Understanding the Nutritional Differences: Raw vs. Cooked
One of the most important factors influencing the nutritional information for chicken breast is whether it is measured raw or cooked. As meat cooks, it loses a significant portion of its water content, which concentrates the remaining nutrients and calories. This means a 120-gram portion of cooked chicken will have a higher concentration of calories and protein than an equivalent 120-gram portion of raw chicken. The raw-to-cooked ratio is typically around a 25% weight loss during cooking, though this can vary.
Nutritional Values for 120g Chicken Breast
To provide a clear picture, here is a breakdown based on different states and preparations:
- Raw, Boneless, Skinless Chicken Breast: A 120g portion contains approximately 144 calories and 27 grams of protein. This is the base nutritional value before any moisture is lost.
- Cooked, Boneless, Skinless Chicken Breast (Baked or Roasted): A 120g portion, as detailed by the USDA, offers about 193-198 calories and 36-37 grams of protein. This higher density is due to the water loss during cooking.
- Cooked, Boneless, Skinless Chicken Breast (Pan-fried with no coating): Frying can slightly increase the calorie count due to the absorption of some oil. A 120g portion contains approximately 211 calories and 36 grams of protein.
- Cooked Chicken Breast with Skin (Roasted): Including the skin significantly increases the fat and calorie content. A 120g portion of roasted chicken breast with skin contains roughly 236 calories.
The Impact of Cooking Methods
Beyond the raw-versus-cooked distinction, the way you prepare your chicken breast dramatically affects the final nutritional profile. Healthy cooking methods add minimal extra calories, preserving chicken's status as a lean protein powerhouse. Conversely, frying or adding heavy sauces can quickly increase the overall caloric intake.
- Baking and Roasting: These methods use dry heat, allowing the chicken to cook in its own juices or with minimal added fat. They are excellent for preserving a lean profile.
- Grilling: Similar to baking, grilling adds a smoky flavor without piling on extra calories, provided you use little to no oil.
- Poaching and Boiling: Cooking chicken in water or broth is one of the most effective ways to keep the calorie count to a minimum, as no fat is added.
- Frying (Deep Frying): This method involves submerging the chicken in hot oil, which can add a significant amount of fat and calories to the final dish.
- Pan-Frying (Sautéing): Using a small amount of oil for pan-frying can add some fat, but it is generally less caloric than deep-frying. The type of oil used (e.g., olive oil vs. butter) also matters.

| Preparation Method | Calories (approx.) | Protein (g) (approx.) | Fat (g) (approx.) | Notes |
|---|---|---|---|---|
| Raw, Skinless | 144 | 27 | 3 | Baseline for calculation. |
| Cooked, Skinless (Baked) | 193-198 | 36-37 | 4.3 | Most common healthy preparation. |
| Cooked, Skinless (Pan-fried) | 211 | 36 | 7 | Includes a small amount of added oil. |
| Cooked, with Skin (Roasted) | 236 | ~25 | ~11 | Significantly higher in fat and calories. |
| Cooked, Sliced Grilled (pre-cooked) | 155 | 35 | 4 | Note higher sodium in some pre-cooked. |
The Health Benefits of Lean Chicken Breast
Beyond the basic macronutrient numbers, lean chicken breast is a healthy food for several reasons. It is a complete protein, meaning it contains all nine essential amino acids necessary for muscle repair, immune function, and overall health. As a low-fat source, especially when the skin is removed, it helps support weight management by promoting satiety. Chicken also provides a variety of important micronutrients, including B vitamins, selenium, phosphorus, and zinc, which are crucial for energy production, bone health, and immune system support. Its versatility in the kitchen also makes it an easy and budget-friendly option for healthy meal preparation.

Conclusion
In summary, 120 grams of cooked, boneless, skinless chicken breast is a highly nutritious and lean protein source, typically containing around 193-198 calories and 36-37 grams of protein. The precise figures can fluctuate based on the initial state of the meat (raw vs. cooked) and how it's prepared. Opting for healthy cooking methods like baking or grilling ensures you maximize the health benefits while keeping the calorie and fat content low. This makes it an ideal food for individuals focused on fitness, weight management, and general wellness.
The Takeaway
The high-protein, low-calorie profile of chicken breast, particularly when prepared without excess fat, solidifies its reputation as a staple in healthy diets. By being mindful of preparation techniques, you can easily control your caloric intake while benefiting from its many nutritional advantages. This makes it a smart choice for fueling your body and achieving your health goals.
