Chicken breast protein: raw vs cooked nutrition

Chicken breast is a lean protein staple, but raw and cooked weights are not the same. Cooking removes water, so 100g cooked chicken is more protein-dense than 100g raw chicken.

Quick answer

100g cooked roasted chicken breast has about 31g protein.

If the user weighs chicken before cooking, use the raw entry. If they log cooked chicken on the plate, use the cooked entry.

How Fit Crate uses this

The app should avoid mixing raw and cooked entries in the same calculation. If a user meal-preps raw chicken and then divides cooked portions, Fit Crate should ask whether the logged weight is raw or cooked before finalizing calories.
