Protecting Muscle Mass During Fasting | Peter Attia, M.D.

Well SupportedMaintaining muscle mass requires less effort than building it, suggesting resistance training can preserve muscle during fasting.

Well SupportedApproximately 33% of weight loss from caloric restriction or fasting is lean body mass.

Partially SupportedPeter Attia focused solely on resistance training without cardio during extended fasting periods to stimulate muscle protein synthesis.

Partially SupportedA protein-sparing fast combined with resistance training mitigates muscle loss.
