Methods: The investigators will use a cluster randomized trial design. The investigators will allocate groups of eligible Veterans from ZVAMC to either a MOVE OUT invitation or a standard MOVE! invitation. The investigators will use clinically gathered weight data to determine overall rates of weight loss in the randomly assigned Veterans. In addition, the investigators will recruit a sample of Veterans from each randomized group to participate in a study of the effectiveness of the weight management program to which they are assigned. The investigators will use established methods to assess changes in diet, exercise and attitude, as well as physiologic outcomes including weight, blood pressure, Hemoglobin A1c, and lipid values. The investigators will use qualitative methods to learn what aspects of the two programs are most effective.
