Treatment will consist of ketogenic diet. KD will consist of 4:1 [fat] : [protein+carbohydrate] weight ratio with 1600 kcal restriction. The diet will be supplemented with vitamins, calcium, phosphorus, zinc and selenium supplements to meet the requirements of US Dietary Reference Intakes (DRI) standard.
