If you're the meat and potatoes type, you'd love a big, juicy steak that covers your plate. But a 16-ounce prime rib can have about 1,600 calories and about 60 grams of "bad" fat. That's without any sides or appetizers.
Better Bet: Lean meat, such as sirloin, tenderloin, or flank steak. The piece should be the size of your fist, not your plate.
