Choose the factor through individual assessment. Kidney disease, pregnancy, childhood and other clinical circumstances need specific guidance. Equal meal portions are a planning option, not a requirement.
Turn your assessment into a client plan
Set client nutrition targets, build meal plans and keep consultation notes together in Notrispace.

Daily protein (g) = body weight (kg) × your chosen factor (g/kg/day). Per-meal protein = daily protein ÷ number of meals. This is arithmetic, not a recommendation of a protein factor.
Worked example
At 70 kg and a practitioner-selected factor of 1.2 g/kg/day, the result is 84 g daily, or 28 g across three equal meals. The example factor is not a prescription.
