Intermittent fasting

Time-restricted eating and alternate-day fasting do produce weight loss in randomised trials. When those trials match the calories, fasting schedules generally do not beat ordinary calorie restriction, which suggests the timing is a tool for adherence rather than a distinct metabolic effect. Longer-term outcome data is still sparse.
