Special points	The ketogenic diet is a high-fat, low-carbohydrate diet [98, 99] that may mediate direct anticonvulsant effects via ketone bodies and/or glucose restriction [100, 101]. However, compliance is extremely difficult, especially for adults; thus, other low glycemic diets, such as a modified Atkins diet, have recently been explored as adjunctive epilepsy therapies in children and adults [102–106]. The ketogenic diet is contraindicated in patients with cardiovascular or mitochondrial disease.
Complications	Hyperlipidemia (ketogenic diet).
Cost	Inexpensive.
