Abstract :Objective: The ketogenic diet, which has been used in the treatment of epilepsy since the 1920s, is a diet containing high fat, sufficient protein, and low carbohydrate. The ketogenic diet mimics the metabolic effects of fasting by shifting metabolism towards fat utilization. The ketogenic diet, which has different variants, such as the classical ketogenic diet, modified Atkins diet, and medium-chain triglyceride diet, is used in inborn errors of metabolism to target the underlying metabolic state by bypassing the damaged metabolic pathway or to treat the clinical symptoms of inborn errors of metabolism, such as epileptic seizures. In this review, we assessed the evidence for ketogenic diet interventions in the treatment of inborn errors of metabolism. Methods: The Google Scholar search engine, PubMed, Scopus, and Science Direct databases were used to find studies on the use of ketogenic diet interventions in the treatment of inborn errors of metabolism. Results: The beneficial effects of different variants of the ketogenic diet on glucose transport type 1 deficiency syndrome and pyruvate dehydrogenase complex deficiency have long been recognized. There are also favorable data on its use in myopathic glycogen storage diseases, mitochondrial diseases, and nonketotic hyperglycinemia accompanied by epilepsy. Conclusion: The evidence is mostly based on individual case reports, case series, and clinical trials with small sample sizes and is insufficient to make recommendations.
