4 min read

According to the USDA, a 3.5-ounce (100g) serving of cooked, skinless, boneless chicken breast contains 31 grams of protein, making it one of the most efficient lean protein sources available. Understanding what are the macros of a chicken breast is key for anyone focusing on fitness, weight management, or general healthy eating. This detailed breakdown will help you integrate this dietary staple into your meals effectively.

Quick Summary

This guide provides a comprehensive breakdown of the macronutrients found in chicken breast, specifically focusing on a cooked, skinless, boneless serving. The content covers the primary macros—protein, fat, and carbs—as well as how cooking methods and preparations influence its nutritional profile, helping you make informed dietary choices.

Key Points

  • High-Protein, Low-Fat: A 100g serving of cooked, skinless chicken breast provides approximately 31g of protein and only 3.6g of fat.

  • Carb-Free: Chicken breast contains zero carbohydrates, making it ideal for low-carb and ketogenic diets.

  • Cooking Method Matters: Healthy cooking methods like grilling, baking, or poaching are key to maintaining the lean macro profile of chicken breast.

  • Skin-on Adds Fat: Eating the skin significantly increases the fat and calorie content of the chicken breast.

  • Aids Weight Management: The high protein content promotes satiety, which helps with appetite control and weight loss goals.

  • Versatile for Meal Prep: Chicken breast is a versatile and convenient option for meal prepping healthy, protein-rich meals.

A Closer Look at the Macronutrients

The appeal of chicken breast as a dietary powerhouse comes from its impressive macronutrient ratio, especially its high protein-to-fat composition. When prepared simply, without skin or excess fat, it provides a lean, concentrated source of protein essential for building muscle, aiding satiety, and supporting overall health. The macros can, however, shift significantly depending on how you prepare and serve it.

The Standard Macronutrient Breakdown

For a standard 3.5-ounce (100g) serving of cooked, skinless, boneless chicken breast, the macronutrient profile is remarkably straightforward and balanced, especially for those on a high-protein, low-fat diet:

  • Protein: Approximately 31 grams. This accounts for the vast majority of its calories.
  • Fat: A low 3.6 grams. This includes both saturated and unsaturated fats, with the saturated fat content being minimal.
  • Carbohydrates: 0 grams. Chicken breast is naturally carb-free, making it an excellent option for low-carb and ketogenic diets.
  • Calories: Roughly 165 calories, with around 80% coming from protein and 20% from fat.

Factors That Affect Chicken Breast Macros

Not all chicken breast is created equal. The final macronutrient and calorie count can vary significantly based on a few key factors. Being mindful of these can help you better track your intake.

Raw vs. Cooked Macros

It is important to note the distinction between raw and cooked macros. When chicken breast is cooked, it loses water weight, which concentrates the remaining nutrients. This means a 100g serving of cooked chicken will have a higher protein and calorie density than a 100g serving of raw chicken, even though the total nutritional content from the original piece remains the same. To ensure accuracy when tracking macros, it is generally recommended to measure cooked chicken.

Skin On vs. Skinless

Choosing skin-on over skinless chicken breast dramatically changes the macro profile, particularly the fat content. Leaving the skin on adds a significant amount of fat and calories. For example, a 3.5-ounce serving with the skin on can increase the fat to around 8 grams and the total calories to over 200, though the protein content remains similar.

Impact of Cooking Methods

Your cooking method also plays a crucial role in the final macro count. Certain preparations can add extra calories and fat, while others preserve the natural lean state of the meat. Healthy cooking methods include grilling, baking, poaching, or steaming, all of which require minimal to no added fats. In contrast, frying or sautéing with generous amounts of oil, or adding creamy, high-fat sauces can substantially increase the calorie and fat content.

Best Cooking Methods for Maximizing Macros:

  • Grilling: Adds a smoky flavor with no extra fat. Perfect for meal prep and salads.
  • Baking: A simple, hands-off method that keeps the chicken juicy, especially when seasoned with herbs and spices.
  • Poaching: Cooks the chicken in a liquid (like broth or water) to keep it tender and moist with no added fat.
  • Steaming: A gentle method that locks in moisture and nutrients, ideal for a low-calorie diet.

Chicken Breast vs. Chicken Thigh: A Macro Comparison

For those debating between different cuts of chicken, a comparison of the macro profiles can be helpful. While both are excellent protein sources, they differ in their fat and calorie content.

Feature Skinless, Boneless Chicken Breast (per 100g, cooked) Skinless, Boneless Chicken Thigh (per 100g, cooked)
Calories ~165 kcal ~144 kcal
Protein ~31g ~18.6g
Fat ~3.6g ~7.92g
Carbohydrates 0g 0g

As the table shows, chicken breast offers a higher protein content with less fat and fewer calories per 100g than chicken thigh. This makes it the preferred choice for those aiming for maximum protein intake with minimal fat. Chicken thighs, while still a healthy option, offer more flavor and juiciness due to their higher fat content.

Incorporating Chicken Breast into Your Diet

Due to its nutritional profile, chicken breast is an incredibly versatile ingredient for a variety of diet plans. Its high protein content contributes to satiety, helping with appetite control and weight management.

Meal Prep Ideas:

  • Lemon Herb Chicken: Marinate chicken breasts in a simple mixture of lemon juice, olive oil, garlic, and herbs before baking or grilling. This can be prepped in bulk for easy lunches throughout the week, paired with roasted vegetables or quinoa.
  • Shredded Chicken: Slow cook or instant pot chicken breasts and shred them for use in wraps, salads, or burritos.
  • Chicken and Veggie Stir-fry: Quickly cook sliced chicken breast with a variety of vegetables in a wok with minimal oil and a low-sodium sauce for a balanced, healthy meal.

Conclusion

When considering what are the macros of a chicken breast, it is clear that it stands out as an exceptionally lean and efficient source of protein. A 100g serving of cooked, skinless, boneless chicken breast provides a concentrated dose of protein with virtually no carbohydrates and very little fat, making it a cornerstone for those focused on muscle building, weight loss, or simply maintaining a healthy, balanced diet. By choosing healthy cooking methods and being mindful of additions like skin or heavy sauces, you can harness the full nutritional potential of this versatile food.
