Ketogenic diet: outpatient initiation, without fluid, or caloric restrictions.
Although the ketogenic diet has been used for more than 80 years, the optimal methods of initiating the diet and its maintenance have not been clearly defined. This retrospective study was performed to review our experience with initiation of the ketogenic diet in the outpatient and inpatient settings and maintenance of the diet without fluid or caloric restriction. We analyzed 54 patients who had medically intractable epilepsy of whom 44% manifested some degree of mental retardation, 80% had multiple seizure types, and failed on average 4.8 antiepileptic drugs. Forty-four patients underwent induction of the ketogenic diet on an outpatient basis and 21 as inpatients. Three patients in each group were fasted at the initiation of the diet. No significant differences were observed with regard to seizure control in that 62% and 71% had greater than 50% improvement in the outpatient and inpatient groups, respectively. Both groups manifested improvement in alertness and social interaction. The efficacy of a ketogenic diet in the symptomatic epilepsies was confirmed, and benefit for medically refractory childhood absence epilepsy was documented. We conclude that a prospective, randomized trial is necessary to compare outpatient vs inpatient initiation of the ketogenic diet and the utility of fluid and caloric restriction.
