  • What can a person do to delay or prevent type 2 diabetes?

    Reduce risk of type 2 diabetes by making healthy changes in your lifestyle. The DPP lifestyle change program is designed to help you learn how to make sustainable healthy lifestyle choices.


  • What is the National DPP?

    The National Diabetes Prevention Program (DPP) is a partnership of public and private organizations that advance type 2 diabetes prevention efforts in the United States. The National DPP was established by the Centers for Disease Control and Prevention (CDC) and provides an evidence-based framework for diabetes prevention lifestyle change programs throughout the United States. 


  • What is the DPP lifestyle change program?

    The DPP is a lifestyle change program that helps participants develop healthy behavior changes to promote weight loss. Regardless of where a person signs up for a CDC-recognized DPP lifestyle change program, the program structure is the same. Groups meet once a week for 16 weeks, then once a month for 6 months to maintain healthy lifestyle changes. During each session, a lifestyle coach will teach a lesson and lead a group discussion. 

    For example, a DPP program participant will learn to eat healthy, add physical activity to their life, manage stress, and stay on track when eating out.

  • What does it mean to be a CDC-recognized DPP program?

    To ensure that participants receive a high quality and impactful program, the CDC sets standards for organizations that offer the DPP program. The standards include a CDC-approved curriculum, capacity, and commitment to offer the program within 6 months of receiving approval, trained lifestyle coaches, and a designated program coordinator.

  • Where can a person participate in a DPP lifestyle change program?

    Learn more about finding a DPP lifestyle change program that works best for your schedule and location. 


  • Does the DPP lifestyle change program really work?

    Yes! In fact, the program can help people with prediabetes cut their risk of developing type 2 diabetes in half. A DPP research study showed that making modest behavior changes helped participants lose five to seven percent of their body weight—that is 10 to 14 pounds for a person weighing 200 pounds. The lifestyle changes reduced the risk of developing type 2 diabetes by 58% in people with prediabetes.


  • Is the DPP lifestyle change program offered in Spanish?

  • Can a person participate if they have diabetes?

    Unfortunately, the program is only for individuals who have not been diagnosed with type 1 or type 2 diabetes. People with diabetes are encouraged to maintain their health by working with a primary care physician or endocrinologist as medically indicated.


  • Can the program be shortened?

    No, the program cannot be shortened. DPP program classes require one hour per week for the first 16 weeks, then one-to-two hours per month for the remainder of the year. To maximize the efficacy of the lifestyle change program, the curriculum requires year long participation.
