Butyrate potentiates semaglutide weight loss in diet-induced obese mice

The wire

1. 01In diet-induced obese mice, butyrate significantly amplified semaglutide's body-weight reduction and increased c-Fos-positive cells in the hypothalamic paraventricular nucleus beyond semaglutide alone.
2. 02Dietary restriction decreased PVN c-Fos counts and produced plasma metabolomic profiles with limited overlap with drug treatment, suggesting pharmacologic and caloric weight loss act through different routes.
3. 03Findings are in mice only, with no dose-ranging in humans and no data on whether oral butyrate formulations would reproduce the effect clinically.
