Good to know

  • Raw and cooked weights are different. 100 g of raw skinless breast has 120 calories and 22.5 g of protein. Cooking removes water, so the same piece weighs less and has more calories per gram. Match the entry to when you weighed the chicken.
  • This entry is meat only. Skin, breading, marinades and sauces add calories.
  • Half a roasted breast (86 g) has about 142 calories and 26.7 g of protein.
