Mounjaro works slightly differently from GLP-1 medications, like semaglutide (Wegovy), as it activates both GLP-1 and another hormone called GIP, which together help to promote fat loss, block fat gain and regulate blood sugar.
By combining the effects of GIP and GLP-1 together, Mounjaro is more effective at promoting weight loss through decreased appetite, as well as directly impacting the pathways that lead to fat loss.
To simplify this a bit, this medication helps to reduce your appetite (making you feel fuller far more quickly), assists with turning down cravings, helps improve blood glucose levels and stimulates the breakdown of fat.
