The Claim

Treatment with once-weekly semaglutide combined with lifestyle intervention for 12 weeks in overweight/obese adults is associated with significant reductions in absolute fat mass across all body regions (android, gynoid, arms, legs), with the greatest relative reduction occurring in the android (abdominal) region, indicating a preferential loss of central fat.

In plain English

Overweight or obese adults who take a weekly semaglutide injection and follow a lifestyle program for 12 weeks lose fat from all body areas, with the most fat loss happening in the belly area.

See the scientific wording

Treatment with once-weekly semaglutide combined with lifestyle intervention for 12 weeks in overweight/obese adults is associated with significant reductions in absolute fat mass across all body regions (android, gynoid, arms, legs), with the greatest relative reduction occurring in the android (abdominal) region, indicating a preferential loss of central fat.

Why this might work

Semaglutide activates receptors on fat cells, increasing fat breakdown. It also acts on brain receptors to reduce appetite, creating an energy deficit. Because belly fat cells have more receptors and higher metabolic activity, they release more fat than other areas. This leads to the greatest percentage of fat loss from the belly.

1 study
  1. Study: Effects of once-weekly semaglutide on regional body composition in overweight or obese adults

    The study shows that people lost fat from their belly, hips, arms, and legs, but it didn't measure whether they lost a bigger percentage of belly fat compared to other areas; it only showed the actual pounds lost, which was less in the belly than in the hips and legs.
