Not all fast food is created equal—some chains go above and beyond the deep fryer. If you’ve ever looked at a double cheeseburger and thought, “how is this legal?” you’re not alone. A recent report by FOX Business breaks down which spots are dishing out the worst offenders. These 10 fast-food joints serve the most unhealthy food in America, and the numbers don’t lie. They’re greasy, over-the-top, and somehow still pulling long lines.
1. Wendy’s Baconator

This burger is more like a dare than a meal. Double beef, double cheese, and bacon stacked high—it’s not here to be subtle. The add-ons only crank up the fat and sodium, making it tough to call this anything but a heavy hitter. You’ll need a nap and a detox after finishing it.
2. McDonald’s Golden Arches

Nobody orders a Big Mac to feel light. These classics don’t hold back—big portions, big numbers, and an even bigger reputation. The fries alone are a salt bomb, and the drinks just push things over the top. Health-conscious choices exist here, but they’re not the headliners.
3. Burger King Fiery Mozzarella Fries

It’s not just the heat—it’s the pile-on of cheese, grease, and beef that makes this combo rough. The Stacker King doesn’t come to play; it shows up loaded and loud. Toss in some fried sides, and you’ve got more than a cheat meal on your hands. This one lands hard and lingers.
4. Chick-fil-A Fried Chicken

That golden crunch hides a hefty amount of oil and sodium. Even the smaller items don’t hold back once you tally the sauces and sides. It’s easy to overdo it before you realize what’s hit you. This chain proves that not all unhealthy fast-food looks messy.
5. Arby’s Chicken Slider

Don’t be fooled by the small size—these sliders pack a serious punch. Between the salt-heavy meats and thick sauces, the numbers climb fast. Add anything from the fryer and you’re staring at a full day’s worth of sodium. It’s fast, bold, and far from light.
6. KFC

The crispy skin may be what brings people in, but it’s also where all the trouble starts. Meals add up quick here, especially with the rich sides that come standard. Even the grilled items sneak in more sodium than you’d think. It’s a flavor bomb with consequences.
7. Quiznos Italian Sandwiches

These subs go big on meat, cheese, and dressings, making them way more indulgent than they look. The toaster oven might crisp it up, but it doesn’t cut the grease. Toss in a combo and you’re in deep with salt, fat, and sugar. This isn’t your average sandwich stop.
8. Five Guys Cheeseburger

Every burger here feels like a double—even the single. The fries could serve a small family, but most folks eat them solo. It’s all delicious, but also dense with fat and calories. This place doesn’t believe in small portions or restraint.
9. Pizza Hut

Crusts are packed, cheese is overflowing, and even the sauce isn’t shy. There’s no escaping the heavy load with these pies. From dough to toppings, every inch is built to hit hard. A few slices and you’ve already tapped out your sodium allowance.
10. Taco Bell’s Steak Quesadilla

Saucy, cheesy, and grilled to order, this isn’t your light option. It’s easy to forget the numbers while chasing flavor late at night. What starts as a snack can end as a sodium overload. That’s why it lands high on the list when moderation takes a back seat.
