7 Unhealthiest Fast-Food Burgers That Can Pack on Pounds—And 7 Healthier Options

Registered dietitians uncover the unhealthiest fast-food burgers and recommend better-for-you alternatives.
FACT CHECKED BY Olivia Tarantino

When you're craving a fast-food burger, oftentimes your eyes are bigger than your calorie limit. While nearly any burger will satisfy that craving, the most indulgent options are loaded with high-calorie toppings like creamy sauces, fried add-ons, and fatty bacon, making them calorie bombs in disguise. Doing a little research before you order can help you steer clear of the worst offenders and choose a better option that won't derail your eating goals.

To avoid fast-food burgers that can pack on the pounds, it's essential to watch out for three key nutrients: calories, saturated fat, and sodium.

  • Calories: The average American consumes 2,000 calories per day. This means that if you're eating three to four times a day, each meal should be around 500-600 calories. Some of the unhealthiest fast-food burgers may contain twice that amount.
  • Saturated fat: A diet high in saturated fat has been strongly linked to an increased risk of cardiovascular disease. Based on a 2,000-calorie diet, you want no more than 22 grams—or 10% of your total daily calories—to come from saturated fat.
  • Sodium: Lastly, sodium is a nutrient that all Americans overconsume. The limit is 1 teaspoon of salt, which is the equivalent of 2,300 milligrams of sodium. Fast food joints are notorious for having tons of sodium in dishes—so finding a menu item with less sodium is a win.

Below, we've highlighted 7 of the unhealthiest fast-food burgers, plus 7 healthier alternatives identified by registered dietitians. Keep this list in mind next time you're on the go and looking for a better burger choice. For more, don't miss 15 Healthiest Fast Food Burgers, According to Dietitians.
