs for geroprotection (including GLP-1 receptor agonists, SGLT2 inhibitors, methylene blue, and telomere-lengthening supplements), the use of low-dose aspirin for cardiovascular disease prevention, and strategies to improve muscle...

#369 ‒ Rethinking protein needs for performance, muscle preservation, and longevity, and the mental and physical benefits of creatine supplementation and sauna use | Rhonda Patrick, Ph.D.
The Peter Attia Drive
Rhonda Patrick is a scientist, health educator, and host of the FoundMyFitness podcast whose work explores the intersection of nutrition, aging, and disease prevention. In this episode, Rhonda joins Peter for part two of his deep dive on protein, continuing last week’s discussion with David Allison and expanding the conversation to include creatine supplementation and sauna use. She discusses why the current RDA for protein is insufficient, how much more is needed to maintain muscle mass and prevent frailty, how activity level and aging influence protein requirements through mechanisms...

#368 ‒ The protein debate: optimal intake, limitations of the RDA, whether high-protein intake is harmful, and how to think about processed foods | David Allison, Ph.D.
The Peter Attia Drive
David Allison is a world-renowned scientist and award-winning scientific writer who has spent more than two decades at the forefront of obesity research. In this episode, David joins for his third appearance on The Drive to bring clarity to one of the most contentious topics in modern nutrition—protein. He explores the historical pattern of demonizing macronutrients, the origins and limitations of the RDA for protein, and what the evidence really says about higher protein intake, muscle protein synthesis, and whether concerns about harm are supported by actual data. He also discusses the...

#367 - Tylenol, pregnancy, and autism: What recent studies show and how to interpret the data
The Peter Attia Drive
In this special episode of The Drive, Peter addresses the recent headlines linking acetaminophen (Tylenol) use during pregnancy to autism in exposed children. Recognizing the confusion these claims have sparked among patients, listeners, and the broader public, Peter uses this episode to provide a framework for thinking critically about complex conditions and the research related to them. He highlights the dramatic rise in autism diagnoses over recent decades, noting that multifactorial conditions rarely have a single cause, and emphasizes the importance of resisting oversimplified...

Keith Flaherty is the director of clinical research at the Massachusetts General Hospital Cancer Center and a previous guest on The Drive. In this episode, Keith first delves into the statistics on cancer's prevalence as we age, underscoring the significance of finding effective treatments and early detection methodologies. He touches on the history of cancer therapeutics and illuminates the notable enhancements in cancer therapy within the last decade that are setting the stage for a promising future. He goes into detail on the potential of immunotherapy and therapies that can combat cancer’s evasive tactics while explaining some of the existing challenges around specificity, cost, and scalability. Additionally, Keith highlights the significant leap in early detection methodologies, namely liquid biopsies, which have the potential not only to determine if a cancer is present in an early stage, but also identify the possible tissue of origin.
