Formula
Daily protein in grams equals body weight in kilograms multiplied by a factor from 0.8 for sedentary up to 2.0 for heavy training.
How it works
Pick the factor that matches training, multiply by body weight, and the result is a daily gram target. Split it across meals rather than eating it all at once.
FAQs

Does it change with a diet?
People losing weight often use the higher end to help keep muscle.
What foods count?
Meat, fish, eggs, dairy, beans, lentils, tofu and similar protein foods.
