An enlightening conversation with a FMD expert (from Prolon) on my usage of FMD (with exercise and lifestyle) to help a fit older athlete manage body comp (more muscle and less fat) while not interfering with muscle building or cardiovascular fitness efforts (endurance and HIIT). It’s an useful deep dive into calorie deficits (lose fat) and surpluses (gain muscle), high protein for recovery and muscle / mito building vs low protein during calorie deficits to triggering autophagy, and more.
