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 evidence for fiber's role in colorectal cancer prevention, and highlights why some individuals may not tolerate specific fibers well. The discussion concludes with practical guidance on moving past generic fiber targets toward a more strategic and personalized approach that maximizes the true benefits of fiber.

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 challenges of conducting rigorous nutrition studies, including the limits of epidemiology and crossover designs, as well as conflicts of interest in nutrition science and why transparency around data, methods, and logic matter more than funding sources. The episode closes with a discussion on processed and ultra-processed foods, the public health challenges of tackling obesity, and whether future solutions may depend more on drugs like GLP-1 agonists or broader societal changes. This is part one of a two-part deep dive on protein, setting the stage for next week's conversation with Rhonda Patrick.

We discuss:

The cyclical pattern of demonizing different macronutrients in nutrition and why protein has recently become the latest target of controversy [3:15];
The origin and limits of the protein RDA: from survival thresholds to modern optimization [6:30];
Trust vs. trustworthiness: why data, methods, and logic matter more than motives in science [13:30];
The challenges of nutrition science: methodological limits, emotional bias, and the path to honest progress [17:15];
Why the protein RDA is largely inadequate for most people, and the lack of human evidence that high protein intake is harmful [30:30];
Understanding the dose-response curve for muscle protein synthesis as protein intake increases [45:15];
Why nutrition trials are chronically underpowered due to weak economic incentives, and how this skews evidence quality and perceptions of conflict [48:15];
The limitations and biases of nutrition epidemiology, and the potential role of AI-assisted review to improve it [56:15];
The lack of compelling evidence of harm with higher protein intake, and why we should shift away from assuming danger [1:04:15];
Pragmatic targets for protein intake [1:09:30];
Defining processed and ultra-processed foods and whether they are inherently harmful [1:16:15];
The search for a guiding principle of what's healthy to eat: simple heuristics vs. judging foods by their molecular composition [1:25:00];
Why conventional public health interventions for obesity have largely failed [1:38:15];
Two ideas from David for addressing the metabolic health problem in society [1:42:30];
The potential of GLP-1 agonists to play a large role in public health [1:46:30]; and
More.

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 explanations. Peter also stresses that humans are not naturally wired for scientific thinking, making disciplined frameworks like the Bradford Hill criteria essential for evaluating causality in epidemiology. Ultimately, he uses this framework to explore the evidence surrounding acetaminophen use during pregnancy and its potential link to autism.

We discuss:

Laying the groundwork for this discussion, the rise in autism rates, and the value in using frameworks [1:00];
The FDA pregnancy drug categories, where Tylenol falls within that framework, and a structured method for evaluating scientific evidence and causality [6:00];
What exactly are the claims being made about acetaminophen and autism? [13:45];
The increase in autism rates and why so many things are being linked to autism: the multiple comparisons problem [15:00];

Applying the Bradford Hill criteria: testing the case for Tylenol and autism [45:45];
Putting it all together to answer the question: Does acetaminophen use during pregnancy increase the risk of autism? [56:15];
If autism risk is overwhelmingly genetic, what explains the dramatic rise in autism diagnoses? [59:15];
Other risk factors for autism: parental age, maternal health, environment, and where Tylenol fits in [1:09:15];
Medication use during pregnancy: balancing risks, benefits, and FDA categories [1:15:15];
Considerations for taking Tylenol during pregnancy [1:19:30];
Final thoughts: critical thinking, balanced risk assessment, and the importance of context when evaluating medications like Tylenol during pregnancy [1:22:30]; and

In this "Ask Me Anything" (AMA) episode, Peter explores how to determine the right diet for yourself rather than searching for a universal "best" diet. He begins by laying out five non-negotiable criteria that any sustainable eating pattern must meet—energy balance, metabolic health, adequate protein, micronutrient sufficiency, and long-term adherence—before introducing a practical rubric for evaluating different diets. Using this framework, Peter walks through the ketogenic, carnivore, vegan, and Mediterranean diets, highlighting their strengths, ideal candidates for each, and common pitfalls such as micronutrient gaps or adherence challenges. He explains why this guidance is aimed at people who feel overwhelmed by diet choices, not zealots defending a single approach, and provides practical advice on using tools like DEXA scans, lab markers, continuous glucose monitors, and symptom tracking to assess whether a diet is truly working.
