The effectiveness of lifestyle intervention for the prevention of type 2 diabetes has recently been demonstrated. Four clinical trials using lifestyle interventions comprised of weight loss, physical activity, and diet have successfully prevented or delayed the onset of diabetes development in high-risk individuals. As we attempt to translate these results from the clinical trial to the community, it is important to understand the various components of the lifestyle intervention efforts used. After a description of the key lifestyle components of these clinical trials is provided, a discussion of possible suggestions for implementing these findings in the broader community setting is presented.
