Potential participants can be referred by a health care provider or self-refer if they meet the eligibility criteria. Many programs also use tools like the CDC/ADA Prediabetes Risk Test and community screenings to identify people who could benefit from joining.

The National DPP lifestyle change program focuses on preventing or delaying type 2 diabetes in people with prediabetes or at high risk, before a diagnosis occurs. Diabetes Self-Management Education and Support (DSMES) is for people who already have diabetes and need ongoing education and support to manage their condition day to day.cdc+3​

On average, people with prediabetes who complete the program and achieve modest weight loss through healthier eating and increased activity reduce their risk of developing type 2 diabetes by about half. Many participants also report more energy, better understanding of nutrition and physical activity, and improved overall health.cdc+1​

Sessions are led by trained Lifestyle Coaches, who may be health professionals or other trained staff experienced in supporting behavior change. Coaches guide participants through the curriculum, foster a supportive group environment, and help each person apply strategies in their everyday life.

The National DPP lifestyle change program can be offered in person, online, through distance-learning (like virtual classes or telehealth), or in a combination of these formats. All delivery modes follow a CDC-approved curriculum and are led by trained Lifestyle Coaches who facilitate group discussion, provide support, and help participants set realistic goals.cdc+1​

Participants learn practical ways to eat healthier, become more physically active, manage stress, problem-solve barriers, and stay motivated over time. The curriculum is based on the original Diabetes Prevention Program research trial and follow-up studies, which demonstrated that lifestyle changes can significantly delay or prevent type 2 diabetes.cdc+2​

The Lifestyle Change program lasts one full year. During the first 6 months, participants usually attend at least 16 weekly sessions; in the second 6 months, they attend at least 6 sessions, often held monthly, to maintain progress and build long-term habits.cdc+1​

The program is designed for adults 18 and older who have prediabetes or are at high risk for type 2 diabetes but do not yet have type 1 or type 2 diabetes. Participants typically have a body mass index (BMI) of 25 or higher (23 or higher for Asian Americans) and either qualifying blood test results, a history of gestational diabetes, or a positive score on the CDC/ADA Prediabetes Risk Test.
