Chicken Breast Protein: 100g, 150g & 200g (Raw vs Cooked)

150 g cooked chicken breast provides about 45.8 g protein, while 150 g raw provides about 33.8 g. Select how you weighed it and calculate protein and calories for 100 g, 200 g, ounces, or any custom serving using the matched USDA records.

Quick answer

Chicken breast protein calculator

100 g cooked chicken breast has about 30.5 g protein and 151 calories. The same cooked USDA record gives about 45.8 g protein for 150 g, 61.1 g for 200 g, 76.4 g for 250 g, and 91.6 g for 300 g. Choose raw or cooked to match how you weighed the chicken; the two records are not interchangeable.

How did you weigh it?
Serving amount

Enter the edible chicken weight only. Custom values cover servings such as 350 g, 500 g, or 1 kg; large outputs are calculations, not serving recommendations. Breading, sauce, skin, and cooking oil are not included.

Raw and cooked weights are not interchangeable. Cooking removes water, so protein looks higher per 100 g even though cooking does not create extra protein.

Your result

100 grams cooked chicken breast has 30.5 grams of protein and 151 calories.

Proper Guide and Practical Notes

How much protein is in chicken breast?

Use about 30.5 g protein per 100 g cooked skinless chicken breast as the source-matched planning answer. A 3 oz cooked serving gives about 26 g protein, 4 oz gives 34.6 g, 6 oz gives 52 g, and 8 oz gives 69.3 g. By gram weight, 150 g gives 45.8 g protein, 200 g gives 61.1 g, 250 g gives 76.4 g, and 300 g gives 91.6 g.

Raw vs cooked chicken breast protein

Protein does not disappear during normal cooking, but water loss makes cooked chicken more protein-dense per 100 g. USDA FDC 2646170 lists 22.5 g protein per 100 g raw boneless skinless breast, while FDC 171534 lists 30.54 g per 100 g cooked grilled breast. Match the database entry to whether you weighed raw or cooked chicken.

How many calories are in chicken breast?

Plain cooked grilled skinless chicken breast has 151 kcal per 100 g in USDA FDC 171534. That scales to about 227 kcal for 150 g, 302 kcal for 200 g, 378 kcal for 250 g, and 453 kcal for 300 g. Raw boneless skinless breast is about 112 kcal per 100 g in the selected Foundation record. Oil, skin, breading, marinades, and sauce must be counted separately.

How much protein is in one chicken breast or chicken fillet?

A breast or fillet is not a fixed serving size. The USDA cooked record includes a large 196 g breast, which scales to about 59.9 g protein and 296 kcal, but actual pieces can be much smaller or larger. For an accurate one-breast answer, weigh the edible portion and use the calculator with the matching raw or cooked state.

Grilled, baked, boiled, fried, canned, and packaged chicken are different entries

This page uses plain cooked grilled skinless breast as its cooked benchmark. Plain baked or boiled breast may be close, but fried chicken, skin-on breast, canned chicken, deli slices, pre-cooked strips, and products with retained water or added solution can differ in calories, fat, sodium, and protein per 100 g. Prefer the exact package label or a preparation-matched database record.

Is chicken breast a complete protein?

Yes. Chicken breast is an animal protein and provides all essential amino acids, so it is considered a complete protein. That makes it a reliable anchor for muscle gain, weight loss, and simple meal prep when the rest of the plate supplies fiber, carbohydrates, fats, and micronutrients.

Use the right chicken breast page

Use this page when you need detailed answers for 100 g, 3 oz, 150 g, one cooked breast, raw-vs-cooked tracking, and USDA source context. Use the chicken breast chart page when you want a shorter comparison card inside the full meat protein chart.

Best way to use it for weight loss

Use cooked chicken breast as a 30-50 g protein anchor, then add vegetables, potatoes, rice, or beans depending on your calorie target. Avoid counting breading, sauces, and frying oil as if they were plain chicken.

Best way to use it for muscle gain

For muscle gain, pair 120-200 g cooked chicken breast with enough carbohydrates and calories to support training. Chicken breast is very lean, so rice, potatoes, pasta, olive oil, avocado, or dairy may be needed when the goal is gaining weight rather than simply increasing protein.

Food safety note

USDA FSIS lists poultry at 165 F as the safe minimum internal temperature. Use a food thermometer for thick breasts, stuffed chicken, leftovers, and meal prep batches.

Frequently Asked Questions

How much protein is in 100g chicken breast?

USDA FDC 171534 lists 30.54 g protein per 100 g cooked grilled skinless chicken breast, commonly rounded to 30.5-31 g. USDA FDC 2646170 lists 22.5 g per 100 g raw boneless skinless breast. Use the record matching the state you weighed.

How much protein is in 3 oz and 150g chicken breast?

A 3 oz cooked chicken breast serving has about 26 g protein. A 150 g cooked serving has about 45.8 g protein when scaled from USDA FDC 171534.

How much protein is in 200g, 250g, and 300g chicken breast?

Using the cooked grilled USDA record, 200 g chicken breast has about 61.1 g protein and 302 kcal, 250 g has 76.4 g protein and 378 kcal, and 300 g has 91.6 g protein and 453 kcal. These are cooked edible weights.

How much protein and how many calories are in 4 oz, 6 oz, and 8 oz chicken breast?

Four ounces of cooked grilled chicken breast has about 34.6 g protein and 171 kcal; 6 oz has about 52 g protein and 257 kcal; and 8 oz has about 69.3 g protein and 342 kcal. Ounce-to-gram conversions and nutrition are rounded.

How many calories are in 100g raw versus cooked chicken breast?

The selected USDA cooked grilled record has 151 kcal per 100 g, while the selected raw boneless skinless record has about 112 kcal per 100 g. Water loss during cooking changes the concentration, so use the entry matching when the chicken was weighed.

How much protein is in one chicken breast?

A large cooked chicken breast listed at 196 g provides about 59.9 g protein when scaled from USDA FDC 171534. Smaller grocery-store pieces can be much lower, so weighing the cooked portion is more accurate.

Can I calculate 500g, 1 lb, or 1 kg of chicken breast?

Yes. Enter the edible weight in the calculator. From the cooked grilled record, 500 g calculates to about 152.7 g protein and 755 kcal, 1 lb cooked to about 138.5 g protein and 685 kcal, and 1 kg cooked to about 305.4 g protein and 1,510 kcal. These are mathematical totals, not serving recommendations, and raw package weight is not the same as cooked edible weight.

Is cooked chicken breast good for weight loss?

Yes, plain cooked skinless chicken breast is useful for weight loss because it gives high protein for relatively few calories. The final meal still depends on added oil, breading, sauces, rice, wraps, and side dishes.

Is chicken breast better than protein powder?

Chicken breast is usually better as a whole-food meal anchor because it provides complete protein and satiety. Protein powder is more convenient when you need protein quickly or cannot eat another full meal.
