Calculate Your Protein Intake

Wound repair is a protein-intensive process: the body needs amino acids to form new tissue, blood vessels and immune cells. Falling short slows healing and raises the risk of complications, which is why protein needs rise during recovery from surgery or injury.

Prioritise protein at every meal and consider protein-rich snacks if appetite is low, since illness and injury often reduce intake at the very time needs are highest. This is general guidance, so follow the advice of your medical team for serious wounds.

  • Healing target: about 1.25-1.5 g/kg per day
  • Large or serious wounds may need more
  • Protein builds tissue and supports immunity
  • General guidance; follow your medical team's advice

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
