Sirloin Tip Steak
If you crave red meat, have this cut on hand. Packed with beef's awesome protein profile and strength-boosting iron levels, sirloin tip has had the fat trimmed away, so it's lower in calories yet packs big flavor. A 3-ounce serving (about the size of your phone) has 210 calories and 4 grams of saturated fat, says Silber, which is less than the 13-gram saturated fat limit suggested by the American Heart Association. Make sure the kind you buy is grass-fed and antibiotic-free, so you avoid harmful additives, says Silber.
