What is the best diet for insulin resistance management?

In today’s fast-paced world, maintaining a healthy lifestyle is more critical than ever, especially if you’re dealing with insulin resistance (1). Understanding the best diet for insulin resistance and incorporating the right foods into your daily meals can make a significant difference in managing this condition effectively.

What is Insulin Resistance?

Insulin resistance is a metabolic condition where your body’s cells don’t respond effectively to insulin, a hormone produced by the pancreas. Normally, insulin plays a vital role in regulating blood sugar (glucose) levels. It acts like a key that allows glucose to enter your cells, where it’s used for energy. However, in individuals with insulin resistance, this process doesn’t work as efficiently as it should (2).

One of the primary consequences of insulin resistance is elevated blood sugar levels, which can increase the risk of developing type 2 diabetes. Additionally, insulin resistance is associated with a higher risk of heart disease, obesity, and metabolic syndrome (2).

The Role of Diet in Insulin Resistance

Diet plays a key role in managing insulin resistance. By making informed dietary choices, you can improve your body’s response to insulin and therefore have better control over your blood sugar levels.

By focusing on the foods for insulin resistance as outlined below, you can positively influence your insulin sensitivity and overall health. However, it’s essential to remember that individual responses to dietary changes may vary. Consulting with your general practitioner (GP) or Accredited Practising Dietitian (APD) can provide personalised guidance tailored to your specific needs.

The Best Diet for Insulin Resistance

Recommended Fruits and Vegetables for Insulin Resistance:

When it comes to selecting fruits and vegetables to support insulin resistance, it’s important to focus on choices that are low in glycemic index (GI) and high in fibre (3). These foods help stabilise blood sugar levels, which is essential for managing insulin resistance effectively.

  • Berries: Blueberries, strawberries, and raspberries are excellent choices. They are not only low in sugar but also packed with antioxidants that can benefit those with insulin resistance (4).
  • Leafy Greens: Spinach and kale are rich in fibre and essential nutrients. Including them in your diet can help regulate blood sugar levels (5).
  • Cruciferous Vegetables: Broccoli and cauliflower are known for their insulin-regulating properties. They also offer a variety of vitamins and minerals (6).

When incorporating fruits, remember that moderation is key, as even healthy fruits contain natural sugars. Consider pairing fruits with a source of protein or healthy fats to help stabilise blood sugar levels.

Is rice bad for insulin resistance?

Rice, particularly short grain white rice, has a high glycemic index and can cause rapid spikes in blood sugar levels, which may not be ideal for individuals with insulin resistance (7). However, there are healthier alternatives such as basmati rice, brown rice and quinoa, which are lower GI and provide more stable energy levels. It’s essential to choose these alternatives and consume rice in moderation if you have insulin resistance. Always consider portion size also, as this plays a key role in how much glucose we’re consuming.

Lean Proteins and Insulin Resistance

Proteins are an essential part of the best diet for insulin resistance (3). Lean protein sources, such as poultry, fish, tofu, and legumes, can help improve insulin sensitivity. These foods provide a steady source of energy without causing significant spikes in blood sugar levels. Including protein in your meals also helps you feel full and satisfied, reducing the temptation to overindulge in carbohydrates.

Healthy Fats and Their Role

Healthy fats are crucial for overall health and one of the key foods for insulin resistance management (3). Incorporate sources of monounsaturated and polyunsaturated fats, like avocados, nuts, seeds, and olive oil, into your diet. These fats have been associated with improved insulin sensitivity. However, be mindful of portion sizes, as fats are calorie-dense. Balancing fats with other nutrient-rich foods is key.

Fibre-Rich Foods and Insulin Sensitivity

Dietary fibre is your ally in the fight against insulin resistance (3). High-fibre foods, such as whole grains, legumes, vegetables, and fruits (with skin when possible), can slow down the absorption of sugar, preventing sudden spikes in blood glucose levels. Aim to include a variety of fibre-rich foods in your diet to promote better insulin sensitivity.

Monitoring Your Carbohydrate Intake

It’s essential to monitor your carbohydrate intake, but it’s equally crucial to choose the right type of carbohydrates. As discussed with rice, it’s important that we opt for complex carbohydrates like whole grains, quinoa, and sweet potatoes, which provide steady energy and are less likely to cause blood sugar spikes. Reducing your intake of refined carbohydrates, sugary snacks, and sugary beverages can also help manage insulin resistance effectively. Additionally, aim to control portion sizes and spread your carbohydrate intake evenly throughout the day to prevent sharp spikes in blood sugar levels.

Portion Control and Meal Timing

Controlling portion sizes and meal timing can be just as important as food choices. Eating smaller, balanced meals throughout the day can help regulate blood sugar levels. Avoid skipping meals, as this can lead to overeating later in the day. If you’re uncertain about portion sizes or meal timing, consider consulting an APD for personalised guidance.

The Importance of Regular Monitoring

Finally, it’s essential to regularly monitor your blood sugar levels and work closely with healthcare professionals (8). Regular check-ups and blood tests can help track your progress and make necessary adjustments to your diet and treatment plan.


In conclusion, the best diet for insulin resistance is achievable with careful food choices and portion control. Prioritise whole, unprocessed foods, and focus on lean proteins, healthy fats, and high-fibre options. While carbohydrates are an important component of the diet, consider alternatives with a lower glycaemic index. Remember that individual responses to foods vary, so personalised guidance from a healthcare professional is invaluable in crafting the best diet plan for insulin resistance.
