If you thought the Big Mac was big, wait until you see these beefy behemoths.

If you're going to eat a burger, go big or go home. At least that's the philosophy that many fast food lovers embrace. Of course, the biggest burger you can possibly find doesn't exist on a typical menu, but rather through the option available at many restaurant chains to concoct custom burgers with any number of patties and toppings. This DIY route allows ambitious fast food enthusiasts to create Frankensteinian burger towers with belt-breaking calorie counts. If you're wondering how out-of-hand that gets, take a look at In-n-Out's secret menu monstrosity, the 100×100 burger.

These burgers are undoubtedly impressive, but since they stay off the standard menu, their sizes and calorie counts are the stuff of legend and lore. If you're wondering where to find the biggest burgers, feast your eyes on these beefy behemoths from your favorite fast food chains, then find out how your favorite spot stacks up on our list of The 30 Most Popular Fast Food Restaurants in America.


McDonald's Double Quarter Pounder

770 calories, 45 g fat (21 g saturated fat, 2.5 g trans fat), 1,290 mg sodium, 42 g carbs (3 g fiber, 10 g sugar), 51 g protein

Despite the recent hype of the Grand Big Mac—a sized-up, limited edition version of the original being touted for its girth—the biggest burger by weight at McDonald's is actually the Double Quarter Pounder with Cheese. This menu mainstay features a gut-busting ½ pound of meat between its two buns, yet incredibly has the fewest calories of any burger on this list, coming in at 770.

Hardee's 2/3 LB. Monster Thickburger

Hardees 2/3 pound monster thickburger

1,300 calories, 90 g fat (33 g saturated fat, 4 g trans fat), 3,140 mg sodium, 53 g carbs (2 g fiber, 13 g sugar), 76 g protein

Hardee's Thickburgers could single-handedly populate their own list of "biggest burgers" with six items on the menu spilling over 1,000 calories. Yet the ⅔ LB. Monster Thickburger takes the cake at 1,300 calories. Hardee's tops off this double-decker heap of meat with four strips of bacon, three slices of American cheese and mayo, served on a baked bun. Even if you do indulge in one of these monster burgers, the 22 Best Teas for Weight Loss can help you melt the pounds right off.

1,780 calories, 108 g fat (42 g saturated fat, 0 g trans fat), 700 mg sodium, 30 g carbs (2 g fiber, 5 g sugar), 162 g protein

Wayback may be a lesser-known fast food chain, but it currently has 95 locations across the U.S. with 75 more in development. If you should happen across one of these, you're in luck—Wayback's Triple Triple burger might just be the largest burger on a major chain's standard menu. It includes nine beef patties and nine slices of American cheese with a whopping calorie count of 1,780. Luckily, you don't have to break your diet to up your protein intake; the 29 Best-Ever Proteins for Weight Loss will keep you full without filling out your waistline.

1,030 calories, 65 g fat (23 g saturated fat, 2 g trans fat), 1,880 mg sodium, 54 g carbs (3 g fiber, 12 g sugar), 58 g protein

Its neat and tidy presentation might give a customer the impression that this burger from SuperSONIC is somehow less indulgent than its competitors. But don't be fooled—each of its patties weighs a substantial quarter pound, and the total calorie count after including the bacon, cheese, and mayo is an impressive 1,030.


Checkers and Rally's Triple Buford

890 calories (all other nutrition information unavailable)

The Triple Buford at Checkers and Rally's is a mountainous triple cheeseburger, loaded with three slices of American cheese, lettuce, tomato, onions, pickles and a smattering of sauces, served on a toasted bun. The total calorie count for the Triple Buford is 890, though recent advertisements encourage adding additional patties, up to a total of nine. The real calorie count is as high as you're willing to go.


Fatburger's XXXL Burger

Nutrition information unavailable

Typically"challenge" burgers like the XXXL are restricted to secret menus or one-off food competition events, but this 1.5-pound behemoth—comprised of 3 towering ½ pound burger patties and toppings—can be ordered straight from the menu in their Los Angeles locations. Though the burger itself is pictured on the website, it is conspicuously missing from the nutritional information the company provides. For comparison, one large Fatburger clocks in at 850 calories, 41 grams of fat (13 grams of saturated fat), 2.5 grams of trans fat, 1,490 milligrams of sodium, 69 grams of carbs (4 grams of fiber, 12 grams of sugar), and 50 grams of protein.


Fuddruckers 1lb Original Burger

1,387 calories, 26 g saturated fat, 1,189 mg sodium, 72 g carbs (all other nutrition information unavailable)

The most gluttonous thing on the Fuddruckers menu also sounds the most innocent: the Original Burger. The trick here is selecting the diet-busting one pound option. The concept at Fuddruckers is to dress your own burger at their produce bar, but given that a burger and a bun alone will run you 1,387 calories, this is far from the innocuous meal that its name suggests.

Carl's Jr. ½ LB. Guacamole Bacon Thickburger

1,200 calories, 89 g fat (30 g saturated fat, 3 g trans fat), 1,990 mg sodium, 51 g carbs (4 g fiber, 12 g sugar), 46 g protein

Technically this is another Thickburger similar to those found at Hardee's—no coincidence, as they share a parent-company and logo. But because this leviathan burger can only be found at Carl's Jr. and holds the #2 highest Thickburger calorie count at 1,200, it deserves its own recognition. Plus, who can resist the twist of guacamole on a burger?


Triple Meat Whataburger

1,080 calories, 63 g fat (21 g saturated fat, 3 g trans fat), 1,720 mg sodium, 62 g carbs (4 g fiber, 12 g sugar), 65 g protein

While other massive burgers proudly tout their weight as their defining feature, the Triple Meat flies under the radar and blends in with its third- and half-pound competitors. At 1,080 calories, the total weight listed on its nutritional information is 484 grams, or just over a pound, and it's not the lettuce that's tipping the scales.


Wendy's Dave's Triple

1,090 calories, 72 g fat (30 g saturated fat, 4 g trans fat), 1,910 mg sodium,40 g carbs (3 g fiber, 9 g sugar), 71 g protein

This mammoth 1,090 calorie triple cheeseburger features three quarter pound patties, topped with standard fast food toppings like lettuce, tomato, pickles, onions, and mayo. Physically smaller, but more calorie-dense is the Wendy's Triple Baconator, which features six strips of bacon and as the website puts it,"not a single veggie to get in the way." Neither will leave you hungry. And when you're bouncing back from that burger binge, check out our Survival Guide for 20 Fast Food Joints.
