Supplemental ketones in the context of fasting | Rhonda Patrick
Parent Episode: Fasting Q&A with Dr. Rhonda Patrick and Mike Maser
During ketogenesis, the metabolic pathway in which organisms produce ketones, the body breaks down fatty acids to use as fuel. The primary ketones used by the body for energy are acetoacetate and beta-hydroxybutyrate. Clinical data suggest that taking supplemental ketones during fasting increases blood levels of ketones but decreases levels of free fatty acids, indicating that the body is no longer relying on stored fatty acids. Although exogenous ketones provide a ready source of energy, their use might interfere with weight loss. In this clip, Dr. Rhonda Patrick describes the effects of endogenous ketones on fat metabolism during a fast.
