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.
| Amount | Protein | Calories |
|---|---|---|
| 100g raw chicken breast | about 22.5g | about 120 kcal |
| 100g cooked roasted chicken breast | about 31g | about 165 kcal |
| 150g cooked roasted chicken breast | about 46g | about 248 kcal |
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.
