Estrogen (E) and GLP-1 interact to reduce body weight, food intake and food reward.
This interaction can be localized to supramamillary nucleus (SUM), lateral hypothalamus (LH), and nucleus of the solitary tract (NTS).
SUM underlies anorexic, weight loss, and reward effects of GLP-1 and E conjugate.
LH underlies only the anorexic and body weight effects the GLP-1 and E conjugate.
SUM is a novel brain area capable of exerting effects on energy balance and reward.
