Study identifies weight-loss threshold for heart health in patients with obesity, diabetes

(Cleveland Clinic) A Cleveland Clinic study shows that 5 to 10 percent of surgically induced weight loss is associated with improved life expectancy and cardiovascular health. In comparison, about 20 percent weight loss is necessary to observe similar benefits with a non-surgical treatment. The findings also show that metabolic surgery may contribute health benefits that are independent of weight loss. The study is published in the October issue of Annals of Surgery.
