The NIDDK funded the Look AHEAD (Action for Health in Diabetes) study to evaluate whether weight loss lowered the risk for cardiovascular disease events such as heart attack and stroke—and other health problems—in people who were overweight or obese and had type 2 diabetes. Researchers looked at whether participants could lose weight and keep it off through a lifestyle intervention program involving increased physical activity and healthy eating. Few, if any, studies of this size and length have had similar success in helping participants reach and maintain a significant weight loss.

In the United States, type 2 diabetes is the most common form of diabetes in adults. Type 2 diabetes occurs when people have higher-than-normal levels of blood glucose, also called blood sugar. Over time, high blood glucose increases the risk for serious health problems such as cardiovascular disease, kidney disease, eye disorders, and nerve diseases. Overweight and obesity are linked to higher risks of other diseases and conditions, including type 2 diabetes and cardiovascular disease. Overweight (Body Mass Index [BMI] 25.0-29.9) and obesity (BMI ≥ 30.0) now affect about 70 percent of adult Americans.
