Calories in Chicken Breast (Cooked, Raw, Per 100g)

Calories in chicken breast, cooked portions

Cooked, skinless chicken breast has about 165 calories per 100g with ~31g of protein and almost no carbs (USDA FoodData Central). That protein-to-calorie ratio is why chicken breast is the default protein source for anyone tracking macros — it delivers a lot of the muscle-protecting, hunger-killing macro for very few calories.

Cooked vs raw — log the right one

This is the classic chicken tracking error. Raw breast is ~120 cal/100g; cooked is ~165 because cooking drives off water and concentrates the meat. A 200g raw breast becomes ~150g cooked — same calories, different weight. Weigh it in the state you’ll log it, and don’t mix the two.

Why it’s a tracking staple

At ~31g protein per 165 calories, chicken breast makes hitting a protein target (1.6-2.2 g/kg, Morton et al. 2018) easy without crowding your calorie budget. Skin and oil are where the calories climb — a tablespoon of cooking oil adds ~120 calories, often more than the chicken’s own fat.

Set your protein target with the protein calculator and balance the rest with the macro calculator. And since the cooked-vs-raw weight gap fools so many people, photographing the finished plate to estimate the portion sidesteps the error entirely.

Frequently asked questions

How many calories in a chicken breast?
A typical cooked, skinless chicken breast (about 170g) has roughly 280 calories and 53g of protein. Per 100g, cooked skinless breast is about 165 calories (USDA FoodData Central).
How much protein is in chicken breast?
About 31g of protein per 100g of cooked skinless breast — one of the highest protein-to-calorie ratios of any whole food, which is why it's a staple for muscle preservation and satiety.
Why does cooked chicken have more calories than raw per 100g?
Cooking removes water, concentrating the meat. Raw breast is ~120 cal per 100g; cooked is ~165 because the same protein is packed into less weight. Weigh chicken in the same state (cooked or raw) you'll log it in.
