Beef is basically 81% protein by calorie. Not many foods in the aisle read that clean.

Cottage cheese, skyr, and canned tuna hit the same range. Most things marketed as "high protein" land in the 30–45% band.

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 10 slices of beef?

About 43 calories, with roughly 8.7g of protein. 10 slices weighs about 28g. 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: high protein, low fat, near zero sugar. Hard to argue with.
