Dr. Dominic "Dom" D'Agostino (@DominicDAgosti2) is one of my most popular guests, and I'm happy to have him rejoin the show for the third time. (You can listen to Dom's first appearance here, and his second appearance here). Dom is an assistant professor in the Department of Molecular Pharmacology and Physiology at the University of South Florida Morsani College of Medicine, and a senior research scientist at the Institute for Human and Machine Cognition (IHMC) -- which is mentioned in the current issue of Outside Magazine (on which there's a clown who looks a lot like me). Much of Dom's work is related to metabolic therapies and nutritional strategies for peak performance and resilience in extreme environments. Dom's research is supported by the Office of Naval Research (ONR), Department of Defense (DoD), and other private organizations and foundations. In this episode, Dom focuses on disease prevention, cancer, and more mastery of the ketogenic diet. Please enjoy this tutorial and masterclass with Dominic D'Agostino.
