Keto: a superior diet for people with type 2 diabetes


The ketogenic diet, popularly known as the keto diet, has gained significant attention in recent years for its potential health benefits, particularly for individuals with type 2 diabetes. As the prevalence of type 2 diabetes continues to rise globally, exploring effective dietary strategies to manage this condition is crucial. The keto diet, characterized by a high-fat, moderate-protein, and low-carbohydrate intake, offers promising results in improving blood sugar control and promoting overall health. This article delves into the various ways the keto diet can be beneficial for people with type 2 diabetes.

Understanding type 2 diabetes

Type 2 diabetes is a chronic condition affecting how the body metabolizes glucose, its primary source of energy. In individuals with type 2 diabetes, the body either resists the effects of insulin—a hormone that regulates blood sugar—or doesn’t produce enough insulin to maintain normal glucose levels. This leads to elevated blood sugar levels, which can cause serious health complications over time, including heart disease, nerve damage, kidney failure, and vision problems.

The basics of the keto diet

The keto diet involves a drastic reduction in carbohydrate intake and the replacement of carbohydrates with fats. Typically, the macronutrient distribution in a keto diet includes about 70-75% of calories from fat, 20-25% from protein, and only 5-10% from carbohydrates. By significantly lowering carbohydrate intake, the body is induced into a metabolic state called ketosis. In ketosis, the body becomes highly efficient at burning fat for energy and produces ketones from fat in the liver, which serve as an alternative energy source.

How the keto diet helps manage blood sugar levels: One of the primary challenges for individuals with type 2 diabetes is maintaining stable blood sugar levels. The keto diet can help address this issue through several mechanisms:

  1. Reduction in blood sugar spikes: Carbohydrates are the main dietary source of glucose. By limiting carb intake, the keto diet minimizes post-meal blood sugar spikes, helping maintain more consistent blood glucose levels throughout the day.
  2. Improved insulin sensitivity: Insulin resistance is a hallmark of type 2 diabetes. Studies have shown that a low-carbohydrate, high-fat diet can improve insulin sensitivity. This allows the body to use insulin more effectively and lower blood sugar levels.
  3. Reduced glycogen stores: Glycogen is the stored form of glucose in the body. On a high-carb diet, excess glucose is stored as glycogen in the liver and muscles. The keto diet depletes these glycogen stores, reducing the availability of glucose and encouraging the body to utilize fats for energy.

Weight management and type 2 diabetes: Obesity is a significant risk factor for the development and progression of type 2 diabetes. The keto diet is proven effective for weight loss, which can have a profound impact on managing diabetes. Here’s how:

  1. Appetite suppression: High-fat diets like the keto diet can increase satiety and reduce hunger, leading to lower overall calorie intake and subsequent weight loss.
  2. Increased fat burning: In ketosis, the body becomes more efficient at burning fat for energy, which can contribute to significant weight loss over time.
  3. Reduction in visceral fat: The fat stored around internal organs, known as visceral fat, is particularly harmful and linked to insulin resistance. The keto diet has been found to reduce visceral fat more effectively than other diets.

Cardiovascular benefits: People with type 2 diabetes are at a higher risk of developing cardiovascular diseases. The keto diet can offer cardiovascular benefits, which are crucial for individuals with diabetes:

  1. Improved cholesterol levels: The keto diet can increase levels of high-density lipoprotein (HDL) cholesterol, often referred to as “good” cholesterol, and decrease levels of low-density lipoprotein (LDL) cholesterol, or “bad” cholesterol.
  2. Lower triglycerides: Elevated triglycerides are a common problem in individuals with type 2 diabetes and a risk factor for cardiovascular disease. The keto diet has been shown to significantly reduce triglyceride levels.
  3. Reduced blood pressure: Weight loss and improved blood sugar control on the keto diet can lead to lower blood pressure, reducing the risk of heart disease and stroke.

Potential risks and considerations: While the keto diet offers numerous benefits, it is essential to consider potential risks and take necessary precautions:

  1. Nutrient deficiency: The restrictive nature of the keto diet can lead to deficiencies in essential nutrients, including vitamins and minerals. It’s crucial to ensure a balanced intake of nutrient-dense foods and consider supplements if necessary.
  2. Ketoacidosis: Although rare, individuals with type 2 diabetes, particularly those on insulin or certain diabetes medications, should be aware of the risk of ketoacidosis—a dangerous condition where ketone levels become excessively high. Regular monitoring of blood ketone levels can help prevent this complication.
  3. Individual variability: Not everyone responds to the keto diet the same way. It’s important to work with a healthcare professional to tailor the diet to individual needs and monitor its effects on health.

Practical tips for starting the keto diet: For individuals with type 2 diabetes interested in trying the keto diet, here are some practical tips to get started:

  1. Consult with a healthcare professional: Before making any significant dietary changes, it’s crucial to consult with a healthcare provider, especially for those on medication or with other health conditions.
  2. Plan meals carefully: Focus on whole, unprocessed foods such as leafy greens, non-starchy vegetables, nuts, seeds, and healthy fats like avocados and olive oil. Avoid high-carb foods like bread, pasta, sugary snacks, and most fruits.
  3. Stay hydrated: Proper hydration is essential on the keto diet, as the body excretes more water and electrolytes in ketosis.
  4. Monitor blood sugar levels: Regular monitoring of blood glucose levels can help track the diet’s impact and make necessary adjustments.
  5. Be patient: Transitioning to the keto diet can take time, and some individuals may experience “keto flu” symptoms, including fatigue and irritability, as the body adapts to burning fat for fuel.


The keto diet presents a promising dietary approach for individuals with type 2 diabetes, offering benefits like improved blood sugar control, weight loss, and enhanced cardiovascular health. While there are potential risks and individual considerations to keep in mind, many people with type 2 diabetes have found success in managing their condition through this low-carb, high-fat diet. As with any significant lifestyle change, it’s essential to approach the keto diet with careful planning and professional guidance to ensure it meets individual health needs and goals.
