| 0:00.0 | Hello, boys and girls, ladies and germs. This is Tim Ferriss. Welcome to another episode, where it is |
| 0:04.8 | yet again my pleasure after more than a decade to deconstruct world-class performers from all |
| 0:09.7 | different disciplines to tease out the news you can use, the tactics and specifics that you can |
| 0:15.1 | apply to your own life. My guest today is a very popular and repeat guest on this show, Dr. Dominic D'Agostino. |
| 0:23.9 | He is a tenured associate professor in the Department of Molecular Pharmacology and Physiology |
| 0:28.5 | at the University of South Florida, Morsani College of Medicine, and a visiting senior research |
| 0:33.1 | scientist at the Institute for Human and Machine Cognition. He's also one hell of an athlete. And if you were to |
| 0:40.3 | ask me to name one person to ask any question related to ketosis, exogenous ketones, in other words, |
| 0:48.2 | supplemental ketones, anything at all related to the ketogenic diet, metabolic psychiatry, |
| 0:53.8 | if I had to choose someone who |
| 0:55.1 | was a decathlet of the highest order across all of those, it would be Dominic or Dom. He teaches |
| 1:01.5 | medical neuroscience, physiology, nutrition, and neuropharmacology, and his research focuses on |
| 1:06.4 | the development and testing of nutritional strategies. We'll talk about that. And metabolic-based |
| 1:11.1 | therapies for neurological disorders, whether it's depression or chronic inflammation, |
| 1:16.7 | cancer and human performance optimization. He has served as a research investigator and crew |
| 1:21.6 | member on NASA's Extreme Environment Mission Operations, and his research has been supported by |
| 1:26.4 | the Office of Naval Research, the Department of Defense, the National Institutes of Health, and his research has been supported by the Office of Naval Research, |
| 1:28.4 | the Department of Defense, the National Institutes of Health and Nonprofit Foundations, among |
| 1:33.2 | others. We get into a lot in this episode. We get very much into the weeds, so I thought |
| 1:38.2 | I would do something that I rarely do and just share a few of my takeaways. And these are just |
| 1:43.7 | a small sampling, but I wanted to mention a few |
| 1:45.8 | things. For instance, I've been taking various types of supplemental ketones, and they come in |
