Understanding Prediabetes and the Power of Nutrition
Prediabetes is a health warning stage where blood sugar is higher than it should be but not high enough to be classified as Type 2 diabetes. It’s estimated that 38% of American adults have prediabetes, making it a widespread health concern that demands attention. The good news? 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.
Managing prediabetes involves making informed dietary choices to help control blood sugar levels and prevent progression to type 2 diabetes. Small daily adjustments can significantly impact your health and quality of life. This comprehensive guide provides practical, evidence-based nutrition tips to support a healthy lifestyle for those with prediabetes, drawing from the American Diabetes Association’s Standards of Care in Diabetes—2025, the gold standard in evidence-based guidelines for diagnosing and managing diabetes and prediabetes.
The Science Behind Blood Sugar Control
Blood sugar control is complex, involving many body processes. The body keeps blood glucose levels stable by balancing insulin and glucagon. Insulin helps cells take in glucose, while glucagon releases glucose into the blood. In prediabetes, insulin resistance disrupts this balance, causing high blood glucose.
Understanding how different foods affect your blood sugar is crucial for managing prediabetes effectively. When you eat carbohydrates, they break down into glucose, which enters your bloodstream. In a healthy body, insulin helps move this glucose into cells for energy. However, with insulin resistance, this process becomes less efficient, leading to elevated blood sugar levels.
Studies show that diet and lifestyle changes can cut the risk of type 2 diabetes by over 60%. This remarkable statistic underscores the tremendous power you have to change your health trajectory through the choices you make every day.
The Importance of Weight Management
There is substantial evidence indicating that weight loss is highly effective in preventing progression from prediabetes to type 2 diabetes and in managing cardiometabolic health. Research from the Diabetes Prevention Program provides clear guidance on weight loss targets.
In the DPP, maximal prevention of diabetes over 4 years was observed at about 7–10% weight loss. This is consistent with studies where weight loss of 10% reduced incident diabetes by 79% over 2 years. For this reason, nutrition therapy to support a 7–10% weight loss is the appropriate goal in treating people with prediabetes.
For someone weighing 200 pounds, this translates to losing 14 to 20 pounds—a realistic and achievable goal that can dramatically reduce diabetes risk. Treatment plans should aim for at least 5–7% weight loss for people with overweight or obesity.
Focus on Whole, Nutrient-Dense Foods
The foundation of a prediabetes-friendly diet is choosing minimally processed, nutrient-rich foods. Eating patterns should emphasize 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 Every Meal
Non-starchy vegetables have few carbohydrates, so they have less impact on blood sugar. They’re nutritious and loaded with fiber, vitamins and minerals. Non-starchy vegetables include spinach, salad greens, cauliflower, broccoli, Brussels sprouts, asparagus, tomatoes, celery, and zucchini.
The ADA’s version of meal recommendations suggests these proportions: 50% of the plate filled with nonstarchy vegetables, such as leafy greens; 25% with healthy carbohydrates, such as whole grains like brown rice, farro or quinoa; 25% with lean protein, such as chicken, turkey, fish or tofu, not fried. This simple plate method makes meal planning straightforward and ensures balanced nutrition at every meal.
Non-starchy vegetables are incredibly versatile and can be incorporated into meals in countless ways. Try roasting Brussels sprouts with a drizzle of olive oil, adding spinach to morning omelets, creating colorful salads with mixed greens and tomatoes, or steaming broccoli as a side dish. The high fiber and water content of these vegetables helps you feel full and satisfied while keeping calories and carbohydrates in check.
Whole Fruits: Nature’s Sweet Treat
All types of fruit are OK and unlikely to be a problem for people who have prediabetes. However, how you consume fruit matters. For the most fiber benefit, eat whole fruits rather than drinking fruit juice. Whole fruits contain fiber that slows sugar absorption, while fruit juice lacks this benefit and can cause rapid blood sugar spikes.
Berries have been shown to be a healthy part of a prediabetes diet. Berries like blueberries, strawberries, raspberries, and blackberries are particularly beneficial because they’re rich in antioxidants and fiber while being relatively low in sugar compared to other fruits. Other excellent fruit choices include apples, oranges, pears, and peaches.
When incorporating fruit into your diet, consider pairing it with protein or healthy fat to further slow sugar absorption. For example, enjoy apple slices with almond butter, berries with Greek yogurt, or an orange with a handful of nuts. This combination helps maintain steady blood sugar levels while providing satisfying nutrition.
Understanding Carbohydrates and the Glycemic Index
Carbohydrates have the most direct impact on blood sugar levels, making them a crucial consideration in prediabetes management. However, evidence suggests that there is not an ideal percentage of calories from carbohydrate, protein, and fat for all people with or at risk for diabetes. The key is choosing the right types of carbohydrates and consuming them in appropriate portions.
Complex Carbohydrates vs. Simple Carbohydrates
Eating foods with complex carbohydrates can give your body the carbs it needs without that sugar dump brought by simple carbs. That’s because fiber-rich complex carbs take longer to digest to slow glucose absorption.
Complex carbohydrates include whole grains like oats, brown rice, quinoa, barley, and whole wheat products. They also include starchy vegetables like sweet potatoes and legumes such as beans, lentils, and chickpeas. These foods digest slowly and cause gradual increases in blood sugar, helping maintain stable energy levels throughout the day.
In contrast, simple carbohydrates found in refined grains and added sugars are quickly broken down and absorbed, causing rapid blood sugar spikes. Foods to minimize include added sugars and refined grains such as soda, juice, white bread, white rice, and pasta.
Using the Glycemic Index as a Guide
The glycemic index (GI) ranks foods based on how quickly they raise blood sugar levels. Foods that have a low GI, such as high fiber foods, are best for your blood sugar. Low GI foods (55 or below) include most non-starchy vegetables, legumes, whole grains, and many fruits.
Carbohydrate-rich foods with a high GI tend to have some combination of the following: high starch composition, low fiber, high sugar content, and low protein. Understanding these characteristics helps you make better food choices even without memorizing GI values.
Take note of the fiber content listed on the label to determine a food’s GI ranking. Added sugar and ingredients such as white flour can also add to the GI ranking, so looking for foods that have fewer of these on the nutrition label can help you choose lower GI foods.
It’s worth noting that brown rice, wheat pasta, and wheat bread typically only have 1 or 2 grams more fiber than white rice, white pasta, and white bread, so portion control remains important even with whole grain versions.
The Critical Role of Fiber
Fiber is essential for diabetes management and prevention. It slows the absorption of sugar, helping prevent blood sugar spikes, and supports gut health. Eating a fiber-rich diet can lower the risk of Type 2 diabetes and heart disease.
Fiber offers several benefits. It helps you feel full longer. It also adds bulk to your diet, making bowel movements easier to pass. Eating fiber-rich foods can make you less likely to overeat and help you avoid the crash that can come from eating a high sugar food.
Best Sources of Fiber
Examples of fiber foods include legumes like black beans, chickpeas, pinto beans, and lentils; nuts and seeds like almonds, pumpkin seeds, sunflower seeds, chia seeds, and flax seeds; vegetables like broccoli, cabbage, cauliflower, greens, kale, and onions; fruits like apples, blueberries, oranges, and raspberries; and whole grains like oats, whole grain bread, whole wheat pasta, and quinoa.
Try cereals with at least five grams of fiber per serving, whole fruits, vegetables and whole grains. Aim to gradually increase your fiber intake to 25-35 grams per day, making sure to drink plenty of water as you do so to help your digestive system adjust.
Incorporating fiber throughout the day is easier than you might think. Start your morning with oatmeal topped with berries and ground flaxseed. Add beans to soups and salads at lunch. Snack on raw vegetables with hummus or a handful of almonds. Include a generous serving of roasted vegetables with dinner. These simple additions can significantly boost your daily fiber intake.
Protein: Your Blood Sugar Stabilizer
Protein slows the rate carbohydrates enter your bloodstream, which works to keep blood sugar levels steady. According to the American Diabetes Association, eating two to three ounces of protein per meal has little to no impact on blood sugar levels among people who aren’t on insulin, including those with prediabetes. Because they take longer to digest compared to carbs, protein may help you feel fuller longer.
Lean Protein Sources
Both the ADA and the Dietary Guidelines for Americans recommend choosing lean protein, which has less unhealthy saturated fat. Excellent lean protein options include skinless chicken and turkey, fish and seafood, eggs, low-fat dairy products, legumes, tofu, and tempeh.
Skinless chicken is a lean protein that’s low in saturated fat. It’s great for those with prediabetes because it helps keep fat levels down while preserving muscle. Try grilling or baking it for a tasty addition to your meals.
Fish and Omega-3 Fatty Acids
Eat heart-healthy fish at least twice a week. Fish such as salmon, mackerel, tuna and sardines are rich in omega-3 fatty acids. These omega-3s may prevent heart disease. Wild-caught salmon is packed with protein and omega-3 fatty acids. These omega-3s can lower body inflammation. Chronic inflammation increases the risk of type 2 diabetes. Eating wild-caught salmon twice a week can help reduce this risk.
When preparing fish, opt for baking, grilling, broiling, or poaching rather than frying. Avoid fried fish, as the added fat and calories can undermine the health benefits. Season with herbs, lemon, and spices for flavor without adding unhealthy fats or excess sodium.
Plant-Based Proteins
For those with prediabetes, fiber-rich legumes are a great choice. Foods like black beans, lentils, and chickpeas are full of fiber and protein. This makes them great for keeping blood sugar levels stable.
Legumes can help with glucose control and lowering cholesterol. They’re incredibly versatile and can be added to salads, soups, stews, and grain bowls, or enjoyed as dips like hummus. Lentils are a great source of protein and fiber. They have a low glycemic index. This means they’re digested slowly, causing blood sugar to rise gradually.
Dairy and Prediabetes
Greek yogurt is full of protein and probiotics, which are good for digestion and gut health. A healthy gut is linked to better blood sugar control. Choose unflavored and unsweetened Greek yogurt to avoid added sugars.
Focus on protein-rich dairy like Greek yogurt, cheese, and cottage cheese, as they may help stabilize blood sugar levels and enhance satiety. The question of full-fat versus low-fat dairy intake is unresolved in terms of diabetes and cardiovascular risk, though low-fat may have a slight edge.
Healthy Fats: Essential for Optimal Health
When people get a prediabetes or type 2 diabetes diagnosis, they often think it is just about carbohydrates and especially sugar in their diet. However, it is important to also consider the type and quantity of dietary fat. Fats found in oils, butter, cheese, cream, meat, and fish can impact how well our bodies can handle the starch and sugars in our diet.
Research found that replacing even a small amount (5%) of saturated fat can improve blood sugar control. This highlights the importance of choosing the right types of fats in your diet.
Monounsaturated and Polyunsaturated Fats
Foods containing monounsaturated and polyunsaturated fats can help lower your cholesterol levels. Healthy fat sources include avocados, nuts (almonds, walnuts, pecans, cashews), seeds (chia, flax, pumpkin, sunflower), olive oil, canola oil, and fatty fish.
These healthy fats not only support heart health but also help with nutrient absorption and provide satiety. Use olive oil for cooking and salad dressings, add sliced avocado to sandwiches and salads, snack on a small handful of nuts, and sprinkle seeds on yogurt or oatmeal.
Fats to Limit
If you have prediabetes, eating a diet low in saturated fat and trans fat can help reduce your risk of developing heart disease. Saturated fats are found primarily in animal products like fatty cuts of meat, full-fat dairy, butter, and tropical oils like coconut and palm oil. Trans fats, found in some processed and fried foods, should be avoided entirely.
To reduce saturated fat intake, choose lean cuts of meat, remove visible fat and skin from poultry, opt for low-fat or fat-free dairy products, and limit processed meats like bacon, sausage, and hot dogs. Try to avoid or limit your intake of processed red meat, like bacon, salami, and hot dogs.
Limiting Added Sugars and Sweetened Beverages
Sugar can hide in less obvious places, including processed foods such as breakfast cereals, frozen meals, snacks, sauces and dressings. Though some sugar is necessary for your body to function, too much can worsen prediabetes.
The World Health Organization advises limiting added sugars to less than 10% of your total energy intake. For added health benefits, you would limit sugar calories to 5% or less of your total. For example, for someone on a 2,000-calorie daily diet, if they are following the 10% guideline, they would limit sugar calories to about 50 grams, which is about 12 teaspoons. For the 5%, they would stick to 25 grams, or about six teaspoons.
One can of soda contains about 32 grams of sugar, which is about eight teaspoons. This single beverage can exceed your entire daily sugar allowance, making it clear why limiting sugary drinks is so important.
The Problem with Sugary Beverages
Replace sugar-sweetened beverages with water as often as possible. Sweetened beverages such as sodas, sports drinks, juices and gourmet coffee shop creations account for some of the biggest concentrated sources of added sugar.
If you have prediabetes, it’s a good idea to limit or skip 100% fruit juice, soda, and sweetened coffee drinks. Try to avoid energy or sports drinks, mixed alcohol cocktails, and lemonade or sweet tea.
Water is always the beverage of choice for overall health. One study suggested that drinking more water can delay or prevent elevated blood glucose levels. Water also helps the kidneys work their best and prevents constipation.
The 2025 Standards emphasize 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.
Reading Labels for Hidden Sugars
Sugar appears on ingredient lists under many names, including high fructose corn syrup, cane sugar, brown sugar, honey, agave nectar, maple syrup, molasses, dextrose, maltose, and fruit juice concentrate. Learning to identify these various forms helps you make informed choices.
When reading nutrition labels, look at both the total sugars and added sugars. Total sugars include naturally occurring sugars (like those in fruit and milk) plus added sugars. The added sugars line tells you how much sugar was added during processing, which is what you want to minimize.
Mastering Portion Control
Paying attention to portion sizes can help you keep your diet low on the GI scale. Often, portion sizes in the United States are much larger than intended serving sizes. Controlling portion sizes helps prevent overeating and maintains blood sugar stability.
Practical Portion Control Strategies
Use smaller plates and bowls to naturally reduce portion sizes without feeling deprived. A standard dinner plate has grown from 9 inches to 12 inches over the past few decades, leading to larger servings. Using a 9-inch plate can help you serve appropriate portions while still filling your plate.
Measure servings, especially for carbohydrate-rich foods like grains, pasta, and starchy vegetables. A food scale or measuring cups can help you learn what appropriate portions look like. Over time, you’ll be able to estimate portions more accurately by sight.
Be mindful of hunger and fullness cues. Eat slowly, putting your fork down between bites, and stop eating when you feel satisfied rather than stuffed. It takes about 20 minutes for your brain to register fullness, so slowing down can prevent overeating.
Food labels can help you determine how much you’re actually eating. The label will list calories, fat, carbohydrates, and other nutritional information for a particular serving. If you eat more than the serving listed, it’s important to understand how that will affect the nutritional value.
Visual Portion Guides
Using your hand as a guide can help estimate portions when measuring isn’t practical. A serving of protein should be about the size of your palm, a serving of carbohydrates about the size of your cupped hand, a serving of fat about the size of your thumb, and vegetables can fill both hands cupped together.
The plate method mentioned earlier—filling half your plate with non-starchy vegetables, one quarter with lean protein, and one quarter with whole grains or starchy vegetables—provides built-in portion control while ensuring balanced nutrition.
Meal Timing and Frequency
Try to have your first meal within 1 to 2 hours of waking up. Blood sugar is easier to control when you eat on a schedule. Meals should be no more than 4 to 6 hours apart.
If meals are more than 4 to 6 hours apart or if you are more active than usual, a snack may help to keep your blood sugar more stable. Consistent meal timing helps regulate blood sugar levels and prevents extreme hunger that can lead to overeating.
Strategic Eating Patterns
Make your dinners light meals such as soup and/or salad. With prediabetes, it is important to reduce evening carbohydrate intake such as starches and sugary foods since we do not process the carbs as effectively in the later day.
Eat your veggies first. Try eating salad, vegetables, and proteins first. Simply eating these foods before your bread, pasta and other starches can improve your blood sugar control. This simple strategy can significantly impact post-meal blood sugar levels.
Avoid eating within 2-2.5 hours of going to bed. This allows your body time to digest food before sleep and can improve overnight blood sugar control.
Alcohol Consumption and Prediabetes
It is recommended that adults with diabetes or prediabetes who drink alcohol do so in moderation (one drink or less per day for adult women and two drinks or less per day for adult men).
Alcoholic beverages are a form of carbohydrate. In general, it’s best to consume alcohol in moderation or not at all, but it’s especially important if you’ve been diagnosed with prediabetes. Some cocktails may contain high amounts of sugar, which can cause blood sugar spikes.
If you’re going to drink, choose spirits with a no-calorie mixer or an option like light beer, seltzer or dry wine. They contain the fewest carbs. Avoid sugary mixed drinks, regular beer, and sweet wines, which can significantly impact blood sugar levels.
Popular Eating Patterns for Prediabetes
A “one-size-fits-all” eating plan is not evident for the prevention or management of diabetes. However, several eating patterns have shown benefits for people with prediabetes. The key is finding an approach that you can sustain long-term while meeting your nutritional needs and 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 emphasizes vegetables, fruits, whole grains, legumes, nuts, olive oil, and fish, with moderate amounts of poultry and dairy, and limited red meat and sweets.
The Mediterranean diet has been extensively studied and consistently shows benefits for blood sugar control, heart health, and weight management. It’s also one of the most enjoyable and sustainable eating patterns, featuring flavorful foods and flexible guidelines rather than strict rules.
DASH Diet
The Dietary Approaches to Stop Hypertension (DASH) diet was originally designed to lower blood pressure but has also shown benefits for blood sugar control. It emphasizes vegetables, fruits, whole grains, lean proteins, and low-fat dairy while limiting sodium, saturated fat, and added sugars. This eating pattern aligns well with prediabetes management goals.
Plant-Based Eating Patterns
Plant-based diets, including vegetarian and vegan approaches, can be beneficial for prediabetes management when well-planned. These eating patterns naturally emphasize fiber-rich foods, whole grains, legumes, vegetables, and fruits while limiting or eliminating animal products. The high fiber content and nutrient density support blood sugar control and weight management.
Lower-Carbohydrate Approaches
Some people with prediabetes benefit from reducing overall carbohydrate intake. Lower-carbohydrate eating patterns can range from moderate carbohydrate reduction to more restrictive approaches. The key is ensuring adequate nutrition from vegetables, proteins, and healthy fats while reducing refined carbohydrates and added sugars.
Any eating pattern you choose should be discussed with your healthcare provider or registered dietitian to ensure it meets your individual needs and health goals.
Working with Healthcare Professionals
Provide individualized medical nutrition therapy by referring people with prediabetes or diabetes to a registered dietitian nutritionist, preferably one who has comprehensive experience in diabetes care. Refer people with prediabetes and overweight/obesity to an intensive lifestyle intervention program that includes individualized goal-setting components, such as the Diabetes Prevention Program.
Strong evidence supports the efficacy and cost-effectiveness of nutrition therapy as a component of quality diabetes care, including its integration into the medical management of diabetes; therefore, it is important that all members of the health care team know and champion the benefits of nutrition therapy.
A registered dietitian nutritionist can provide personalized meal planning, help you navigate food choices, teach you how to read nutrition labels effectively, and support you in making sustainable dietary changes. They can also help you address any barriers to healthy eating and adjust your plan as your needs change.
The National Diabetes Prevention Program, recognized by the CDC, offers structured lifestyle change programs that have been proven effective in preventing or delaying type 2 diabetes. These programs typically include nutrition education, physical activity guidance, and behavioral strategies delivered over the course of a year.
Supplements and Prediabetes
Without underlying deficiency, the benefits of multivitamins or mineral supplements on glycemia for people with diabetes or prediabetes have not been supported by evidence, and therefore routine use is not recommended.
The routine use of chromium or vitamin D micronutrient supplements or any herbal supplements, including cinnamon, curcumin, or aloe vera, for improving glycemia in people with diabetes is not supported by evidence and is therefore not recommended.
While supplements are heavily marketed for blood sugar control, the evidence doesn’t support their use for most people with prediabetes. Focus on getting nutrients from whole foods, which provide a complex array of beneficial compounds that work together synergistically.
However, it is recommended that MNT for people taking metformin include an annual assessment of vitamin B12 status with guidance on supplementation options if deficiency is present. If you’re taking medications, discuss with your healthcare provider whether any specific supplements are appropriate for your situation.
Physical Activity: The Perfect Complement to Nutrition
Encourage an increase in moderate-intensity physical activity (brisk walking) for at least 150 minutes per week, with a weight-loss goal of 7% of initial body weight. Physical activity works synergistically with dietary changes to improve blood sugar control and prevent diabetes progression.
Walking for 20 minutes within a half hour of eating improves your blood sugar. This simple strategy can significantly reduce post-meal blood sugar spikes and is easy to incorporate into daily life. Even a short walk around the block after meals can make a difference.
Regular physical activity by itself or as part of a comprehensive lifestyle plan can prevent progression to type 2 diabetes in high-risk individuals. Aim for a combination of aerobic exercise (like walking, swimming, or cycling) and resistance training (like weight lifting or bodyweight exercises) for optimal benefits.
Practical Meal Planning and Preparation
Successful nutrition management requires planning and preparation. Taking time each week to plan meals, shop for groceries, and prepare food in advance can make healthy eating much easier and more sustainable.
Weekly Meal Planning
Set aside time each week to plan your meals and snacks. Consider your schedule, including busy days when you’ll need quick meals and days when you have more time to cook. Plan meals that use similar ingredients to reduce waste and simplify shopping.
Create a grocery list based on your meal plan and stick to it when shopping. Shopping the perimeter of the grocery store, where fresh produce, lean proteins, and dairy are typically located, can help you focus on whole foods while avoiding processed items in the center aisles.
Batch Cooking and Food Prep
Prepare components of meals in advance to make weeknight cooking faster and easier. Wash and chop vegetables, cook whole grains in batches, prepare lean proteins, and portion out snacks. Having healthy options ready to eat makes it much easier to stick with your nutrition goals when you’re busy or tired.
Invest in quality food storage containers to keep prepped foods fresh. Glass containers are ideal as they can go from refrigerator to microwave and don’t retain odors or stains like plastic.
Healthy Cooking Methods
The way you prepare food matters as much as what you eat. When you choose lean poultry, make sure it’s grilled, broiled, or roasted. Deep-fried or breaded options add extra fat and calories.
Healthy cooking methods include baking, roasting, grilling, broiling, steaming, sautéing with minimal oil, and slow cooking. These methods preserve nutrients while adding minimal fat. Experiment with herbs, spices, citrus, and vinegars to add flavor without relying on salt, sugar, or excessive fat.
Eating Out and Social Situations
Managing prediabetes doesn’t mean you can’t enjoy meals at restaurants or social gatherings. With some planning and smart strategies, you can navigate these situations while staying on track with your health goals.
Restaurant Strategies
Review the menu online before going to a restaurant so you can make a thoughtful choice without pressure. Look for grilled, baked, or steamed options rather than fried foods. Ask for dressings and sauces on the side so you can control portions. Request substitutions like extra vegetables instead of fries or a side salad instead of chips.
Don’t be afraid to ask questions about how food is prepared or request modifications. Most restaurants are happy to accommodate reasonable requests. Consider sharing an entrée or immediately boxing half for later, as restaurant portions are often much larger than needed.
Social Gatherings and Special Occasions
Before attending a party or gathering, eat a small, balanced snack so you’re not arriving hungry. This makes it easier to make thoughtful choices rather than overindulging. Survey all the food options before filling your plate, then choose your favorites while keeping portions reasonable.
Focus on socializing rather than eating. Position yourself away from the food table to reduce mindless snacking. Stay hydrated with water or unsweetened beverages. If you’re hosting, prepare healthy options that everyone can enjoy, proving that nutritious food can be delicious and satisfying.
Overcoming Common Challenges
Making dietary changes isn’t always easy. Understanding common challenges and having strategies to address them can help you stay on track.
Managing Cravings
Cravings are normal and don’t mean you lack willpower. When a craving hits, first check if you’re actually hungry or if you’re eating for another reason like stress, boredom, or habit. If you’re truly hungry, have a balanced snack. If not, try drinking water, going for a walk, or engaging in another activity.
If you’re craving something specific, allow yourself a small portion rather than trying to ignore it completely. Deprivation often leads to overindulgence later. The key is moderation and mindfulness, not perfection.
Dealing with Setbacks
Everyone has days when they don’t eat as planned. Rather than viewing this as failure, see it as a learning opportunity. What triggered the deviation from your plan? What could you do differently next time? Then move forward without guilt or self-criticism.
One less-than-ideal meal or day doesn’t undo your progress. What matters is your overall pattern of eating over time. Get back on track with your next meal rather than waiting until tomorrow or Monday.
Budget Considerations
Eating healthy doesn’t have to be expensive. Buy produce that’s in season when it’s most affordable. Frozen vegetables and fruits are nutritious, convenient, and often less expensive than fresh. Buy whole grains, beans, and lentils in bulk. Choose less expensive protein sources like eggs, canned fish, chicken thighs, and plant-based proteins.
Plan meals around sales and use coupons when available. Reduce food waste by using leftovers creatively and storing food properly. Growing your own herbs or vegetables, even in small containers, can save money while providing fresh produce.
Monitoring Progress and Staying Motivated
People with prediabetes should be vigilant about their laboratory test results. Know your ABCs—that’s A1C, blood pressure and cholesterol. And if you’re at risk or have prediabetes, make sure you follow up with your A1C level with a blood test at least yearly.
Track your progress beyond just the scale. Notice improvements in energy levels, sleep quality, mood, and how your clothes fit. Celebrate non-scale victories like choosing a healthy meal when eating out, trying a new vegetable, or walking after dinner consistently for a week.
Keep a food journal to increase awareness of your eating patterns. This doesn’t have to be complicated—even a simple note on your phone about what you ate and how you felt can provide valuable insights. Review your journal periodically to identify patterns and areas for improvement.
Set realistic, specific goals. Instead of “eat healthier,” try “include a vegetable with lunch and dinner five days this week” or “replace afternoon soda with water.” Small, achievable goals build confidence and create sustainable habits.
The Importance of Sleep and Stress Management
Sleep deprivation has been shown to increase people’s cravings for sugary foods. People with prediabetes should make sure they’re getting seven to eight hours of sleep a night.
Poor sleep affects hormones that regulate hunger and fullness, making it harder to make healthy food choices. Prioritize good sleep hygiene by maintaining a consistent sleep schedule, creating a relaxing bedtime routine, keeping your bedroom cool and dark, and limiting screen time before bed.
Chronic stress can also impact blood sugar levels and eating behaviors. Many people turn to food for comfort when stressed. Develop healthy stress management techniques like deep breathing, meditation, yoga, spending time in nature, or engaging in hobbies you enjoy. Regular physical activity is also an excellent stress reliever.
Building a Support System
Making lifestyle changes is easier with support. Share your goals with family and friends who can encourage you. Consider joining a diabetes prevention program or support group where you can connect with others facing similar challenges.
If family members do the grocery shopping or cooking, involve them in your meal planning and help them understand your nutritional needs. When everyone in the household eats similarly, it’s much easier to stick with healthy habits.
Find an accountability partner—someone who will check in with you regularly about your progress and challenges. This could be a friend, family member, or someone from a support group. Knowing someone else is invested in your success can provide powerful motivation.
Looking Forward: The Path to Reversing Prediabetes
If you’ve been diagnosed with prediabetes, progressing to diabetes is not a given. The key to warding off progression of prediabetes is a balanced approach to diet. People with prediabetes do not have to eliminate entire food groups. 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. We encourage making gradual behavior changes.
The journey to better health is not about perfection but about progress. Each healthy choice you make—whether it’s choosing water over soda, adding vegetables to your meal, taking a walk after dinner, or getting adequate sleep—contributes to better blood sugar control and reduced diabetes risk.
Remember that sustainable change happens gradually. Focus on adding healthy foods and behaviors rather than only restricting and eliminating. This positive approach is more enjoyable and sustainable long-term. As healthy choices become habits, they require less conscious effort and become your new normal.
Stay informed about your health by maintaining regular contact with your healthcare team. Schedule follow-up appointments to monitor your blood sugar, weight, blood pressure, and cholesterol. Celebrate improvements and discuss any challenges you’re facing. Your healthcare providers are partners in your health journey and can provide guidance, support, and adjustments to your plan as needed.
