ketogenic diet in children

The ketogenic diet (keto), a high-fat, very low-carbohydrate eating plan, has gained widespread popularity in recent years. While adults may explore it for various reasons, the question of its safety and effectiveness for children often arises. This article delves into the complexities surrounding the keto diet and its potential implications for children, aiming to provide a balanced and informative perspective.

Understanding the Keto Diet

The keto diet drastically reduces carbohydrate intake, aiming for as low as 50 grams or even less per day, depending on individual factors. This significant reduction shifts the body’s primary fuel source from glucose (derived from carbohydrates) to ketones, produced through the breakdown of stored fat in the liver. This metabolic state, called ketosis, is believed to contribute to weight loss, improved blood sugar control, and potential benefits for specific neurological conditions in adults.

In a shorter and simpler term, a ketogenic diet is a low-carb and a high-fat diet. The science behind this is that carb rich diet leads to a high glucose levels in blood which can not be sustained in the body over a long period of time, unlike fat rich diet which takes longer to digest and glucose is released into the body at balanced levels over a long period of time.

Potential Benefits for Children

While research on the long-term effects of keto in children is limited, it has been used under strict medical supervision for specific medical conditions, including:

  • Intractable childhood epilepsy: This form of epilepsy is unresponsive to conventional medications. Studies have shown that the keto diet can be effective in reducing seizures in approximately half of children with this condition [1].
  • Certain metabolic disorders: In specific cases, such as pyruvate dehydrogenase deficiency, the keto diet can offer therapeutic benefits [2]. In this condition, the mainstay treatment is the intake of a low carbohydrate diet, which is the case with a Ketogenic diet.

Important Note: It is crucial to understand that these applications are strictly monitored and managed by healthcare professionals and should not be undertaken by parents or children independently. So do not in any circumstance, use any of the mentioned tips without consulting with a trained and registered medical professional.

Potential Concerns and Risks for Children

Despite potential benefits in specific medical contexts, there are significant concerns and risks associated with the ketogenic diet in children:

  • Nutritional deficiencies: A strict ketogenic diet can limit the intake of essential nutrients found in fruits, vegetables, and whole grains, potentially leading to deficiencies in vitamins, minerals, and fibre. These deficiencies can have detrimental consequences for a child’s growth and development. Therefore it is important to seek advice from a licensed dietician and your doctor if you want it for your child.
  • Impaired growth and development: Children are in a critical period of growth and development, requiring a balanced diet with all essential nutrients. The restrictive nature of the ketogenic diet could potentially hinder their growth and development if not carefully managed by qualified healthcare professionals.
  • Social and psychological implications: Restricting access to certain food groups can create social challenges and potentially contribute to negative relationships with food. Additionally, the complexity of managing such a restrictive diet can lead to anxiety and stress in children. Remember that children are still growing, and restricting essential minerals can be disruptive to their growth progress.
  • Uncertain long-term effects: The long-term effects of the keto diet on a child’s developing body and health are largely unknown. Research in this area is ongoing, and further studies are needed to establish the safety and efficacy of the ketogenic diet for children in the long term.

Alternatives to the Keto Diet for Children

For children struggling with weight management or other health concerns, evidence-based and medically approved approaches should be prioritized. These approaches often involve:

  • Balanced and healthy eating: Encouraging children to adopt healthy eating habits that emphasize whole foods, fruits, vegetables, whole grains, and lean protein sources is crucial for proper growth and development. Avoid giving junk food and sugary foods to your child, which might lead to conditions such as obesity, predisposing them to more serious conditions.
  • Portion control and physical activity: Promoting appropriate portion control and encouraging regular physical activity are key components of a healthy lifestyle for children of all ages. Encourage your child to participate in sports activities at their school. This does not only help them physically but also mentally allowing them to socialize with other children.
  • Consulting a healthcare professional: Collaborating with a registered dietitian or paediatrician is essential to develop a safe and personalized approach to address any specific health concerns a child may have, ensuring their individual needs are met. I always encourage patients to take their children for regular check-ups so that any problems can be detected and solved as early as possible.


The ketogenic diet is not generally recommended for children outside specific medical contexts under strict medical supervision. The potential risks associated with nutritional deficiencies, impaired growth and development, and unknown long-term effects outweigh any potential benefits for most children. Emphasizing a balanced and healthy diet, appropriate portion control, and physical activity remains the cornerstone of promoting good health and well-being in children.

Consulting a healthcare professional is always crucial to determine the best approach for each child’s unique needs and ensure healthy growth and development.
