 The ketone bodies are possibly anticonvulsant in themselves ; in animal models , acetoacetate and acetone protect against seizures . The ketogenic diet results in adaptive changes to brain energy metabolism that increase the energy reserves ; ketone bodies are a more efficient fuel than glucose , and the number of mitochondria is increased . This may help the neurons to remain stable in the face of increased energy demand during a seizure , and may confer a neuroprotective effect .
