Hormonal

Loss of circulating estrogen (E2) due to menopause causes rapid metabolic changes, including reduced metabolic rate, increased central adiposity, and insulin resistance, primarily mediated by estrogen receptor alpha (ERα).

If you are postmenopausal, the drop in estrogen is a major factor in gaining belly fat and developing insulin resistance. While hormone replacement therapy (HRT) can significantly lower diabetes risk, it must be weighed against potential cancer risks. Discuss with your doctor if tissue-selective estrogen complexes (TSECs) or early intervention might be appropriate for your metabolic health.

GoodSupportsHIGH confidence
Clinical trials and animal studies have revealed that loss of circulating estrogen induces rapid changes in whole body metabolism, fat distribution, and insulin action. The metabolic effects of estrogen are mediated primarily by its receptor, estrogen receptor-α.
