Semaglutide (2.4 mg once-weekly) produces significant, sustained weight loss (10-15%) and improves cardiometabolic markers in non-diabetic individuals with obesity or overweight, primarily by mimicking GLP-1 to reduce appetite and energy intake.

If you have obesity or are overweight without diabetes, semaglutide (2.4 mg weekly) is a highly effective medical treatment that can help you lose 10-15% of your body weight and improve your metabolic health. It works by reducing your appetite. While it can cause temporary stomach issues like nausea, these often subside. It works best when combined with diet and exercise, but it is significantly more effective than lifestyle changes alone for substantial weight loss.

By activating GLP-1 receptors in the brain, semaglutide helps to decrease appetite, increase feelings of fullness, and reduce food intake, ultimately leading to weight loss... participants receiving semaglutide demonstrated significant weight loss compared to those on placebo or other anti-obesity medications. The magnitude of weight loss varied across studies, 13 of 16 with some reporting an average reduction of 10%-15% of body weight over a treatment period of 68 weeks.
