The ketogenic diet (KD) is a special diet with high-fat, low-carbohydrate and moderate amount of protein. The KD therapy is a safe, potentially effective and important treatment of refractory childhood epilepsy in recent years. It has confirmed clinical efficacy and a generally good prognosis.

In this paper, the effective rate, patient compliance, adverse reactions and their causes of KD in treating children with refractory epilepsy were reviewed.
