Our Verdict
Winner: Semaglutide
Semaglutide achieves nearly double the weight loss of liraglutide (14.9% vs 5-8% body weight) with once-weekly vs daily injections. Direct comparative trials consistently favor semaglutide. Unless liraglutide is specifically required for clinical reasons, semaglutide is the superior choice for weight management.
