Deep within the brain's hunger-regulating architecture, University of Michigan researchers have found a potential lever that could make today's celebrated weight-loss drugs dramatically more powerful. By manipulating two proteins — melanocortin 3 and melanocortin 4 — that govern how the brain interprets fullness and energy reserves, scientists produced fivefold greater weight loss in mice when these proteins were paired with GLP-1 drugs like Ozempic, without amplifying the nausea that burdens so many patients. The discovery, published in the Journal of Clinical Investigation, does not yet touc
