Daily protein (g) = bodyweight (kg) × selected g/kg factorThe ISSN position stand describes 1.4–2.0 g/kg/day as sufficient for most exercising individuals. [2] This tool lets you explore that range; the default 1.6 g/kg is a planning choice, not a personalized prescription.
Per-meal figures simply divide the daily total by your selected number of portions. They do not prescribe meal timing or require supplements. This is not a clinical calculator for kidney disease or other conditions requiring individualized intake advice.
