Intermittent Fasting

An umbrella term for eating patterns that restrict eating to specific windows or days — most commonly 16:8 daily time-restricted eating, or 5:2 (two reduced-calorie days per week) — marketed for weight loss and broader metabolic and longevity benefits beyond simple calorie reduction.
