6 Ways to Reduce Insulin Resistance for Better Blood Sugar, According to Dietitians

From eatingwell.com

These lifestyle strategies are small but mighty! 

KEY POINTS

• Eat more fibre-rich foods to help improve insulin sensitivity and support blood sugar balance.
• Engage in regular exercise to help muscles use glucose efficiently and boost insulin sensitivity.
• Prioritise sleep, reduce stress and gradually lose weight to help reverse insulin resistance.

Insulin resistance is an often-overlooked condition that is a precursor to a host of metabolic conditions, especially prediabetes and diabetes.

Centers for Disease Control and Prevention. About Insulin Resistance and Type 2 Diabetes.

The good news is there are ways to protect against and even reverse insulin resistance. That’s important because cells rely on insulin around the clock to effectively use glucose for fuel. Plus, reversing insulin resistance can reduce your long-term risk of many chronic illnesses.

Read on to learn all about insulin resistance, how it impacts your blood sugar levels, and the best ways to naturally prevent it.

1. Eat More Plants

Eating more whole, fibre-rich plant foods like beans, lentils, whole grains, leafy greens, vibrant veggies, nuts and seeds is one of the best things you can do to help your body use insulin more efficiently, says Los Angeles-based dietitian Vandana Sheth, RDN, CDCES, FAND. “These foods offer a powerful combination of fibre, antioxidants and anti-inflammatory compounds which help with blood sugar balance and support insulin function,” says Sheth. 

What makes fibre so special? “Dietary fibre slows down the digestion process,” says Dru Rosales, M.S., RD. “As a result, it helps to control blood sugar and cholesterol levels, both of which lead to improved insulin sensitivity.” 

2. Reduce Saturated Fat 

“Excess dietary fat, particularly saturated fat, breaks down into fatty acids and accumulates in your muscle and liver,” says Lauren Plunkett, RDN, LD, CDCES, a registered dietitian and certified diabetes care and education specialist. “These fatty acids stick together and harden the cell wall, which causes insulin resistance.” That, in turn, prompts glucose to accumulate in the bloodstream, resulting in high blood sugar.

High-saturated-fat foods include red and processed meats, full-fat dairy, cream, butter, desserts, baked goods and fried foods. While you don’t have to avoid these foods entirely, it’s wise to have a goal to limit saturated fat to less than 10% of your daily calories. “Intakes greater than this have been shown to increase LDL cholesterol, which is a risk factor for heart disease and type 2 diabetes,” says Rosales.

3. Move Your Body Daily 

There are several ways physical activity helps with insulin resistance. Working muscles need lots of glucose for fuel. When you exercise, your muscles take up glucose and remove it from the bloodstream, whether insulin is available or not. In addition, exercise makes muscle cells more sensitive to insulin. And it helps you build more muscle tissue overall.

What’s the best exercise? The answer is the type you enjoy and can stick to. Aim for 150 minutes of moderate aerobic activity each week, or bump the intensity up to vigorous and shoot for 75 minutes per week. This might look like brisk walking, swimming, biking or jogging. Plus add two days of resistance exercise and some stretching. 

4. Prioritize Sleep 

“Research has shown that sleeping less than the recommended seven hours per night is associated with insulin resistance,” says Rosales. “In addition, [poor] sleep duration and quality are both considered risk factors for type 2 diabetes.”

If you’re not getting seven hours per night, start by going to bed 15 minutes earlier than usual. Once you get acclimated to that, increase by 15 minutes until you hit your goal.  

5. Be Mindful of Stress 

Not all stress is bad, but too much chronic stress can increase insulin resistance. Why? Chronic exposure to stress encourages your body to produce higher levels of stress hormones like cortisol, which can impair glucose metabolism. If this becomes chronic, it can lead to insulin resistance. And when excess stress impairs sleep, it can throw you into a vicious cycle, making things even worse. 

To reduce stress, start small by incorporating activities you enjoy doing. For example, you may try journaling, deep breathing, walking, art, prayer, meditation, yoga, tai chi or any other mindfulness activities that you find soothing.  

6. Consider Weight Loss 

If you are living with overweight or obesity, losing even a small amount of your body weight can increase your insulin sensitivity and help prevent type 2 diabetes, says Rosales. Weight loss is so powerful that research has found that people at high risk for diabetes may reduce their chances of developing diabetes by 58% after losing 5% to 7% of their body weight.

Of course, weight loss can be difficult, especially if you’ve tried to lose weight before only to gain it back. It can be helpful to think “slow and steady” and understand that plateaus will happen. When they do, consider reaching out to a registered dietitian or certified diabetes educator, who can help you find realistic, lasting lifestyle changes to continue to lose weight and keep it off. 

What Is Insulin Resistance? 

Insulin is a hormone produced by your pancreas that helps move glucose from your blood into your muscles, fat cells and liver for energy. However, sometimes, things like weight gain, genetics or a sedentary lifestyle can cause our cells to undergo changes that impair their ability to use insulin effectively. In response, the pancreas produces even more insulin, leading to a vicious cycle known as insulin resistance. Over time, if this cycle becomes chronic, the insulin-producing cells of the pancreas become overworked and lose function, potentially leading to prediabetes or even diabetes.

The encouraging news is, it is often possible to reverse insulin resistance with the diet and lifestyle changes we’ve shared. If you’re not sure where to start, try the tip you find easiest to manage. Then, once you’ve mastered that, try another. Little by little, these small changes can yield meaningful results.

Our Expert Take

You can naturally prevent or reduce insulin resistance with diet and lifestyle changes. Strategies like eating more fibre and less saturated fat, exercising, getting adequate sleep, reducing stress and losing weight—if indicated—can all help your body use the insulin it makes more efficiently. 

These strategies are so effective that when done consistently, they may even reverse insulin resistance, which can prevent, delay and treat diabetes. And it’s never too late to get started. Stack small, consistent changes one day at a time to stay motivated, and reach out for professional help for support and guidance if you feel stuck.

What Is A1c and Why Is It Important?

From eatingwell.com

KEY POINTS 

• A1c measures average blood sugar over 2-3 months, offering a broader view than single glucose readings.
• Elevated A1c levels can signal prediabetes or diabetes and help track long-term blood sugar trends.
• Small lifestyle changes, like balanced meals and light activity, can help improve A1c.

If you’ve recently had a check-up, your healthcare provider may have ordered an A1c test, and perhaps your results came back a little higher than expected. If you’re wondering what this number actually means, you can think of it as your blood sugar “report card”. Instead of showing what your blood sugar is at one specific moment, it provides a big-picture overview of how your blood sugar has been doing over the past few months. Here’s what you need to know about what A1c measures, why it matters and simple ways to support healthy blood sugar levels.

What Is A1c?

Unlike a fingerstick blood sugar reading, which tells you what’s happening at just one moment in time, your A1c test measures your average blood sugar over the past two to three months. It’s reported as a percentage rather than a single blood sugar reading.

The test works by measuring how much glucose has “stuck” to your red blood cells. Because red blood cells live for about three months, the percentage of sugar attached to them provides a snapshot of your average blood sugar during that timeframe.

“This is why it’s often recommended to wait at least three months to recheck an A1c level,” says Sara Wisehart, M.S., RD, LD, CDCES. “Everyone has some sugar in their bloodstream, but when blood cells have much more sugar than normal attached, they become thicker and stickier—and that’s where long-term health complications arise with chronically elevated A1c levels.”

Why Is It Important?

Healthcare providers commonly use A1c to screen for and diagnose prediabetes and diabetes, as well as to monitor how well a person’s blood sugar is being managed over time. Here’s why it’s such an important number for your health.

It can diagnose diabetes or prediabetes.

One of the primary reasons healthcare providers order an A1c test is to screen for prediabetes and diabetes. Unlike a single blood sugar reading, A1c offers a broad picture of your blood sugar patterns over time, making it a valuable tool for identifying blood sugar levels that have been consistently elevated.

“A1c helps identify prediabetes and diabetes and monitor whether a treatment plan is working,” says Johannah Katz, M.A., RD. “However, it does not reveal individual blood sugar spikes, lows or day-to-day variability.”

Here are the diagnostic criteria for A1c set by the American Diabetes Association1:

• Below 5.7%: Normal
• 5.7% to 6.4%: Prediabetes
• 6.5% or higher: Diabetes

It reflects your long-term blood sugar levels.

One elevated blood sugar reading doesn’t tell the full story. Factors like stress, illness, poor sleep, medications and even eating before a blood test can temporarily affect your blood sugar levels. Because A1c reflects your average blood sugar over the previous two to three months, it provides a more complete picture of your overall blood sugar management rather than a snapshot of one particular day. This makes it especially useful for tracking trends over time and seeing whether lifestyle changes or medications are helping improve your blood sugar overall.

It predicts your risk of other metabolic health conditions.

Consistently elevated blood sugar doesn’t just affect your glucose numbers; it can also impact your long-term health. Over time, high blood sugar can damage blood vessels and nerves throughout the body, which can increase the risk of complications affecting the heart, kidneys, eyes and nervous system. Even modest improvements in A1c can have meaningful health benefits, and monitoring your A1c allows you and your healthcare provider to identify concerns early and make changes that may reduce your risk of future complications before they become more serious.

It’s not drastically impacted by daily fluctuations.

Many people worry that one bigger-than-normal meal or a few higher blood sugar readings have “ruined” their A1c. Thankfully, that’s not how the test works. Because A1c reflects an average over several months, one dessert, one holiday meal or even a stressful or wonky week is not likely to dramatically change your lab results. Remember, your A1c reflects your overall habits and blood sugar patterns over time.

Other Tips for Supporting Healthy Blood Sugar Levels

“Don’t freak out if your blood sugar is high,” says Amy Beney, M.S., RD, CDCES. “There are about 42 factors that affect blood sugar, with stress being one of the biggest. Understand that there are so many treatment options available to help manage blood sugar.”

Here are several tips that can make a meaningful difference:

• Take your medications as prescribed. If a healthcare provider has prescribed you a medication, taking it consistently is one of the most effective ways to improve blood sugar management.
• Cut back on high-sugar drinks. “One of the best ways to reduce added sugar intake is by cutting down on sugar-sweetened beverages,” says Hennis Tung, M.S., RD. Replace soda, sweet tea, sports drinks or juice with plain water or options like fruit-infused water and unsweetened tea. Katz also recommends checking the Nutrition Facts label for added sugars and notes that the American Heart Association recommends limiting added sugar to 25 grams or less per day.

• Pair carbohydrates with protein and fibre. Rather than avoiding carbohydrates altogether, balance them with foods that help slow digestion and support steadier blood sugar levels. “Include an egg or nut butter with whole grain toast, or add chicken or another protein to salads or sandwiches,” suggests Lisa Andrews, M.Ed., RD, LD.
• Move your body after meals. Even a short walk can make a difference. Research has found that breaking up sitting time with brief periods of light walking improves post-meal blood sugar compared with remaining seated. Start with what feels manageable (even five to 10 minutes counts!) and build from there, says Katz.
• Fill half your plate with non-starchy vegetables. “Think salad greens, broccoli, cauliflower, green beans or stir-fry vegetables,” says Wisehart. “The fibre from these foods helps fill you up, supports more stable blood sugar and if you eat these first, you’re often more satisfied with smaller portions of the other foods on your plate.”

Our Expert Take

A1c is a valuable tool for understanding your long-term blood sugar trends. Rather than focusing on a single glucose fingerstick reading, it paints a bigger picture of how your blood sugar has been managed over the last few months. If your number comes back higher than expected, remember that small, sustainable changes to your eating habits, physical activity, sleep, stress management and, when appropriate, medications can all help improve your blood sugar over time.

Endocrinologists Share 5 Habits to Break for Healthier Blood Sugar

From eatingwell.com

Plus, some everyday habits endocrinologists recommend instead 

KEY POINTS

• Frequent dips and spikes in blood sugar can increase risk of prediabetes and type 2 diabetes.
• Endocrinologists shared five habits they wish you'd stop doing for healthier blood sugar levels.
• Focus on eating more fibre, managing stress and exercising regularly to support blood sugar.

After enjoying something sweet, you may notice a quick burst of energy followed by an afternoon slump. That’s because—similar to a roller coaster—blood sugar levels naturally rise and fall throughout the day. While these fluctuations are normal, frequent highs and lows over time aren’t ideal for long-term health, as they can increase the risk of conditions like prediabetes and type 2 diabetes.

As endocrinologist Jennifer Cheng, D.O., explains, “There are millions of undiagnosed, diabetic and prediabetic people in the U.S. There are significant complications when people develop diabetes that can be potentially preventable.”

So, how can we keep blood sugar levels in a healthy range? We asked endocrinologists which habits to stop for healthier blood sugar, and they shared five.

1. Drinking Sugary Drinks

From soda to sports drinks to sweetened coffee, tea, cocktails and mocktails, there are many ways to gulp down sugar—often without realizing just how much is in your go-to beverage. Yet sugar-sweetened beverages are the leading source of added sugar in Americans’ diets.

The issue with these drinks is that, unlike solid foods, they don’t contain fibre, protein or fat, so the sugar is absorbed quickly. “This can lead to sharp rises in blood sugar and insulin levels,” says Sowjanya Naha, M.D. “Research shows that regular intake of sugar-sweetened beverages, and even fruit juice in large amounts, is linked with a higher risk of developing type 2 diabetes.”

Beyond that, these beverages don’t offer much nutritional value. So what’s a better option? Dietitians recommend water, seltzers or sparkling water, or unsweetened flavoured beverages like herbal tea or infused water. 

2. Staying Sedentary All Day

Whether we’re at our desks trying to crank out work before a deadline, in meetings, in the car or on the couch, one habit worth breaking for better blood sugar control is sitting for long periods of time. 

“Sitting for long periods reduces the body’s sensitivity to insulin, making it harder to control blood sugar. Even small increases in daily movement—such as walking more often—can improve how the body regulates glucose,” says Naha.

Physical activity helps the body increase glucose uptake by the muscles, effectively lowering circulating blood sugar even without additional insulin, explains Cheng. A simple strategy: Set an alarm to get up each hour, and make it a habit to move after meals. Research suggests that even a short walk after eating can help lower blood sugar.

“Walking, even for 15 minutes after eating, can help sensitize your body’s response to insulin,” explains Anastasios Manessis, M.D. If you’re glued to your desk or couch throughout the day, try quick bursts of movement like body-weight squats, lunges or jumping jacks for 30-second intervals.

3. Relying on Refined Carbohydrates

A common knee-jerk reaction to improving blood sugar is to cut carbs entirely—but endocrinologists say not so fast. The type and amount of carbohydrates matter most. 

Carbs worth limiting are those low in fibre, such as sugary cereals, baked goods and snack foods like pretzels and chips. Experts say regularly relying on these foods can lead to more significant blood sugar swings. “Research using continuous glucose monitors suggests that diets higher in these types of carbohydrates tend to cause larger swings in blood sugar throughout the day. These ups and downs may place more strain on metabolic health over time,” shares Naha.

So what should you choose instead? “Whole carbs like fruits, vegetables and whole grains are not only good for your blood sugar, but your overall health,” says Manessis. “These nutrients are high in vitamins, minerals and fiber, which can help support heart health, brain health, weight management and so much more.”

And don’t be too quick to cut fruit. “Whole fruit is bound in fibre and nutrients which can support a healthy blood sugar response,” Manessis adds. In fact, research has found that people who consume moderate amounts of whole fruit tend to have better insulin function and a lower risk of diabetes, showing an inverse relationship between fruit intake and diabetes risk.

For a steadier blood sugar response, pair fruit with a source of protein or healthy fat, such as a handful of nuts or seeds, or Greek yogurt or cottage cheese. 

4. Getting Poor Sleep

Another habit worth breaking: not getting enough quality sleep. 

“Poor or inconsistent sleep can raise blood sugar levels and make it harder to maintain control. Research shows that sleep restriction and circadian disruption can impair glucose metabolism and increase insulin resistance,” says Naha.

Lack of sleep may also affect stress hormones because when you’re not getting enough sleep, cortisol levels can rise, explains Cheng. “This causes more insulin resistance and higher sugars in the blood. Chronic high stress or cortisol levels may increase risk of diabetes and high blood pressure, leading to more disease.”

On top of that, poor sleep may leave us reaching for more carb-rich foods throughout the day to keep energy levels up, points out Manessis. Research suggests that even two nights of poor sleep may increase hunger hormones and lower appetite-suppressing hormones.

So how can you improve your sleep? Aim to maintain a consistent sleep and wake schedule, target seven to nine hours of sleep each night and limit caffeine and screen time before bed to support healthier glucose regulation, says Naha.

5. Skipping Meals or Eating at Irregular Times

Keeping consistent meal times and avoiding regularly skipping meals may help support healthy blood sugar levels.  

“Eating at irregular times or late at night can interfere with the body’s natural rhythms for processing glucose. Studies show that when eating is out of sync with these rhythms, the body handles sugar less effectively, leading to higher and more variable blood sugar levels,” says Naha.

Skipping meals may have a similar effect—including skipping breakfast. “Our bodies love consistency and regularity, so starting the day off with a strong, protein-rich breakfast can be helpful to stabilize our blood sugars and set the tone for the day,” explains Manessis. 

Try eating around the same times each day when possible. And if you find yourself consistently skipping meals like breakfast, consider prepping something the night before—such as overnight oats or breakfast burritos—so you always have an easy option ready to go. 

Other Tips for Healthy Blood Sugar Levels

When it comes to maintaining healthy blood sugar levels, endocrinologists shared these additional tips:

• Pair protein and fat with carbohydrates. Pairing carbs with a source of protein or healthy fat may help support healthier blood sugar levels. Try adding nut butter to a waffle, or pair fruit with cottage cheese.
• Eat more fibre. Dietary fibre is essential for slowing the absorption of glucose, which significantly stabilizes sugar levels, says Cheng. Aim to include fiber-rich foods at meals and snacks, such as veggies, fruits, beans, nuts, lentils, seeds and whole grains.
• Manage stress. “Ongoing stress has been associated with greater variability in glucose levels and increased metabolic risk,” says Naha. Incorporating stress-relief practices—whether a few minutes of mindfulness, deep breathing or yoga—may help support overall blood sugar regulation.
• Stay hydrated. “Proper fluid intake assists your kidneys in filtering excess glucose from the bloodstream via urination,” says Cheng. Keep a water bottle nearby or set reminders throughout the day to help make hydration a habit.
• Exercise regularly. Physical activity can improve insulin sensitivity and support healthy blood sugar levels even after exercise. Find movement you enjoy—whether it’s walking, jogging, swimming, cycling, hiking or taking a fitness class—to make consistency easier.

Our Expert Take

For healthier blood sugar levels, endocrinologists recommend moving away from habits like drinking sugary drinks, staying sedentary all day, eating only refined carbs, getting poor sleep and skipping meals. Instead, focus on supportive habits such as pairing protein and fat with carbohydrates, eating more fibre-rich foods, managing stress, staying hydrated and exercising regularly. “Blood sugar control is shaped by patterns over time rather than single decisions. Even small daily habits can have a meaningful impact when practiced consistently,” says Naha.
