Not your parents' ketogenic diet - Flexibility in 2020.

This is a commentary on the details of the increasing flexibility of the original classic ketogenic diet, a well-known evidence-based treatment option for intractable epilepsy. The variety of ketogenic diet therapies (KDT) have shown similar efficacy to the classic version. Initiation protocols, outpatient diet starts, hospital teaching kitchens, premade ketogenic foods and ways to calculate and administer the diet are readily available for ketogenic professionals and their patients. This approach to a more flexible diet management may help to make KDTs easier in compliance, palatability and reducing the risk of side effects.
