Hormonal

Menopause increases total body fat mass and decreases fat-free mass, leading to a shift toward visceral adiposity, without significantly changing total body weight or BMI.

Do not rely on body weight or BMI to track health during menopause. Expect a shift in body composition: you will likely gain fat (especially visceral) and lose muscle. Prioritize resistance training to preserve lean mass and manage visceral fat, as total weight may remain stable while health risks increase.

GoodSupportsHIGH confidence
Strikingly, these studies indicate that in both healthy-weight and mildly obese women, menopause increases body fat by ~5% of body weight and decreases fat-free body mass by a slightly smaller amount. These opposing changes explain why menopause has no marked effect on body weight or BMI in most studies.
