OBJECTIVE The ketogenic diet (KD) is a high-fat, adequate-protein, and low-carb diet. Ketone bodies increase in the blood due to low carbohydrate content and high-fat content in the diet. The most important feature of the ketogenic diet is that it causes the production of ketone bodies in the liver. Ketone bodies are an alternative fuel to glucose for the brain and form the structure necessary for the cell membrane and biosynthesis of triglycerides. The ketogenic diet provides evidence on seizure control with anticonvulsant effects. In this review, the positive/negative effects of KD on seizure control, place, importance, quality of life, cognition, and behavior in the treatment of resistant epilepsy were examined. METHODS Scientific information on the subject was obtained from the literature accessed through databases such as MEDLINE, Embase, Web of Science, Cochrane Central, www.ClinicalTrials.gov, PubMed, Science Direct, and Google Scholar. RESULTS Although it has started to be used as a treatment method in many diseases today, the main area of effect of KD is drug-resistant epilepsy. In order for the ketogenic diet to be successful in these patients, it is necessary to choose the appropriate patient, medical treatment and diet plan, inform the patient sufficiently, and perform frequent monitoring in accordance with the follow-up criteria. It is argued that KD is one of the most effective treatments for epilepsy. CONCLUSION The fact that KDs generally have a restricted diet pattern, the need for supplementation, biochemical findings and possible side effects raise the issue of diet sustainability. More clinical studies are needed to generalize.
