Experimental
Active Comparator
Keto-diet (KD)
Low Protein Diet group (LPD)
Patients in the intervention arm (KD group) will receive a vegetarian very low protein diet (0.3 g proteins/kg ideal body weight per day) supplemented with ketoanalogues of essential amino acids (Ketosteril®, Fresenius Kabi, Bad Homburg, Germany), 1 capsule for every 5 kg of ideal dry body weight per day.
The patients in the control arm (LPD group) will continue their conventional low protein diet, with 0.6 g/kg per day (including high biological value proteins). The total recommended energy intake is of 30 kcal/kg of ideal dry body weight per day in both arms.
