What you eat can help you avoid the problems that often accompany a diagnosis of prediabetes. You might even be able to reverse prediabetes!

What is prediabetes?

Prediabetes is more than just a blood sugar problem. It’s a metabolic disorder that’s measured and defined by elevated blood sugar levels. But high blood sugar isn’t the only problem associated with prediabetes, so it can’t be the only one that we treat.

Other problems associated with prediabetes

  • fatty liver
  • high blood pressure
  • low levels of chronic inflammation
  • high triglyceride levels
  • low levels of HDL-cholesterol
  • abdominal obesity
  • increased blood clotting
  • blood vessel dysfunction,
  • increased risk for some forms of cancer
  • double to quadruple risk of heart disease.

So the best prediabetes diet must address more than just blood sugar levels.

Low carb is not for me

A lot of people swear off carbs when they receive a prediabetes diagnosis. I don’t favor them, but low-carb diets can help manage blood sugar levels. As a registered dietitian nutritionist, I take a more holistic view of eating. I want my diet to boost my overall health. So healthy eating for prediabetes has to mean healthy eating for overall health too. I care about inflammation, blood vessel health and all the problems associated with prediabetes listed above.

Instead of putting emphasis on carbs (or fat or protein, for that matter), I put emphasis on health-boosting foods. So much evidence tells us that wholesome carbohydrate-containing foods increase wellbeing and longevity. To me then, the best prediabetes diet is one that includes mostly wholesome foods, tastes good, is satisfying and helps to manage the insulin resistance that’s largely behind prediabetes and type 2 diabetes.

  • This field is for validation purposes and should be left unchanged.


Just fyi: Both prediabetes and type 2 diabetes involve loss of insulin-producing capacity in the presence of insulin resistance. Also fyi: I typically recommend carb-counting for diabetes, but not usually for prediabetes. That’s because if you have prediabetes, you are not at risk for very high blood sugar levels like you might be with diabetes.

What is the best prediabetes diet?

Science hasn’t yet – and probably never will – identify a single best diet for prediabetes. Fortunately, there’s more than one way to slow the progression from prediabetes to type 2 diabetes. Here are 5 keys to your best prediabetes diet.

  1. Plant-slant on your plate. When you focus on wholesome foods from the plant kingdom, you’re chowing down on lots more than just vitamins, minerals and fiber: You’re treating yourself to a diet rich in disease-fighting phytonutrients. In a long-term study, researchers found that moderately reducing animal foods was associated with less risk for type 2 diabetes. But the greatest protection – a 34% risk reduction – came from a diet built around mostly wholesome plants. It wasn’t necessary to omit all animal foods. That’s great news for me because my day without dairy or my week without seafood and eggs would be very sad indeed!
  2. Eat fruit. The best prediabetes diet doesn’t omit fruit. Yes, fruit contains carbohydrates, but it’s packed with health-shielding nutrients and phytonutrients. In general, eating fruit is associated with less chronic disease. Research identifies berries, in particular, as good choices for diabetes prevention.

    Citrus fruits offer important viscous fibers.

  3. Eat as if you live near the Mediterranean Sea. Healthy eating for prediabetes looks a lot like a Mediterranean-style diet. A large meta-analysis of 10 studies involving more than 136,000 people from around the world found that those individuals whose diets most closely resembled a Mediterranean diet were 23% less likely to develop type 2 diabetes. A Mediterranean Diet includes beans, fruits, vegetables, fish, whole grains, herbs, spices, nuts and olive oil.
  4. Eat quality. This has really been said a few times already, but it deserves its own bullet. Choose whole-wheat toast over toaster pastries; chocolate-covered almonds over chocolate brownies; liquid oil over coconut oil or butter; baked fish over a fast food fish sandwich; a bowl of oats over a bowl of sugary cereal; an orange over orange sherbet; and bean and lentils a few times a week over a daily plate of beef, pork or poultry.

    • The American Diabetes Association finds that higher intakes of nuts, berries, yogurt, coffee and tea are associated with less risk of developing type 2 diabetes. Check out what else to add to your prediabetes shopping list.
  5. Eat the right amount. Typically insulin resistance and blood sugar improve when we cut calories. If you don’t need to lose weight – and many people with diabetes and prediabetes don’t – eat the amount of food and calories needed to maintain a healthy weight. But if you carry extra pounds, trimming calories even a bit can make a significant improvement.

Healthy Eating for Prediabetes: Meal Ideas

(aka creating your best prediabetes diet)

With the guidelines above, you can create an infinite number of healthy meals for your prediabetes diet. To get you started, here’s a day’s wortPrediabetes: A Complete Guideh of meals heavy on those foods that science says are good for type 2 diabetes prevention.

Be sure to take a look at Prediabetes: A Complete Guide. It’s definitely complete with chapters on diet, activity, sleep, mindset, goal setting, developing habits, grocery shopping, eating in restaurants and more.

Breakfast: Yogurt with berries, walnuts and muesli; coffee or tea

  • Here you’ve got 5 prediabetes foods: coffee or tea, yogurt, berries, walnuts and oats in the muesliIf you haven’t had muesli before, it’s worth a try. It’s a lot like granola, but it’s uncooked and without the oil. I love it!

Lunch: Lentil soup, leafy greens with orange segments, a few whole-grain crackers, low-fat cottage cheese (for additional protein)

  • The prediabetes foods are the lentils, oranges (because they have viscous fibers) and vegetables, of course.

Dinner: Baked salmon, mushroom-barley pilaf, roasted broccoli, 5 or 6 chocolate-covered almonds for dessert

  • Barley is a prediabetes food because of the fiber called beta-glucan. Your dessert (which happens to be my usual dessert) gives you diabetes-fighting nuts. The salmon and broccoli are also health boosters.

Snacks: Snacks should fill in nutritional gaps, and you should eat them according to your hunger. You do not need snacks for weight loss or for prediabetes management.

  • yogurt
  • nuts
  • roasted chickpeas
  • edamame beans
  • hummus and veggies
  • celery and peanut butter
  • fruit

All of the above are prediabetes foods. See this list of snacks for other ideas.

    As a pre-diabetic, may I have beer? What about other forms of alcohol – realizing all drinking should be done to a minimum (not more than one drink per day for a woman or two for a man).

    • Jill Weisenberger on July 3, 2019 at 2:46 pm

      Great question! Also great that you know the definition of moderate drinking – up to one drink daily for women and no more than 2 daily for men. Yes, people with prediabetes can have alcohol. This is from page 63 in my newest book Prediabetes: A Complete Guide. “Consuming small amounts of alcohol is linked to less type 2 diabetes. But alcohol in excess is linked to more, as well as many other health problems. That’s why the American Diabetes Association and other organizations do not recommend drinking for the prevention of disease. If you do drink, you don’t need much. The benefits of drinking alcohol appear to occur with as little as 1/2 standard drink daily.” So prediabetes is not a reason to avoid alcohol.

      Thanks for reaching out. While I think my book, Prediabetes: A Complete Guide is a terrific book for beginners and those more advanced, I think you will benefit most from working one-on-one with a skilled registered dietitian nutritionist (RDN). Find one local to you at eatright.org. You can use the book as additional info, but if you need highly personalized advice,ask your doctor for a referral to an RDN. Keep us posted on your progress!

    I love that you touched on eating quality ingredients as much as you can so that you stay healthier. My dad is diabetic and needs to switch up his diet.

  5. Viggo Crowe on August 7, 2020 at 10:20 am

    It’s really interesting that you touched on how pre-diabetes can actually lead to other big issues, such as cancer. My brother is having some health issues based on his weight and diet. He needs to find a local nutritionist that can create a good plan that he can follow.
