The search strategy employed combinations of GLP-1-related terms (‘GLP-1’, ‘glucagon-like peptide-1’, ‘GLP-1 receptor agonist’, ‘semaglutide’, ‘liraglutide’, ‘exendin-4’, ‘dulaglutide’) with eating behavior and neurobiological terms (‘binge eating disorder’, ‘BED’, ‘eating disorder’, ‘feeding behavior’, ‘reward system’, ‘dopamine’, ‘mesolimbic’, ‘food intake’). Here, GCG is linked to eating disorder.
