                                According to the USDA, a 3.5-ounce (100-gram) serving of cooked, skinless, boneless chicken breast contains approximately 165 calories. For a slightly larger 5-ounce serving, this figure changes due to the loss of water during cooking, concentrating the nutrients and resulting in a calorie count closer to 200.
