A cross-sectional study published online in the Journal of Clinical Endocrinology and Metabolism noted that menopausal women undergoing hormone replacement therapy appeared to have less body fat, especially visceral fat, although the effect disappeared on discontinuation of therapy. The mean percentage of body fat in women undergoing therapy was 34.6%, compared to 36.2% for women who had therapy in the past and 35.9% for women who never had hormone therapy. Mean visceral fat mass, measured as the fat deep in the abdomen around the internal organs, was 0.42 kg for women undergoing therapy, and 0.48 kg both for women with past therapy and those who never received it. Mean body-mass index (BMI) was 24.9 for current users of menopausal hormone therapy, compared to 25.6 for past users and 25.8 for never users.
