Calories in Chicken Breast: A Complete Breakdown

Chicken breast is one of the most popular lean protein sources, and its calorie content depends heavily on whether it's cooked with the skin on, and how it's prepared.

Calories per 100 grams

A 100-gram serving of skinless, boneless, cooked chicken breast contains approximately 165 calories and about 31 grams of protein, with roughly 3.6 grams of fat and no carbohydrates.

How cooking method changes calories

Grilled or baked chicken breast without added fat stays close to the base number above. Pan-frying in oil or butter can add 50-100+ calories per serving depending on how much fat is absorbed. Breading and deep-frying can roughly double the calorie count.

Why chicken breast is popular for weight management

Its high protein-to-calorie ratio makes it easy to hit protein targets without a large calorie cost, which is useful whether you're trying to lose fat or maintain muscle.

Chicken breast vs. other cuts

Chicken thigh contains more calories and fat per 100 grams (roughly 209 calories and 11g fat) than breast, but also more flavor and moisture thanks to its higher fat content. Neither cut is inherently 'better' — thigh can fit a higher-calorie or higher-fat goal, while breast suits a leaner, higher-protein target.

Fitting chicken breast into your calorie target

A single 150g cooked chicken breast (roughly 250 calories, 47g protein) pairs well with a cup of rice and a serving of vegetables to build a balanced, protein-forward meal without pushing calories too high.
