Enter your body weight and choose your activity level or goal. The calculator shows a recommended daily protein range in grams for that goal.
General health needs about 0.8 g per kg of body weight, active people 1.2–1.6 g, and those building muscle often aim for 1.6–2.2 g per kg.
Protein targets are usually set per kilogram of body weight because muscle maintenance scales with body mass rather than total calorie intake.
For healthy people, moderately high protein is generally safe, but very high intakes offer little extra benefit. Those with kidney issues should seek medical advice.
