Dr. Dom D’Agostino — Ketone and metabolic researcher. In The Keto Project (2025), the documentary about a fit doctor who ate 600 burgers in 30 days.
We filmed Dr. Dom D’Agostino in his lab for The Keto Project. The film introduces him with the title “World’s Leading Keto Expert.” The question we brought him: what are ketones actually doing in the body?

In the film Dom walks through it step by step. Ketones rise in the blood on a ketogenic diet, with ketone supplements, or with fasting. In his words they “become alternative energy substrates for your heart and your brain.” He also takes the question of whether the brain prefers glucose or ketones, and he doesn’t give the easy answer. That exchange is in the film.
