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 oz of beef?

About 78 calories, with roughly 5.1g of protein. oz weighs about 28.35g. 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 beef actually healthy, or is that marketing?

By the numbers on this page: dense in unsaturated fat, fiber, and micronutrients — the "high calorie ≠ unhealthy" case in food form.
