# Protein Calculator

Calculate daily protein requirements for your weight and goal. Compares US RDA (0.8 g/kg), EFSA Europe (0.83 g/kg), WHO, and sport nutrition guidelines (1.6–2.2 g/kg).

## Quick answer

Protein needs by goal (per kg body weight): General health: 0.8–1.0 g/kg (US RDA). Fat loss: 1.2–1.6 g/kg. Muscle gain: 1.6–2.2 g/kg (ISSN). Endurance sports: 1.2–1.4 g/kg. For a 75 kg person: that's 60g (maintenance) to 165g (serious muscle building). EFSA (Europe) uses 0.83 g/kg; WHO minimum is 0.66 g/kg.
