Calories in Chicken Breast: Raw vs Cooked, Grilled, Fried and More

Cooked skinless chicken breast has about 165 calories and 31 g of protein per 100 g (3.5 oz); raw, it has about 120 calories and 22.5 g of protein. A typical boneless breast of about 200 g raw (≈ 145 g cooked) comes to roughly 240 calories and 45 g of protein. The gap between raw and cooked is water, not calories, so the most important thing when logging chicken is to match a raw weight with a raw entry and a cooked weight with a cooked one.

Chicken breast calories: the quick chart

The figures below are approximate USDA FoodData Central values for chicken breast. "Cooked" means roasted or baked with nothing added. Birds and cooking times vary a little, so treat these as good working numbers.

Chicken breast (per 100 g / 3.5 oz)CaloriesProteinFat
Skinless, raw≈ 120≈ 22.5 g≈ 2.6 g
Skinless, cooked (roasted)≈ 165≈ 31 g≈ 3.6 g
Skin-on, raw≈ 172≈ 21 g≈ 9.3 g
Skin-on, cooked (roasted)≈ 197≈ 30 g≈ 7.8 g

Plain chicken breast has no carbohydrate, fiber or sugar. Almost all its calories come from protein, which is why it shows up in so many high protein meal plans.

A handy rule of thumb: cooked skinless breast is about 1.65 kcal and 0.31 g of protein per gram. Raw is about 1.2 kcal and 0.225 g of protein per gram. If you want to check a specific entry, the USDA's FoodData Central database lists raw and cooked versions for most cuts.

Calories in one chicken breast, by size

"One chicken breast" is a slippery unit. Supermarket breasts range from about 150 g to well over 300 g raw, and size matters far more than cooking method. Three common sizes, boneless and skinless:

Boneless, skinless breastRaw weightCooked weight (approx.)CaloriesProtein
Small≈ 150 g (5.3 oz)≈ 110 g≈ 180≈ 34 g
Medium≈ 200 g (7 oz)≈ 145 g≈ 240≈ 45 g
Large≈ 280 g (10 oz)≈ 205 g≈ 336≈ 63 g

Notice that the calories and protein are the same whether you work them out from the raw weight or the cooked weight. A medium breast is about 240 kcal raw (200 g × 1.2) and about 240 kcal cooked (145 g × 1.65). Cooking moves water out; it does not burn calories off.

Raw vs cooked chicken: the logging trap

Raw chicken breast is about three-quarters water. As it cooks, it loses roughly 25–30% of its weight, mostly as water and a little fat. The calories stay in the meat, so the same breast simply weighs less and has more calories per gram. That is why the raw entry says about 120 kcal per 100 g and the cooked entry says about 165.

The trouble starts when the weight and the database entry do not match. It is the same mistake people make with rice, which we cover in our guide to calories in rice, but it runs the other way in size: chicken shrinks when it cooks, while rice swells.

Worked example

You buy a 200 g raw breast. After grilling, it weighs about 145 g.

One mismatched breast is not a disaster. But chicken is often eaten daily, and a steady error of 60–90 kcal and 12–17 g of protein quietly skews a food diary, especially a protein target. It is one of the most common calorie counting mistakes we see.

Tip: Cooking a tray of chicken for the week? Weigh it raw and note the calories (raw grams × 1.2). Weigh it again after cooking. Divide the raw calories by the cooked weight to get a per-gram figure for that batch, then weigh each portion you eat. For example, 1,000 g raw (≈ 1,200 kcal) that cooks down to 720 g works out to about 167 kcal per 100 g cooked.

Package labels in many countries give values for the raw meat, so a barcode scan usually gives you raw numbers. Our guide to scanning food barcodes for calories explains how to check which one you are getting.

Skin-on vs skinless chicken breast

Chicken skin is mostly fat. Roasted breast with skin is about 197 kcal per 100 g, compared with about 165 for skinless. On a medium breast (≈ 145 g cooked), that is roughly 50 extra calories, or about 285 kcal in total instead of 240.

Protein barely changes: about 30 g per 100 g with skin versus 31 g without. If you eat the skin, log the skin-on entry. If you peel it off after cooking, the skinless entry is close enough.

Good to know: Bone-in breasts weigh more than the meat you eat. If you weigh a bone-in breast, either use an entry that says "with bone" or weigh the meat after you take it off the bone. The bone and cartilage can be 10–20% of the weight.

Grilled, baked, poached, fried and air-fried

For plain chicken, the method changes the per-100 g number mainly through water: poached chicken holds more of it, a long roast dries it out. The breast's own calories stay about the same. What moves the total is the oil, breading and sauce.

Skinless breast, cooked asPer 100 g cooked (approx.)Medium breast, 200 g raw (approx.)What changes it
Poached or boiled≈ 151≈ 240Holds more water, so fewer kcal per gram
Grilled, no oil≈ 151–165≈ 240How long it cooks
Baked or roasted, no oil≈ 165≈ 240Nothing added
Grilled or baked with 1 tsp olive oil≈ 190≈ 280The oil (≈ 40 kcal per tsp)
Air-fried with a light oil spray≈ 165–170≈ 245–250How much spray
Pan-fried, no coating≈ 185–200≈ 270–300How much oil clings to the meat
Breaded, baked or air-fried≈ 200≈ 380Breadcrumbs and egg wash
Flour-coated and fried≈ 220≈ 400Coating plus absorbed oil
Batter-dipped or deep-fried≈ 260≈ 450–500Thick coating that soaks up oil

You may see grilled chicken breast listed at about 151 kcal per 100 g and roasted at about 165. That difference comes from separate reference samples in the database, not from grilling removing calories. For everyday tracking, either is fine.

Fried and breaded chicken

Breading adds roughly 100–150 kcal to a medium breast, and frying adds more. (The USDA's coated, fried entries include the skin.) A schnitzel, katsu cutlet, chicken parmesan or crispy chicken sandwich sits around 380–500 kcal for the chicken alone, before sauce, cheese or bun. If you ate it at a restaurant, our guide to tracking calories when eating out has tips for estimating the hidden fat.

Marinades and sauces

Dry rubs add almost nothing. A lemon-herb marinade with a tablespoon of oil for four breasts adds about 30 kcal each, while a sweet teriyaki or barbecue glaze can add 50–100 kcal per breast. Tikka paste, yogurt marinades and pesto count too if they are more than a light coating.

How much protein is in chicken breast?

Cooked skinless chicken breast has about 31 g of protein per 100 g, and a medium breast about 45 g. Raw, it has about 22.5 g per 100 g. It is a complete protein, supplying all the essential amino acids.

Per calorie, skinless breast gives about 19 g of protein per 100 kcal. For comparison, whole eggs give about 8–9 g per 100 kcal (see our guide to calories in eggs). Many people aim for roughly 20–30 g of protein at a meal, which is about 65–100 g of cooked chicken breast. Half a medium breast is often enough for a salad, wrap or bowl.

Chicken breast vs thigh, drumstick, wings and deli chicken

Breast is the leanest cut, but the others are not far behind without the skin, and thighs are juicier and more forgiving to cook. Approximate USDA values per 100 g, roasted, meat without bone:

Cut (roasted, per 100 g)CaloriesProteinFat
Breast, skinless≈ 165≈ 31 g≈ 3.6 g
Breast, with skin≈ 197≈ 30 g≈ 7.8 g
Drumstick, skinless≈ 172≈ 28 g≈ 5.7 g
Drumstick, with skin≈ 216≈ 27 g≈ 11 g
Thigh, skinless≈ 209≈ 26 g≈ 11 g
Thigh, with skin≈ 229≈ 23 g≈ 15 g
Wing, with skin≈ 290≈ 27 g≈ 19.5 g

A single roasted wing (about 34 g of meat and skin without the bone) is about 100 kcal before sauce. Fried wings tossed in buffalo, honey-garlic or Korean-style glaze can be 120–160 kcal each.

Rotisserie chicken

Store-bought rotisserie chicken is roasted, so the breast meat is close to the table above: about 150–170 kcal per 100 g without the skin and about 190–210 with it. Dark meat with skin is higher, similar to roasted thigh. Brining adds sodium rather than calories. If the store lists nutrition, use it; otherwise log roasted chicken, skin-on or skinless to match what you ate.

Deli chicken

Sliced deli chicken breast is usually lower in calories per 100 g than home-cooked breast, about 80–110 kcal and 15–20 g of protein, because it is cooked with added water. Two ounces (56 g) is roughly 45–60 kcal and 9–11 g of protein. Products vary, so scan the barcode or read the label.

No cut is better or worse. Thighs give a little less protein and a little more fat, which can be exactly what a stew or curry wants. Log the version you actually ate.

How to log chicken breast quickly

  1. Decide raw or cooked, and stick with it. Raw is most consistent; cooked is fine with a cooked entry.
  2. Pick skin-on or skinless to match what you ate.
  3. Log the fat separately: the teaspoon of oil in the pan, the butter on top, the breading.
  4. Add the sauce or marinade if it is more than a light rub.
  5. Batch-cooked? Use the raw-to-cooked method from the tip above.

Thymi can take care of most of this. Type or dictate "150 g grilled chicken breast with 1 tsp olive oil", scan the barcode on a pack, or take a photo of your plate, and it matches each item to USDA FoodData Central and shows whether the match is Verified or Estimated. If you weighed it raw, say so, and if the portion looks off, "Fix it" lets you correct it in plain words, like "it was 200 g raw, not cooked". If chicken is part of a bigger dish, our guide to counting calories in homemade food walks through logging the whole pot.

Frequently asked questions

How many calories are in 100 g of cooked chicken breast?

Cooked skinless chicken breast has about 165 calories, 31 g of protein and 3.6 g of fat per 100 g, based on USDA data for roasted breast. With the skin on, it is about 197 calories per 100 g.

How many calories are in one chicken breast?

A medium boneless, skinless breast of about 200 g raw (about 145 g cooked) has roughly 240 calories and 45 g of protein. A small 150 g breast is about 180 calories and a large 280 g breast about 336 calories.

Is chicken breast higher in calories cooked or raw?

Per 100 g, cooked chicken breast is higher (about 165 calories versus 120 raw) because it loses roughly 25 to 30 percent of its weight as water. The whole breast has about the same calories either way, so match a raw weight with a raw entry and a cooked weight with a cooked entry.

How much protein is in a chicken breast?

Cooked skinless chicken breast has about 31 g of protein per 100 g. A medium breast of about 200 g raw has roughly 45 g of protein, and a 3 oz (85 g) cooked serving about 26 g.

Does grilling or frying change the calories in chicken breast?

Grilling, baking and poaching add almost nothing, so a medium breast stays around 240 calories. Each teaspoon of oil adds about 40 calories, and breading or batter with frying can bring a medium breast to roughly 400 to 500 calories.

How many calories are in chicken thigh compared with breast?

Roasted skinless chicken thigh has about 209 calories and 26 g of protein per 100 g, compared with about 165 calories and 31 g of protein for skinless breast. With skin, thigh is about 229 calories per 100 g.
