The chart below compares the long-term effectiveness of four different obesity treatments: diet and exercise, weight loss medications and bariatric surgery.
- Bariatric surgery clearly has the best weight loss outcome compared to the other two treatments — 50 to 70 percent of people were able to lose at least 50 percent of the excess weight and keep it off for five years.
- After five years, only 2 to 5 percent of the people who dieted and exercised had maintained a weight loss of at least 10 percent.
- People who had taken weight loss medications were not able to maintain any weight loss.
