A 100-gram serving of chicken breast contains approximately:
- Raw chicken breast: Around 120–124 calories
- Cooked chicken breast (skinless, boneless, grilled, roasted, or boiled): About 165 calories
The difference in calories between raw and cooked chicken breast is mainly due to water loss during cooking, which concentrates the nutrients and calories in the cooked meat
. For a typical cooked chicken breast weighing around 172 grams, the calorie count is approximately 284 calories, with about 53 grams of protein and 6 grams of fat
. Additional notes:
- Chicken breast without skin has fewer calories than with skin, as the skin adds fat and calories (about 30 more calories per 100 g)
- Cooking methods that add oil, butter, or sauces will increase the calorie content beyond these baseline values
In summary, expect about 165 calories per 100 grams of cooked, skinless, boneless chicken breast. Raw chicken breast is lower in calories per 100 grams due to water content
