Frequently Asked Questions

How many calories are in a chicken breast?
A medium cooked skinless chicken breast (about 150g) contains roughly 248 calories and 47g of protein. Per 100g cooked, chicken breast provides 165 calories. The exact count depends on the size of the breast and whether any oil or sauces are added during cooking.
How much protein is in 100g of chicken breast?
100g of cooked skinless chicken breast provides approximately 31g of protein — making it one of the most protein-dense whole foods available. Raw chicken breast delivers around 22.5g per 100g; the higher cooked figure reflects water loss during cooking, not added protein.
Is chicken breast good for weight loss?
Yes. Chicken breast is low in calories relative to its protein content, which promotes satiety and helps preserve muscle mass during a calorie deficit. Its high thermic effect means your body burns 20–35% of the calories in protein just through digestion and metabolism.
Does cooking method change the calories in chicken breast?
Cooking method alone does not change the calorie count. Grilled, baked, boiled, and steamed chicken breast all deliver equivalent calories when no fat is added. Adding oil, butter, or sauces significantly raises the total.
