Detailed definition
Weight gain in midlife is strongly age-related, but the menopause transition specifically alters fat distribution, shifting it from the gynoid (hip-thigh) pattern toward an android (abdominal/visceral) pattern. The Study of Women's Health Across the Nation found roughly 1.5 lb/year average weight gain across the transition with disproportionate visceral fat accumulation, even when total weight changed little. Mechanisms include: estrogen-deprivation-driven changes in lipoprotein lipase activity favoring visceral storage; age-related sarcopenia reducing resting metabolic rate by 2–3% per decade; sleep disruption affecting leptin/ghrelin balance and increasing caloric intake; cortisol dysregulation; and reduced physical activity. HRT does not cause weight gain in placebo-controlled trials and modestly reduces visceral adiposity. The most effective interventions for menopausal weight management are resistance training, adequate protein intake (1.0–1.6 g/kg/day), sleep restoration, and dietary patterns emphasizing whole foods.
Why it matters in menopause
Many women blame HRT for weight gain that would have happened with menopause regardless. The data don't support HRT as a weight-gain driver. They do support HRT as a tool that, alongside protein and resistance training, can preserve lean mass and reduce the visceral-fat shift.
