Helpful or Harmful? Keto and Diabetes


Keto and Diabetes: Helpful or Harmful?

Diabetes is a chronic metabolic disorder that affects millions of people worldwide. It is characterized by high levels of blood glucose due to the body’s inability to produce or properly use insulin. The keto diet has gained popularity as a potential way to manage diabetes, but is it helpful or harmful? Let’s explore.

What is the Keto Diet?

The keto diet, also known as the ketogenic diet, is a high-fat, low-carbohydrate diet that aims to induce a state of ketosis in the body. This means that the body starts to burn fat for energy instead of glucose. The diet typically consists of 70-80% fat, 10-20% protein, and 5-10% carbohydrates.

How Does the Keto Diet Affect Diabetes?

The keto diet has been shown to improve blood glucose control and insulin sensitivity in people with diabetes. By reducing carbohydrate intake, the body’s need for insulin is reduced, and blood sugar levels are stabilized. Additionally, the diet can lead to weight loss, which is beneficial for those with diabetes as obesity is a risk factor for the disease.

Are there Risks to the Keto Diet?

The keto diet is not without risks. The diet is high in saturated fats, which can increase the risk of heart disease. Additionally, the diet can lead to nutritional deficiencies, as it restricts certain types of foods. It is important to consult a healthcare professional before starting the diet, especially if you have underlying health conditions.

Is the Keto Diet Sustainable?

One of the biggest challenges of the keto diet is its sustainability. The diet is restrictive and can be difficult to follow long-term. Additionally, the body may adapt to the diet over time, leading to a plateau in weight loss and blood sugar control.

What are the Alternatives?

There are other dietary approaches that can be effective for managing diabetes, such as a low-carbohydrate diet or a Mediterranean-style diet. These diets are less restrictive and may be easier to follow long-term.


The keto diet can be a helpful tool for managing diabetes, but it is not suitable for everyone. It is important to weigh the potential benefits against the risks and to consult a healthcare professional before starting any new diet. There are alternative approaches that can be just as effective and more sustainable in the long-term. Ultimately, the best diet for diabetes is one that is individualized and tailored to each person’s needs and preferences.
