Exactly how much protein do I need?

Protein needs are usually based on body weight, and most people who do not have a wound need to eat about 1g of protein for every kg that they weigh, every day.

However, to heal a large wound the body usually requires 1¼-1½ times more protein than usual.

To work out how much protein is needed to heal a large wound, weight in kilograms is multiplied by 1.25 or 1.5 For example, a person who weighed 40kg and had a large wound would need to consume 50-60g protein every day to help heal their wound.
