One Meal a Day Fasting
One meal a day fasting packs calories into a single meal—high discipline, high risk of under-protein and poor training fuel for most athletes.
One meal a day fasting (OMAD) compresses nearly all daily calories into a single sitting—often a one- to two-hour eating window after twenty-two to twenty-three hours fasted. It simplifies decisions but makes hitting protein, micronutrients, and pre-training carbs hard for active people.
GI discomfort and evening-only eating can disrupt sleep.
Common questions
-
Can athletes build muscle on OMAD?
Possible for a few with enormous single meals and perfect timing, but most lifters do better with at least two protein-rich feedings and carbs around hard sessions.
