The Tim Ferriss Show #117: Dom D'Agostino on Fasting, Ketosis, and The End of Cancer
Target Moderate Ketone Levels
- Aim for mild nutritional ketosis (1–3 mmol/L) for health and longevity benefits.
- Avoid continuously very high ketone levels (>5 mmol/L) because they induce metabolic acidosis and renal compensation.
Use MCTs And Ketone Supplements
- Combine ketogenic diet with exogenous ketones or MCTs to ease transition and boost performance.
- Use ketone supplements to get benefits without strict long-term dietary restriction.
Rats, Ketone Esters, And Oxygen Tolerance
- D'Agostino's lab gave ketone esters to rats before hyperbaric oxygen and saw dramatic resistance to oxygen toxicity seizures.
- He recalled being astonished when multiple rats far outperformed controls.
Dr. Dominic “Dom" D’Agostino (@DominicDAgosti2) 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). He has also deadlifted 500 pounds for 10 reps after a seven-day fast. He’s a beast and — no big surprise — he’s a good buddy of Dr. Peter Attia, my MD friend who drinks "jet fuel" in search of optimal athletic performance. The primary focus of Dom's laboratory is developing and testing metabolic therapies, including ketogenic diets, ketone esters and ketone supplements to induce nutritional/therapeutic ketosis. D’Agostino’s laboratory uses in vivo and in vitro techniques to understand the physiological, cellular and molecular mechanism of metabolic therapies and nutritional strategies for peak performance and resilience. His research is supported by the Office of Naval Research (ONR), Department of Defense (DoD), private organizations and foundations.
