Semaglutide (GLP-1 receptor agonist) significantly reduces body weight, BMI, and waist circumference in overweight or obese adults, with or without type 2 diabetes, compared to placebo or other glucose-lowering medications.

If you are overweight or obese (BMI ≥24), semaglutide is a highly effective medical intervention for weight loss, working for both diabetic and non-diabetic individuals. It significantly reduces body weight, BMI, and waist circumference compared to placebo. While it can cause gastrointestinal side effects like nausea, serious adverse events are not more common than with a placebo. Be aware that stopping the medication may lead to weight regain, so long-term management and lifestyle changes are crucial.

Meta-analysis showed that compared with the control group, the semaglutide group was reduced more significantly in body weight (MD = −7.49, 95% CI [−9.92, −5.07], P < 0.001), body mass index (MD = −3.35, 95% CI [−4.79, −1.92], P < 0.001), waist circumference (MD = −7.26, 95% CI [−9.94, −4.58], P < 0.001)...
