Ketogenic food pyramid for patients with refractory epilepsy: From theory to clinical practice

Objective To develop a graphical representation in the form of a food pyramid for a ketogenic diet for dietary treatment in children and adolescents with refractory epilepsy. Methods The pyramid was constructed based on: the estimation of energy requirements for different age groups, macronutrient distribution, food groups, and the number of servings and respective amounts of food according to the ketogenic diet. Serving sizes were based on the calculation of energy and macronutrient requirements according to age and nutritional status. Results The pyramid was divided into three tiers and 5 food groups (fats, proteins, type 1 vegetables, type 2 vegetables, and fruits). Four portion size lists were defined for the following age groups: 1-3 years, 4-6 years, 7-10 years, and 11-19 years. Conclusion The ketogenic diet food pyramid can be used as nutritional guidance for patients undergoing this dietary therapy by illustrating the variety of foods that can be eaten during the treatment, optimizing adherence to the treatment, and guaranteeing beneficial effects on seizure control.
