Meal timing becomes increasingly important for women in perimenopause and menopause as hormonal shifts change how the body handles energy, hunger, and fat storage. Research shows that morning cortisol patterns, declining insulin sensitivity later in the day, and changes in metabolic flexibility all influence weight gain and energy levels during midlife. Simple adjustments — like delaying early calories, eating dinner earlier, and allowing a gentle overnight fast — can support better blood‑sugar control, reduce abdominal fat, and improve overall energy.
