Although people with diabetes can prevent or delay complications by keeping blood glucose levels close to normal, preventing or delaying the development of type 2 diabetes in the first place is even better. The results of a major federally funded study, the Diabetes Prevention Program (DPP), show how to do so. This study of 3,234 people at high risk for diabetes showed that moderate diet and exercise resulting in a 5- to 7-percent weight loss can delay and possibly prevent type 2 diabetes.

Study participants were overweight and had higher than normal levels of blood glucose, a condition called pre-diabetes (impaired glucose tolerance). Both pre-diabetes and obesity are strong risk factors for type 2 diabetes.

Am I at Risk for Type 2 Diabetes?
Because of the high risk among some minority groups, about half of the DPP participants were African American, American Indian, Asian American, Pacific Islander, or Hispanic American/Latino. The DPP tested two approaches to preventing diabetes: a healthy eating and exercise program (lifestyle changes), and the diabetes drug metformin. People in the lifestyle modification group exercised about 30 minutes a day 5 days a week (usually by walking) and lowered their intake of fat and calories. Those who took the diabetes drug metformin received standard information on exercise and diet. A third group received only standard information on exercise and diet.

The results showed that people in the lifestyle modification group reduced their risk of getting type 2 diabetes by 58 percent. Average weight loss in the first year of the study was 15 pounds. Lifestyle modification was even more effective in those 60 and older. They reduced their risk by 71 percent. People receiving metformin reduced their risk by 31 percent.
