Community Preventive Services Task Force recommends combined diet and physical activity promotion programs for persons at increased risk for type 2 diabetes on the basis of strong evidence of effectiveness in reducing new-onset diabetes. Combined diet and physical activity promotion programs also increase the likelihood of reversion to normoglycemia and improve diabetes and cardiovascular disease risk factors (weight, blood glucose levels, blood pressure, and lipid levels). These programs are effective across a range of counseling intensities, settings, and implementers. Programs commonly include a weight-loss goal, individual or group sessions (or both) about diet and exercise, meetings with a trained diet or exercise counselor (or both), and individually tailored diet or exercise plans (or both). Higher-intensity programs lead to greater weight loss and reduction in new-onset diabetes. Economic evidence indicates that such programs aimed at preventing type 2 diabetes among persons at increased risk are cost-effective.
