Diabetes Prevention Programs 

What is the Diabetes Prevention Program? (DPP)

The DPP is part of a growing set of Diabetes Prevention Programs that use an evidence-based year-long lifestyle change program, which provides resources for individuals with a risk for type 2 diabetes to make lasting and healthy lifestyle changes and lose weight.

Entirely too many would-be avoiders of type 2 diabetes think like this: “I’ll eat my way into being at risk, and then just before I get it—X number of years after I’ve been eating the foods that guarantee that I will be diagnosed with it—I’m going to turn things around.” It typically does so without fanfare, a test result dumped in your lap with a thud or a remark from a clinician embedded in your brain during the drive home.

The good news is that there are diabetes prevention programs tailored for just such a moment. They are not about perfection, shame, or eating salads until you die of bitter loneliness. They’re about pragmatic changes you can replicate on your busiest weeks, with the support of not doing it alone.

Eligibility

Patients would have to meet these eligibility criteria to take part in the program:

• 18 years or older
• A body mass index (BMI) of 25 or more (23 or more for Asian individuals)
• Not having type 1 or type 2 diabetes
• Not pregnant

and patients must also satisfy one of the following requirements:

A blood sample that contains one or more of the following:

• Hemoglobin A1C: 5.7–6.4%
• Fasting plasma glucose: 100–125 mg/dL
• Two-hour plasma glucose (75 g of anhydrous glucose dissolved in water): 140 to 199 mg/dL

What diabetes prevention programs actually do (and who they’re built for)

Diabetes prevention programs are well-defined, coached interventions aimed at helping people to reduce their risk for type 2 diabetes. The majority center around sustainable habits—eating patterns you can adhere to, moving regularly, getting better sleep, and problem-solving in real life (travel, stress, family schedules, and holidays).

The best-known program in the United States is the CDC’s National Diabetes Prevention Program. It’s a yearlong program of lifestyle change, delivered with the help of trained coaches and group support. If you are curious about the official information and what “CDC-recognized” means, start with the CDC National Diabetes Prevention Program overview.

So who are these programs for?

• People with prediabetes (often identified by an A1C, fasting glucose, or glucose tolerance test).
• People with a history that raises risk, like gestational diabetes, a strong family history, or certain health conditions.
• People who feel fine today but want a clear plan for diabetes prevention, not vague advice like “eat better and exercise.”

If you are 25 to 45, one-hour programs can be particularly helpful as life is full: career pressure, kids, caregiving, irregular sleep, and takeout on repeat. A good program doesn’t simply ignore those things. It helps you work with them.

A major change in attitude to adopt: Prevention is not a 30-day challenge. Think of adding calories like building a budget instead. You’re not “saving money” once and for all. You establish small habits and continue to push, little by little.

Inside a prediabetes prevention program: what you’ll do week to week

A good resource for preventing pre-diabetes is not predicated on willpower but on whether or not you can duplicate skills. Most programs begin with more frequent sessions (often weekly) and progress to maintenance sessions as habits consolidate.

Here is what “doing the program” can often look like IRL:

You monitor a few basics, lightly. Many plans tout tracking your weight, activity minutes, or eating habits. The aim is not to police yourself. It is to recognize patterns so you can make smarter choices.

You learn specific food skills. Not “good foods and bad foods,” but things like being aware of portions, having simple breakfasts ready to go, building balanced plates, and managing restaurants with no stress.

“You construct the movement to suit your life. You could begin with brief walks, a few strength sessions a week, or what she terms “movement snacks” interspersed between meetings. The program guides you in selecting what’s realistic and then being consistent with it.

You lean on that group support to stay honest. It’s difficult to change habits in a vacuum. In a group, you learn what’s working for others, and you get a reset after a bad week.

A quick snapshot of what you can expect:

Program element	What it feels like	Why it matters
Group sessions	A coach-guided class with discussion	Turns advice into a plan you’ll use
Weekly habit focus	One or two changes at a time	Less overwhelm, more follow-through
Weigh-ins or check-ins	Brief and routine	Builds awareness and accountability
Activity goal	Often walking plus simple strength	Helps insulin work better over time
Maintenance phase	Less frequent sessions	Keeps progress from fading

The habits that move the needle (without turning life upside down)

A balanced meal with protein, fiber, and healthy fats, 

When most people think of “preventing diabetes,” they imagine a life without carbs, joy, or leisure, filled instead with hours at the gym. Good diabetes prevention programs go another way: they’re the sum of small habits that add up, especially if you do them most days.

Food patterns that feel normal

You don’t need a perfect diet. You need a pattern you can keep during busy weeks.

A simple framework: aim for protein, fiber, and color in most meals.

• Protein helps you feel full and can slow how fast a meal raises blood sugar.
• Fiber (beans, lentils, vegetables, fruit, oats, and whole grains) supports steadier blood sugar.
• Color is an easy way to remember plants, which tend to be lower calorie for the volume.

Try one change that doesn’t feel like punishment: Add a high-fiber side (salad, berries, or roasted veggies) before you remove anything.

Movement that’s not all-or-nothing

If your schedule is packed, think of movement like brushing your teeth. It’s not a heroic act. It’s upkeep.

A few approaches that work well in programs: 10-minute walks after meals, two short strength sessions per week, or active commuting when possible. Consistency beats intensity.

Sleep and stress (the quiet drivers)

Bad sleep also can increase hunger signals and make cravings louder. Chronic stress can drive you towards the quick comfort foods and missed workouts, but there are ways to keep it in check. There are programs that discuss these things, and those are worth your time because they address the whole person.

Two “small but real” steps: Set a phone cutoff at 30 to 60 minutes before bedtime, and pick an outlet for stress that you can repeat (walking, journaling, stretching, therapy, prayer, or calling a friend).

And this is the part everyone seems to miss: Lifestyle change sticks when it’s built around your life, not some imaginary 40-hour-a-week version of your week.

How to find a program in the US (and what it may cost)

Picking a program can feel like choosing a gym membership, except it matters more. You want something evidence-based, supportive, and practical.

Start with credibility: look for CDC recognition

A CDC-recognized program meets certain standards for curriculum, coaching, and results tracking. That doesn’t mean it’s perfect for everyone, but it’s a strong filter when you’re comparing options.

If you’re trying to understand what the National DPP includes at a high level, the National DPP overview page gives a clear summary of how it fits into the broader prevention effort.

Online vs in-person: pick what you’ll attend

In person, the programs can seem more personal and create a strong sense of community. Online workouts can be more convenient if you travel, work late, or have kids at home.

Ask yourself one humble question: “Which format will I show up for when I’m tired?”

Cost and coverage: don’t assume you have to pay full price

Coverage varies. Some employers cover diabetes prevention programs through wellness benefits. Some insurers offer coverage or discounts. Community health centers and YMCAs may offer lower-cost options.

If you or a family member is on Medicare, it’s worth reading the eligibility details for the Medicare Diabetes Prevention Program benefit. Even if it doesn’t apply to you today (most readers here are younger), it’s useful context for parents and older relatives who might be eligible.

Questions to ask before you enroll

Keep it simple. Ask:

• How often are sessions, and what happens if I miss one?
• Is there a trained lifestyle coach, and can I message them between sessions?
• What does tracking look like (and is it flexible)?
• Is the program tailored for cultural food preferences?
• How do you support strength training, sleep, and stress, not only with food?

If you’re a clinic, employer, or community group looking at programs at a systems level, the ADCES diabetes prevention program resource can also help explain what quality programming includes.

Conclusion: A program is a plan you don’t have to hold alone

If you’ve been labeled at risk, it’s easy to feel as though you’re walking a tightrope without a net. Diabetes prevention programs provide that net and more: a pathway to follow, a coach, and people who get it. Begin with one next step this week: request an A1C test if you haven’t had one and then look for a CDC-recognized option that you will actually attend. The point is not the perfect life; it’s that diabetes prevention needs to work on messy days too.
