Prediabetes Diet: What to Eat, Portions and a Simple Plate
There is no single prediabetes diet. Official guidance points to a way of eating you can keep: half the plate non-starchy vegetables, a quarter protein, a quarter carbohydrate foods, and fewer sugary drinks. Only a lab test can tell you whether you have prediabetes.
What prediabetes is, in one paragraph
Prediabetes means blood sugar is higher than usual but not yet in the diabetes range. The ADA lists an A1C of 5.7% to 6.4% as the prediabetes range, and a clinician can confirm it with a lab test. Many people have it without symptoms. See what an A1C of 5.7 means. This page is not a diagnosis and not a treatment plan.
A simple plate to start with
- Half non-starchy vegetables. Salad, broccoli, peppers, green beans, tomatoes, cauliflower.
- A quarter protein. Fish, chicken, eggs, tofu, beans or lean meat.
- A quarter carbohydrate foods, preferably high in fiber: whole grains, beans, fruit, starchy vegetables.
- Choose water or unsweetened drinks in place of sugary ones.
The CDC describes this plate method as a way to plan meals without counting. See the diabetic meal plan guide for the details and three example weeks.
Foods and habits worth favoring
| Instead of | Consider | Why |
|---|---|---|
| Sugary drinks and juice | Water, sparkling water, unsweetened tea or coffee | Liquid sugar raises glucose fast and does not fill you up |
| Refined snacks | Nuts, plain yogurt, fruit, raw vegetables | More fiber, protein or fat |
| Large portions of white bread, rice or pasta | Measured portions, or beans, oats and other whole grains | Portion and fiber change the effect |
| Eating out of the package | Plating a portion | You see what you eat |
The foods table shows carbs, fiber and glycemic index for 80 common foods, and the carb counter adds up a meal.
Beyond food
The NIDDK points to more than diet for preventing or delaying type 2 diabetes: regular physical activity, enough sleep and steady habits all matter. Ask your clinician what is right for you. The CDC-recognized National Diabetes Prevention Program offers a year-long lifestyle change program with a trained coach, in person or online, for adults who qualify.
Nothing on this site promises to reverse or cure prediabetes, and no supplement or “detox” will. Be cautious of anything that says it will.
Keeping it livable
Small, steady changes tend to last longer than strict rules. Pick one habit, like swapping one sugary drink a day for water, and keep it for a few weeks before adding another. A registered dietitian can help you build a plan around your culture, budget and tastes. Try planning a week in the meal planner, which shows plate balance, carbs and fiber and never sets calorie or weight goals.
Frequently asked questions
What should I eat if I have prediabetes?
There is no single prediabetes diet. Official guidance centers on a pattern of eating you can keep up: vegetables, whole grains, beans, lean protein, healthy fats, and fewer sugary drinks and refined snacks. A registered dietitian can tailor it to you.
Do I have to give up carbs?
No. Carbohydrate foods can stay in your meals. What matters is which ones, in what portions, and what else is on the plate. The plate method is a simple way to start.
Can food alone “fix” prediabetes?
Please be wary of anyone who promises that. Eating habits, physical activity and sleep all play a role, and your clinician can tell you what is right for you. The CDC-recognized lifestyle change program offers structured support.
How do I know if I have prediabetes?
Only a lab test ordered by a clinician can say so. The ADA lists an A1C of 5.7% to 6.4% as the prediabetes range. See the A1C 5.7 page, and ask your clinician about testing.
Is the meal planner OK for prediabetes?
Yes. It shows carbs, fiber, protein and plate balance. It does not set targets or calorie goals, and any numbers you enter are yours.
Information only, not medical advice. Your care team may set different targets for you, and only a lab test ordered by a clinician can diagnose diabetes or prediabetes. See our medical disclaimer.
