Enter weight, activity level, goal, age and meals: the tool multiplies weight (kg) by 0.8–1.8 g/kg to give daily and per-meal protein. Example: 65 kg, moderate activity, weight-loss → 91 g/day. Adult RDA is 0.8 g/kg (USDA Dietary Guidelines 2020).
Use your weight, activity level and goal to find the exact grams of protein you need each day. Example: a 70-kg very-active lifter aiming to gain muscle needs about 140 g protein—double the adult RDA of 0.8 g/kg (National Academies, 2005).
