Over the past century, the efficacy of dietary thera-pies for intractable seizures has increasingly been
recognized. Currently there are four main types of
metabolic therapy in use for the reduction of seizures.
Three of these have a high fat content and low car-bohydrate content—the classic ketogenic diet, the
medium chain triglyceride (MCT) diet and the modi-fied Atkins diet (MAD)—and the fourth controls the
carbohydrate quality, the low glycemic index treat-ment (LGIT). These treatments are usually consid-ered in patients with intractable epilepsy who have
failed to respond to several AEDs and are not suitable
candidates for surgery
