A standard cooked, skinless chicken breast has about 50–55 g of protein in a typical full piece (~170 g), which works out to roughly 31 g of protein per 100 g of cooked meat.

Quick Scoop

  • 100 g cooked, skinless chicken breast: ≈31 g protein.
  • Typical medium breast (about 170 g / 6 oz cooked): ≈50–55 g protein.
  • Per ounce cooked: ≈8 g protein.
  • Very low in carbs (essentially 0 g) and relatively low in fat, making it a lean protein choice.

A quick mental shortcut many lifters and dieters use:

“One decent-sized cooked chicken breast = about 50 g of protein.”

What Changes the Exact Number?

The exact protein number can shift slightly based on:

  1. Raw vs. cooked
    • Cooking reduces water, so protein per gram goes up a bit after cooking.
 * But a “breast” on your plate will usually be weighed cooked in tracking apps.
  1. Size of the breast
    • Small breast (~120 g cooked): ~35–40 g protein.
    • Large breast (~200 g cooked): ~60+ g protein.
  1. Skin and breading
    • Skin and breading add fat and calories , but the protein in the meat stays similar per gram of meat.

Typical Nutrition Snapshot (100 g Cooked, Skinless Breast)

Here’s a simple breakdown for about 100 g cooked, roasted, skinless chicken breast:

This is why chicken breast is such a go-to for muscle gain, fat loss, and high-protein diets in 2025–2026 fitness trends.

Quick Example for Your Plate

If you’re tracking protein:

  • Grilled chicken wrap with ~150 g chicken breast inside → about 45–47 g protein.
  • Meal prep box with two small breasts totaling ~250 g cooked → about 75–80 g protein.
