Calculate Your Protein Intake

Building muscle requires a calorie surplus, consistent resistance training, and enough protein to fuel muscle repair — generally 1.6g to 2.2g per kilogram of body weight per day. Spreading protein evenly across 3–4 meals, rather than loading it into one meal, gives your body a steady supply of amino acids for muscle protein synthesis throughout the day.

Quick Reference

  • General health (sedentary): 0.8–1.0 g/kg body weight
  • Weight loss: 1.6–2.2 g/kg to preserve muscle in a deficit
  • Muscle gain: 1.8–2.5 g/kg depending on training experience
  • Athletic performance: 2.0–3.1 g/kg
  • Spread intake across 4–5 meals of 25–40g each for best results
