How well do weight-loss drugs work?
Prescription weight-loss drugs approved for long-term use (more than 12 weeks) produce significant weight loss compared with placebo. The combination of weight-loss medication and lifestyle changes results in greater weight loss than lifestyle changes do alone.
Over the course of a year, that can mean a weight loss of 3% to 7% of total body weight above that achieved with lifestyle changes alone. That may seem like a modest amount. But a sustained weight loss of 5% to 10% can have important health benefits, such as lowering blood pressure, blood sugar and triglyceride levels.
