When to use
- Setting a protein goal for an adult; the preset is a starting range, not a prescription.
Pearls and pitfalls
- KDOQI 2020 states the CKD ranges for metabolically stable adults; individualize in catabolic illness.
- ASPEN/SCCM obesity targets use ideal body weight: 2.0 g/kg (BMI 30 to 40) and up to 2.5 g/kg (BMI 40 or more).
- Choose Custom to enter your own low and high g/kg.
Why use
Shows the range, the weight it uses and the source for each preset.
Protein (g/day) = g/kg/day × weight (actual, or ideal body weight where the guideline uses it)
