The Calculation: Determining Protein Content in 330g of Cooked Chicken Breast
Understanding the protein content of cooked chicken breast starts with a simple calculation based on established nutritional averages. For cooked, skinless, boneless chicken breast, the standard reference point is approximately 31 grams of protein per 100 grams of meat. This metric accounts for the moisture loss that occurs during the cooking process, which concentrates the protein by weight.
To find the total protein in a 330g serving, you can use the following formula:
- Step 1: Determine the number of 100g servings in your 330g portion. $330g / 100g = 3.3$
- Step 2: Multiply this number by the average protein content per 100g. $3.3 \times 31g = 102.3g$
Therefore, 330 grams of cooked chicken breast contains approximately 102.3 grams of protein. It is important to note that this is an estimation, and the actual amount can vary slightly depending on factors like the cooking method and the specific chicken cut.
Cooked vs. Raw: Why the Protein per 100g Changes
One common point of confusion is why the protein amount per 100 grams is higher in cooked chicken compared to raw. When chicken is cooked, it loses a significant amount of water through evaporation. The protein itself does not disappear; it simply becomes more concentrated in the remaining mass of the chicken. A 100g raw chicken breast might have around 22-27g of protein, but after cooking, its weight shrinks while its protein mass stays constant, leading to a higher protein percentage by weight.
Here’s a quick breakdown of the difference:
- Raw Chicken: Contains a higher water weight, so the protein per 100g is lower.
- Cooked Chicken: Water is lost, resulting in a denser, higher protein-per-100g ratio.
- Total Protein: The total amount of protein in a single breast remains consistent before and after cooking, assuming no part of the meat is lost.
Factors Influencing the Exact Protein Amount
While 102.3 grams is a reliable estimate, several factors can cause slight variations in the final protein count:
- Cooking Method: Different methods, such as boiling, grilling, or roasting, result in varying degrees of moisture loss, slightly impacting the final concentrated weight.
- Skin-on vs. Skinless: This calculation assumes a skinless breast. Leaving the skin on adds a significant amount of fat and calories, changing the protein's proportion of the total calories.
- Meat Quality and Genotype: The specific breed and health of the chicken can play a role. Conditions like “white striping” can alter the meat’s composition, leading to lower protein and higher fat content.
Comparison of Chicken Cuts: Protein Content per 100g (Cooked)
To put the chicken breast's protein density into context, here is a comparison with other popular cuts of chicken, all cooked:
| Chicken Cut | Approximate Protein (per 100g) | Fat (per 100g) |
|---|---|---|
| Chicken Breast (skinless) | ~31 grams | ~3.6 grams |
| Chicken Thigh (skinless) | ~26 grams | ~11 grams |
| Chicken Drumstick (skinless) | ~28 grams | ~5.7 grams |
| Chicken Wing (skinless) | ~30.5 grams | ~8.2 grams |
As the table shows, skinless chicken breast offers the highest protein-to-fat ratio, making it the leanest choice. This is why it is often the preferred option for bodybuilders and those managing their weight.
Additional Nutritional Benefits of Cooked Chicken Breast
Beyond its high protein content, cooked chicken breast provides a range of other essential nutrients:
- B Vitamins: It is an excellent source of B vitamins, particularly niacin (B3), pyridoxine (B6), and cobalamin (B12). These vitamins are crucial for energy metabolism and cell health.
- Minerals: It contains vital minerals such as selenium, which acts as a powerful antioxidant, and phosphorus, important for bone health.
- Essential Amino Acids: The protein in chicken breast is a complete protein, meaning it provides all nine essential amino acids that the human body cannot produce on its own.
Integrating a 330g Serving into Your Diet
A serving size of 330g of chicken breast is substantial and can be a powerful tool for meeting high daily protein targets, especially for athletes or those on a muscle-building regimen. For reference, many fitness experts recommend consuming 30–40 grams of protein per meal to maximize muscle protein synthesis. A 330g portion easily covers this target multiple times over, making it suitable for a large single meal or for meal prep spread across several smaller meals.
For balanced nutrition, pair this protein source with complex carbohydrates like brown rice or quinoa and plenty of vegetables. This ensures you get a full spectrum of nutrients while remaining in a calorie-controlled framework if needed. Consider grilling or baking the chicken breast for the leanest results.

Conclusion
In summary, 330g of cooked, skinless chicken breast contains approximately 102.3 grams of high-quality protein, a significant amount for any dietary regimen. This value is higher per 100g than raw chicken due to the loss of water during cooking. While slight variations can occur based on the cooking method and meat quality, chicken breast remains a top-tier source of lean protein, B vitamins, and essential minerals, making it a cornerstone of a healthy, active diet.
