Here’s how 3 ounces of the leanest cuts of cooked beef compare. Expect grass-fed beef to best these numbers across the board; total fat in a 3-ounce serving of grass-fed beef can be as little as 2.2 grams, less than in a skinless chicken breast, at 3.0 grams.
Chuck arm pot roast
Eye round, extra-lean
Top round, extra-lean
Notes: Beef cuts are based on 3-ounce cooked servings, separable lean only (muscle tissue with internal marbling), trimmed to one-quarter-inch fat, all grades.
