A type 2 diabetes meal plan to bring your A1C down
Reviewed by the JForH team ·
To lower your A1C, fill half your plate with non-starchy vegetables, a quarter with protein and a quarter with high-fiber carbs, eat at regular times, and drink water instead of sugary drinks. In studies cited by the American Diabetes Association, nutrition therapy with a registered dietitian lowered A1C by about 0.3 to 2.0 percentage points in type 2 diabetes. Results vary, and if you take insulin or a sulfonylurea, plan changes with your care team to avoid low blood sugar.
What should I eat to lower my A1C?
Build each meal on the Diabetes Plate: half vegetables, a quarter protein, a quarter carbs. The American Diabetes Association (ADA) and the CDC both teach it.
Take a 9-inch dinner plate. That's about the length of a business envelope. Then fill it like this:
- Half with non-starchy vegetables: salad greens, broccoli, green beans, cabbage, peppers, tomatoes, okra.
- A quarter with lean protein: chicken, fish, eggs, tofu, beans or lentils, lean beef or pork.
- A quarter with carbohydrate foods: whole grains, brown rice, a tortilla or roti, potatoes, corn, fruit, milk or yogurt.
Drink water or another zero-calorie drink with it. A study cited in the ADA Standards found the plate method and carb counting both helped people lower their glucose. So you don't have to count grams to make progress.
Here's what that looks like at breakfast. Instead of a glazed doughnut and sweet coffee, try two scrambled eggs with spinach and one slice of whole-wheat toast, with your coffee unsweetened.
What carbs can you eat with type 2 diabetes?
You can eat carbs. Choose whole, high-fiber ones and keep the portion steady from meal to meal.
Carbs raise blood sugar more than anything else you eat, so both the amount and the kind matter. The ADA Standards of Care favor non-starchy vegetables and whole, minimally processed foods, and say to limit added sugars and refined grains. In practice:
- Choose whole grains (oats, brown rice, whole-wheat bread, barley) over white bread and white rice.
- Eat beans, lentils and peas often. You get fiber and protein in the same bite.
- Eat the whole fruit instead of drinking juice.
- Keep your carb amount about the same at each meal. The CDC says this helps keep blood sugar steady.
Should I cut carbs to lower my A1C?
It helps some people. The ADA suggests some adults with diabetes consider eating fewer carbs to improve glucose. Very-low-carb eating (under 26% of calories) lowered A1C in the short term, under 6 months. After a year, the gap with other ways of eating had shrunk. The best plan is the one you can stick with.
How much protein should a diabetic eat at each meal?
About a palm-sized portion, or a quarter of your plate, works for most people. Protein keeps you full longer and slows how fast carbs reach your blood. If you have kidney disease, ask your doctor or dietitian how much is right for you.
Does the order you eat your food change your blood sugar?
It seems to. In a small 2015 study in Diabetes Care, 11 adults with type 2 diabetes ate the same meal on two different days.
When they ate the vegetables and protein first and the bread and juice last, their blood sugar was about 29% lower at 30 minutes, 37% lower at 60 minutes and 17% lower at 2 hours than when they ate the carbs first. A later study in people with prediabetes found a similar pattern.
These were short studies. Think of it as a free habit to try, not a treatment on its own. At dinner, eat your salad and chicken before you start on the rice.
Does walking after meals lower blood sugar?
Yes, for many people. In a 2016 study of 41 adults with type 2 diabetes, a 10-minute walk after each main meal cut the rise in blood sugar after meals by about 12%. That was compared with one 30-minute walk at another time of day. After the evening meal, the drop was about 22%.
A 2022 review of several studies found that light walking breaks lowered blood sugar after meals more than sitting or standing. The ADA advises getting up from long periods of sitting at least every 30 minutes. A loop around the block after dinner counts.
If you have heart disease, joint problems or trouble with balance, ask your doctor what kind of activity is safe for you.
Does it matter what time I eat?
Yes. Regular meals help prevent both highs and lows, according to the CDC. Try to eat at about the same times each day. Don't skip meals if you take a medicine that can cause low blood sugar.
What drinks are good for diabetics?
Water is best. Unsweetened iced tea, coffee and sparkling water are fine too. Regular soda, sweet tea, juice and sports drinks raise blood sugar fast.
If you drink alcohol, talk to your care team first. It can cause lows in people who take insulin or sulfonylureas.
What does a 7-day type 2 diabetes meal plan look like?
Here's a sample week. It's an example, not a prescription. Your portions depend on your size, how active you are and your medicines. Use the plate method for lunch and dinner.
| Day | Breakfast | Lunch | Dinner | Snack |
|---|---|---|---|---|
| Monday | Oatmeal with walnuts and berries, coffee | Turkey and vegetable soup, side salad | Baked salmon, roasted broccoli, small baked potato | Plain Greek yogurt |
| Tuesday | 2 scrambled eggs with spinach, 1 slice whole-wheat toast | Grilled chicken salad with chickpeas and olive oil dressing | Turkey chili with beans, green salad | Apple with peanut butter |
| Wednesday | Plain Greek yogurt with sliced strawberries and almonds | Tuna salad on whole-grain bread, carrot and celery sticks | Chicken stir-fry with lots of vegetables, half cup brown rice | Handful of almonds |
| Thursday | Whole-grain toast with avocado and an egg | Leftover chili, side of cucumber salad | Pork tenderloin, green beans, half cup sweet potato | String cheese and cherry tomatoes |
| Friday | Veggie omelet, small orange | Lentil soup, mixed green salad | Grilled shrimp, zucchini and peppers, small corn tortilla | Hummus with bell pepper strips |
| Saturday | Cottage cheese with peaches (canned in water) | Black bean and vegetable bowl with salsa | Roast chicken, collard greens, half cup brown rice | Popcorn, 3 cups air-popped |
| Sunday | Whole-wheat pancakes (small), eggs, berries | Chicken and vegetable wrap in a whole-wheat tortilla | Baked cod, roasted cauliflower, green salad, small whole-grain roll | Pear with a few walnuts |
Can I still eat rice and roti with diabetes?
Yes. Keep them to a quarter of the plate and fill the rest with dal and sabzi. The ADA notes that standard programs haven't worked as well for some South Asian adults, and that plans built around their own food and culture may help. You don't have to give up your food.
- Rice: keep it to a quarter of the plate, or mix white rice half and half with cauliflower rice or vegetables. Brown rice is a good option.
- Roti: one or two thin whole-wheat roti instead of three or four. Add besan (chickpea flour) to the dough for more protein and fiber.
- Dal: a strong choice. Make it thick, and count it as your protein, not as a side for more rice.
- Sabzi: fill half the plate with non-starchy sabzi like bhindi, lauki, palak or gobi. Go easy on potato sabzi and on ghee or oil.
- Chai: cut the sugar a little at a time, and skip the biscuits and namkeen with it.
Can I eat tortillas, rice and beans with diabetes?
Yes. Make the beans the bigger part of the plate and keep tortillas to one or two.
- Tortillas: choose corn tortillas, which are usually smaller, and keep to one or two.
- Rice and beans: beans the bigger part, rice the smaller part. Use whole beans instead of refried beans made with lard.
- Plantains: boiled or baked instead of fried. A small portion counts as your carb.
- Vegetables: nopales, calabacitas, cabbage, pico de gallo and salads can fill half the plate.
- Drinks: swap aguas frescas and regular soda for water with lime or unsweetened agua de jamaica.
Can I eat grits and cornbread with diabetes?
Yes, in smaller portions, and counted as the carb on your plate.
- Grits: a half cup, ideally stone-ground, with eggs and greens rather than biscuits and gravy.
- Cornbread: one small piece instead of two, and count it as your carb.
- Greens: collards, turnip and mustard greens are excellent. Cook them with smoked turkey or onion instead of fatback.
- Fried foods: oven-fry or air-fry chicken and fish.
- Sweet tea: switch to unsweetened, or cut the sugar down over a few weeks.
How fast can I get my A1C down with diet?
You'll usually see the change at your next A1C test, about 3 months later. A1C reflects your average glucose over roughly that long, so it can't move overnight.
How much it drops varies. In studies cited by the ADA, nutrition therapy with a registered dietitian lowered A1C by about 0.3 to 2.0 percentage points in people with type 2 diabetes. Losing weight helps too. The ADA advises losing at least 5% to 7% of your weight if you have overweight, and notes that at least 5% is needed to see glucose benefits. Results vary from person to person.
Is it safe to change my diet if I take insulin or glipizide?
Yes, but plan it with your doctor first. Eating fewer carbs or walking more while on insulin or a sulfonylurea (such as glipizide, glyburide or glimepiride) can drop your blood sugar too low.
Check your glucose more often when you start. Never stop or change a medicine on your own. Signs of low blood sugar include shaking, sweating, a fast heartbeat, confusion and hunger.

Common questions
What is the best meal plan to lower A1C?
There's no single best plan. The ADA plate method, with half non-starchy vegetables, a quarter protein and a quarter high-fiber carbs, is an evidence-based place to start, and it works with your own foods.
How fast can diet lower my A1C?
A1C reflects about 3 months of blood sugar, so the change usually shows at your next test about 3 months later. Results vary.
How much can A1C drop with diet alone?
In studies cited by the ADA, nutrition therapy with a registered dietitian lowered A1C by about 0.3 to 2.0 percentage points in people with type 2 diabetes.
Do I have to give up rice, roti or tortillas?
No. Keep them to about a quarter of your plate, choose whole-grain versions when you can, and fill half the plate with vegetables.
Should I eat vegetables before carbs?
Small studies found that eating vegetables and protein before carbs lowered the rise in blood sugar after a meal. It costs nothing to try.
How long should I walk after eating?
In one study, a 10-minute walk after each main meal lowered blood sugar after meals more than one longer walk at another time. Ask your doctor what's safe for you.
Is a low-carb diet safe if I take insulin?
It can be, with your care team's help. Cutting carbs while on insulin or a sulfonylurea can cause low blood sugar, so your doses may need to change.
What drinks are best for diabetes?
Water, unsweetened tea, coffee and sparkling water. Skip regular soda, sweet tea and juice.
