Daily Protein Intake Calculator
Estimates daily protein needs based on body weight and goal. Higher intake ranges are used in muscle-preservation and active-aging contexts — always discuss goals with a clinician.
How this is calculated
Formula: Protein (g/day) = body weight (kg) × goal factor.
Goal factors are drawn from ISSN, ACSM, and geriatrics literature. Chronic kidney disease may warrant lower intakes — never override medical guidance.
