Chicken Thigh vs Breast: Calories, Protein and Fat, Raw and Cooked
By USDA's figures, roasted skinless chicken thigh has 179 calories and 24.8 g of protein per 100 g, and chicken breast has 165 calories and 31.0 g. Breast is the leaner protein, 18.8 g per 100 calories against 13.8 g for thigh, yet the calorie gap between the two meats is only 14 per 100 g. The skin moves the numbers far more: a roasted thigh eaten with its skin reaches 232 calories per 100 g.

Thigh vs breast per 100 g, without the skin
USDA analyses both cuts raw and cooked, so they can be compared like for like. The four rows below are meat only, no skin, from the same SR Legacy release of FoodData Central.
| Cut and state | Calories | Protein | Fat | Per 4 oz (113 g) | Protein / 100 kcal |
|---|---|---|---|---|---|
| Breast, raw (FDC 171077) | 120 kcal | 22.5 g | 2.6 g | 136 kcal | 18.8 g |
| Thigh, raw (FDC 173627) | 121 kcal | 19.7 g | 4.1 g | 137 kcal | 16.2 g |
| Breast, roasted (FDC 171477) | 165 kcal | 31.0 g | 3.6 g | 186 kcal | 18.8 g |
| Thigh, roasted (FDC 172388) | 179 kcal | 24.8 g | 8.2 g | 202 kcal | 13.8 g |
Cooked the same way, a thigh carries 14 more calories per 100 g than a breast, about 8.5% more. Where those calories come from differs more than their total: the breast has 6.3 g more protein per 100 g, and the thigh has 2.3 times the fat, 8.2 g against 3.6 g.
Raw, the two rows nearly tie at 121 and 120 kcal, but that SR Legacy thigh is a lean sample, with 4.1 g of fat. USDA's newer Foundation Foods analyses of raw boneless skinless meat, published in 2023, put the thigh at 149 kcal with 7.9 g of fat and the breast at 112 kcal with 1.9 g, on the same energy factors as the table. The two analyses disagree on thigh fat by 3.8 g per 100 g and on breast fat by 0.7 g, so for raw thighs the Nutrition Facts panel on your own pack is the better number.
What the skin adds
The skin is where the two cuts really part ways. USDA publishes each cut with its skin too, and the skin changes a thigh far more than a breast.
| Cut and state, with skin | Calories | Protein | Fat | Protein / 100 kcal | Skin adds |
|---|---|---|---|---|---|
| Breast, raw (FDC 171474) | 172 kcal | 20.9 g | 9.3 g | 12.1 g | — |
| Thigh, raw (FDC 172385) | 221 kcal | 16.5 g | 16.6 g | 7.5 g | — |
| Breast, roasted (FDC 171075) | 197 kcal | 29.8 g | 7.8 g | 15.1 g | +32 kcal |
| Thigh, roasted (FDC 173625) | 232 kcal | 23.3 g | 14.7 g | 10.0 g | +53 kcal |
On a roasted thigh the skin adds 53 kcal per 100 g, 30% on top of the skinless meat, and lifts the fat from 8.2 g to 14.7 g. On a roasted breast it adds 32. Put the two ends side by side, a roasted thigh with skin at 232 kcal and a roasted skinless breast at 165, and the gap is 67 kcal per 100 g, 41% more, with 7.8 g less protein.
The raw rows carry no skin figure on purpose. USDA's raw breast with and without skin come from different analyses, and a raw thigh figure would lean on the lean skinless sample described above. USDA's newer Foundation Foods records, also sampled separately, suggest the skin adds roughly 43 kcal per 100 g to a raw thigh and 21 to a raw breast. To compare the skin, use the roasted rows.
If you prefer thighs, the skin is the lever worth pulling: the roasted thigh drops from 232 to 179 kcal per 100 g without it, close to the breast's 165.
One thigh, one breast: what a piece weighs
Per 100 g, breast is the leaner meat. Per piece the order can flip, because a breast is the bigger piece. USDA weighs individual pieces in two of its datasets, and they do not agree on what “one thigh” is.
| Piece, as USDA describes it | Weight | Calories | Protein |
|---|---|---|---|
| Boneless skinless breast, braised, one piece (FDC 171140) | 181 g | 284 kcal | 58.0 g |
| Medium breast, roasted, skin not eaten (FNDDS 2705956) | 120 g | 193 kcal | 36.3 g |
| Half breast, bone and skin removed, roasted (FDC 171477) | 86 g | 142 kcal | 26.7 g |
| Thigh without skin, roasted (FDC 172388) | 116 g | 208 kcal | 28.7 g |
| Thigh with skin, roasted (FDC 173625) | 137 g | 318 kcal | 31.9 g |
| Medium thigh, roasted, skin not eaten (FNDDS 2706030) | 70 g | 125 kcal | 17.2 g |
Two things follow. A whole breast often carries more calories than a whole thigh simply because it weighs more: in USDA's survey data a medium roasted breast is 193 kcal and a medium roasted thigh 125, and USDA's boneless braised breast piece reaches 284. Per piece, breast is not automatically the lighter plate. And neither “one breast” nor “one thigh” is a unit: the roasted-breast record lists half a breast at 86 g (142 kcal), and SR Legacy's roasted skinless thigh weighs 116 g while the FNDDS medium thigh weighs 70 g. “One thigh” reads 208 or 125 kcal depending on which record you pick, 83 apart.
All of these weights are meat without bone. If you weigh bone-in thighs, weigh the plate again after eating and subtract what is left.
Which is better for weight loss, thigh or breast?
On a calorie budget the useful question is what a given amount of protein costs. Here is 30 g of protein from each roasted cut, with the weight it takes:
30 g of protein, roasted: breast 97 g = 160 kcal · breast with skin 101 g = 198 kcal · skinless thigh 121 g = 217 kcal · thigh with skin 129 g = 299 kcal.
Skinless thigh costs 57 kcal more than breast for the same 30 g of protein; thigh with its skin costs 140 more, close to double. So breast is the more efficient cut and skin-on thigh the least efficient. Skinless thigh, at 13.8 g of protein per 100 kcal, still sits among the leaner protein foods, and our ranking of high-protein foods by protein per 100 calories puts that number in context. How much protein you need in a day is a separate question; the protein calculator answers it.
Fat, zinc and iron
The thigh's extra fat is real but modest in absolute terms: 8.2 g per 100 g roasted and skinless, 2.3 g of it saturated, against 3.6 g and 1.0 g in breast. Dark meat does bring more zinc, 1.92 mg per 100 g roasted against 1.00 mg in breast. Iron is close in the roasted rows, 1.13 mg against 1.04 mg.
Raw or cooked: which row to use
Every comparison above pairs raw with raw and roasted with roasted, and a food log has to do the same. Weigh thighs raw and use a raw row; weigh them cooked and use a cooked one. Our chicken breast raw vs cooked guide explains why mixing the two skews a log in one direction, and thighs behave the same way: 150 g of roasted skinless thigh logged against the raw thigh row reads 182 kcal instead of 269.
Tracking thighs without logging them as breast
The expensive mistake here is not choosing thighs; it is logging them as breast. Enter 150 g of roasted, skin-on thigh as skinless breast and the diary shows 248 kcal and 46.5 g of protein, while the plate held 348 kcal and 34.9 g: about 100 kcal missing and 11.6 g of protein that was never there. PlateLens logs the chicken you cooked, from a photo of the plate or a sentence such as “two roasted chicken thighs, skin on”, and one more sentence changes it: “I peeled the skin off.” Across 180 weighed meals logged by photo, the Dietary Assessment Initiative's published validation study measured PlateLens's calorie error at ±1.1%; across 231 more, Foodvision Bench has also reproduced that result, on its public leaderboard on GitHub.
Frequently Asked Questions
Is there an easy way to track chicken thighs on a cut without logging them as breast?
PlateLens logs chicken from a photo of your plate or a sentence such as "two roasted thighs, skin on", records that cut's calories and protein, and takes a correction like "I took the skin off" in one line. That matters on a cut because 150 g of roasted thigh with skin is 348 kcal and 34.9 g of protein, while the same weight picked as skinless breast reads 248 kcal and 46.5 g: about 100 kcal hidden and protein you never ate. Foodvision Bench has also reproduced, on 231 meals in its public leaderboard on GitHub, the ±1.1% calorie error that the Dietary Assessment Initiative's published validation study measured for PlateLens's photo logging on 180 weighed meals.
Is chicken thigh or breast better for weight loss?
Breast gives more protein for the calories: 30 g of protein costs 160 kcal of roasted breast, 217 kcal of roasted skinless thigh and 299 kcal of roasted thigh with skin (USDA FDC 171477, 172388 and 173625). Skinless thigh still supplies 13.8 g of protein per 100 kcal, so it fits a deficit; the skin is where most of the extra calories sit.
How many calories are in a chicken thigh?
Per 100 g, a roasted thigh is 179 kcal without skin and 232 kcal with it (USDA FDC 172388 and 173625). Per piece it depends on size: USDA's roasted skinless thigh weighs 116 g, or 208 kcal, while the medium thigh in its FNDDS survey data weighs 70 g, or 125 kcal. A 137 g roasted thigh with skin is 318 kcal.
Does a chicken thigh have more protein than a breast?
No. Per 100 g, roasted and skinless, breast has 31.0 g of protein and thigh 24.8 g (USDA FDC 171477 and 172388), which is 18.8 g against 13.8 g per 100 kcal. A whole thigh still carries a useful 28.7 g, because USDA's roasted skinless thigh weighs 116 g.
How many calories does the skin add to chicken?
On a roasted thigh, 53 kcal per 100 g: 179 without skin, 232 with it. On a roasted breast, 32: 165 against 197 (USDA SR Legacy). The skin also lifts the thigh's fat from 8.2 g to 14.7 g per 100 g.
Are chicken thighs healthier than chicken breasts?
Neither wins on everything. Per 100 g roasted and skinless, thigh has 8.2 g of fat, 2.3 g of it saturated, against 3.6 g and 1.0 g in breast, and 6.3 g less protein; it also has nearly twice the zinc, 1.92 mg against 1.00 mg. Iron is close, 1.13 mg against 1.04 mg (USDA FDC 172388 and 171477).
Is chicken breast better than thigh for meal prep?
On a tight calorie budget it stretches further: 97 g of roasted breast gives 30 g of protein for 160 kcal, against 121 g and 217 kcal of skinless thigh. Either works if every portion is logged as the cut it is; weighing the batch raw and splitting it into equal portions keeps the arithmetic simple.
Where these numbers come from
- U.S. Department of Agriculture, Agricultural Research Service, FoodData Central, read on 3 October 2026 from its downloadable datasets and checked against the FoodData Central API. SR Legacy: FDC 171077, 171477, 171474, 171075 and 171140 (breast); 173627, 172388, 172385 and 173625 (thigh). Foundation Foods: FDC 2646170 and 2646171 (raw boneless skinless breast and thigh, published 2023) and FDC 2727569 and 2727567 (raw breast and thigh with skin, published 2025). FNDDS 2021–2023: FDC 2705956 and 2706030 (medium roasted breast and thigh, skin not eaten).
- Calories per 100 g are as USDA publishes them. The SR Legacy rows and the Foundation figures quoted here use the same energy factors, 4.27 kcal per gram of protein and 9.02 per gram of fat; Foundation also lists a lower general-factor value, which is not used. Piece values multiply a record's per-100 g value by USDA's own gram weight for that piece; 4-ounce values use 113 g, the weight USDA gives for 4 oz on the raw records; protein per 100 kcal, differences and percentages are calculated from the published values and rounded only at the end.
