The ketogenic diet (KD) is an efficacious treatment for intractable epilepsy, associated with infrequent side effects. The KD is known to be deficient in most vitamins and minerals and may be deficient in trace minerals. We report biochemical selenium deficiency in nine patients on the KD, including one who developed cardiomyopathy.
