Many midlife women suddenly gain 8–15 pounds within a few years — even when eating the same way. This isn’t “discipline loss.” It’s biology. Research from the Mayo Clinic shows that resting metabolic rate decreases 5–10% during perimenopause, meaning your body burns fewer calories at rest. Meanwhile: Insulin sensitivity drops, causing stronger sugar cravings Cortisol rises, increasing abdominal fat storage Sleep fragmentation triggers appetite hormones And muscle mass declines by up to 1% per year after 40 This combination can feel like betrayal. What helps: Protein at 25–30g per meal stabilizes glucose and preserves muscle Strength training 2–3× weekly increases metabolic rate Fiber (25–30g/day) regulates insulin and supports gut health Nighttime screen limits reduce cortisol spikes Your body isn’t “losing control.” It’s transitioning. Understanding these shifts gives you power — not punishment. #WomensHealth #Metabolism #MidlifeWellness Keywords: midlife metabolism slowdown
