Researchers at the University of Copenhagen have identified a signaling pathway that simultaneously increased energy expenditure and decreased food intake. In both human and primate studies, agonists of the tachykinin NK2 receptor (NK2R) led to both decreased food intake and increased energy expenditure. And in behavioral tests, they were not aversive, suggesting they do not cause the nausea that is a major side effect of GLP-1 agonists.
