How Many Calories in a Chicken Breast?

A skinless cooked chicken breast has about 165 kcal and 31 g of protein per 100 g.

Chicken breast is one of the leanest, highest-protein foods you can eat, which is why it's a staple for weight loss and muscle building. Here's how calories change between raw and cooked, and with skin.

Why cooked vs raw matters

Chicken loses water when cooked, so a cooked 100 g portion contains more chicken and more calories per gram than raw. Track portions by cooked weight for accuracy.
