Protein Requirement Calculator For CKD/Liver Disease

Estimates use kg and g/kg guidelines by © 2025 by Dr Lakdhesz. Not a prescription — seek clinician advice if you have medical conditions.

Age (years)

Body weight (kg)

Height (optional, cm)

Primary goal Maintenance / General health Build muscle (strength training) Reduce body fat (in calorie deficit) Bulking / maximize muscle + surplus Kidney function (eGFR ml/min/1.73m²) On dialysis / end-stage kidney disease (check if yes) Known liver disease (cirrhosis, hepatic encephalopathy, etc.)

Quick notes:

• RDA for healthy sedentary adults ≈ 0.8 g/kg/day (baseline).

• For muscle-building most evidence supports ~1.6 g/kg/day (range ~1.2–2.2 g/kg depending on intensity/age).

• In CKD, protein intake often needs individualization; advanced CKD may require lower targets or specialist advice. Dialysis patients typically need higher protein intake due to losses.

Main guideline sources for logic: JISSN/consensus on protein for athletes and hypertrophy; KDIGO/KDOQI and KDOQI nutrition guidance for CKD; ESPEN/ACG guidance for liver disease. (See below for citations.)
