Once-weekly subcutaneous semaglutide 2.4 mg induces significant weight loss (average 14.9% body weight) in non-diabetic adults with overweight or obesity compared to placebo.
If you have obesity and do not have diabetes, a once-weekly injection of semaglutide (2.4 mg) is a highly effective medical treatment that can lead to an average 15% reduction in body weight over 16 months. This is significantly more effective than placebo and addresses the biological drive to regain weight that often limits lifestyle changes alone.
Participants receiving semaglutide lost an average of 14.9% of body weight, compared to 2.4% in the placebo group over 68 weeks.
