Nutrition Tips for Prediabetes: What to Eat and Avoid

Prediabetes is a critical health condition that affects millions of people worldwide, serving as a warning sign that blood sugar levels are elevated but not yet high enough to be classified as type 2 diabetes. People with prediabetes have fasting blood sugar levels that are elevated, but not to the point that they meet the criteria of type 2 diabetes. The good news is that prediabetes is not a life sentence. Prediabetes can be erased through healthy lifestyle changes — including eating more nutritious foods — which can reverse the diagnosis and bring blood sugar levels back into line. Understanding what to eat and what to avoid is fundamental to managing this condition and preventing its progression to full-blown diabetes.

Understanding Prediabetes and the Role of Nutrition

When you have prediabetes, your body’s ability to process glucose effectively becomes impaired. This means that the foods you consume have a direct and significant impact on your blood sugar levels. The key to warding off progression of prediabetes is a balanced approach to diet. Rather than following restrictive fad diets or eliminating entire food groups, the focus should be on making gradual, sustainable changes to your eating habits.

Individualized medical nutrition therapy should be provided by referring people with prediabetes to a registered dietitian nutritionist, preferably one who has comprehensive experience in diabetes care. This personalized approach ensures that your dietary plan takes into account your unique health status, preferences, and metabolic goals. The investment in proper nutrition guidance can yield significant returns, as diabetes medical nutrition therapy can result in cost savings and improved cardiometabolic outcomes.

Research has consistently demonstrated the power of dietary interventions in managing prediabetes. Incorporating healthy eating habits, weight reduction and increased physical activity can lower your risk of developing type 2 diabetes, with lifestyle changes resulting in modest weight loss showing to delay the onset of type 2 diabetes by 34% for four years compared to placebo. This evidence underscores the critical importance of taking action as soon as you receive a prediabetes diagnosis.

The Glycemic Index: Your Guide to Blood Sugar Management

One of the most valuable tools for managing prediabetes is understanding the glycemic index (GI). The glycemic index measures how much a food boosts blood sugar, rating the effect of a specific amount of a food on blood sugar compared with the same amount of pure glucose. Foods are ranked on a scale from 0 to 100, with pure glucose serving as the reference point at 100.

How the Glycemic Index Works

The glycemic index categorizes foods into three main groups:

Low GI (55 or less): Most fruits and vegetables, beans, minimally processed grains, pasta, low-fat dairy foods, and nuts.
Medium GI (56-69): Foods that include potatoes, white rice, corn, couscous, and breakfast cereals such as Mini-Wheats and Cream of Wheat.
High GI (70 or more): White bread, cakes, doughnuts, cookies, rice cakes, most crackers, bagels, croissants, and most packaged breakfast cereals.

Your blood sugar does not spike as much, and the response demands less insulin, when you choose low-GI foods, which is especially good news if you have prediabetes or diabetes. By focusing on low-GI foods, you can help maintain more stable blood sugar levels throughout the day, reducing the strain on your body’s insulin response system.

Factors That Affect Glycemic Index

Understanding what influences a food’s GI can help you make better choices even when you don’t have access to specific GI values. Several factors determine how quickly a food raises blood sugar:

Fiber content affects GI, as more fiber equals slower digestion; processing and refinement matter, with more processing equaling higher GI; ripeness plays a role, as riper fruit usually has a higher GI; and cooking method is important, as longer cooking often increases GI. These principles can guide your food preparation and selection strategies.

For example, whole grains are often lower-GI than refined, whole fruit is lower-GI than fruit juice, and raw carrots are lower-GI than cooked. This knowledge empowers you to make simple modifications to your meals that can have a significant impact on your blood sugar response.

Foods to Include in Your Prediabetes Diet

Building a prediabetes-friendly diet doesn’t mean deprivation. Instead, it’s about emphasizing nutrient-dense foods that support stable blood sugar levels while providing essential vitamins, minerals, and other beneficial compounds. For diabetes prevention and management of people with prediabetes, individualized meal plans should keep nutrient quality, total calories, and metabolic goals in mind, with eating patterns emphasizing key nutrition principles including nonstarchy vegetables, whole fruits, legumes, lean proteins, whole grains, nuts and seeds, and low-fat dairy or nondairy alternatives.

Non-Starchy Vegetables: The Foundation of Your Plate

Nutrition choices should emphasize non-starchy vegetables such as spinach, salad greens, cauliflower, broccoli, Brussels sprouts, asparagus, tomatoes, celery, and zucchini. These vegetables are nutritional powerhouses that provide fiber, vitamins, minerals, and antioxidants while having minimal impact on blood sugar levels.

The American Diabetes Association recommends a simple plate method for meal planning: Start with a nine-inch plate and fill half with non-starchy veggies, one-quarter with lean proteins, and one-quarter with quality carbs like starchy vegetables, fruits, whole grains, or low-fat dairy. This visual approach makes it easy to create balanced meals without complicated calculations or measurements.

Non-starchy vegetables you should incorporate regularly include:

Leafy greens such as spinach, kale, collard greens, and Swiss chard
Cruciferous vegetables like broccoli, cauliflower, Brussels sprouts, and cabbage
Colorful peppers (bell peppers, jalapeños)
Tomatoes and cucumbers
Zucchini and summer squash
Asparagus and green beans
Mushrooms and eggplant
Celery and radishes
Onions and garlic

Whole Grains: Choose Wisely

Not all carbohydrates are created equal. Whole grains retain their fiber-rich outer layer and nutrient-dense germ, making them a much better choice than refined grains for blood sugar management. Try cereals with at least five grams of fiber per serving, whole fruits, vegetables and whole grains.

Excellent whole grain choices include:

Steel-cut or rolled oats (not instant)
Brown rice, wild rice, and black rice
Quinoa (technically a seed but used like a grain)
Barley and bulgur
Whole wheat pasta (cooked al dente)
Farro and freekeh
Buckwheat and millet
100% whole grain bread (check labels carefully)

Limiting portion sizes of refined carbohydrate foods such as white bread, white rice and white pasta while incorporating fiber to reach a goal of 25 to 30 grams per day by eating a variety of fruits, vegetables and whole grains is a key strategy for managing prediabetes effectively.

Lean Proteins: Building Blocks for Stable Blood Sugar

Protein plays a crucial role in blood sugar management by slowing down the digestion and absorption of carbohydrates. Balanced meals should incorporate lean protein, low fat dairy and plenty of fiber. Including adequate protein at each meal helps prevent blood sugar spikes and keeps you feeling satisfied longer.

Excellent lean protein sources include:

Skinless chicken and turkey breast
Fish and seafood (especially fatty fish like salmon, mackerel, and sardines)
Eggs and egg whites
Greek yogurt (unsweetened)
Cottage cheese (low-fat)
Legumes such as lentils, chickpeas, and black beans
Tofu and tempeh
Lean cuts of beef and pork (in moderation)

Cooking chicken or turkey with the skin on will preserve moisture and have little effect on the fat content, but it’s important to remove the skin before eating. This simple technique allows you to enjoy moist, flavorful poultry while keeping the fat content low.

Healthy Fats: Essential for Metabolic Health

Eating a diet low in saturated fat and trans fat can help reduce your risk of developing heart disease. However, not all fats are harmful. In fact, healthy fats are essential for nutrient absorption, hormone production, and satiety.

Focus on incorporating these healthy fat sources:

Avocados and avocado oil
Nuts such as almonds, walnuts, pecans, and cashews
Seeds including chia seeds, flaxseeds, hemp seeds, and pumpkin seeds
Extra virgin olive oil
Fatty fish rich in omega-3 fatty acids
Natural nut butters (without added sugar)
Olives

These foods provide monounsaturated and polyunsaturated fats that support heart health and help with the absorption of fat-soluble vitamins. Large epidemiologic studies have found that consumption of polyunsaturated fat or biomarkers of polyunsaturated fatty acids are associated with lower risk of type 2 diabetes.

Fruits: Nature’s Sweet Treat

Many people with prediabetes worry about eating fruit due to its natural sugar content. However, all types of fruit are OK and unlikely to be a problem for people who have prediabetes (with the exception of pomegranate juice and grapefruit for people taking certain medications). The key is choosing whole fruits over fruit juices and being mindful of portions.

Fiber slows down the digestion of sugars, which prevents spikes in blood sugar, so since fruit’s natural sugar is accompanied by fiber, it doesn’t cause much of a blood sugar spike. This makes whole fruit a much better choice than fruit juice, which lacks fiber and can cause rapid blood sugar increases.

Best fruit choices for prediabetes include:

Berries (strawberries, blueberries, raspberries, blackberries)
Apples and pears (with skin)
Citrus fruits (oranges, grapefruits, tangerines)
Cherries
Peaches and plums
Kiwi
Apricots

Fruits with an edible peel — like apples, pears, and berries — have the most fiber. Aim to eat these fruits with their skins intact whenever possible to maximize fiber intake and slow sugar absorption.

Legumes and Beans: Fiber-Rich Powerhouses

Raw green vegetables, most citrus fruits, raw carrots, kidney beans, chickpeas, lentils, and bran breakfast cereals are low glycemic foods. Legumes deserve special attention in a prediabetes diet because they provide an excellent combination of protein, fiber, and complex carbohydrates.

Include these legumes regularly:

Lentils (red, green, brown, black)
Chickpeas (garbanzo beans)
Black beans
Kidney beans
Navy beans
Pinto beans
Split peas
Edamame (young soybeans)

Legumes can be added to salads, soups, stews, and grain dishes. They’re also excellent as the base for dips like hummus or as a partial replacement for meat in various recipes.

Foods to Limit or Avoid with Prediabetes

While no food needs to be completely off-limits forever, certain foods can make blood sugar management significantly more challenging. Rethinking your diet to address prediabetes doesn’t have to mean giving up foods you love, but it may mean eating them less often and in smaller amounts while adding in more nutritious alternatives.

Added Sugars and Sweetened Foods

Sugar is a quick-release carb, so your body quickly releases glucose into your bloodstream when you eat it, which causes a spike in your blood sugar level. This rapid spike is exactly what you want to avoid when managing prediabetes.

The American Heart Association recommends less than six teaspoons of sugar a day for women (about 25 grams) and less than nine teaspoons (about 36 grams) a day for men for people at risk for heart disease, including those with prediabetes. To put this in perspective, one can of soda contains about 32 grams of sugar, which is about eight teaspoons.

Foods high in added sugars to limit or avoid include:

Regular soda and sweetened beverages
Candy and chocolate bars
Cookies, cakes, and pastries
Ice cream and frozen desserts
Sweetened breakfast cereals
Flavored yogurts with added sugar
Sweetened coffee drinks and specialty beverages
Energy drinks and sports drinks
Sweetened tea and lemonade

Refined Carbohydrates and Processed Grains

Refined carbohydrates have been stripped of their fiber and nutrients, leaving behind quickly digested starches that can cause rapid blood sugar spikes. These foods should be minimized in a prediabetes diet.

Refined carbohydrates to limit include:

White bread and white sandwich rolls
White rice
Regular pasta made from refined flour
White flour tortillas
Crackers made with refined flour
Pretzels and breadsticks
Most bagels and English muffins
Pancakes and waffles made with white flour

Sugar-Sweetened Beverages: A Major Culprit

Beverages deserve special attention because they’re one of the largest sources of added sugar in the modern diet. Sweetened beverages such as sodas, sports drinks, juices and gourmet coffee shop creations account for some of the biggest concentrated sources of added sugar.

Research shows the significant impact of sweetened beverages on diabetes risk. Consumption of at least one serving of sugar-sweetened beverages per day increased risk of type 2 diabetes in adults with prediabetes by 26%. Conversely, the replacement of sugar-sweetened beverages with an equal amount of water reduced the risk of type 2 diabetes by 7–8%.

If you have prediabetes, it’s a good idea to limit or skip 100% fruit juice, soda, and sweetened coffee drinks, and try to avoid energy or sports drinks, mixed alcohol cocktails, and lemonade or sweet tea. Instead, focus on water, unsweetened tea, coffee without added sugar, and sparkling water with a splash of fresh fruit for flavor.

The 2025 Standards of Care emphasizes water intake over nutritive and nonnutritive sweetened beverages; and the use of nonnutritive sweeteners over sugar-sweetened products in moderation and for the short term to reduce overall calorie and carbohydrate intake.

Processed and Fried Foods

Highly processed foods often contain a combination of refined carbohydrates, unhealthy fats, and added sugars—a trifecta that can wreak havoc on blood sugar levels. Additionally, these foods tend to be low in fiber and nutrients while being high in calories.

Processed and fried foods to minimize:

Fast food burgers and fried chicken
French fries and onion rings
Fried fish and seafood
Potato chips and corn chips
Processed meats like hot dogs, sausages, and deli meats high in sodium
Frozen meals high in sodium and refined carbs
Packaged snack cakes and pastries
Microwave popcorn with added butter and salt

Alcohol: Moderation is Key

Moderation is a healthy rule to live by in most instances, and drinking alcohol is no exception, as many alcoholic beverages are dehydrating and some cocktails may contain high amounts of sugar, which can cause blood sugar spikes.

If you choose to drink alcohol, do so in moderation and be aware of how different beverages affect your blood sugar. Sweet cocktails, liqueurs, and dessert wines are particularly problematic due to their high sugar content. Beer and wine in moderate amounts may be acceptable for some people, but always consult with your healthcare provider about what’s appropriate for your situation.

Evidence-Based Eating Patterns for Prediabetes

Rather than following a one-size-fits-all approach, research supports several different eating patterns that can be effective for managing prediabetes. There is no “one-size-fits-all” answer to diet and diabetes. The key is finding an approach that you can sustain long-term while meeting your health goals.

Mediterranean Diet

The Mediterranean diet is regarded as the gold standard for people with prediabetes, with its emphasis on whole grains, lean protein and healthy fats. This eating pattern has been extensively studied and shows impressive results for diabetes prevention.

The PREDIMED trial, a large randomized controlled trial, compared a Mediterranean-style to a low-fat eating pattern for prevention of type 2 diabetes onset, with the Mediterranean-style eating pattern resulting in a 30% lower relative risk. This significant reduction in diabetes risk makes the Mediterranean diet one of the most evidence-based approaches for prediabetes management.

The Mediterranean diet emphasizes:

Abundant vegetables and fruits
Whole grains and legumes
Olive oil as the primary fat source
Fish and seafood several times per week
Moderate amounts of poultry, eggs, and dairy
Limited red meat
Herbs and spices for flavoring instead of salt
Moderate wine consumption with meals (optional)

Low-Carbohydrate Approaches

Reducing overall carbohydrate intake for people with diabetes has “the most evidence” for improving blood sugars. Recent years have seen increased recognition of low-carbohydrate diets as a viable option for managing prediabetes and type 2 diabetes.

The latest research shows that some people with type 2 diabetes can even put their diabetes into remission with enough weight loss or by following low-carbohydrate diets. While prediabetes is different from diabetes, these findings suggest that carbohydrate reduction can be a powerful tool for improving blood sugar control.

A low-carbohydrate approach typically involves:

Emphasizing non-starchy vegetables
Including adequate protein at each meal
Incorporating healthy fats
Limiting grains, starchy vegetables, and fruits to smaller portions
Avoiding added sugars and refined carbohydrates
Focusing on whole, minimally processed foods

DASH Diet

A Mediterranean or plant-based (vegetarian or vegan) diet may help, and the DASH (dietary approaches to stop hypertension) diet is also an option. The DASH diet was originally designed to lower blood pressure, but it also shows benefits for blood sugar management.

The DASH diet emphasizes:

Vegetables and fruits
Whole grains
Low-fat or fat-free dairy products
Lean meats, poultry, and fish
Nuts, seeds, and legumes
Limited sodium, sweets, and red meat

Plant-Based Diets

Vegetarian and vegan diets have also shown promise for prediabetes management. These eating patterns naturally emphasize whole plant foods that are rich in fiber and nutrients while being lower in saturated fat.

A plant-based approach for prediabetes includes:

Abundant vegetables of all types
Whole fruits
Whole grains and pseudo-grains
Legumes and soy products
Nuts and seeds
Plant-based oils
Limited or no animal products

Practical Strategies for Blood Sugar Management

Beyond choosing the right foods, how you eat and structure your meals can significantly impact blood sugar control. These practical strategies can help you optimize your dietary approach to prediabetes management.

Portion Control and Meal Timing

Paying attention to portion sizes can help you keep your diet low on the glycemic index scale, as often, portion sizes in the United States are much larger than intended serving sizes. Even healthy foods can cause blood sugar problems if consumed in excessive amounts.

Food labels can help you determine how much you’re actually eating, as the label will list calories, fat, carbohydrates, and other nutritional information for a particular serving, and if you eat more than the serving listed, it’s important to understand how that will affect the nutritional value.

Eating smaller, more frequent meals throughout the day can help prevent large blood sugar fluctuations. Rather than eating three large meals, consider eating five to six smaller meals or three moderate meals with healthy snacks in between. This approach helps maintain more stable blood sugar levels and can prevent the extreme hunger that often leads to overeating.

Combining Foods Strategically

Eating mixed meals is a great way to lower a food’s glycemic index; for example, if you plan to eat white rice, adding vegetables and chicken cooked in a small amount of healthy fat can slow down the digestion of the grain and minimize blood sugar spikes.

The principle of food combining for blood sugar management involves:

Never eating carbohydrates alone—always pair them with protein and/or healthy fat
Starting meals with vegetables or protein rather than carbohydrates
Including fiber-rich foods at every meal
Adding a source of healthy fat to help slow digestion
Balancing your plate according to the diabetes plate method

It’s best to pair fruit with protein to prevent blood-sugar spikes. For example, instead of eating an apple alone, pair it with a tablespoon of almond butter. Instead of having berries by themselves, add them to Greek yogurt.

Fiber: Your Blood Sugar’s Best Friend

Fiber deserves special attention in prediabetes management because of its powerful effects on blood sugar control. Fiber may reduce fasting blood sugar in people with prediabetes and diabetes, and may also reduce hemoglobin A1C, a marker of longer-term blood sugar control.

Aim for 25 to 30 grams of fiber per day from a variety of sources:

Vegetables (especially leafy greens and cruciferous vegetables)
Whole fruits with skin
Legumes and beans
Whole grains
Nuts and seeds
Chia seeds and flaxseeds

Increase fiber gradually to avoid digestive discomfort, and make sure to drink plenty of water as you increase your fiber intake.

Meal Planning and Preparation

Success with prediabetes management often comes down to planning and preparation. When you have healthy meals and snacks readily available, you’re less likely to make impulsive food choices that could negatively impact your blood sugar.

Effective meal planning strategies include:

Planning your meals for the week ahead
Creating a shopping list based on your meal plan
Batch cooking proteins and whole grains on weekends
Preparing vegetables in advance (washing, chopping, storing)
Keeping healthy snacks portioned and ready to grab
Using meal prep containers to portion out balanced meals
Keeping a well-stocked pantry with prediabetes-friendly staples

Reading Food Labels

Understanding food labels is crucial for making informed choices. Pay particular attention to:

Serving size: This is the foundation for all other numbers on the label
Total carbohydrates: This includes sugars, starches, and fiber
Dietary fiber: Higher fiber content is better for blood sugar control
Added sugars: Look for products with minimal or no added sugars
Ingredient list: Ingredients are listed in order by weight; avoid products where sugar appears in the first few ingredients

Be aware that sugar can hide under many names on ingredient lists, including high fructose corn syrup, cane sugar, agave nectar, honey, molasses, dextrose, maltose, and many others.

The Role of Weight Loss in Prediabetes Management

Weight loss, even modest amounts, can have a profound impact on prediabetes. Even small amounts of weight loss can have a benefit, as moderate rate reduction of 5% to 10% of your body weight can significantly lower your A1C level—for instance, for a person weighing 200 pounds, a weight loss of 10 to 20 pounds could make a difference.

An overweight or obesity treatment plan based on nutrition, physical activity, and behavioral health status should be provided for all people with overweight or obesity, aiming for at least 5–7% weight loss. This recommendation is based on substantial evidence showing that weight loss improves insulin sensitivity and can even reverse prediabetes in many cases.

Research on diabetes remission provides encouraging evidence for the power of weight loss. The DiRECT trial showed that at 1 year, weight loss associated with lifestyle intervention resulted in diabetes remission in 46% of participants, with remission rates related to magnitude of weight loss, rising progressively from 7% to 86% as weight loss at 1 year increased from less than 5% to 15% or more. While this study focused on type 2 diabetes rather than prediabetes, it demonstrates the powerful metabolic effects of weight loss.

Strategies for sustainable weight loss include:

Creating a moderate calorie deficit through diet and exercise
Focusing on nutrient-dense, filling foods
Eating adequate protein to preserve muscle mass
Incorporating regular physical activity
Getting adequate sleep (7-8 hours per night)
Managing stress through healthy coping mechanisms
Tracking your food intake and progress
Working with healthcare professionals for support and accountability

Lifestyle Factors Beyond Diet

While nutrition is crucial for managing prediabetes, it’s not the only factor that matters. A comprehensive approach to prediabetes management includes several lifestyle components that work synergistically with dietary changes.

Physical Activity

Lifestyle changes resulting in modest weight loss have shown to delay the onset of type 2 diabetes by 34% for four years compared to placebo, and people with prediabetes should try to get at least 150 minutes per week of moderate to vigorous exercise or aim for 10,000 daily steps.

Physical activity helps manage prediabetes by:

Improving insulin sensitivity
Helping with weight management
Lowering blood sugar levels
Reducing cardiovascular disease risk
Improving mood and reducing stress
Building and maintaining muscle mass

The 2025 Standards of Care emphasizes the importance of meeting resistance training guidelines for those treated with weight management pharmacotherapy or metabolic surgery. Resistance training is particularly important because muscle tissue is highly insulin-sensitive and helps regulate blood sugar.

Sleep Quality

Sleep deprivation has been shown to increase people’s cravings for sugary foods, and people with prediabetes should make sure they’re getting seven to eight hours of sleep a night. Poor sleep can also directly impair insulin sensitivity and glucose metabolism, making blood sugar management more difficult.

Strategies for improving sleep include:

Maintaining a consistent sleep schedule
Creating a relaxing bedtime routine
Keeping your bedroom cool, dark, and quiet
Limiting screen time before bed
Avoiding caffeine in the afternoon and evening
Getting regular physical activity (but not too close to bedtime)
Managing stress through relaxation techniques

Stress Management

Chronic stress can elevate cortisol levels, which can increase blood sugar and promote insulin resistance. Additionally, stress often leads to emotional eating and poor food choices, further complicating blood sugar management.

Effective stress management techniques include:

Mindfulness meditation
Deep breathing exercises
Yoga or tai chi
Regular physical activity
Spending time in nature
Engaging in hobbies and activities you enjoy
Maintaining social connections
Seeking professional support when needed

Hydration

Staying well-hydrated is important for overall health and can support blood sugar management. Water helps your kidneys flush out excess blood sugar through urine and supports all metabolic processes in your body.

Aim for at least 8 glasses of water per day, and more if you’re physically active or in hot weather. Choose water as your primary beverage, and limit or avoid sugary drinks, as discussed earlier.

Special Considerations and Cautions

Medication Interactions

Some foods and supplements can interact with medications. Grapefruit and pomegranate juice can interact with some medications, since they are processed by the same liver enzyme that metabolizes medication. If you’re taking any medications, discuss potential food-drug interactions with your healthcare provider or pharmacist.

Ginseng, gingko and garlic are OK in moderation, but high doses of these, as you get in over-the-counter supplements, can cause low blood sugar, so it is always important to know your risks and follow the proper dietary protocol by consulting your doctor or dietitian.

Individual Variability

Because everyone is different and many people with prediabetes have other health issues, it is important to tailor prediabetes food plans to the individual—for instance, patients with high cholesterol may do better with a lower-fat approach, while those with high A1C may benefit from a meal plan that’s lower in carbohydrates.

This underscores the importance of working with healthcare professionals, particularly registered dietitians who specialize in diabetes care, to develop a personalized nutrition plan that addresses your specific needs, preferences, and health conditions.

Avoiding Fad Diets

People with prediabetes do not have to eliminate entire food groups, as all foods can fit in the meal plan, and patients should steer clear of fad diets and other strategies that promise quick fixes, since their claims are not supported, and gradual behavior changes should be encouraged.

Sustainable lifestyle changes are far more effective than extreme diets that are difficult to maintain long-term. Focus on making gradual improvements to your eating habits rather than pursuing dramatic overhauls that you can’t sustain.

Managing prediabetes doesn’t mean you can never eat out or enjoy social occasions. With some planning and smart choices, you can navigate restaurants and social events while staying on track with your health goals.

Restaurant Strategies

When eating out:

Review the menu online before you go to plan your choices
Ask for dressings and sauces on the side
Request substitutions (vegetables instead of fries, for example)
Choose grilled, baked, or steamed preparations over fried
Start with a salad or vegetable-based soup
Share entrees or ask for a to-go box at the beginning of the meal
Skip the bread basket or ask the server not to bring it
Choose water, unsweetened tea, or other sugar-free beverages

Special occasions can be challenging, but they don’t have to derail your progress:

Eat a small, balanced meal before attending events so you’re not overly hungry
Focus on socializing rather than eating
Fill your plate with vegetables and lean proteins first
Practice portion control with higher-carb or sweet foods
Limit alcohol consumption
Don’t skip meals earlier in the day to “save up” for the event
Bring a healthy dish to share at potlucks
Remember that one meal or one day won’t undo your overall progress

Monitoring Your Progress

Tracking your progress is essential for understanding what works for your body and staying motivated. Regular monitoring helps you identify patterns and make informed adjustments to your approach.

Blood Sugar Testing

While not everyone with prediabetes needs to test their blood sugar at home, some people find it helpful to understand how different foods affect their glucose levels. If your healthcare provider recommends home monitoring, you might test:

Fasting blood sugar (first thing in the morning)
Post-meal blood sugar (1-2 hours after eating)
Before and after exercise

Keep a log of your readings along with notes about what you ate, your activity level, stress, sleep, and other factors that might influence your blood sugar.

Regular Medical Follow-Up

Schedule regular appointments with your healthcare provider to monitor your progress through:

Hemoglobin A1C tests (typically every 3-6 months)
Fasting blood glucose tests
Lipid panels
Blood pressure checks
Weight and body composition measurements

These objective measures help you and your healthcare team assess whether your dietary and lifestyle changes are effectively managing your prediabetes.

Food and Symptom Journaling

Keeping a food journal can provide valuable insights into your eating patterns and how different foods affect you. Record:

What you eat and drink
Portion sizes
Time of day
Hunger and fullness levels
Energy levels
Mood
Physical symptoms
Physical activity

Review your journal regularly to identify patterns and areas for improvement.

Building a Support System

Managing prediabetes is easier when you have support from others. Consider:

Healthcare team: Work with your doctor, registered dietitian, diabetes educator, and other healthcare professionals
Family and friends: Share your goals with loved ones and ask for their support
Support groups: Join in-person or online communities of people managing prediabetes
Accountability partner: Find someone with similar health goals to check in with regularly
Educational resources: Take advantage of diabetes prevention programs and educational materials

Patients can be referred to diabetes meal planning recommendations from the Centers for Disease Control and Prevention and a version of the MyPlate guidelines issued by the U.S. Department of Agriculture and adapted by the American Diabetes Association, as though these resources are not specifically for prediabetes, they can serve as a guide to incorporating healthy choices, especially when eating away from home.
