How the estimate works
Generally healthy older adults use 1.0–1.2 g/kg/day. The illness or recovery illustration uses 1.2–1.5 g/kg/day and needs individual adjustment for condition, activity, tolerance, and clinical goals. The per-meal line simply divides the calculated range by three; it is not a separate recommendation.
Kidney disease or a prescribed diet: seek individual advice from your clinician or registered dietitian before changing protein intake.
