100g of cooked, skinless chicken breast contains approximately 31-33 grams of protein. This is one of the highest protein densities among common foods.

How to Measure Consistently
- Weigh chicken breast after cooking for accurate protein tracking, as cooking reduces weight due to water loss.
- A typical medium cooked chicken breast (boneless, skinless) weighs about 120g and provides approximately 37-40g protein.
- Use a kitchen scale rather than estimating by size, as chicken breasts vary significantly in weight.
- If meal prepping, cook and weigh all portions at once, then divide into containers for consistent protein amounts.
- For skinless vs with skin: remove skin before weighing if you want to track just the meat, or weigh with skin if that's how you'll eat it.
What Changes the Number
- Skin: chicken breast with skin has similar protein per gram of meat but adds significant calories and fat from the skin.
- Cooking method: grilling, baking, or roasting causes water loss, making cooked chicken breast denser and higher in protein per gram.
- Size variation: chicken breasts can range from 100g to 200g+ when cooked, so weighing is essential for accuracy.
- Cooking time: overcooking can cause more water loss, concentrating protein per gram but potentially making the meat dry.
- Preparation: marinated or seasoned chicken breast has the same protein content, but added ingredients affect total calories.
