How this estimate is calculated

Daily grams = body weight in kg × selected multiplier. Per-meal grams divide the daily total into four meals. The adult RDA is 0.8 g/kg; higher targets are optional planning scenarios, not a universal requirement.

Protein needs depend on activity, health and body composition. If you have kidney disease or a prescribed protein restriction, use your clinician's target.
