How much protein is in 1 lb of 80/20 ground beef?

One pound of raw 80/20 pasture-raised ground beef provides 88.5 grams of pure protein and approximately 7.5 grams of L-leucine.

Does draining fat from ground beef reduce protein?

No. Draining pan drippings only removes rendered liquid triglycerides and moisture; the muscle protein remains 100% bound within the cooked meat crumbles.

Why does cooked ground beef weigh less than raw ground beef?

Ground beef loses approximately 20% to 24% of its mass to water evaporation and additional weight to rendered fat, yielding 11 to 12.5 oz of cooked meat per pound.

How much protein is in 4 oz of cooked 80/20 ground beef?

Four ounces of cooked and drained 80/20 ground beef delivers approximately 28g to 30g of protein and 14g of fat (~240 kcal).

Does hot water rinsing ground beef remove all fat?

Hot water rinsing removes up to 70%–75% of total fat, but it also washes away water-soluble B vitamins, carnitine, and intracellular minerals. Draining in a colander without rinsing is nutritionally superior.

How much protein does 1 lb of 90/10 ground beef yield compared to 80/20?

One pound of raw 90/10 ground beef yields 97.5g of pure protein (vs 88.5g in 80/20), delivering an additional 9g of protein and 45g less fat per pound.
