People with obesity and another health issue who got a weekly shot of semaglutide plus behavioral therapy lost about 17 kg on average after a year and a half — way more than those who got a placebo.

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.

Taking a weekly injection called semaglutide along with healthy eating and exercise can help people with obesity or overweight lose about 15% of their body weight in a year—much more than people who just take a sugar pill.

In adults with obesity who took weekly semaglutide for one year, most lost at least 5% of their body weight, with many losing 10% or more, and a smaller group losing 20% or more.

When adults with obesity take a drug called semaglutide 2.4 mg for about 1.5 years, nearly 9 out of 10 lose at least 5% of their body weight — compared to only about 1 in 3 to half of those taking a sugar pill or another drug, meaning semaglutide works better for weight loss in most people.

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.
