An effective medical replacement therapy: ketogenic diet for intractable childhood epilepsy

Abstract

Ketogenic diet (KD) a high fat, adequate protein and low carbohydrate restrictive diet has a long history of its use in intractable epilepsy of childhood. The diet produces biochemical changes mimicking that of starvation. The high levels of ketone bodies produced by KD act as a major source of energy for brain replacing the usual glucose. Comprising the ratio of 4:1 (fat:carbohydrate and protein) by weight, the diet produces state of ketonemia or ketosis that leads to reduction in frequency of epileptic seizures by is unique mode of action. To increase the palatability medium chain triglycerides (as coconut oil) in ratio of 3:1 is used which is more efficiently absorbed and have lesser gastro intestinal side effects as compared to traditional 4:1 ratio diet with long chain triglycerides like PUFA.
