In-N-Out Burger's Hamburger With Onion, Protein Style

Health-conscious Californians love to order their burgers from this West Coast chain "protein style," which means the bun is replaced with a lettuce wrap. (The simple swap can save you 150 calories and 28 grams of carbohydrates.)

Here, a hamburger with onion and no bun has 240 calories, 17 grams of fat (4 grams saturated), and 370 milligrams of sodium; ask for ketchup and mustard instead of their signature spread to save another 80 calories.
