The Keto Diet and Type 2 Diabetes

Diet is important for both Type 1 and Type 2 diabetes.

In a person with diabetes, insulin is either absent or does not work properly. This disrupts the body’s ability to use carbohydrates effectively, causing sugars to be high in the blood. As a result eating a high-carb meal can lead to a spike in blood glucose, especially in a person with diabetes.

As limiting the intake of central carbohydrates is the central concept of the keto diet, it may be a great option for those with diabetes. 

Research has suggested that following a ketogenic diet may:

  • reduce the risk for those susceptible to diabetes
  • improve glycaemic control in people with diabetes
  • help people to lose excess weight


How it works

The premise of a keto diet restricts carbohydrates, which helps to keep blood glucose at a low but healthy level, this encourages the body to break down fats for energy.

The process of using fat for energy is called ketosis, it produces a fuel source called ketones.

The diet helps to lower the body’s demand for insulin which has benefits for people with type 1 and type 2 diabetes, including people on insulin requiring smaller doses of insulin, leading to less risk of large dosing errors.

As the diet helps the body to burn fat, it has advantages for those looking to lose weight, including those with prediabetes or at risk of type 2 diabetes.

High-Fat Foods

The ketogenic diet doesn’t mean you should load up on saturated fats. Heart-healthy fats are key to sustaining overall health. Healthy fats commonly eaten on the keto diet include, eggs, fish, avocado, nuts and olive oil.

Keto Diet and Diabetes research

The keto diet was initially created in the 1920’s as a treatment for epilepsy, through the years there has been numerous studies surrounding the benefits of the keto diet on a variety of health conditions.

In 2008, researchers conducted a 24-week study to test the hypotheses that a low carb diet would lead to greater improvement in glycaemic control in patients with obesity and type 2 diabetes. The study concluded that participants who followed the keto diet saw greater improvements in glycaemic control and medication reduction compared to those who followed a low-glycaemic diet.

In 2013, a review of the therapeutic uses of low carb diets was conducted. The review reported that a keto diet can lead to significant improvements in blood sugar control, weight loss, A1c and discontinued insulin requirements that other diets.

In 2017, a study found that the keto diet outperformed a conventional, low-fat diabetes diet over 32 weeks regarding weight loss and A1c.

Studies from 2018 have found that keto diets can be helpful in controlling levels of HbA1c. This refers to the amount of glucose traveling with haemoglobin in the blood over about 3 months. 

A low carb diet may offer hope to people with type 2 diabetes who have difficulty controlling their symptoms. Not only by reducing diabetic symptoms, but also reducing dependency on medications.
