DPP intervention was effective in reducing weight and risk for diabetes among older adults. The Diabetes Prevention Program (DPP) clinical trial conclusively demonstrated that participation in an intensive behavioral lifestyle intervention consisting of nutrition, physical activity, and behavioral counseling was more effective in reducing the incidence of type 2 diabetes and producing clinically significant weight loss than were metformin or placebo. Participants on average lost 6.8 kg and more than one-third lost 7% or more of their initial weight at one year follow-up. DPP was particularly effective among participants age 60 and older, in which there was a 71% reduction in the incidence of diabetes compared to 58% in the larger sample (mean age of 51).
