A diabetes prevention program is a structured, year-long lifestyle plan that helps people with prediabetes lower their risk of developing type 2 diabetes. The best-known version is the CDC-led National Diabetes Prevention Program, which pairs you with a trained coach to build steady habits around food, movement, and weight.
A diabetes prevention program is a structured, coach-led lifestyle plan for people at high risk of type 2 diabetes. The flagship example, the CDC-recognized National DPP, runs for about a year and has been shown to cut the risk of developing type 2 diabetes by 58% in adults with prediabetes.
This guide explains what a diabetes prevention program actually is, how well it works, who qualifies, what happens during the program, in-person versus online options, what it costs, and how to find one near you. If you want the broader picture of prevention beyond a formal program, see our guide on how to prevent diabetes.
What Is the Diabetes Prevention Program?
The Diabetes Prevention Program usually refers to the National Diabetes Prevention Program (National DPP) — a public-private effort led by the CDC to deliver a proven lifestyle change program to people at high risk for type 2 diabetes.
It grew out of a major research study, also called the Diabetes Prevention Program, which tested whether structured lifestyle changes could stop or delay type 2 diabetes in people with prediabetes. The results were strong enough that the CDC built a national network of recognized programs to deliver the same approach in real communities.
The heart of it is the lifestyle change program: a year-long, group-based program led by a trained lifestyle coach. It is not a diet, a medication, or a quick fix. It is a guided, gradual process for building habits that lower risk and last.
The two main goals are simple and evidence-based:
- Lose 5% to 7% of your body weight if you are overweight.
- Get at least 150 minutes of physical activity per week, such as brisk walking.
Everything in the program — the coaching, the group support, the tracking — is built to help you reach and keep those two targets.
How Well Does the Diabetes Prevention Program Work?
The evidence behind the diabetes prevention program is unusually strong for a lifestyle intervention.
According to the CDC and NIDDK, the original Diabetes Prevention Program research study found that the lifestyle change approach:
- Reduced the risk of developing type 2 diabetes by 58% in adults with prediabetes.
- Reduced risk by 71% in adults aged 60 and older — an even larger benefit for older participants.
Those reductions came from modest, sustainable changes — losing a small amount of weight and moving more — not from extreme dieting or intense exercise. Follow-up research has shown the protective effect can last for years after the program ends.
This is why a structured program often outperforms going it alone. The accountability, coaching, and group support help people stick with the habits long enough to see results. To understand the science of why these changes work, see our guide on understanding metabolic health.
Who Qualifies for the Diabetes Prevention Program?
The National DPP lifestyle change program is designed for adults at high risk for type 2 diabetes — not for people who already have it. According to the CDC, to be eligible you generally must:
- Be 18 years or older.
- Have a body mass index (BMI) of 25 or higher (or 23 or higher if you are Asian American).
- Not be pregnant.
- Not have a previous diagnosis of type 1 or type 2 diabetes.
In addition, you must meet one of these risk criteria:
- A blood test in the prediabetes range within the past year — an A1C of 5.7% to 6.4%, a fasting blood sugar of 100 to 125 mg/dL, or a 2-hour glucose of 140 to 199 mg/dL.
- A previous diagnosis of gestational diabetes (diabetes during pregnancy).
- A high score on the CDC/ADA prediabetes risk test, which asks about age, weight, family history, and activity level.
If you are not sure where you stand, a simple blood test is the clearest starting point. Our guide on prediabetes treatments explains what those numbers mean and what to do next.
What Happens During the Program?
A year may sound like a long commitment, but the program is paced to make change feel manageable. The CDC structures the lifestyle change program in two phases:
- First 6 months: You meet roughly weekly to start, in at least 16 sessions, learning the core skills — healthy eating, adding activity, managing stress, and problem-solving around setbacks.
- Second 6 months: You meet at least once a month to practice and reinforce those habits so they stick for the long term.
Throughout, a trained lifestyle coach guides the group, and the other participants become a built-in support network. You will typically:
- Track your food, activity, and weight.
- Set small, realistic weekly goals.
- Learn to handle real-life challenges like travel, holidays, and stress eating.
- Celebrate progress and troubleshoot plateaus together.
The focus is on steady habits, not perfection. The coaching and group accountability are what set a structured program apart from trying to change everything on your own.
In-Person vs. Online Diabetes Prevention Programs
The National DPP is delivered in several formats, so you can pick what fits your life. All recognized programs follow the same CDC-approved curriculum and use trained coaches — the difference is mostly in how you attend.
| Feature | In-Person Program | Online / Distance Program |
|---|---|---|
| Format | Group classes at a local site | Live virtual sessions or self-paced online lessons |
| Coach support | Face-to-face with a trained lifestyle coach | Same trained coach by video, phone, or app |
| Group support | In-room peer group | Virtual group chats or forums |
| Schedule | Set class times at a fixed location | More flexible, fits around work and home |
| Availability | Depends on programs near you | Available across the country regardless of location |
| Best for | People who prefer in-person connection and routine | People with busy schedules, travel, or no nearby site |
There is no single "best" format — the right choice is the one you will actually attend consistently. Many people choose online or distance options simply because they are easier to fit into a full schedule.
What Does the Diabetes Prevention Program Cost?
Cost varies by program and location, but the diabetes prevention program is often free or low-cost, especially when it is covered by insurance.
- Medicare: The Medicare Diabetes Prevention Program (MDPP) is a covered benefit. Eligible people with Medicare Part B can join a recognized program at no cost as a once-per-lifetime benefit.
- Private insurance and employers: Many health plans and workplace wellness programs now cover the National DPP. It is worth asking your insurer or HR department directly.
- Medicaid: Coverage varies by state, and a growing number of state Medicaid programs include it.
- Self-pay: Where it is not covered, many community programs are offered free or at a reduced cost through health departments, YMCAs, and health systems.
Because the program is designed to prevent a costly chronic condition, insurers and employers increasingly see value in covering it. Always confirm coverage before you enroll so there are no surprises.
How to Find and Join a Diabetes Prevention Program
Getting started is more straightforward than many people expect:
- Check your risk. Get a blood test or take the CDC/ADA prediabetes risk test to see whether you qualify.
- Find a recognized program. Use the CDC's National DPP program finder to search for in-person and online options.
- Confirm eligibility and coverage. Share your blood test or risk score and check whether Medicare, your insurer, or your employer covers it.
- Enroll and commit to the year. Consistency matters more than intensity — showing up regularly is what drives results.
If a formal year-long program is not the right fit, you can still apply the same evidence-based habits on your own or with other structured support. The most important thing is to start during the prediabetes window, when prevention works best. Our guide on whether diabetes can be reversed covers what is possible once blood sugar is already elevated.
Frequently Asked Questions
What is the Diabetes Prevention Program?
The Diabetes Prevention Program usually means the National Diabetes Prevention Program (National DPP), a CDC-led lifestyle change program for people at high risk of type 2 diabetes. It is a structured, year-long, coach-led program focused on losing a modest amount of weight and getting regular physical activity to lower diabetes risk.
Who qualifies for the Diabetes Prevention Program?
You generally qualify if you are 18 or older, have a BMI of 25 or higher (23 or higher if Asian American), are not pregnant, have no prior type 1 or type 2 diabetes diagnosis, and have either a blood test in the prediabetes range, a history of gestational diabetes, or a high score on the CDC/ADA prediabetes risk test.
How much does the Diabetes Prevention Program cost?
Cost varies, but the program is often free or low-cost. Medicare covers it at no cost for eligible beneficiaries, and many private insurers, employers, and state Medicaid programs cover it as well. Community programs through health departments and YMCAs are frequently free or reduced-cost.
Does Medicare cover the Diabetes Prevention Program?
Yes. The Medicare Diabetes Prevention Program (MDPP) is a covered benefit. Eligible people enrolled in Medicare Part B can join a recognized program at no cost, as a once-per-lifetime benefit, if they meet the eligibility requirements including a recent blood test in the prediabetes range.
How long is the Diabetes Prevention Program?
The lifestyle change program runs for about one year. The first six months include at least 16 sessions, usually starting weekly, and the second six months include at least monthly sessions to reinforce the new habits so they last.
Does the Diabetes Prevention Program really work?
Yes. The original Diabetes Prevention Program research study found the lifestyle change approach reduced the risk of developing type 2 diabetes by 58% in adults with prediabetes, and by 71% in adults aged 60 and older. The benefits came from modest weight loss and regular activity, not extreme dieting.
Is the Diabetes Prevention Program available online?
Yes. Recognized programs are offered in-person, online with live virtual sessions, through self-paced distance learning, or in combination. All formats follow the same CDC-approved curriculum and use trained coaches, so you can choose the option that best fits your schedule.
What is the difference between the National DPP and a diabetes management program?
A diabetes prevention program is for people with prediabetes or high risk who do not yet have type 2 diabetes — its goal is to stop or delay the condition. A diabetes management program is for people already diagnosed with diabetes and focuses on controlling blood sugar and preventing complications.
Next Steps
A diabetes prevention program works because it turns proven habits — modest weight loss, regular movement, and consistent support — into a structured plan you can actually follow. The best time to start is during the prediabetes window, before blood sugar climbs higher.
If you are ready to build those habits with real structure and support, the Done With Diabetes™ program, a type 2 diabetes protocol, offers a lifestyle-first plan for nutrition, movement, and daily routines built for real life. Start Program when you are ready.
