Semaglutide (2.4 mg weekly) produces significantly greater weight loss (15.8%) compared to liraglutide (6.4%) in patients without type 2 diabetes.

If you are struggling with weight loss despite diet and exercise, semaglutide (Wegovy) is currently the most effective registered medication, offering about 15.8% average weight loss over 68 weeks when combined with lifestyle changes. It is taken as a once-weekly injection, which is less frequent than daily options like liraglutide.
