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.

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.

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.

Taking a weekly shot called semaglutide 2.4 mg helps people who are overweight and have prediabetes lose a lot of weight—about 15 kg in a year—and even after stopping the shot, they still keep off nearly 9 kg. This also helps stop them from developing full-blown diabetes.
