New generation obesity medications (GLP-1/GIP agonists) achieve mean weight loss of 15–25% over 68–72 weeks, narrowing the efficacy gap between medical and surgical management of obesity.

New GLP-1/GIP medications like semaglutide (2.4mg weekly) and tirzepatide are highly effective, producing 15-25% weight loss over ~1.5 years. This efficacy is now comparable to surgery, making medication a primary, not just secondary, option for obesity treatment.
