The fat is located primarily under the skin of the chicken and around the internal organs. Everyone who keeps diet aiming at losing weight or cleaning the body from fats shall remove the skin.
I recommend that before you start cooking, carefully remove the skin with a sharp knife and discard it. Calories in 100 grams of chicken are: boiled chicken - 125 kcal., roasted chicken - 144 kcal., chicken legs - 120 kcal., skinless chicken breasts - 109 kcal. Select a menu suitable for your diet.
