Systematic Review Reveals the Most Effective Method for Losing Weight

Recent scientific reviews show that bariatric surgery is the best way to lose weight for a long time. It can help people keep about 25% of their weight off for up to 10 years. But, not many people use this surgery to treat severe obesity. Lifestyle changes like diet and exercise usually only result in a 7.4% weight loss, which is often regained. New drugs like GLP-1s are promising, with one causing a 21.1% weight loss. Metabolic and bariatric surgeries like gastric bypass also show significant weight loss percentages.

Studies suggest that these treatments should be considered earlier in the disease process to better fight the obesity epidemic. Experts say that using these treatments sooner could help more people avoid severe obesity. While lifestyle changes are helpful, they often aren’t enough on their own. Combining surgery or new medications with healthy habits might be the best way to achieve lasting weight loss.
