10 Golden Rules for Eating With Prediabetes

More than 40 percent of adults in the United States have prediabetes, which occurs when your blood sugar level exceeds a healthy range but is not yet at the level of type 2 diabetes. Lifestyle changes such as exercise and adjusting your diet can help you manage your weight and blood sugar to reduce your type 2 diabetes risk.
“Maintaining a healthy weight is important for everyone,” says Kimberly Rose-Francis, RDN, CDCES, who is based in Florida. “Losing weight can help reduce insulin resistance and may even delay or prevent complications from arising.”
In addition to physical activity, adjusting your eating habits is key to preventing the onset of type 2 diabetes. Following a few simple tips while heeding the advice of your doctor and healthcare team can help you manage your condition while avoiding complications.

Does Prediabetes Always Lead to Diabetes?
1. Skip Sugary Drinks
“My first recommendation to people is don’t drink your sugar,” says Barbara Borcik, RD, CDCES, of Reisterstown, Maryland. “All the sugary drinks out there are a real risk factor for obesity.”
2. Pull Back on Portions
3. Fill Up on Fiber
In particular, vegetables are diabetes-friendly because they tend to be high in fiber and low in calories and carbohydrates, says Joelle Malinowski, RD, CDCES, who is based in Albany, New York. She suggests sautéing them in light oil or steaming or baking them.
And don’t overthink the type of veggie you’re buying. “Fresh, frozen, and canned veggies are all nutritious options for people with prediabetes,” says Lori Zanini, RD, CDCES, who is based in Dana Point, California.
4. Be Choosy About Fats
“Fats that come from avocados, nuts, oily fish, and other plant oils have a heart health benefit,” Rose-Francis says.
5. Emphasize Whole Grains
“Refined grains are processed to remove the fiber,” Rose-Francis says. “In people with diabetes, fiber can improve blood sugar levels, promote increased satiety, and consequently control weight.”
6. Choose Meat Alternatives
“The plant-based diet isn’t for everyone,” Malinowski says. “But think about swaps like choosing olive oil over butter.”
7. Drink Alcohol Only in Moderation
If you’re trying to lose weight or be as healthy as possible, consider limiting your alcohol intake or ditching it altogether.
“Alcohol is a very calorie-dense beverage, which means it can supply a lot of calories, cause unwanted weight gain, and supply few nutrients for the body,” Rose-Francis says.
While research on alcohol is evolving, the World Health Organization says that drinking less or not at all is better for your health.
Malinowski suggests limiting alcohol to once a week or abstaining completely if weight loss is your goal. “It’s better to lose it if you want faster results,” she says. “Plus, alcohol sometimes increases appetite.”
8. Pick Healthy Proteins
- Salmon
- Nuts
- Oats
- Turkey breast
- Egg whites and whole eggs
- Soy milk
- Skinless and boneless chicken breast
- Tofu
9. Choose Lean Meats
Also consider baking, broiling, roasting, grilling, or sautéing rather than frying your food, Borcik says.
10. Stay Hydrated
People can sometimes mistake thirst for hunger, which can lead to overeating and weight gain, Zanini says. So drink plenty of water.
“It will help your body function more optimally, give you more energy, and has been shown to aid in weight management,” she says.
