Prediabetes, also known as borderline diabetes, is a warning that an individual is at an increased risk of developing type 2 diabetes. This condition is typically diagnosed through a blood test, revealing higher-than-normal blood sugar levels, but not high enough to be classified as type 2 diabetes. While there is no one-size-fits-all diet for prediabetes, dietary changes can play a crucial role in managing and even reversing the condition. This involves adopting a well-balanced diet with an emphasis on whole grains, lean protein, healthy fats, and fibre-rich foods, while reducing the consumption of added sugars and simple carbohydrates. The Mediterranean diet is often recommended as a beneficial framework for managing prediabetes, but individuals may also explore other eating plans like the ketogenic (keto) diet, intermittent fasting, or plant-based diets. Consulting a registered dietitian or nutritionist can help individuals make informed dietary choices based on their specific needs and preferences.

Prediabetes is when blood sugar is higher than normal but not diabetic
Prediabetes is when your blood sugar levels are higher than normal but not high enough to be classified as diabetes. It is a warning that you are at an increased risk of developing type 2 diabetes and, as a result, are more likely to experience heart disease or a stroke. It is estimated that 38% of American adults have prediabetes, and globally, the rate is 6%. That amounts to nearly 300 million people worldwide who are at risk.
Prediabetes is diagnosed through a blood test as, at this stage, you are unlikely to be experiencing any noticeable symptoms. However, certain factors can increase your risk of developing prediabetes, including being over 45 years old, being overweight, having a close relative with type 2 diabetes, leading a sedentary lifestyle, and belonging to a certain ethnic group. If you meet any of these criteria and are concerned, you should consult your doctor for further guidance.
The good news is that prediabetes can be reversed through healthy lifestyle changes, including eating more nutritious foods. The key to managing prediabetes is adopting a well-balanced diet, staying active, and controlling your weight. This involves cutting down on added sugars, swapping simple carbs for complex carbs, incorporating healthy proteins, and increasing your fibre intake. It's important to note that you don't have to eliminate entire food groups or give up the foods you love. Instead, focus on reducing your portion sizes and incorporating more nutritious alternatives.
There is no one-size-fits-all diet for prediabetes, but certain eating plans can provide a beneficial framework. The Mediterranean diet is often recommended for people with prediabetes, as it emphasises whole grains, lean protein, and healthy fats. The ketogenic (keto) diet, intermittent fasting, and the DASH (Dietary Approaches to Stop Hypertension) diet are also options to consider. These diets aim to establish healthier eating habits that are tailored to your lifestyle, taste preferences, and overall health goals.
In addition to dietary changes, increasing your physical activity can significantly lower your risk of developing type 2 diabetes. Research has shown that lifestyle changes resulting in modest weight loss can delay the onset of type 2 diabetes by 34% for four years. This highlights the importance of taking control of your health through a combination of healthy eating habits and regular exercise.

A balanced diet with whole grains, lean protein, and healthy fats is recommended
A balanced diet is key to managing borderline or prediabetes. This means that no food groups need to be eliminated, but portion sizes should be watched. A good rule of thumb is to fill half your plate with non-starchy vegetables, a quarter with whole grains, and the final quarter with lean protein.
Whole grains are an excellent energy source and are recommended in a borderline diabetes diet. They include wholegrain bread, whole-wheat pasta, brown rice, and wild rice. These foods have a low glycaemic index, meaning they affect blood glucose levels more slowly. Whole grains are also a good source of fibre, which keeps your digestive system healthy.
Lean protein is another important component of a balanced diet for borderline diabetes. Good sources include skinless poultry, lower-fat cuts of beef or pork, fish, eggs, and reduced-fat dairy products such as low-fat milk, yoghurt, and cheese. If you follow a plant-based diet, there are plenty of protein-rich options such as beans, hummus, and lentils.
Healthy fats are also recommended in a borderline diabetes diet. These include monounsaturated and polyunsaturated fats found in foods like olive oil, nuts, avocados, and some types of fish. These healthy fats can help lower cholesterol and protect your heart. It's important to limit saturated and trans fats, which can increase the risk of heart disease and stroke.

Avoid foods with high sugar content, opting for low-GI foods instead
If you have borderline diabetes, it's important to be mindful of your diet and make healthy lifestyle changes. This involves cutting down on foods with high sugar content and opting for low-GI alternatives.
Firstly, it's crucial to understand that sugar is not limited to sweet treats like candy, ice cream, or baked goods. Sugar can be hidden in various everyday foods, including savoury items like pasta sauce. Whole foods such as fresh fruits and dairy products also contain natural sugars. However, the primary concern is often added sugars, which are included in packaged and processed foods during manufacturing. These added sugars can enhance flavour, improve texture, or act as preservatives to extend shelf life.
To avoid consuming excessive amounts of sugar, it's essential to read nutrition labels carefully. Ingredients are listed in descending order, so if sugar appears at the top, it indicates a high sugar content. Common terms indicating the presence of sugar include "syrup," "corn syrup," "high-fructose corn syrup," "honey," "molasses," "fructose," and "dextrose." Additionally, ingredients ending with "-ose," such as glucose, fructose, lactose, maltose, dextrose, and sucrose, usually signify the presence of sugar.
Instead of consuming foods with high sugar content, opt for low-GI alternatives. The glycemic index (GI) measures how quickly a food or drink increases your blood sugar (glucose) level. Low-GI foods are slowly digested and absorbed, resulting in a gradual rise in blood sugar and insulin levels. Examples of low-GI foods include most fruits and vegetables, legumes, nuts, and low-fat dairy products. These foods are packed with essential nutrients and can help manage blood sugar levels effectively.
It's important to note that you don't have to completely eliminate sugary foods from your diet. Enjoying them in moderation and following recommended portion sizes is key. You can also reduce portion sizes or find low- or zero-sugar alternatives. Making your own diabetes-friendly versions of treats at home is a creative way to satisfy your sweet tooth while managing your blood sugar.

Incorporate fruits, vegetables, and healthy proteins into your diet
Borderline diabetes, also known as prediabetes, is a condition where your blood sugar levels are higher than normal but haven't yet reached the threshold for a Type 2 diabetes diagnosis. This diagnosis is a warning sign, but the good news is that prediabetes can be reversed through healthy lifestyle changes, including dietary adjustments and increased physical activity.
Fruits, vegetables, and healthy proteins are essential components of a well-balanced diet, which is crucial for managing prediabetes. Here are some tips to incorporate these nutrients into your diet:
Fruits
Fruits are a healthy source of natural sugar and fibre. While all fruits are generally beneficial, it's best to favour lower-sugar fruits like berries and kiwi. Pairing fruits with a protein source, such as nuts, seeds, or yogurt, can help slow the rate of glucose entering your bloodstream. It's also recommended to consume whole fruits instead of fruit juice, as they provide more fibre and less concentrated sugar.
Vegetables
Vegetables are packed with fibre, which slows digestion and glucose absorption. Focus on incorporating a variety of non-starchy vegetables, such as leafy greens, into your meals. These vegetables are filling and satisfying due to their fibre content.
Healthy Proteins
Lean proteins are an essential part of a balanced diet for prediabetes. Examples include chicken, turkey, fish, tofu, eggs, nuts, and seeds. Pairing proteins with fruits or carbohydrates can help regulate glucose absorption. Additionally, opt for low-fat or non-fat dairy products as part of your protein choices.
Remember, there is no one-size-fits-all diet for prediabetes. Gradual behaviour changes and balanced meals that incorporate a variety of nutrient-dense foods are key to managing and reversing prediabetes.

Exercise and weight control are also important factors
Exercise and weight control are crucial factors in managing borderline or prediabetes. While dietary changes are essential, engaging in physical activity and maintaining a healthy weight can significantly reduce the risk of progressing to type 2 diabetes.
The National Institutes of Health's Diabetes Prevention Program Outcome Study found that a combination of healthy eating habits, weight reduction, and increased physical activity can effectively lower the chances of developing type 2 diabetes. This comprehensive approach has been shown to delay the onset of type 2 diabetes by 34% for four years compared to a placebo group.
When it comes to exercise, aim for a mix of aerobic and resistance training. Aerobic exercises, such as walking, jogging, swimming, and cycling, can help improve your body's ability to use insulin and manage blood sugar levels. Resistance or strength training, such as weightlifting or bodyweight exercises, can help build muscle mass, which is essential as muscle plays a vital role in glucose uptake from the bloodstream.
Additionally, focus on maintaining a healthy weight. Excess weight, especially around the waist, can increase insulin resistance, making it harder for your body to regulate blood sugar levels. Modest weight loss can have a significant impact on improving insulin sensitivity and reducing the risk of type 2 diabetes.
Remember, it is always best to consult with your healthcare provider or a registered dietitian nutritionist (RDN) to determine the appropriate exercise routines and weight goals for your specific needs and circumstances. They can provide personalized guidance based on your health status, fitness level, and lifestyle.
