The Claim

In non-diabetic adults with overweight or obesity, administration of once-weekly semaglutide at a dose of 2.4 mg over 68 weeks results in a mean reduction of fat mass by 13.2 kg and visceral fat by 0.25 kg, with a relative increase in lean body mass proportion despite an absolute decrease, indicating a preferential loss of fat over lean tissue.

In plain English

If you're an adult with extra weight but don't have diabetes, taking a weekly 2.4 mg shot of semaglutide for about a year and a half can help you lose around 13 kg of fat, including some deep belly fat, while mostly keeping your muscle — even though you might lose a little muscle too, the fat loss is much bigger.

What the research says

1 study
  1. Study: Once-Weekly Semaglutide in Adults with Overweight or Obesity.

    The study tested the same drug and found big weight loss, but it didn’t measure how much was fat or muscle, so we can’t say if the specific numbers in the claim are right.
