Calories and protein CKD stages requirement

Stage 1 CKD

There are no protein restrictions unless the patient has diabetes.

Stage 2 CKD

The Academy recommends no protein restriction while filtration is less than 50; the KDOQI recommends beginning protein restriction when the rate is less than 70.

Stage 3 to 4 CKD

The Academy recommends protein intake of 0.6 to 0.8 g/kg; the KDOQI recommends 0.6 to 0.75 g/kg.

There is strong evidence to support maintaining recommendations for protein intake of roughly 0.7 g/kg to prevent malnutrition and kidney disease progression. Patients with diabetes should not be given a protein intake below 0.8 to 0.9 g/kg, as 0.7 g/kg can result in hypoalbuminemia.7

Stage 5 CKD (dialysis)

Hemodialysis patients should have a protein intake of 1.1 to 1.2 g/kg

Peritoneal dialysis patients should have a protein intake of 1.2 to 1.3 g/kg, which can go as high as 1.5 g/kg because of losses caused by dialysis changes.

All protein should be 50% to 75% high biological value, or the proportion of absorbed protein in food.
