Taking a weekly semaglutide shot (2.4 mg) for about a year helps people with extra weight feel more physically capable and improves their overall quality of life—more than a dummy pill would.
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.
When a drug like semaglutide turns on certain brain and body signals, it helps people feel fuller, eat less, and lose about 15% of their body weight on average.
A weekly shot called semaglutide helped people with extra weight lose nearly 6 inches off their waist over a year and a half, much more than a fake treatment did — which means it may really help reduce belly fat and lower heart and metabolic disease risks.
People without diabetes who are overweight or obese and take a weekly 2.4 mg dose of semaglutide often get mild stomach issues like nausea, diarrhea, or vomiting, but most keep taking it — only a small number stop because of these side effects.
