My colleagues and I appreciate Dr Livingston's concern about our introductory statement regarding the present use of the ketogenic diet. Clearly, what we mean is that the ketogenic diet continues to have its place in the management of seizure disorders that have been resistant to medication. We have no intention of discarding the ketogenic diet in these situations; rather, the focus of our study is to better understand the mechanisms underlying the anticonvulsant properties of fasting and a ketogenic diet. Whether the ketogenic diet is "free of toxicity" is another issue, which cannot be discussed in detail at this point.
