Anticipated Impacts on Veteran's Healthcare: Weight management is an important focus of VA as evidenced by its VA/DoD Clinical Practice Guideline and MOVE! program targeting overweight/obesity. VA is also committed to using group visits to increase the efficiency and effectiveness of health care delivery. The investigators aim to test a novel intervention that combines intensive weight and diabetes management using the SMA platform. This research addresses important missions to VA because diabetes is more prevalent in Veterans than in the general population, and because weight management is more challenging and complex in patients with diabetes. Project Background: SMAs involve groups of patients who share a common chronic condition and meet over time to receive education, self-management enhancement, and medication management to improve clinical outcomes. A systematic review by VA found that SMAs modestly improve glycemia in patients with diabetes. Although these SMA programs sometimes included diet and physical activity counseling, weight management was not a primary goal, and weight typically was not reduced. Instead, medication intensification was the primary strategy for improving glycemia, and this strategy can lead to weight gain.
