Key Points
- Prediabetes can be reversed with diet and lifestyle changes
- The goal is to balance lean proteins, healthy fats, and high-fiber carbohydrates rather than eliminate entire food groups
- Meal consistency and smart carb pairing help prevent blood sugar spikes and improve insulin sensitivity
- Diabetes diets like the Diabetes Plate method, the Mediterranean Diet, DASH diet, and more can help prevent or delay type 2 diabetes
Learning you have prediabetes can be jarring. It's a sign that your body is not processing blood sugar as efficiently as it should. While it’s not dangerous, it is an early warning sign on the road to type 2 diabetes.
“Here’s the good news,” says Registered Dietitian, Rita Faycurry, RD. “A prediabetes diagnosis is not a life sentence. It can serve as a powerful wake-up call to make diet and lifestyle changes for your health.”
This guide will walk you through the foods to eat and avoid (or limit) if you have prediabetes. You also get a practical 7-day meal plan to help you get started.
What is prediabetes?
Prediabetes means your blood sugar levels are higher than usual but not yet in the type 2 diabetes range. Think of it like a car’s gas light—it’s an indicator that a change is needed before you run into trouble.
Prediabetes is an early sign of insulin resistance. Insulin is the hormone that moves sugar from your blood into your cells for energy. If you are insulin resistant, your cells may not respond well to insulin, and blood sugar builds up in your system instead of being used for energy.
What you eat can make a big difference in preventing diabetes.
Diet to reverse prediabetes
A diabetes diet that focuses on balanced meals with whole foods can lower blood sugar levels to a normal range. In fact, studies show that lifestyle changes, especially diet, can delay or prevent type 2 diabetes by almost 60%.
But what do you eat? And how do you structure your meals? Here’s how to begin.
What to eat for prediabetes: Your food list
Manage prediabetes with diet by choosing foods that help keep your blood sugar levels stable. Instead of a long list of rules, it helps to focus on the variety of foods that can help you limit those blood sugar spikes.
The list of foods below is a guideline to help you establish the foundation of a prediabetes diet.
Foods to focus on
For prediabetes, eat foods rich in fiber, protein, and healthy fats, which slow down digestion and control blood sugar levels, including:
- Non-starchy vegetables: Broccoli, spinach, kale, bell peppers, cucumbers, tomatoes, asparagus, Brussels sprouts, cauliflower
- Lean proteins: Skinless chicken or turkey, fish (like salmon and tuna), eggs, beans, lentils, tofu
- Healthy fats: Avocado, nuts (almonds, walnuts), seeds (chia, flax, pumpkin), olive oil
- High-fiber, complex carbs: Quinoa, brown rice, old-fashioned oats, whole-wheat bread and pasta, sweet potatoes, barley
- Whole fruits: Berries, apples, oranges, and grapefruit are great. Other fruits, such as kiwi, pear, bananas, and grapes, are also acceptable, but in moderation due to their high sugar content. Pairing fruit with a protein or fat source (like an apple with almond butter) can help with blood sugar spikes
- Dairy: Plain Greek yogurt, low-fat milk, and cottage cheese. You can also enjoy cheese that is not highly processed (in moderation, since cheese is high in salt and fat)
Foods to limit
You don't have to eliminate any foods or food groups entirely if you don’t want to, but moderation is key to managing prediabetes.
Faycurry, RD, says, “While it’s best to avoid sugary drinks and ultraprocessed foods and limit refined carbs, we know that's easier said than done. Fortunately, it's entirely possible to enjoy these foods while keeping them as occasional treats instead of making them a daily staple.”
- Sugary drinks: Soda (even diet soda), sweetened iced tea, fruit juice with added sugar, sports drinks, smoothies with added sugar
- Refined carbohydrates: White bread, white rice, pastries, cookies, crackers made with white flour
- Ultraprocessed foods: Packaged snacks, fast food, frozen meals high in sodium and unhealthy fats, processed meats (like bacon and sausage). Studies show they are linked to a higher risk of prediabetes and diabetes
- Sweets and desserts: Candy, cake, ice cream, and other sugary treats
- Fried foods: French fries, fried chicken, and other deep-fried items
Knowing what to eat is the first step; what also matters is how you structure your meals each day.
💡How to build a prediabetes meal plan
Knowing what foods to eat is the first step. Here are a few simple strategies to combine those foods for the best results.
1. Balance with the power trio
Ideally, each meal should have a source of lean protein, high fiber, and small amounts of healthy fat. This combination has been proven to slow down digestion and prevent blood sugar spikes from eating carbs alone.
2. Pair your carbs wisely
“You don't need to fear carbohydrates or go ‘no-carb' if you don’t want to,” says Faycurry, RD. “However, there are ways to consume them to control blood sugar levels. Carbs do better with their friends: dietary fiber, protein, and healthy fats. Try to give your carbs some fiber or fat to mitigate some of their effect on blood sugar.”
Here are some examples:
- Avocado or eggs with toast
- Grilled chicken breast or a side salad before your pasta
- Whole veggies in your pasta, like spinach, mushrooms, zucchini, or bell peppers
- Apple slices with a spoon of peanut butter
- Crackers with cheese
- Sliced strawberries and a handful of chopped almonds on vanilla ice cream
- Greek yogurt with banana slices
3. Use the Diabetes Plate method
The Diabetes Plate method, created by the American Diabetes Association (ADA), is a simple visual guide that divides your plate into portions:
- Half with non-starchy vegetables
- A quarter with lean protein
- A quarter with high-fiber carbohydrates
4. Stay consistent with timing
If you find your blood sugar dipping too low between meals, try eating well-proportioned meals or snacks every 3 to 5 hours, rather than three large meals. This prevents your blood sugar from dipping too low, which can trigger intense cravings and lead to overeating.
Your 7-day prediabetes meal plan
This sample meal plan is designed to be a starting point. Remember:
- Feel free to swap meals and adjust portion sizes based on your hunger levels and preferences
- Herbs and spices can be a great way to add bursts of flavor and interest without adding excess sugar, salt, or unhealthy fats
Day 1
Breakfast: Steel-cut oats with berries and cinnamon. Cook ½ cup of steel-cut oats in water, then top with ½ cup of mixed blueberries and strawberries, 1 tablespoon of chopped walnuts, and a sprinkle of cinnamon. The cinnamon helps with blood sugar control and adds warmth to the dish. You can add a small spoon of honey to sweeten it, if you wish.
Lunch: Mediterranean chicken salad. Large mixed greens salad with 3 oz grilled chicken breast seasoned with oregano, garlic powder, and salt. Mix with cherry tomatoes, diced cucumbers, and bell peppers, and a drizzle of olive oil with a pinch of za'atar spice blend.

Other tips for managing prediabetes
1. Get moving
Exercise improves insulin sensitivity in healthy adults with moderate effect sizes. Even a single bout of exercise can increase insulin sensitivity for 16 hours after the session.
Here are some science-based ways to prevent diabetes with exercise:
- Brief bursts of intense exercise before meals ("exercise snacks") can improve blood sugar control more effectively than one continuous 30-minute session
- 10 bodyweight squats every 45 minutes, for a total of 100 squats a day
- Take a light stroll—even 15 minutes after each meal can help lower blood glucose levels
- Aim for at least 30 minutes of moderate activity five days a week
2. Stay hydrated
Fill your Stanley cup, Hydro Flask, or a regular ol’ water bottle to keep sipping all day. Research shows that drinking more than 1 liter of water per day lowers the risk of high blood sugar. Drinking plain water also helps lower HbA1c levels.
Try to swap your sugary drinks with plain water. If you can’t stand the taste of water, you can consume it in the form of unsweetened herbal teas or flavor it with slices of lemon.
3. Prioritize sleep
Research shows that sleeping fewer than 6.2 hours per night can increase insulin resistance by nearly 15% in women. In the study, postmenopausal women experienced even more severe effects, up to a 20% increase!
Studies in healthy men have also found that getting 5 hours of sleep per night for even just one week significantly reduces insulin sensitivity. Aim for 7-8 hours of quality sleep per night to support healthy blood sugar levels.
4. Lower stress
When you’re constantly stressed, the body releases the stress hormone cortisol, which results in higher blood sugar levels.
Cortisol increases blood glucose levels by:
- Releasing stored glucose from your liver
- Making it harder for insulin to do its job, leading to insulin resistance
Consider finding healthy ways to cope with stress, such as practicing meditation, yoga, or engaging in hobbies you enjoy. Watching something funny or listening to your favorite music are also great stressbusters.
If you are unable to lower your stress levels on your own, consider getting a mental health consultation to get professional support.
Final thoughts: Reversing prediabetes with diet
A prediabetes diagnosis is your body's way of asking for a change. By focusing on a balanced diet rich in whole foods, you can stabilize your blood sugar, improve your body's response to insulin, and significantly reduce your risk of developing type 2 diabetes.
This 7-day plan is a great starting point, but the most effective diet is one you can maintain long-term, based on your needs and preferences.

Frequently Asked Questions (FAQs)
What is the best diet for prediabetes?
There is no single "best" diet for prediabetes. However, effective diabetes diets like the Mediterranean diet or the DASH diet emphasize whole foods: non-starchy vegetables, lean proteins, healthy fats, and high-fiber carbs, while limiting processed foods and sugar.
Some people prefer the keto diet, the carnivore diet, or another type of no-carb diet, which can help regulate blood sugar levels effectively. However, bear in mind that these restrictive diets may be hard to sustain in the long term.
What foods should I avoid if I am prediabetic?
If you have prediabetes, consider limiting foods that cause rapid blood sugar spikes. These include sugar-sweetened beverages (soda, sweet tea, fruit juice), refined grains (white bread, white rice, pastries), and highly processed snacks (chips, cookies, candy).
Can I eat fruit if I have prediabetes?
Dietitian Faycurry, RD, says, “Yes, you can eat fruit if you have prediabetes! Whole fruits are packed with dietary fiber, which helps slow down the absorption of the fruit's natural sugar. Pairing fruit with a protein or fat source, like an apple with peanut butter, is a great strategy to stabilize blood sugar.”
How fast can I reverse prediabetes with diet?
The time it takes to reverse prediabetes with diet varies for each person, but some studies show that significant improvements in blood sugar levels can be seen within 3 to 6 months of making consistent diet and exercise changes.
