10 Most Fattening Fast-Food Dishes Slideshow

#3 Quizno’s Tuna Melt (1,535 Calories)

Jane Bruce

This beast of a sandwich sounds innocent enough: tuna salad, cheese, and fresh veggies. But combine globs of mayonnaise with cheese and fatty fish, and you’re reeling in three meal’s worth of calories at lunch alone. Not to mention that with 110 grams of fat, this sandwich busts out twice our maximum recommended intake for an entire day.

#2 KFC Variety Big Box Meal (1,680 Calories)

Jane Bruce

If you can’t pick just one KFC favorite, the fast-food chain is now giving you the chance to eat them all at once. Their new “Big Box” meal includes drumsticks, chicken strips, popcorn chicken, two side dishes, and a biscuit. Picking the highest calorie options (potato wedges and baked beans) makes this meal a whopping 1,680 calories. You’ll need to buy the Double Down sandwich separately.

#1 Subway’s Double Meatball Marinara with Cheese (1,720 Calories)

Jane Bruce

“Eat Fresh” doesn’t necessarily mean eat well. Heaping meatballs coated in cheese and tomato sauce quickly add up to a meal that’s sky-high in calories, fat, and sodium — Subway’s sandwich artists somehow figured out how to stuff this monster with 210 percent of our recommended daily salt intake.

#10 Taco Bell Volcano Nachos (980 Calories)

Aptly named for the eruption it’ll trigger in your gut, this platter of tortilla chips, beef, beans, and cheese sauce includes a special treat: Taco Bell’s mayo-based “lava” spicy sauce, also available on specialty tacos and burritos. Special, indeed, because the concoction tacks another 200 calories onto the chain’s popular Nachos BellGrande.

#9 Wendy’s Dave’s Hot ‘N Juicy ¾ lb Burger (1,060 Calories)

Jane Bruce

A fast-food burger isn’t exactly synonymous with nutrition, but there’s a vast difference between a basic Wendy’s hamburger — weighing in at 250 calories — and the new ¾ lb “Hot ‘N Juicy” special. A bigger, buttered bun, along with three beef patties and mounds of cheese, is the equivalent of eating four standard burgers.

#8 Chipotle Steak Burrito, Fully Loaded (1,200 Calories)

Jane Bruce

At Chipotle, it’s all about choice — and some of the chain’s most popular burrito add-ons hide plenty of calories.  With jumbo, 13-inch tortillas the standard size, a Chipotle burrito counts 290 calories before a single ingredient is piled on. Add steak, sour cream, cheese, and guacamole for a burrito bomb sure to devastate your belly.

#7 Dairy Queen’s Chicken Strips with Gravy (1,370 Calories)

What could possibly make this basket of deep-fried chicken, french fries, Texas toast, and gravy even worse? The Dairy Queen chicken strip basket weighs in at 1,260 calories, 1,370 with a side of gravy! Make it a complete dinner with a DQ Chocolate Xtreme Blizzard, and you’ll have sated your progeny with upwards of 3,000 calories.

#6 Baja Fresh’s Steak Quesadillas (1,430 calories)

Jane Bruce

They might brag about a kitchen with "No freezers, can openers, or microwaves," but Baja Fresh manages to pack plenty of calories into a single 12-inch tortilla. So what's the secret recipe? Charbroiled steak, crammed between a thick layer of cheese and served with sour cream and guacamole.

#5 Pizza Hut Personal PANormous Meat Lover’s Pizza (1,470 Calories)

Jane Bruce

Marketed to the lone — and hungry — diner, this new menu item is billed as “80% bigger” than its personal pan pizza predecessor. For a mere $5, diners can enjoy 1,470 calories worth of a slather of sauce, layer of cheese, and caloric heaps of ham, sausage, pepperoni, bacon, and hamburger meat.

#4 Domino’s Chicken Carbonara Breadbowl Pasta (1,480 Calories)

The fantasy of comfort eaters everywhere: Cheesy, creamy pasta stuffed inside a bowl of freshly baked bread. So it’s hardly surprising that these pasta bowls, meant for one (web site says bread bowl is meant to be two servings, but the tin is one serving and can be up to 2,070 calories), offer up little in the way of protein, fiber, or fresh produce — and plenty of saturated fat and refined carbs (stuffed inside more refined carbs).
