Diet composition. The analysis of the diet diaries of the per protocol treated patients. A The patients of the ketogenic diet/fasting group (KD-IF) group met the set goal of 21–23 kcal/kg/d with a mean intake of 18.0 ± 4.1 kcal/kg/d during the first three days and of 16.2 ± 6.6 kcal/kg/d during the second phase of calorie-restricted ketogenic diet. Calorie intake of the SD group was expected to be about 30 kcal/kg/d (German Society of Nutrition, DGE) but had been lower with an intake of 20.6 ± 8.8 kcal/kg/d. B The set carbohydrate restriction of at most 50 g/d could also be achieved by the KD-IF group with an intake of 39.3 ± 21.6 g/d and 38.3 ± 21.0 g/d in the phases of KD. (C upper row) The diet of the SD group matched the macronutrient composition recommended by the (DGE). (C lower row) Classic ketogenic diet without calorie restriction has a ratio of 3 or 4 g of fat to 1 g of protein and/or carbohydrate. Analysis of the days of ketogenic diet showed that a ratio of 2:1 could be achieved
