How much protein do you need?

Protein needs are usually expressed per kilogram of body weight and depend on your goal:

  • Fat loss — 1.6–2.2 g/kg to preserve muscle while cutting calories.
  • Maintenance — 1.2–1.6 g/kg to support general health and recovery.
  • Muscle gain — 1.6–2.4 g/kg to fuel muscle growth.

The midpoint of each range is a good daily target for most people. Spread it across your meals for best absorption.
