Once-weekly subcutaneous semaglutide 2.4 mg produces significant, sustained weight loss (mean 11.80% body weight reduction) and improves cardiometabolic markers in non-diabetic overweight or obese adults compared to placebo.

For non-diabetic adults with obesity, once-weekly 2.4 mg subcutaneous semaglutide is a highly effective intervention for significant weight loss (approx. 12% body weight) and metabolic improvement. While gastrointestinal side effects are common, they are generally manageable and transient.

The findings indicated that, in comparison to the placebo group, semaglutide caused a significant and sustainable reduction in the percentage of body weight (BW; mean difference [MD]: (cid:1)11.80% [95% confidence interval {CI} (cid:1)12.93, (cid:1)10.68]; P < 0.00001)... Moreover, it achieved a higher proportion of patients who experienced weight loss exceeding 5%, 10%, 15% and 20%. Furthermore, semaglutide showed significant efficacy in controlling blood pressure, blood sugar levels, C-reactive protein levels, and lipid profiles.
