3. Change Your Steak Order

A 6-ounce sirloin contains 300 calories and only 3 grams of saturated fat. That's 100 fewer calories and 6 fewer grams of saturated fat than the same-size rib-eye steak, says Holly Herrington, a registered dietitian at the Center for Lifestyle Medicine at Northwestern University. If sirloin isn't on the menu, ask your waiter what lean and extra-lean cuts are available (or your butcher, if you're doing steakhouse night at home). Those cuts are from the more muscular parts of the animal, so not only do they contain fewer calories, but a greater percentage of those calories come from protein rather than fat.
