Estrogen (E2) reduces adiposity and adipocyte size independently of energy intake by down-regulating lipogenic genes (SREBP-1c, FAS, ACC-1) and up-regulating lipid oxidation pathways (PPAR-alpha, AMPK) in skeletal muscle and adipose tissue.

If you are post-menopausal or have low estrogen, you may experience increased abdominal fat storage due to metabolic changes, not just eating more. Estrogen replacement therapy can help maintain leanness by shifting your body to burn fat rather than store it, acting directly on your muscles and fat cells.

These data demonstrate that chronic estrogen treatment promotes smaller adipocytes and reduced adipose mass independently of reduced energy intake in OVX mice.
