While the benefit of the ketogenic diet in children with drug-resistant epilepsy (DRE) has been known for over a century, only recently have studies been published looking at its use in adolescents and adults with DRE.
Low carb and childhood epilepsy
The ketogenic diet (KD) has been used to treat epilepsy in children since 1921. The original protocol using a high fat, low carbohydrate diet was created at the Mayo Clinic in Rochester, USA (Wilder, 1921), and popularized by the Johns Hopkins Hospital in Baltimore, MD (Freeman et al.,1998). It is now used in the management of drug-resistant childhood epilepsy in all the leading childrens’ hospitals throughout the world.

In December 2006, The Charlie Foundation commissioned a panel comprised of 26 pediatric epileptologists and dietitians from nine countries with particular expertise using the KD. This group was created in order to create a consensus statement regarding the clinical management of the KD. Subsequently endorsed by the Practice Committee of the Child Neurology Society, this resultant manuscript addresses issues such as patient selection, pre-KD counseling and evaluation, specific dietary therapy selection, implementation, supplementation, follow-up management, adverse event monitoring, and eventual KD discontinuation.

This study was subsequently updated in 2018.

Goswami and Sharma wrote in 2019 “Ketogenic diet (KD) is a time-tested therapeutic modality for refractory epilepsy, which has re-emerged as a robust alternative to anti-epileptic pharmacotherapy. There is a growing body of evidence which supports the anti-seizure efficacy, safety profile and feasibility of KD use in childhood epilepsy.”
Two meta-analyses were published in 2020. Soubron et al concluded that “Despite the heterogeneity between all studies, the beneficial results underline that dietary interventions should be considered for children and adolescents with refractory epilepsy who are not eligible for epilepsy surgery.” Lyons et al concluded that “Ketogenic diet therapy is an effective treatment option for infants with drug-resistant epilepsy.”
