Purpose The purpose of this study was to identify effective strategies for sustained weight management used by African American patients with obesity and type 2 diabetes. Methods In this study, nominal group technique was used to identify effective strategies for weight management used by 12 African Americans with overweight/obesity and type 2 diabetes who successfully lost or maintained their weight after completing DECIDE (Decision-making Education for Choices In Diabetes Everyday), a 9-module, literacy-adapted diabetes and cardiovascular disease (CVD) education and problem-solving training program. Results Participants generated a list of 101 strategies that covered 4 domains: nutrition, physical activity, cognitive-behavioral strategies, and other. Self-monitoring and relying on social support were the top 2 strategies for weight maintenance. Conclusion Future obesity studies should consider including friends/family as well as electronic tools to facilitate self-monitoring and regular practice of behavioral strategies for long-term success.
