The ketogenic diet is an extremely effective dietary intervention used in the treatment of epilepsy.1 One of the oldest treatments for epilepsy (in use since the 1920s), the ketonic diet is a customized low-carb, high-fat diet.
In recent years, pediatric neurologists, epileptologist’s, and general neurologists have shown renewed interest in the use of the ketogenic diet for the management of drug-resistant epilepsies, especially among children and adolescents.2
What Is The Ketogenic Diet?
The intake of grains, bread, pasta, and starchy fruits and vegetables is reduced. Instead, the consumption of butter, cream, oils, and other fatty foods is increased. There are different forms of ketogenic diet and you will need the help of an experienced dietitian to guide you through the diet.
The types of foods to be eaten and the way each diet is structured are slightly different. Most of the fat in the classic, most commonly used ketogenic diet is provided as long-chain triglycerides. A variant of the classic ketogenic diet is the medium-chain triglyceride diet. This diet is also considered
Mechanism Of Action Of Ketogenic Diet
Epilepsy is a neurological disorder in which nerve cell activity in the brain becomes disrupted, leading to repeated seizures, unusual sensations, and, sometimes, loss of consciousness.
It can be caused by a variety of conditions, including head trauma, infection, brain tumor, stroke, and some unidentifiable causes as well. The ketogenic diet is believed to trigger biochemical changes which remove seizure-causing short circuits in the signaling system of the brain.
It imitates the metabolism of fasting and relies on a fundamental change in the brain’s metabolism wherein ketone replaces glucose as the source of energy (keto = ketone, genic = producing). Higher levels of ketone are believed to help in seizure control.7
Who Is The Diet Suitable For?
The ketogenic diet may not work for all children, but is suitable for many different seizure types and epilepsy syndromes, including myoclonic
Safety And Efficacy Of Ketogenic Diet
According to research studies, the ketogenic diet is relatively safe for long-term. The efficacy of the diet has been proved by various studies.9
For instance, in a study conducted at Hopkins Children’s Centre, 101 patients aged 2 to 26 years were treated with the ketogenic diet for a minimum of 16 months and for up to eight years (between 1993 and 2008). Their observation showed that nearly 80 percent of the patients remained either seizure-free or had their seizures reduced by half. Most patients’ seizures did not worsen even years after stopping the diet.10
According to other studies, the ketogenic diet has proved to
Ketogenic Diet Side-Effects
The ketogenic diet is highly effective, but it can be complicated and sometimes difficult to maintain. It can have the following side effects:12
- A temporary rise in cholesterol levels.
- Can lead to kidney stones in rare cases.
- Cause digestive problems, such as diarrhea, constipation, nausea, vomiting, and heartburn.
- Reduce energy levels.
- Slow down growth rate in children.
- Trigger vitamin and mineral deficiencies.
The ketogenic diet can be considered as an alternative therapy for children with difficult-to-control seizures. Despite challenges in implementing the treatment, the ketogenic diet has significant potential as a powerful tool for fighting epilepsy.
