A PubMed search shows there has been a fair bit of publishing activity since this article was last significantly updated. Here are some of the papers that could be used as sources or make interesting reading for understanding the issues. I've got copies of the papers that are indented and those that are free online. I need to get hold of others.

The following have free full text online:

  • Masino SA, Rho JM. Mechanisms of Ketogenic Diet Action. In: Noebels JL, Avoli M, Rogawski MA, Olsen RW, Delgado-Escueta AV, editors. Jasper's Basic Mechanisms of the Epilepsies [Internet]. 4th edition. Bethesda (MD): National Center for Biotechnology Information (US); 2012. PMID 22787591

This one I'm not keen to use since the background section is partly lifted word-for-word from Wikipedia. Therefore citing it would be a bit circular.
