Why the 100g Protein Number Changes
When someone searches for protein in chicken per 100g, they usually want a simple number for meal planning, calorie tracking, sports nutrition, or comparing foods. The useful answer is that chicken is protein-rich, but the figure changes with the cut, skin, cooking method, and whether the 100 g is weighed before or after cooking.
Cooking is especially important. Heat drives off water, so the cooked meat weighs less even though most of its protein remains. This concentrates protein into each 100 g of cooked meat. That is why a cooked chicken-breast entry can show roughly 30–31 g of protein per 100 g while a comparable raw entry may be closer to the low-20-gram range.
The most reliable way to track intake is therefore not to chase one universal value. Match your food to a specific nutrition entry: breast or thigh, skinless or skin-on, raw or cooked, and preferably the same preparation method. If you use a packaged product, its nutrition label may be more relevant than a generic database value.
Quick Answer: Protein in Chicken per 100g
A practical estimate for cooked, skinless chicken breast is about 30–31 g of protein per 100 g. Raw skinless breast is typically lower per 100 g because it contains more water. Cooked thigh usually provides somewhat less protein per 100 g than cooked breast because dark meat contains more fat.
Use these as planning ranges, not laboratory constants. Food-composition values vary with the exact cut, trimming, retained moisture, cooking loss, brand, and whether added solutions are present.
If precise tracking matters, weigh the chicken in the same state as the database entry. A cooked weight should be paired with a cooked entry; a raw weight should be paired with a raw entry.
Key Takeaways
- Cooked skinless chicken breast commonly provides about 30–31 g protein per 100 g.
- Raw chicken usually shows less protein per 100 g because it contains more water before cooking.
- Chicken thigh is still protein-rich but generally has more fat and slightly less protein per 100 g than breast.
- Cooking does not create protein; water loss concentrates the protein into a smaller final weight.
- For accurate tracking, match raw weights to raw entries and cooked weights to cooked entries.
- Skin, marinades, injected solutions, breading, and brand formulation can change the numbers.
- USDA food-safety guidance recommends cooking poultry to a safe minimum internal temperature of 165°F (73.9°C).

Methodology and Nutrition Sources
This guide uses standard food-composition principles and authoritative U.S. government food-safety information. Protein values are presented as practical ranges because chicken composition changes with cut, skin, preparation, moisture loss, and database sampling.
For exact food records, use a reputable composition database such as USDA FoodData Central and select the entry that best matches your chicken. For cooking safety, the USDA Food Safety and Inspection Service recommends a minimum internal temperature of 165°F for poultry.
How Much Protein Is in Chicken per 100g?
Chicken breast is usually the most protein-dense common cut, especially when cooked without skin. The table gives useful planning ranges rather than pretending every preparation has one exact value.
| Chicken type | Typical state | Approx. protein per 100 g | Why it differs |
|---|---|---|---|
| Chicken breast, skinless | Cooked | About 30–31 g | Lean cut; cooking removes water and concentrates nutrients |
| Chicken breast, skinless | Raw | About 21–24 g | Higher water content before cooking |
| Chicken thigh, skinless | Cooked | About 25–28 g | More fat than breast; moisture loss varies |
| Chicken drumstick meat | Cooked | About 24–28 g | Dark meat and trimming affect composition |
| Chicken wing meat | Cooked | About 23–30 g | Skin and bone make serving comparisons less straightforward |
For a nutrition log, do not use the wing or drumstick's total bone-in weight as if every gram were edible meat. Weigh the edible portion or use a database entry designed for the bone-in serving.
Why Raw and Cooked Chicken Have Different Protein per 100g
The main reason is water loss. Raw poultry contains a large amount of water. During roasting, grilling, pan-cooking, or baking, part of that water evaporates and some juices are lost. The final cooked piece therefore weighs less.
Imagine 130 g of raw chicken contains about 29 g of protein. After cooking, it might weigh around 100 g because water was lost. The protein did not suddenly increase; the same protein is now contained in a smaller mass. On a per-100-g basis, the cooked food looks more protein-dense.
Chicken Breast vs Thigh vs Other Cuts
Breast usually wins for protein density, while thigh offers more fat and a richer texture. Both can fit a balanced diet, and the better choice depends on energy needs, taste, budget, and the rest of the meal.
Chicken Breast
Lean, relatively low in fat, and commonly around 30–31 g protein per 100 g when cooked and skinless.
Chicken Thigh
Dark meat with more fat and usually slightly less protein per 100 g than breast, though still protein-rich.
Drumstick
Dark meat similar to thigh. Bone-in weights can mislead because the entire weighed portion is not edible meat.
Chicken Wings
Protein-rich meat but often eaten with skin and sauces, so calories and fat can rise quickly relative to edible meat.
How Much Protein Is in 150g, 200g, or 250g of Chicken?
Once you know the correct per-100-g value, scale it proportionally. For cooked skinless breast at 31 g protein per 100 g, the calculation is straightforward.
| Cooked chicken breast | Calculation | Approx. protein |
|---|---|---|
| 100 g | 1.0 × 31 g | 31 g |
| 150 g | 1.5 × 31 g | 46.5 g |
| 200 g | 2.0 × 31 g | 62 g |
| 250 g | 2.5 × 31 g | 77.5 g |
| 300 g | 3.0 × 31 g | 93 g |
This is a mathematical conversion, not a guarantee about your exact food. Use your product label or the matching database entry when precision matters.
Step-by-Step: Track Chicken Protein More Accurately
- Identify the cut. Choose breast, thigh, drumstick, wing, ground chicken, or a processed product.
- Check skin and bone. Skin-on and bone-in entries are not interchangeable with skinless edible meat.
- Decide raw or cooked. Weigh the food in the same state used by your nutrition entry.
- Choose the closest database record. Match cooking method where possible: roasted, grilled, stewed, or generic cooked.
- Use the package label for branded products. Added solution, marinades, breading, or processing can change nutrition.
- Scale from 100 g. Multiply the listed protein by your portion weight divided by 100.
- Stay consistent. Using the same method from meal to meal is often more useful than switching between mismatched entries.
Common Mistakes When Counting Chicken Protein
Most large tracking errors come from mismatched food states rather than arithmetic. Watch for these issues:
- Using a cooked breast value for chicken weighed raw.
- Counting bone-in weight as if all 100 g were edible meat.
- Ignoring skin, breading, sauces, or oil when comparing calories and macros.
- Assuming every database entry represents the same chicken cut and cooking method.
- Using restaurant estimates as though they were laboratory measurements.
- Believing a higher cooked protein-per-100-g number means cooking created more protein.
Practical Examples
200 g Cooked Breast
If your matching entry lists 31 g protein per 100 g, a 200 g cooked portion gives about 62 g protein.
200 g Raw Breast
Use the raw entry, perhaps around the low-20s grams protein per 100 g, rather than a cooked 31 g value.
250 g Drumsticks
Do not multiply 250 g by an edible-meat value unless the bones are excluded. Use an appropriate bone-in entry or weigh the edible meat.
Chicken Protein Tracking Checklist
Before you log the meal, confirm:
- Which cut you ate
- Whether skin was included
- Whether your weight is raw or cooked
- Whether bones were included in the scale weight
- Whether the food was plain, marinated, breaded, or processed
- Whether the database entry matches the preparation
- Whether a brand label is available and more specific

Summary: Protein in Chicken per 100g
For everyday planning, cooked skinless chicken breast is commonly estimated at about 30–31 g of protein per 100 g. Raw breast is lower per 100 g because it contains more water, while cooked thigh generally contains slightly less protein and more fat than breast.
The most important rule is consistency: pair raw weights with raw database entries and cooked weights with cooked entries. Also account for skin, bone, added solutions, sauces, breading, and brand-specific labels. Cooking concentrates protein per 100 g mainly by removing water; it does not manufacture extra protein.
Frequently Asked Questions
These answers address the most common questions behind searches for chicken protein by weight.
How much protein is in 100g of chicken breast?
Cooked, skinless chicken breast commonly provides about 30–31 g of protein per 100 g. Raw skinless breast is usually lower per 100 g because it contains more water before cooking. Exact values vary by database entry, bird, trimming, added solution, and cooking method.
How much protein is in 100g of chicken thigh?
Cooked chicken thigh generally contains less protein per 100 g than cooked breast because thigh has more fat and a different moisture profile. A practical estimate for cooked, skinless thigh is in the mid-to-high 20-gram range per 100 g, but the exact number depends on preparation and whether skin is included.
Why does cooked chicken show more protein per 100g than raw chicken?
Cooking removes water. The chicken does not create extra protein; instead, the same protein becomes concentrated into a lighter cooked portion. That is why 100 g of cooked chicken can contain more protein than 100 g of the same cut weighed raw.
Is 100g of chicken the same as 100g of protein?
No. Chicken is a food that contains protein, water, fat, vitamins, and minerals. Depending on the cut and whether it is raw or cooked, 100 g of chicken may contain roughly 20–31 g of protein rather than 100 g of protein.
How much protein is in 200g of chicken breast?
If your cooked chicken breast contains about 31 g of protein per 100 g, then 200 g provides about 62 g. If you weigh it raw, use a raw-food value rather than multiplying a cooked value, because cooking changes the water weight.
Does chicken skin change the protein per 100g?
Yes. Skin adds fat and changes the proportion of protein, fat, and water in each 100 g. For protein-focused tracking, compare like with like: skinless breast with skinless breast, and cooked entries with cooked entries.
Which chicken cut has the most protein per 100g?
Skinless cooked chicken breast is typically one of the most protein-dense common chicken cuts by weight. Dark-meat cuts such as thigh can still be excellent protein sources but usually contain more fat and slightly less protein per 100 g.
What is the safest temperature for cooked chicken?
USDA food-safety guidance recommends that poultry reach a minimum internal temperature of 165°F (73.9°C), measured with a food thermometer in the appropriate thickest or innermost part. Food safety should not be judged only by color.
Should I track chicken protein using raw or cooked weight?
Either can work if you are consistent. The simplest method is to weigh the chicken in the same state as the nutrition entry you use. If the database entry says raw, weigh raw; if it says cooked or roasted, weigh cooked.
Can nutrition labels and food databases give different chicken protein values?
Yes. Differences can come from cut, skin, bone, cooking loss, added water or solution, laboratory sampling, brand formulation, and rounding. Use the entry that most closely matches the chicken you actually ate.
Use the Right Number for the Chicken You Actually Ate
The headline figure—roughly 30–31 g protein per 100 g of cooked skinless breast—is useful, but accurate tracking depends on context. The cut, skin, bone, raw-or-cooked state, and preparation method all matter.
For most people, consistent estimates from a reputable database or package label are more practical than searching for a single “perfect” number. For academic work, document the food-composition source and basis clearly so readers can understand exactly what your values represent.
