Having prediabetes is a risk factor for developing type 2 diabetes within a few years, but making changes in the way you eat can lower your risk, according to the Centers for Disease Control and Prevention. Along with losing 5 to 7% of body weight if you are overweight or obese, choosing more nutritious foods can slow or reverse insulin resistance and lower blood sugar.
Best Diets for Prediabetes
Many different eating patterns can help lower blood sugar and reduce the chance of developing diabetes, according to the American Diabetes Association. These are some dietary patterns that have been linked to weight loss, lower blood sugar, and/or lower risk for diabetes.
Vegetarian or vegan
DASH (Dietary Approaches to Stop Hypertension)
For most people, the most important consideration is whether the diet is sustainable for them. Someone who loves meat may not be able to follow a meatless diet indefinitely, and may go back to old eating habits soon. Similarly, someone who loves pasta and bread may feel deprived on a low-carbohydrate diet and may not be able to stick to the plan.
Following are sample menus for each of the above types of diet to lower blood sugar and decrease risk for diabetes.
Vegetarian diets include strict vegan diets, which do not include any animal-source foods, as well as ovo-lacto vegetarian diets, which include eggs and cheese but no fish or meat. Pesco-vegetarian diets include fish.
Each of these patterns has been linked to weight loss, lower risk for type 2 diabetes, and reduced A1C (or glycated hemoglobin, a measure of long-term blood sugar control. According to research published in Current Diabetes Reports, compared to regular meat-eaters who had a prevalence of diabetes of 7.9%, vegan diet eaters had a 2..9% prevalence, those who ate an lacto-ovo vegetarian diet had a 3.2% prevalence, and those who followed a pesco-vegetarian diet had a 4.8% prevalence of diabetes. Patterns were similar for body mass index (BMI), a measure of a healthy body weight.
Sample Menu for a Vegetarian Diet
Plain oatmeal made with milk or almond milk and fruit
Whole-grain pita with hummus, sprouts, and grilled vegetables or lettuce, served with fruit
Vegetarian chili with onions, tomatoes, bell peppers, celery, your choice of beans, and spices, served with (optional) lettuce, yogurt, a whole-grain dinner roll, and/or cheese
Tofu or eggs cooked with sweet potatoes, bell peppers, and onions
Veggie or bean burger on a whole-grain bun (or bread) with lettuce and tomato, plus baby carrots, and fruit on the side
Bean (and optional cheese) burrito with steamed vegetables

Mediterranean Diet Patterns
You are correct if you think, "heart health," "red wine," and "olive oil," when you think of Mediterranean diets, but wait, there is more! What about, "weight loss," "lower A1C," and, "whole grains," as the American Diabetes Association points out? The Dietary Guidelines also suggest a Mediterranean diet as one of many possible healthy eating patterns to try.
It emphasizes vegetables, fruits, and healthy fats such as olive oil, as well as whole grains and protein sources such as fish and beans. To limit are sugars and unhealthy fats, as well as red meat.
Cottage cheese with oats and cantaloupe
Quinoa and lentil salad with tomatoes, feta, cucumber, onion, and olive oil
Chicken stir fry with vegetables, using olive oil, and served with brown rice
Shredded wheat with berries and milk
Whole-wheat pita with chicken breast, hummus, and raw vegetables
Baked salmon with sweet potato fries baked with olive oil and steamed broccoli
Low-Carbohydrate Diet Patterns
Carbohydrates drive up blood sugar levels, and cutting back on carbohydrates may help lower blood sugar in diabetes and prediabetes. The American Diabetes Association says a low-carb diet may get below about 40 to 45% of calories from carbohydrates, with the other calories coming from fat and protein.
Eggs, fish, poultry, and meat are carbohydrate-free foods, and they may be the foundation of a low-carb diet, along with non-starchy vegetables. Fats are also carbohydrate-free or low-carb, and healthy ones include olive oil, canola oil, nuts, seeds, and avocados. Low-carb diets may limit fruits, grains, and sugar-sweetened foods and beverages.
