The nuclear farnesoid X receptor (FXR) is activated by bile acids and influences energy metabolism. Here, the authors report a small molecule inhibitor of FXR, glycine-ß-muricholic acid, which inhibits FXR in the intestine and improves metabolic homeostasis by repressing intestinal ceramide synthesis.
