Protein Calculator for Older Adults (65+)
The PROT-AGE numbers — why protein needs rise with age exactly when appetite falls, and how to meet them.
Ageing muscle responds less to small protein doses ('anabolic resistance'), so the same stimulus needs ~0.4 g/kg per meal where younger adults manage on 0.24 — roughly 25–30 g per main meal, including breakfast, the meal where older adults most often under-eat protein. Kidney disease changes these numbers: that's a clinician conversation.
