How Much Protein in a Chicken Breast? The Numbers

A standard boneless, skinless chicken breast (raw) packs about 31 grams of protein per 100 grams (3.5 oz). For context:

**Small breast** (4 oz or 113g raw): ~35g protein

**Medium breast** (6 oz or 170g raw): ~53g protein

**Large breast** (8 oz or 227g raw): ~70g protein

Key factors affecting protein content:

**Cooking method**: Grilling, baking, or boiling reduces water content, concentrating protein per gram.

**Fat trim**: Removing skin and fat keeps it lean.

**Bone-in vs. boneless**: Bone-in breasts yield slightly less edible meat.

💡 Pro Tip: Use a food scale for precision—eyeballing portions can skew your protein math!

Raw vs. Cooked: Why Preparation Matters

When you cook chicken, water loss increases protein density per 100g. Here’s a worked example:

1. Raw chicken: 200g breast = 62g protein (31g per 100g).

2. After grilling: Loses ~30% water weight → 140g cooked breast.

3. Result: Still 62g protein, but now 44g per 100g (up from 31g).

Rule of thumb:

**100g raw chicken** = ~31g protein

**100g cooked chicken** = ~31–44g protein (depending on cooking time/method)

🔥 High-heat methods (like grilling) evaporate more water, boosting protein concentration per gram.

Real-Life Examples: Calculating Your Intake

Let’s put this into practice:

**Example 1**: You grill a 6oz (170g) raw chicken breast.

- Raw protein: 170g × 0.31 = 53g

- Cooked weight: ~120g (30% water loss)

- Cooked protein: 53g (44g per 100g)

**Example 2**: You boil a 4oz (113g) breast.

- Raw protein: 113g × 0.31 = 35g

- Cooked weight: ~90g (20% water loss)

- Cooked protein: 35g (39g per 100g)

Bottom line: Track raw weight for accuracy, but account for cooking losses when logging meals.

Why Protein Matters for Your Goals

Protein supports muscle repair, weight management, and satiety. For most adults:

**Sedentary**: 0.8g protein/kg body weight

**Active**: 1.2–1.6g/kg

**Athletes**: 1.6–2.2g/kg
