The Claim

In non-diabetic adults with overweight or obesity, once-weekly subcutaneous semaglutide at a dose of 2.4 mg, when combined with lifestyle intervention, results in a mean body weight reduction of 14.9% over 68 weeks, which is 12.4 percentage points greater than placebo plus lifestyle intervention, with 86.4% of participants achieving at least 5% weight loss and 50.5% achieving at least 15% weight loss, indicating clinically meaningful and sustained efficacy.

In plain English

For adults who aren't diabetic but carry extra weight, a weekly injection of semaglutide (2.4 mg) plus healthy lifestyle changes led to nearly 15% weight loss over a year and a half—way more than lifestyle changes alone.
