This is a prospective study to determine whether the Atkins diet reduces seizures, creates ketosis, and is well tolerated in adults with epilepsy. Approximately 30 patients will be enrolled, expecting 20 to complete the 6-month study. The investigators plan to establish the seizure baseline and type, initiate the Atkins diet, then monitor its administration in terms of seizure reduction, ketosis, and side effects for a 6-month period.
