Chauveau et al. [79] found that a VLPD (0.30 of vegetal protein/kg of body weight/day and 5–7 mg of phosphorus/kg of body weight/day), supplemented with essential amino acids and keto-analogues (with an energy intake close to 30 Kcal/kg of body weight/day), for 2 y was safe for 13 stable advanced chronic renal failure patients (8 men; average age of 55 y; mean GFR of 15 mL/min) regarding nutritional status and circulating PTH reduction. Here, PTH is linked to chronic kidney disease.
