Adherence
A community-delivered, group-based lifestyle intervention adapted from the Diabetes Prevention Program (YDPP) delivered by the YMCA produces meaningful weight loss (2.3 kg mean difference vs. standard care) in low-income, high-risk adults with prediabetes, demonstrating that lower-cost, scalable models can achieve results comparable to intensive clinical trials.
If you are at risk for type 2 diabetes, look for a free, community-based lifestyle program like the YMCA Diabetes Prevention Program. It involves weekly group sessions focusing on walking 150 minutes a week and eating less fat. You don't need expensive equipment or one-on-one coaching; the group support and structured lessons help you lose about 5 pounds on average, which is enough to significantly lower your risk.
This large, community-based, comparative effectiveness trial demonstrates that adults at high risk for type 2 diabetes achieve a 2.3-kilogram (approximately 5 lbs) lower mean body weight after 12 months if they are simply offered a lifestyle intervention adapted from the DPP and delivered by the YMCA.
