Modified Atkins Diet Plus KetoCal for Adult Epilepsy

  Purpose

The modified Atkins diet (MAD) has been shown to be effective in treating children and adults with medically resistant seizures. A recent study in children showed that the use of KetoCal® once per day in addition to the MAD appeared to be beneficial when used during the first month. The investigators hypothesize that including a daily KetoCal® liquid tetrapak with one meal during the initial month of the MAD will produce urinary ketosis in more adult patients than the MAD alone and will lead to greater seizure reduction.

Further study details as provided by Johns Hopkins University:

Primary Outcome Measures:
  • Ketosis [ Time Frame: 1 month ] [ Designated as safety issue: No ]
    Time to urinary ketosis in days will be recorded and whether or not patients achieve serum ketosis at 1 month and 2 months.


Secondary Outcome Measures:
  • Seizure reduction [ Time Frame: 2 months ] [ Designated as safety issue: No ]
    The percent seizure reduction compared to baseline (1 month before beginning the diet) will be recorded at 1 month and 2 months.

  • Tolerability and taste [ Time Frame: 2 months ] [ Designated as safety issue: No ]
    Patients will be asked to rank convenience, taste, texture, and tolerability of the liquid on a 10 point scale (1 = poor, 10 = excellent).

  • Side effects [ Time Frame: 2 months ] [ Designated as safety issue: Yes ]
    Patients will be screened for constipation and asked if they have experienced any side effects related to use of the modified Atkins diet and KetoCal® at 1 and 2 months.

  • Study completion rate [ Time Frame: 2 months ] [ Designated as safety issue: No ]

Estimated Enrollment: 80
Study Start Date: March 2013
Estimated Study Completion Date: March 2016
Estimated Primary Completion Date: March 2016 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Modified Atkins diet plus KetoCal
Patients will receive the modified Atkins diet in combination with a KetoCal tetrapak daily for the first month. The second month, no tetrapaks will be given.
Dietary Supplement: Modified Atkins diet
Patients will receive the modified Atkins diet with a 20 gram per day carbohydrate limit and encouragement to consume plenty of fat and eat to satiety.
Dietary Supplement: KetoCal
Patients will receive a KetoCal 4:1 ratio (fat: carbohydrates and protein) liquid daily for the first month (if randomized to this arm of the study). They will also be started on the modified Atkins diet.
Other Names:
  • KetoCal 4:1 liquid
  • KetoCal tetrapak
Active Comparator: Modified Atkins diet
Patients will receive the modified Atkins diet for the first month. The second month, they will be given the choice to also use KetoCal in addition to the modified Atkins diet if they choose to do so.
Dietary Supplement: Modified Atkins diet
Patients will receive the modified Atkins diet with a 20 gram per day carbohydrate limit and encouragement to consume plenty of fat and eat to satiety.
