Popular obesity and diabetes drugs called GLP-1 medications may have added benefits, with a new study finding they helped heavy drinkers cut alcohol consumption by nearly 70%. The study, published Friday during the 32nd European Congress on Obesity in Spain, also found these GLP-1 drugs were more effective than a drug called nalmefene, which is approved in Europe explicitly to help people cut back on alcohol. For the study, researchers followed 262 adults who were prescribed GLP-1 medications like semaglutide or liraglutide to help with weight loss.
