 The ketogenic diet has been studied in at least 14 rodent animal models of seizures . It is protective in many of these models and has a different protection profile than any known anticonvulsant .

This , together with studies showing its efficacy in patients who have failed to achieve seizure control on half a dozen drugs , suggests a unique mechanism of action .
