This article will discuss steps to prevent or reverse prediabetes and improve overall health.

Who Is at Risk for Prediabetes?

Around 1 out of every 3 adults has prediabetes. Because there are usually no clear symptoms of prediabetes, many people with the condition do not know they have it.

While researchers don’t fully understand what causes prediabetes (high blood sugar levels that are not yet high enough to be considered diabetes), it generally develops in people who already have insulin resistance. Insulin resistance occurs when your cells stop responding to insulin and your body can’t produce enough insulin to keep up.

Prediabetes is more common in individuals who:

Are overweight Have a parent or sibling with diabetes Live a sedentary (inactive) lifestyle Have an imbalanced diet Have health conditions such as high cholesterol, high blood pressure (hypertension), or sleep apnea Have a history of heart disease or stroke Are 45 years or older Have polycystic ovary syndrome (PCOS) (a hormone condition affecting people assigned female at birth) Have a history of gestational diabetes (diabetes during pregnancy) Have metabolic syndrome (a group of conditions that increase your risk of developing heart disease, stroke, and type 2 diabetes)

If you are at risk for prediabetes, you can prevent or delay its onset by eating healthy, engaging in regular physical activity, and maintaining a healthy weight.

Eat a Healthy Diet

A diet low in nutrients, high in sodium, sugar, and unhealthy fats (processed food) increases your risk of prediabetes. A diet high in red meat can also increase your risk.

Improving the quality of your diet by consuming a variety of whole, unprocessed foods can help keep your blood sugar levels within a healthy range and help you maintain a healthy weight.

Facts About Sugar and Carbs

Carbohydrates are the body’s primary energy source and are a vital part of a healthful diet. Simple and complex carbohydrates are the two main types of carbohydrates in foods.

Simple carbs are sugars that your body breaks down quickly, leading to spikes in blood sugar. While naturally present in some foods (fruit and milk), simple carbs are commonly found in processed and refined sugars, such as candy and table sugar, that lack essential nutrients.

Complex carbs (beans, whole grains, and vegetables) take longer to digest and are less likely to cause blood sugar spikes. They also are higher in nutrients and fiber, which slows down digestion and can help keep you feeling full.

Foods to Eat

A balanced diet is key for preventing or reversing prediabetes. Including more fiber-rich foods, such as beans, peas, lentils, and whole grains, can help improve blood sugar control, protect against chronic disease, help with weight management, and protect your heart.

Protein can help increase feelings of fullness. Additionally, studies show that adding protein to a carb-based meal can help reduce spikes in blood sugar following a meal.

Eating more foods high in healthy fats in place of carbohydrates and saturated fat can help improve blood sugar levels. Foods that are high in protein, fiber, and healthy fats include:

FruitsVegetablesBeans, peas, lentilsLean proteins (fish, chicken, and tofu)Whole grainsNuts, seeds, avocados

Foods to Avoid

Reducing sugary, processed foods can help stabilize your blood sugar and improve overall health, thus reducing your risk of prediabetes. Some foods to limit or avoid include:

CandyFruit juice and other sugary beveragesPastriesPasta from white flourProcessed foods with added sugarWhite bread and white riceBreakfast cereals

Achieve a Healthy Weight

While your overall health cannot be measured by your body weight alone, achieving and maintaining a healthy weight can help prevent and control prediabetes and other chronic health conditions.

What Is a Healthy Weight?

For adults, a “healthy weight” is a number that is associated with a lower risk of health issues and weight-related diseases. Everyone has a different healthy weight based on their body frame, muscle mass, age, gender, and genetics.

How Weight Affects Diabetes Risk

Excess weight can increase your risk for type 2 diabetes, heart disease, and stroke. It can also increase your risk for other prediabetes factors, including high blood pressure, high blood sugar, and high cholesterol.

An increased waist circumference is also associated with an increased risk of diabetes. A waist circumference larger than 35 inches in people assigned female at birth or 40 inches in those assigned male at birth indicates excessive abdominal fat, which increases your risk of developing certain conditions, such as diabetes.

Exercise Every Day

Regular physical activity reduces your risk of type 2 diabetes, heart disease, stroke, and high blood pressure. It can also improve your mental health and help you achieve and maintain a healthy weight.

Exercise can drastically reduce insulin resistance, a hallmark of prediabetes. This means your body will absorb sugar from your blood more effectively, reducing the amount of insulin needed.

Most adults should aim to get at least 30 minutes of moderate-intensity physical activity five days per week. Examples of moderate-intensity exercise include:

Brisk walkingBikingLight yard workWeight-liftingDancingHiking

If you’re new to exercising, begin with light-intensity exercise and gradually build up to moderate intensity.

Treat Sleep Apnea

Sleep apnea, a sleep disorder that happens when your breathing stops and restarts many times while you sleep, is associated with obesity, prediabetes, and insulin resistance.

Symptoms of sleep apnea include:

Loud snoring Gasping for air when you sleep Waking up to a dry mouth or headache Daytime fatigue

Sleep apnea treatment includes lifestyle changes, such as avoiding alcohol and smoking, maintaining a healthy weight, and exercising. Your healthcare provider may also prescribe a continuous positive airway pressure (CPAP) device to keep your airway open while you sleep.

Summary 

While you can’t change some contributing factors to prediabetes, like age or genetics, you can reduce your chance of getting prediabetes or having it progress to type 2 diabetes by making diet and lifestyle changes. These include maintaining a healthy weight, eating a balanced diet, and exercising regularly. It’s also important to receive proper treatment for any health conditions you may have, such as sleep apnea.

A Word From Verywell

If you have been told you have prediabetes or are at risk for the condition, you may feel overwhelmed. The good news is that with early detection and lifestyle modifications, it can be reversed. Try to stay positive and focus on making slow, gradual diet and lifestyle changes that can last a lifetime.
