The chef's caveat

Raw → Cooked

Meat loses roughly 25% of its weight to water during cooking. 4 oz raw becomes about 3 oz cooked. Every number here is for cooked weight — if your scale or recipe reads raw, multiply by 0.75 first.

Common questions

The stuff people actually ask.

How many calories in serving 2 oz of chicken breast?

About 75 calories, with roughly 8.2g of protein. serving 2 oz weighs about 56g. Use the slider above for any other portion.

Grilled vs. baked vs. pan-seared — do the calories differ?

Not from the cooking method itself. All three yield roughly the same numbers per 100g cooked. What changes calories is what you add: a tablespoon of olive oil is +120 cal, a sugary marinade can add 40–80 per portion.

Is chicken breast actually healthy, or is that marketing?

By the numbers on this page: balanced enough that "healthy" is the wrong axis. It is food.
