About this tool

Daily protein needs are usually expressed as grams per kilogram of body weight, rising with activity: roughly 0.8 to 1.0 for sedentary people, 1.2 to 1.6 for active people, and 1.6 to 2.2 for athletes. Multiply your weight by the range for your level to get a daily gram target. The result is general information only, not medical advice, and people with kidney conditions should follow their clinician's guidance.

Frequently asked questions

Do I need the top of the range?

Not necessarily — the low end suits most people, while the high end fits heavy training or muscle-building phases.

Can I eat all my protein in one meal?

Your body handles spread-out protein better for muscle maintenance, so splitting it across meals is the usual advice.
