Raw Chicken Breast Nutrition: Calories, Protein & Macros

Calculate Nutrition for Your Raw Chicken Breast

Chicken breasts vary considerably in size, so I prefer using weight instead of terms such as "one medium breast." Most people don't eat exactly 100 grams of chicken. If you've already weighed your raw portion, enter that number below and we'll scale the nutrition values from the same raw chicken reference used on this page.

How the Calculation Works

If the selected USDA record contains 22.5 grams of protein per 100 grams, a 200-gram raw portion would contain about 45 grams of protein. That is a calculated serving value, not a separate laboratory measurement of your particular chicken breast. Natural foods can vary slightly in composition.

Raw Chicken Breast Nutrition Facts per 100g

The most important thing about any chicken nutrition table is knowing exactly what food the numbers describe. The table on this page refers to:

The site's nutrition database should display the exact USDA FoodData Central record and use that same record for every value on this page. Plain raw chicken breast is primarily water and protein. It contains little fat and essentially no carbohydrate. It also provides micronutrients such as phosphorus, selenium, niacin and vitamin B6, although the exact values should always come directly from the selected USDA record rather than being copied between unrelated chicken entries.

What Stands Out?

Raw, skinless chicken breast is mostly water and protein, with relatively little fat and essentially no carbohydrate. The important point for tracking is not whether chicken is a "good" or "bad" food. It is that you match your food-scale measurement with the correct database state. If the chicken was raw when you weighed it, use raw nutrition data. That simple habit prevents many of the confusing discrepancies people see in calorie-tracking apps.

Raw Chicken Breast Nutrition by Weight

If your chicken portion isn't exactly 100 grams, you don't need to find another article. Use the serving-size table or calculator. Rather than creating separate pages for each portion, this table automatically calculates common serving sizes from the same raw reference.

Values other than the reference serving are calculated mathematically from the selected USDA record and rounded for practical use. Each serving value is calculated from the same USDA raw reference. That approach is more consistent than using one nutrition source for 100 grams, another for four ounces and another for six ounces.

How to Track Raw Chicken Correctly

If you're tracking calories or macros, this is the approach I recommend because it keeps things simple:

Why Does Cooked Chicken Have More Calories and Protein per 100g?

This is probably the most common question I see when people compare chicken nutrition numbers. This is one of the most confusing parts of chicken nutrition, so let's make it simple.

Imagine you start with a piece of raw chicken that contains protein, fat and a lot of water. During cooking, some of that water leaves the meat. The cooked piece therefore weighs less.

The protein hasn't suddenly appeared from nowhere. There is simply less water sharing the same weight. That means: 100 g raw chicken and 100 g cooked chicken are not the same original amount of meat. This is why cooked chicken often shows more calories and more protein per 100 g.

Healthline, for example, currently gives about 31 to 32 g protein per 100 g for cooked chicken breast, while the USDA raw-breast reference used for raw tracking is around 22.5 g protein per 100 g. These numbers describe different states of the food rather than a magical increase in protein during cooking.

Is It Better to Weigh Chicken Raw or Cooked?

Either method can work if your nutrition entry matches the state you weighed. For home cooking, weighing raw ingredients can be particularly convenient because you know the amount before moisture loss makes the final weight less predictable.

But there are situations where cooked weight is easier. For example, if you batch-cook several chicken breasts and divide them between meals later, you may prefer to weigh the cooked portions.

The key isn't that one method is universally "correct." The key is consistency:

• Raw weight: Use a raw database entry (raw chicken -> use raw nutrition data).
• Cooked weight: Use a cooked entry that matches the preparation as closely as practical (cooked chicken -> use cooked nutrition data).

I personally like this rule because it removes most of the confusion. That is more reliable than weighing cooked chicken and logging raw values. You don't need to constantly convert between raw and cooked weights if your database entry already matches your measurement.

What About Batch Cooking?

What if I cook several raw chicken breasts together?

Batch cooking is where people often run into trouble. Suppose you begin with: 1,000 g raw chicken breast.

You can record the nutrition for the full 1,000 g raw batch before cooking. After cooking, weigh the finished batch. For example:

This method is often more useful than trying to guess a universal raw-to-cooked conversion.

Does Chicken Always Lose the Same Amount of Weight?

No. Do not assume chicken always loses 25% of its weight. Actual yield can vary with:

• thickness
• cooking method
• cooking time
• endpoint temperature
• starting water content
• brining
• injected solution
• resting
• how aggressively the meat is cooked

Any site's raw-to-cooked calculator must therefore call its result estimated cooked weight unless it is based on the user's measured batch. If accuracy matters, weighing your own batch before and after cooking is better.

Why Can Two Raw Chicken Breasts Have Slightly Different Nutrition?

If you've seen different numbers for raw chicken in two tracking apps, don't assume one must be completely wrong. Nutrition databases are reference tools, not laboratory tests of the exact piece sitting on your kitchen scale. Real chicken can vary because of differences in:

What About Packaged Chicken?

Generic USDA chicken vs packaged chicken

This is another detail worth checking. Some packaged chicken breasts contain added water, broth, sodium, seasoning, or other ingredients.

Use USDA data when you're working with a generic food such as plain raw boneless, skinless chicken breast. Use the product label when you're eating a branded or enhanced chicken product whose formulation differs from plain chicken. This is particularly important when sodium or added ingredients are present. Always read the label rather than assuming every raw chicken breast has exactly the same composition.

Does Raw Chicken Breast Have Carbohydrates?

Plain raw chicken breast contains essentially no carbohydrate.

If your tracking app shows meaningful carbohydrates for plain raw chicken breast, check whether you've selected:

• a breaded product
• a seasoned product
• a marinade
• a ready-to-cook commercial product
• or a product containing starch or sugar

rather than plain meat. The same applies after cooking. Carbohydrate usually comes from added ingredients, not from plain chicken breast itself.

How Much Protein Is in Raw Chicken Breast?

A USDA raw boneless, skinless chicken-breast reference provides about 22.5 g of protein per 100 g raw. That makes common raw-weight portions easy to estimate.

For example: 200 g raw ≈ 45 g protein before accounting for normal rounding and natural food variation. The calculator above does this automatically so you do not need to calculate it manually.

Important: The finished cooked chicken may weigh much less than 200 g. That does not mean the cooking process erased a large portion of its protein. Most of the weight difference is water.

Should I Use 106, 120 or Another Number for Raw Chicken?

This is exactly the kind of confusion our website should address instead of hiding. Different food databases may show somewhat different raw chicken values because they can be based on:

• different food records
• historical versus newer datasets
• different analytical samples
• different fat levels
• different energy-calculation approaches

For that reason, ChickenBreastNutrition.com should not mix calorie values from several records. We select one clearly identified USDA record, display its FoodData Central ID (FDC ID 2646170), and use that same record for the nutrition table, serving-size calculations, and calculator results. If the reference record changes in the future, our methodology and update history will say so. That gives you something more useful than a number without context.

From Raw Weight to Cooked Weight: Our Kitchen Test Note

Handle Raw Chicken Carefully

How We Source Raw Chicken Nutrition Data

For generic raw chicken breast, our preferred source is USDA FoodData Central. USDA's Foundation Foods include nutrient information based on analyzed samples of minimally processed foods and provide information intended to help users understand food composition and variability.

For this page, the database record specifically represents: chicken breast, boneless, skinless, raw (Foundation Food FDC ID 2646170). We do not substitute cooked chicken data or manufacturer-specific product information into this generic raw-food table.

Our Labels

We make those distinctions because nutrition information is far more useful when you know exactly where the number came from.
