What is the impact of the luteal phase on energy intake for women?
Research indicates that during the luteal phase, women may consume an additional 92–500 kcal per day (caution: such aggressive deficits trigger adaptive thermogenesis — a moderate 300-500 kcal deficit is safer and more sustainable) compared to the follicular phase, with a notable increase in carbohydrate intake. This heightened energy consumption, combined with water retention, contributes to the typical premenstrual weight gain.
