Managing blood sugar levels effectively is one of the most important steps you can take to protect your overall health and well-being. Whether you’re living with diabetes, prediabetes, or simply want to maintain optimal metabolic health, the lifestyle choices you make each day have a profound impact on your blood glucose control. When you have diabetes, it’s important to keep your blood sugar levels within the range recommended by your healthcare professional, but many things can make your blood sugar levels change, sometimes quickly. Understanding how to adjust your daily habits can help you maintain stable blood glucose levels, prevent serious complications, and improve your quality of life.
More than 115 million Americans have prediabetes, and the vast majority don’t know it. This staggering statistic underscores the importance of blood sugar awareness and proactive lifestyle management. Since it’s a borderline condition — higher than normal blood sugar, but not to the level of diabetes — eating a healthful diet and making moderate lifestyle changes can help people improve their blood sugar levels to prevent the onset of type 2 diabetes and its serious health impacts. The good news is that with the right approach, you have significant control over your blood sugar levels through everyday choices.
Understanding Blood Sugar and Why It Matters
Before diving into specific lifestyle adjustments, it’s essential to understand what blood sugar is and why maintaining healthy levels is so critical. Blood glucose, or blood sugar, is the main source of energy for your body’s cells. It comes primarily from the foods you eat, particularly those containing carbohydrates. Your body uses a hormone called insulin to help transport glucose from your bloodstream into your cells, where it can be used for energy.
When this system works properly, your blood sugar levels remain within a healthy range. However, when you have diabetes or insulin resistance, this delicate balance is disrupted. In type 1 diabetes, the body doesn’t produce enough insulin. In type 2 diabetes, the body either doesn’t produce enough insulin or doesn’t use it effectively—a condition known as insulin resistance. Without proper management, chronically elevated blood sugar levels can lead to serious complications affecting your heart, kidneys, eyes, nerves, and other vital organs.
Keep your blood sugar levels in your target range as much as possible. This will help you prevent or delay serious health problems. Understanding your target blood sugar ranges is the first step. Before a meal: 80 to 130 mg/dL. Two hours after the start of a meal: Less than 180 mg/dL. However, these targets may vary based on your individual circumstances, so it’s important to work with your healthcare team to establish personalized goals.
The Foundation: Dietary Changes for Blood Sugar Control
Diet is arguably the most powerful tool you have for managing blood sugar levels. When you have diabetes, you need to know how foods affect your blood sugar levels. The foods you choose, the portions you eat, and even the timing of your meals all play crucial roles in blood glucose regulation. Let’s explore the key dietary strategies that can help you maintain stable blood sugar levels throughout the day.
Understanding the Glycemic Index and Glycemic Load
One of the most valuable tools for making smart food choices is understanding the glycemic index (GI) and glycemic load (GL). Glycemic index (GI) is a measure of how quickly a food can make your blood sugar (glucose) rise. Foods are ranked on a scale from 0 to 100, with pure glucose assigned a value of 100.
Eating low GI foods can help you gain tighter control over your blood sugar. Paying attention to the GI of foods can be another tool to help manage your diabetes, along with carbohydrate counting. Low-GI foods (55 or below) cause a slower, more gradual rise in blood sugar, while high-GI foods (70 or above) trigger rapid spikes.
However, the glycemic index alone doesn’t tell the whole story. To focus on this problem, researchers developed the idea of glycemic load (GL). This number shows the effect on blood sugar levels when you eat a common portion of the food. For example, watermelon has a high GI but a low GL because it contains relatively little carbohydrate per serving—it’s mostly water and fiber.
Choosing low GI foods like whole grains, legumes and non-starchy vegetables may help maintain stable blood sugar levels. Some excellent low-GI food choices include:
- Most fruits and vegetables, especially berries, apples, pears, and citrus fruits
- Whole grains such as oats, quinoa, and barley
- Legumes including beans, lentils, and chickpeas
- Nuts and seeds
- Non-starchy vegetables like leafy greens, broccoli, peppers, and tomatoes
- Low-fat dairy products
High-GI foods (with scores of 70 or higher) include white rice, white bread, pretzels, white bagels, white baked potatoes, crackers, sugar-sweetened beverages and (surprisingly) watermelon! While you don’t need to eliminate these foods entirely, being mindful of portion sizes and combining them with lower-GI foods can help moderate their impact on your blood sugar.
Modern Dietary Approaches: What the Latest Research Shows
The landscape of dietary recommendations for blood sugar management has evolved significantly in recent years. The new guidelines propose a range of potential eating patterns that fall under the broader umbrella of low-carbohydrate/lower starch diets, including the Mediterranean, plant-based, and the Dietary Approaches to Stop Hypertension (DASH) diet as options that can support patients’ overall health, depending on individual clinical and family history.
Lifestyle interventions remain foundational, with referral to diabetes prevention programs targeting 5–7% weight loss. Mediterranean and lower-carbohydrate eating patterns have the strongest evidence. This represents a shift from older recommendations that favored small, frequent high-carbohydrate meals. The focus now is on personalized nutrition that takes into account your individual preferences, cultural background, and health goals.
The Mediterranean diet, in particular, has shown impressive results for blood sugar management. This eating pattern emphasizes:
- Abundant vegetables, fruits, whole grains, and legumes
- Healthy fats from olive oil, nuts, and fatty fish
- Moderate amounts of fish and poultry
- Limited red meat and processed foods
- Herbs and spices instead of salt for flavoring
The Plate Method: A Simple Approach to Balanced Meals
Creating balanced meals is one of the most effective ways to manage blood sugar. Following the Plate Method makes it easy to create balanced meal. This visual approach takes the guesswork out of portion control and ensures you’re getting the right balance of nutrients at each meal.
For this method, divide your plate using the following measurements: ½ plate: Non-starchy vegetables, such as spinach, broccoli, carrots, or peppers. ¼ plate: Lean protein, such as chicken, fish, eggs, or beans. The remaining quarter of your plate should contain carbohydrates, preferably whole grains or starchy vegetables. This simple formula helps ensure you’re getting plenty of fiber and nutrients while keeping carbohydrate portions in check.
Balancing carbohydrates with protein and fiber helps slow digestion and reduce blood sugar spikes after meals. Protein and fiber also help you feel full longer, which may prevent overeating and support better portion control. This is why combining foods strategically is so important—it’s not just about what you eat, but how you combine different foods together.
The Power of the “Protein Dam”
One particularly effective strategy for managing blood sugar spikes is what nutritionists call building a “protein dam.” Combining protein with carbs helps slow down the absorption of sugar into the blood, reducing or eliminating spikes. This simple technique can make a significant difference in your post-meal blood sugar levels.
Eating protein and/or vegetables with carbs creates a meal where, by default, you’re consuming fewer carbs. For example, if you’re having toast for breakfast, pair it with eggs or Greek yogurt. If you’re eating pasta, add plenty of vegetables and a lean protein source. This approach allows you to enjoy a wider variety of foods while maintaining better blood sugar control.
Foods to Limit or Avoid
The main takeaway for prediabetics: Eat fewer carbs, especially refined carbs. These include sugary foods and beverages, white bread, white rice, and white pasta, which offer minimal or no nutrients or fiber, are absorbed quickly, and typically spike your blood sugar.
Foods and beverages that can cause problematic blood sugar spikes include:
- Sugar-sweetened beverages like soda, sweet tea, and fruit juice
- Refined grains such as white bread, white rice, and regular pasta
- Pastries, cookies, cakes, and other baked goods made with refined flour and sugar
- Candy and other concentrated sweets
- Processed snack foods like chips and crackers
- Sweetened breakfast cereals
Choose foods lower in calories, saturated fat, sugar, and salt. This doesn’t mean you can never enjoy these foods, but they should be occasional treats rather than dietary staples. When you do indulge, keep portions small and pair them with protein, healthy fats, or fiber-rich foods to minimize their impact on your blood sugar.
The Importance of Meal Timing and Consistency
Eat at regular times, and don’t skip meals. Maintaining a consistent eating schedule helps regulate your blood sugar levels throughout the day. When you skip meals, especially if you’re taking diabetes medications, you risk experiencing dangerous drops in blood sugar. On the other hand, eating at irregular times can make it harder for your body to regulate glucose effectively.
Aim to eat breakfast, lunch, and dinner at roughly the same times each day, with healthy snacks in between if needed. This consistency helps your body anticipate when food is coming and can improve insulin sensitivity over time. If you take insulin or certain diabetes medications, coordinating your meals with your medication schedule is especially important.
Adding Color to Your Plate
Eating a variety of colorful foods is an easy way to improve overall nutrition and support blood sugar management. Different color foods provide different vitamins, minerals, and antioxidants that support overall health and body function. Many colorful fruits and vegetables are rich in fiber, which helps slow glucose absorption.
Try to include at least three different colors on your plate at each meal. Spring and summer offer abundant options like red strawberries and tomatoes, orange carrots and sweet potatoes, green spinach and asparagus, purple eggplant and cabbage, and yellow squash and peppers. These colorful plant foods not only provide essential nutrients but also contain phytochemicals that may help improve insulin sensitivity and reduce inflammation.
Hydration and Blood Sugar
Staying hydrated is important for maintaining healthy blood sugar levels and overall body function. Water helps the body regulate blood glucose and remove excess sugar through urine. Dehydration can lead to higher blood sugar levels and increased fatigue.
Drink water instead of juice or soda. Water should be your primary beverage throughout the day. If you find plain water boring, try infusing it with fresh fruit, cucumber, or herbs like mint or basil. Unsweetened tea and coffee (in moderation) are also good choices. Avoid or strictly limit sugary drinks, which can cause rapid blood sugar spikes and provide empty calories without nutritional value.
Physical Activity: Moving Your Way to Better Blood Sugar Control
Exercise is one of the most powerful tools for managing blood sugar levels, and its benefits extend far beyond glucose control. Physical activity helps the body use glucose more effectively by increasing insulin sensitivity. This means your body can move sugar from the blood into the cells more efficiently. Regular physical activity can help you achieve and maintain a healthy weight, reduce your risk of cardiovascular disease, improve your mood, and enhance your overall quality of life.
How Exercise Affects Blood Sugar
When you exercise, your muscles need more energy, so they pull glucose from your bloodstream to use as fuel. This process happens even if you don’t have enough insulin available, which is why physical activity can lower blood sugar levels independently of insulin. Additionally, regular exercise makes your cells more sensitive to insulin, meaning they can use available insulin more effectively to take up glucose from the blood.
The effects of exercise on blood sugar can last for hours or even days after your workout. This is why consistency is so important—regular physical activity provides ongoing benefits for blood sugar management, while sporadic exercise offers only temporary improvements.
How Much Exercise Do You Need?
Current guidelines recommend at least 150 minutes of moderate-intensity aerobic activity per week for adults with diabetes or prediabetes. This breaks down to about 30 minutes of activity on most days of the week. However, you don’t need to do all 30 minutes at once—breaking it into shorter sessions of 10 or 15 minutes throughout the day can be just as effective.
Moderate-intensity activities include:
- Brisk walking
- Swimming or water aerobics
- Cycling on level terrain or with few hills
- Doubles tennis
- Dancing
- Gardening and yard work
- Recreational activities like hiking or recreational sports
You should be able to talk but not sing during moderate-intensity exercise. If you’re just starting an exercise program, begin slowly and gradually increase your duration and intensity over time. Even small amounts of activity are better than none, and every step counts toward better blood sugar control.
The Power of Post-Meal Movement
Take a 10–15-minute walk after meals. Even small amounts of movement after eating can help lower blood sugar levels and improve energy. This simple habit can be remarkably effective at blunting post-meal blood sugar spikes. The timing is important—moving within 30 minutes to an hour after eating provides the greatest benefit.
You don’t need to do vigorous exercise after meals. A gentle walk around your neighborhood, some light stretching, or even doing household chores can help. The key is to get your muscles moving so they start using the glucose that’s entering your bloodstream from your meal.
Incorporating Strength Training
While aerobic exercise gets most of the attention for blood sugar management, strength training is equally important. Building muscle mass improves your body’s ability to use glucose because muscle tissue is metabolically active and uses glucose for energy. Aim to include resistance training exercises at least two days per week, working all major muscle groups.
Strength training doesn’t require a gym membership or expensive equipment. Bodyweight exercises like push-ups, squats, lunges, and planks are highly effective. Resistance bands, dumbbells, or even household items like water bottles or canned goods can provide the resistance you need to build strength.
Making Movement Part of Your Daily Life
Spring is the perfect time to get outside and move more. Simple exercise suggestions include the following: Spend time gardening or doing yard work. Play outside with family or participate in outdoor activities. The best exercise is the one you’ll actually do consistently, so find activities you enjoy.
Look for opportunities to add more movement throughout your day:
- Take the stairs instead of the elevator
- Park farther away from store entrances
- Stand or walk while talking on the phone
- Do stretches or exercises during TV commercial breaks
- Walk to nearby destinations instead of driving
- Use a standing desk or take regular breaks to stand and move if you have a sedentary job
- Play active games with children or grandchildren
- Join a recreational sports league or walking group
Exercise Safety Considerations
If you take insulin, you may need to lower your insulin dose before you exercise. You also may need to watch your blood sugar level closely for several hours after intense activity. Exercise can sometimes cause blood sugar to drop too low, especially if you take insulin or certain diabetes medications. Check your blood sugar before, during (for longer workouts), and after exercise to understand how different activities affect you.
If your blood sugar is below 100 mg/dL before exercise, have a small snack containing 15-30 grams of carbohydrates to prevent hypoglycemia. Always carry a fast-acting source of glucose like glucose tablets, juice, or candy when exercising, especially if you take insulin or medications that can cause low blood sugar. If you have any complications from diabetes, such as nerve damage or heart disease, talk to your healthcare provider about which types of exercise are safest for you.
Monitoring Your Blood Sugar: Knowledge Is Power
Regular blood sugar monitoring is essential for understanding how your body responds to different foods, activities, medications, and stressors. Keep track of your blood sugar to see what makes it go up or down. This information empowers you to make informed decisions about your lifestyle and helps you and your healthcare team adjust your management plan as needed.
Traditional Blood Glucose Monitoring
Use a blood sugar meter (also called a glucometer) or a continuous glucose monitor (CGM) to check your blood sugar. A blood sugar meter measures the amount of sugar in a small sample of blood, usually from your fingertip. Traditional fingerstick testing has been the standard for decades and remains an important tool for many people with diabetes.
How often you need to check depends on your type of diabetes, your treatment plan, and how well controlled your blood sugar is. If you have type 1 diabetes, have type 2 diabetes and take insulin, or often have low blood sugar, your doctor may want you to check your blood sugar more often, such as before and after you’re physically active. Common testing times include when you first wake up, before meals, two hours after meals, before bed, and before and after exercise.
Continuous Glucose Monitoring: A Game-Changer
Continuous glucose monitoring (CGM) technology has revolutionized diabetes management in recent years. A CGM uses a sensor inserted under the skin to measure your blood sugar every few minutes. This provides a comprehensive picture of your glucose patterns throughout the day and night, revealing trends that fingerstick testing might miss.
Technology, including CGM and AID, is now recommended soon after diagnosis in both type 1 and type 2 diabetes, with fewer restrictions. This represents a significant shift in diabetes care philosophy. The 2026 ADA Standards of Care recommend CGM use at diabetes onset and at any point thereafter to improve outcomes. They are also recommending the removal of the insulin use tied to CGM use. This means more people can benefit from this technology, regardless of whether they use insulin.
If your budget allows, I would recommend wearing a CGM at least once to learn how your blood sugar level responds to the foods you eat and which combinations of foods allow for better management of your blood sugar. With a CGM, the data is right there on your phone. Many people find that seeing their glucose levels in real-time helps them make better food and activity choices in the moment.
Understanding Your Numbers
Knowing what your blood sugar numbers mean is crucial for effective management. Blood sugar below 70 mg/dL is considered low. Low blood sugar, or hypoglycemia, requires immediate treatment with fast-acting carbohydrates. Symptoms include shakiness, sweating, confusion, rapid heartbeat, and dizziness.
On the other end of the spectrum, consistently high blood sugar levels indicate that your management plan needs adjustment. If you’re sick and your blood sugar is 240 mg/dL or above, you may need to check for ketones, which can indicate a dangerous condition called diabetic ketoacidosis.
Beyond daily blood sugar readings, your healthcare provider will likely monitor your A1C level, which reflects your average blood sugar over the past 2-3 months. If an A1C test indicates you have prediabetes (with an A1C of 5.7 percent to 6.4 percent) please consult with your doctor. For people with diabetes, the A1C target is typically below 7%, though individual goals may vary.
Tracking Patterns and Trends
Track your food, drink, and physical activity. Keeping a log of your blood sugar readings along with information about what you ate, how much you exercised, your stress levels, and any medications you took can help you identify patterns. You might notice that certain foods consistently spike your blood sugar, or that stress affects your levels more than you realized.
Many blood glucose meters and CGM systems come with apps that make tracking easier. These apps can generate reports showing your glucose patterns over time, which can be invaluable when meeting with your healthcare team. Look for trends rather than focusing on individual readings—one high or low number doesn’t define your overall control.
The Critical Role of Sleep in Blood Sugar Regulation
Sleep is often overlooked in discussions about blood sugar management, but it plays a crucial role in metabolic health. Poor sleep quality and insufficient sleep duration can significantly impact your blood sugar levels and insulin sensitivity. When you don’t get enough quality sleep, your body produces more stress hormones like cortisol, which can raise blood sugar levels. Additionally, sleep deprivation affects the hormones that regulate hunger and fullness, often leading to increased appetite and cravings for high-carbohydrate foods.
How Much Sleep Do You Need?
Most adults need 7-9 hours of quality sleep per night for optimal health. However, it’s not just about quantity—sleep quality matters too. Interrupted sleep or poor sleep quality can have similar negative effects on blood sugar as insufficient sleep duration. People with diabetes are at higher risk for sleep disorders like sleep apnea, which can further complicate blood sugar management.
Improving Your Sleep Quality
To improve your sleep and support better blood sugar control:
- Maintain a consistent sleep schedule, going to bed and waking up at the same times each day, even on weekends
- Create a relaxing bedtime routine to signal your body it’s time to wind down
- Keep your bedroom cool, dark, and quiet
- Avoid screens (phones, tablets, computers, TV) for at least an hour before bed, as blue light can interfere with melatonin production
- Limit caffeine intake, especially in the afternoon and evening
- Avoid large meals close to bedtime, though a small protein-rich snack may help prevent overnight blood sugar drops
- Get regular physical activity, but not too close to bedtime
- Manage stress through relaxation techniques like meditation or deep breathing
If you snore loudly, wake up gasping for air, or feel excessively tired during the day despite seemingly adequate sleep, talk to your healthcare provider about being evaluated for sleep apnea. This condition is common in people with type 2 diabetes and can significantly impact blood sugar control when left untreated.
Stress Management: The Hidden Factor in Blood Sugar Control
Stress is an inevitable part of life, but chronic stress can wreak havoc on your blood sugar levels. When you’re sick, your body makes stress-related hormones that help fight the illness. But those hormones also can raise your blood sugar. This same mechanism occurs with psychological stress—your body releases hormones like cortisol and adrenaline that cause your liver to release stored glucose, raising your blood sugar levels.
Additionally, stress can affect blood sugar indirectly by influencing your behaviors. When you’re stressed, you may be more likely to skip exercise, make poor food choices, forget to take medications, or neglect blood sugar monitoring. Understanding the connection between stress and blood sugar is the first step toward managing both effectively.
Effective Stress Management Techniques
Developing healthy stress management strategies is essential for blood sugar control. Different techniques work for different people, so experiment to find what helps you most:
Mindfulness and Meditation: Regular mindfulness practice can help reduce stress hormones and improve blood sugar control. Even just 10-15 minutes of meditation daily can make a difference. Apps like Headspace, Calm, or Insight Timer offer guided meditations specifically for stress reduction.
Deep Breathing Exercises: Simple breathing techniques can activate your body’s relaxation response. Try the 4-7-8 technique: breathe in for 4 counts, hold for 7 counts, and exhale for 8 counts. Repeat several times when you feel stressed.
Progressive Muscle Relaxation: This technique involves tensing and then relaxing different muscle groups throughout your body, helping release physical tension that accompanies stress.
Physical Activity: Exercise is one of the most effective stress relievers, with the added benefit of directly improving blood sugar control. Activities like yoga combine physical movement with mindfulness for double benefits.
Social Connection: Spending time with supportive friends and family can help buffer the effects of stress. Don’t hesitate to reach out for support when you’re feeling overwhelmed.
Time Management: Often, stress comes from feeling overwhelmed by too many commitments. Learning to prioritize, delegate, and say no when necessary can significantly reduce stress levels.
Professional Support: If stress or anxiety is significantly impacting your life and blood sugar control, consider working with a mental health professional. Cognitive-behavioral therapy and other therapeutic approaches can be highly effective for managing stress and improving diabetes self-care.
Weight Management and Blood Sugar Control
For many people with type 2 diabetes or prediabetes, achieving and maintaining a healthy weight is one of the most powerful interventions for blood sugar control. Even modest weight loss can significantly improve insulin sensitivity and blood glucose levels. Lifestyle interventions remain foundational, with referral to diabetes prevention programs targeting 5–7% weight loss. This relatively modest goal—just 10-15 pounds for someone weighing 200 pounds—can produce meaningful health benefits.
Why Weight Matters for Blood Sugar
Excess body weight, particularly around the abdomen, is closely linked to insulin resistance. Fat cells, especially visceral fat that surrounds your organs, produce hormones and inflammatory substances that interfere with insulin’s ability to work effectively. When you lose weight, particularly visceral fat, your cells become more responsive to insulin, making it easier to maintain healthy blood sugar levels.
For some people with type 2 diabetes, significant weight loss can even lead to diabetes remission, meaning blood sugar levels return to normal without the need for diabetes medications. While not everyone will achieve remission, virtually everyone who loses weight will see improvements in blood sugar control.
Sustainable Approaches to Weight Loss
The key to successful weight loss is finding an approach you can maintain long-term. Crash diets and extreme restrictions rarely lead to lasting results. Instead, focus on making gradual, sustainable changes to your eating and activity habits:
Control your food portions (for example, use the plate method). Portion control is often more important than eliminating specific foods. Using smaller plates, measuring portions until you develop a good eye for serving sizes, and being mindful of restaurant portions (which are often 2-3 times larger than appropriate) can help you reduce calorie intake without feeling deprived.
The dietary strategies discussed earlier—emphasizing low-GI foods, following the plate method, eating plenty of vegetables, choosing lean proteins, and limiting processed foods—naturally support weight loss while improving blood sugar control. Following a low-GI diet also may help with weight loss. Low-GI foods tend to be more filling and satisfying, helping you feel full on fewer calories.
Regular physical activity is crucial for weight management. While diet is typically more important for weight loss, exercise helps preserve muscle mass during weight loss, increases your metabolic rate, and makes it easier to maintain weight loss long-term. Aim for a combination of aerobic exercise and strength training for best results.
When to Consider Additional Support
“The updates reinforce that lifestyle and behavioral support are foundational, not optional,” according to diabetes experts. If you’re struggling to lose weight through lifestyle changes alone, don’t hesitate to seek additional support. Options include:
- Working with a registered dietitian who specializes in diabetes
- Joining a structured diabetes prevention or weight management program
- Participating in support groups, either in-person or online
- Discussing weight loss medications with your healthcare provider
- In some cases, considering bariatric surgery for significant obesity
In addition to managing blood sugar, blood pressure, and cholesterol levels, recommendations include using GLP-1 and similar medicines (such as Ozempic and Mounjaro) and SGLT-2 inhibitors (like Jardiance and Farxi for comprehensive metabolic health management. These newer medications can support both blood sugar control and weight loss in appropriate candidates.
The Importance of Comprehensive Health Management
While blood sugar control is crucial, it’s important to remember that diabetes management involves more than just glucose levels. The new guidelines take a broader approach to long-term health, recognizing that heart disease, kidney disease, and diabetes as · interconnected conditions that require coordinated approaches for prevention and treatment. This holistic perspective is essential for preventing complications and maintaining overall health.
Blood Pressure Management
blood pressure goals, recommending levels below 130/80 mmHg for most people with diabetes, and aiming for even lower systolic blood pressure (the top number, representing peak pressure in your arteries) when it can be done safely. High blood pressure is common in people with diabetes and significantly increases the risk of heart disease, stroke, and kidney disease.
Many of the lifestyle changes that improve blood sugar also benefit blood pressure: maintaining a healthy weight, exercising regularly, limiting sodium intake, eating plenty of fruits and vegetables, limiting alcohol, and managing stress. If lifestyle changes aren’t enough to control your blood pressure, medications may be necessary.
Cholesterol and Heart Health
People with diabetes have a significantly higher risk of cardiovascular disease. Managing cholesterol levels through diet, exercise, and medications when needed is crucial for reducing this risk. Focus on eating healthy fats from sources like olive oil, nuts, avocados, and fatty fish while limiting saturated fats from red meat and full-fat dairy products. Avoid trans fats entirely.
Regular Health Screenings
Regular check-ups and screenings are essential for catching and addressing complications early. People with diabetes should have:
- A1C tests at least twice yearly, or more often if not meeting targets
- Annual comprehensive eye exams to screen for diabetic retinopathy
- Regular kidney function tests
- Annual foot exams to check for nerve damage and circulation problems
- Regular dental check-ups, as diabetes increases the risk of gum disease
- Cardiovascular risk assessments
- Screening for depression, which is more common in people with diabetes
Medication Management and Blood Sugar Control
Insulin and other diabetes medicines are designed to lower blood sugar levels when diet and exercise alone don’t help enough. How well these medicines work depends on the timing and size of the dose. While lifestyle changes are foundational, many people with diabetes also need medications to achieve optimal blood sugar control.
Taking Medications as Prescribed
If your healthcare provider prescribes diabetes medications, it’s crucial to take them exactly as directed. Keep taking your diabetes medicine. But call your healthcare professional if you can’t eat because of an upset stomach or vomiting. Never stop or adjust your medications without consulting your healthcare team, even if your blood sugar levels improve with lifestyle changes.
Store insulin properly. Insulin that is not stored properly or is past its expiration date may not work. Follow storage instructions carefully, and check expiration dates regularly. Keep track of when you open insulin vials or pens, as they typically expire 28 days after opening, even if stored properly.
Communicating with Your Healthcare Team
Tell your healthcare professional about any medicine problems. If your diabetes medicines cause your blood sugar level to drop too low, the dosage or timing may need to be changed. Your healthcare professional also might adjust your medicine if your blood sugar stays too high. Open communication with your healthcare team is essential for optimizing your treatment plan.
Be cautious with new medicines. Talk with your healthcare team or pharmacist before you try new medicines. That includes medicines sold without a prescription and those prescribed for other medical conditions. Ask how the new medicine might affect your blood sugar levels and any diabetes medicines you take. Many medications, including some over-the-counter drugs, can affect blood sugar levels.
Special Considerations: Managing Blood Sugar During Illness
With diabetes, it’s important to be prepared for times of illness. When you’re sick, managing blood sugar becomes more challenging but also more important. Illness causes physical stress that triggers the release of stress hormones, which can raise blood sugar levels even if you’re eating less than usual.
Creating a Sick Day Plan
Plan ahead. Work with your healthcare team to make a plan for sick days. Include instructions on what medicines to take and how to adjust your medicines if needed. Also note how often to measure your blood sugar. Your sick day plan should include:
- How often to check blood sugar (usually more frequently than normal)
- When to check for ketones
- Which medications to continue and which to adjust
- What to eat and drink when you don’t feel well
- Which over-the-counter medications are safe to use
- When to call your healthcare provider
- Warning signs that require immediate medical attention
It’s important to call if you run a fever over 101 degrees Fahrenheit (38.3 degrees Celsius) for 24 hours. Other reasons to contact your healthcare provider during illness include persistent vomiting or diarrhea, blood sugar levels consistently above 240 mg/dL, presence of ketones in your urine, difficulty breathing, or confusion.
Diabetes Self-Management Education and Support
Under these guidelines, people with diabetes would also engage in diabetes self-management education and support (DSMES), and well-rounded care includes a mix of diabetes education, blood glucose monitoring, and comorbidity management. Diabetes self-management education and support (DSMES) programs provide structured education and ongoing support to help you develop the knowledge, skills, and confidence needed to manage your diabetes effectively.
DSMES programs are typically led by certified diabetes care and education specialists who can teach you about:
- Understanding diabetes and how it affects your body
- Healthy eating and meal planning
- Physical activity and exercise
- Blood glucose monitoring and interpreting results
- Taking medications correctly
- Problem-solving and coping with challenges
- Reducing risks of complications
- Healthy coping with the emotional aspects of diabetes
Ask your healthcare provider for a referral to a DSMES program. Many insurance plans, including Medicare, cover these services. Even if you’ve had diabetes for years, DSMES can help you learn new strategies and stay motivated in your self-care efforts.
Leveraging Technology for Better Blood Sugar Management
Technology is transforming diabetes management, making it easier than ever to track, understand, and control blood sugar levels. Resources for managing diabetes are getting smarter, more flexible and more commercially available. New technology, updated guidance and growing awareness help more people find a care plan that empowers them to live their healthiest lives with diabetes.
Continuous Glucose Monitors and Apps
Modern CGM systems connect to smartphone apps that display your glucose levels in real-time, show trends with directional arrows, and can alert you when your glucose is going too high or too low. These systems provide invaluable data that can help you understand how different foods, activities, and situations affect your blood sugar.
In recent years, following over-the-counter device approval, a wider segment of consumers beyond those with diabetes started using CGMs to monitor effects on blood sugar and aid in weight loss. The ADA’s updated SOC is an example of a major medical organization taking cues from everyday consumers to drive practical solutions for diabetes prevention and management.
Automated Insulin Delivery Systems
For people who use insulin, automated insulin delivery (AID) systems represent a major advancement. For 2026, the ADA made a major change: Automated Insulin Delivery (AID) is now the preferred way to take insulin (over non-automated insulin pumps and multiple daily injections) for many people with diabetes. These systems use CGM data to automatically adjust insulin delivery, reducing the burden of constant diabetes management decisions.
Automated insulin delivery systems are now preferred for people with type 1 diabetes and many with type 2 diabetes using insulin, without requirements for C-peptide or antibody status. This expanded access means more people can benefit from this technology that can significantly improve blood sugar control while reducing the risk of dangerous low blood sugar episodes.
Diabetes Management Apps
Numerous smartphone apps can help you track blood sugar, food intake, physical activity, medications, and other aspects of diabetes management. Many apps can sync with glucose meters, CGMs, fitness trackers, and other devices to provide a comprehensive view of your health data. Some apps offer features like carbohydrate counting databases, medication reminders, and the ability to share data with your healthcare team.
While technology can be incredibly helpful, remember that it’s a tool to support—not replace—the fundamental lifestyle habits that form the foundation of good diabetes management. The most sophisticated device won’t help if you’re not also paying attention to your diet, staying active, managing stress, and getting adequate sleep.
Building Your Support System
Managing diabetes is a marathon, not a sprint, and having a strong support system can make all the difference in your long-term success. Diabetes management can feel overwhelming at times, and you don’t have to do it alone.
Your Healthcare Team
Your healthcare team is your primary source of medical guidance and support. This team may include:
- Primary care physician or endocrinologist
- Certified diabetes care and education specialist
- Registered dietitian nutritionist
- Pharmacist
- Eye doctor (ophthalmologist or optometrist)
- Podiatrist (foot doctor)
- Mental health professional
- Exercise physiologist or physical therapist
Don’t hesitate to ask questions and advocate for yourself. If something isn’t working or you don’t understand part of your treatment plan, speak up. Your healthcare team is there to help you, but they need your input to provide the best care.
Family and Friends
Educating your family and close friends about diabetes helps them understand what you’re dealing with and how they can support you. They can encourage healthy habits, help you stay accountable to your goals, and provide emotional support during challenging times. If you use insulin or medications that can cause low blood sugar, make sure the people you spend time with know how to recognize and treat hypoglycemia.
Peer Support
Connecting with others who have diabetes can be incredibly valuable. They understand the daily challenges in a way that others might not. Look for local diabetes support groups, or join online communities where you can share experiences, ask questions, and learn from others. Many people find that helping others with diabetes is also beneficial for their own management and motivation.
Practical Tips for Long-Term Success
Managing diabetes does not require a complete lifestyle overhaul. Instead, focusing on simple, consistent habits, like adding more color to your plate, staying active, and choosing balanced meals, can make a meaningful difference over time. Here are some practical strategies to help you maintain healthy habits for the long haul:
Start Small and Build Gradually
Trying to change everything at once is overwhelming and usually unsustainable. Instead, choose one or two changes to focus on initially. Once those become habits, add another change. Small, consistent improvements add up to significant results over time.
Plan Ahead
Planning is key to success with both diet and exercise. Meal planning and prep can help you make healthier choices even when you’re busy or tired. Similarly, scheduling exercise like any other important appointment makes you more likely to follow through. Keep healthy snacks available at home, work, and in your car so you’re not tempted by less healthy options when hunger strikes.
Practice Self-Compassion
Nobody manages their diabetes perfectly all the time. You’ll have days when your blood sugar is higher than you’d like, when you skip exercise, or when you make food choices you later regret. That’s normal and human. What matters is how you respond. Instead of beating yourself up or giving up, acknowledge what happened, learn from it if possible, and get back on track with your next meal or the next day. Self-criticism rarely motivates positive change, but self-compassion does.
Celebrate Your Successes
Acknowledge and celebrate your achievements, no matter how small they might seem. Did you choose water instead of soda? Take a walk after dinner? Check your blood sugar consistently for a week? These victories deserve recognition. Celebrating progress helps maintain motivation and reinforces positive behaviors.
Stay Informed
Diabetes management recommendations evolve as new research emerges. The 2026 ADA Standards of Care emphasize earlier, broader, and more comprehensive diabetes care. Stay informed about new developments by maintaining regular contact with your healthcare team, attending diabetes education programs, and following reputable sources of diabetes information. However, be cautious about information from unreliable sources, and always discuss significant changes to your management plan with your healthcare provider.
Be Flexible and Adaptable
What works for you now might need adjustment over time. Your body changes, your life circumstances change, and diabetes itself can change. Be willing to adapt your strategies as needed. If something isn’t working, don’t be afraid to try a different approach. There’s no single “right” way to manage diabetes—the best approach is the one that works for you and that you can sustain long-term.
Creating Your Personalized Action Plan
Now that you understand the key components of blood sugar management, it’s time to create your personalized action plan. The 2026 update focuses on personalized, patient-centered care and integrating advanced technologies to improve diabetes management and health outcomes. Work with your healthcare team to develop a plan that fits your individual needs, preferences, and circumstances.
Your action plan should include:
- Specific blood sugar targets: Know your target ranges for fasting, pre-meal, and post-meal blood sugar, as well as your A1C goal
- Monitoring schedule: Determine how often you’ll check your blood sugar and what times of day
- Meal planning strategy: Choose an approach that works for you, whether it’s the plate method, carbohydrate counting, following a specific eating pattern like Mediterranean diet, or another approach
- Physical activity goals: Set realistic, specific goals for both aerobic exercise and strength training
- Medication schedule: If applicable, clearly understand when and how to take all medications
- Stress management techniques: Identify specific strategies you’ll use to manage stress
- Sleep goals: Set a target bedtime and wake time to ensure adequate sleep
- Support resources: Identify who you can turn to for support and what resources are available to you
- Regular check-ups: Schedule all necessary appointments and screenings
- Sick day plan: Have a clear plan for managing blood sugar during illness
Write down your plan and review it regularly. Share it with your healthcare team and support system. Update it as needed based on your progress and changing circumstances.
Conclusion: Taking Control of Your Health
Adjusting your lifestyle to keep blood sugar in check requires commitment and effort, but the rewards are substantial. Better blood sugar control means more energy, fewer symptoms, reduced risk of complications, and improved quality of life. While the journey may seem daunting at first, remember that you don’t have to make all these changes at once or achieve perfection.
Focus on progress, not perfection. Each healthy choice you make—whether it’s choosing a vegetable-rich meal, taking a walk after dinner, checking your blood sugar, or getting a good night’s sleep—is a step toward better health. These small steps accumulate over time into significant improvements in your blood sugar control and overall well-being.
The most important thing is to start. Choose one area to focus on today. Maybe it’s adding more vegetables to your meals, taking a 10-minute walk after lunch, or establishing a consistent bedtime routine. Whatever you choose, commit to it for a few weeks until it becomes a habit, then add another healthy change.
Remember that managing blood sugar is a lifelong journey, not a destination. There will be ups and downs, successes and setbacks. What matters is that you keep moving forward, learning from your experiences, and working with your healthcare team to optimize your management plan. With the right knowledge, tools, support, and commitment, you can successfully manage your blood sugar and live a full, healthy, active life.
