OMAD

OMAD is positioned as an extreme form of intermittent fasting because it creates one feeding event per day. OMAD is an eating pattern where all daily food is consumed in about a one-hour feeding window with no calories outside that window. During hours 6–12 of OMAD, low insulin allows lipolysis and ketone production. OMAD begins with a post-meal loading phase in which glucose and insulin rise and nutrients are directed toward repair and transport. During hours 3–6 of OMAD, insulin declines and the liver uses glycogen to maintain energy. Hunger during OMAD is presented as partly schedule-driven and adaptable over time. The article recommends progressing gradually toward OMAD rather than starting it abruptly. The signal to advance toward a shorter feeding window is comfort and lack of intense hunger rather than a fixed timeline.
