#375 - Ketogenic diet, ketosis & hyperbaric oxygen: metabolic therapies for weight loss, cognition, Alzheimer’s & more | Dom D’Agostino, Ph.D.
The Peter Attia Drive
Dom D'Agostino is a neuroscientist and professor at the forefront of metabolic therapies, including ketogenic diets, exogenous ketones, and hyperbaric oxygen. In this episode, Dom breaks down nutritional versus supplemental ketosis, defines meaningful ketone thresholds, and outlines practical ways to achieve ketosis. He explains how a ketogenic diet can support metabolic health and weight loss, and advises on how to maintain adequate protein and avoid common mistakes. Dom surveys the growing landscape of exogenous ketones—from salts and esters to 1,3-butanediol—and effective pairings...

#374 - The evolutionary biology of testosterone: how it shapes male development and sex-based behavioral differences, | Carole Hooven, Ph.D.
The Peter Attia Drive
Carole Hooven is a human evolutionary biologist whose research centers on testosterone, sex differences, and behavior. In this episode, she explores how prenatal testosterone orchestrates male development in the body and brain, how early hormonal surges shape lifelong behavioral tendencies, and what rare natural experiments—such as 5-alpha-reductase deficiency—reveal about the biology of sex differentiation. She discusses distinct male and female aggression styles through an evolutionary lens, how modern environments interact with ancient competitive drives, and the implications of...

Wendy Chung is a board-certified clinical and molecular geneticist with more than 25 years of experience in human genetic disease research. In this episode, Wendy delves deep into the world of genetics by first exploring the historical landscape of genetics prior to decoding the human genome, contrasting it with what we know today thanks to whole genome and exome sequencing. She provides an overview of genetic testing by differentiating between various genetic tests such as direct-to-consumer, clinical, whole genome sequencing, and more. Additionally, Wendy unravels the genetic underpinnings of conditions such as PKU, breast cancer, obesity, autism, and cardiovascular disease. Finally, Wendy goes in depth on the current state and exciting potential of gene therapy while also contemplating the economic implications and ethical nature of gene editing.
