KDIGO guidelines for AKI/ATN suggests the following dietary measures, although most are supported with limited evidence [25] :

  • Total energy intake of 20–30 kcal/kg/d
  • Avoid restriction of protein intake
  • Administer 0.8–1.0 g/kg/d of protein in noncatabolic AKI patients without need for dialysis and 1.0–1.5 g/kg/d in patients with AKI on renal replacement and up to a maximum of 1.7 g/kg/d in patients on continuous renal replacement therapy (CRRT) and in hypercatabolic patients.
  • Entreral nutrition is preferential than parenteral
