Eat This, Not That! analyzed and graded 66 different chain restaurants, and came up with a list of America's Unhealthiest Restaurants. It goes to show how easy it is to underestimate the amount of calories in a seemingly simple meal. Consider your portion sizes (you'll live longer, too) and the types of ingredients before accepting a plate at face value.

Here are the restaurants that topped the charts with calories and fat content per serving. [America's Unhealthiest Restaurants, (Yahoo! Health/Men's Health)]

Denny's

Their Double Cheeseburger is one of the worst in the country with 116 grams of fat and made it to the list of worst bugers in America.

 

Chili's

From burgers to baby back ribs, Chili's serves up some of the saltiest and fattiest fare. Also on the list of worst bugers in America, their Smokehouse Bacon Triple Cheese Big Mouth Burger has 3,810 mg of sodium and 122 grams of fat.

 

 

Baskin-Robbins

Their Heath Shake was named the Worst Drink on the Planet. It's got 2310 calories and 108 grams of fat. Enough said.

 

 

Carl's Jr.

Instead of paring down and offering healthier choices, Carl's Jr. pushes on with their bigger is better motto when developing new burgers. Their Double Guacamole Bacon Burger has over 1,000 calories and 74 grams of fat (27 of it is saturated fat).

 

 

Dairy Queen

Combines the two evils with greasy, heavy foods followed by heavy ice cream concoctions. Eaters can easily spend their entire day's calories in one sitting here.

 

Ruby Tuesday

Their appetizers hover at around 1,000 calories each, and even their veggie and turkey burgers have more than 850 calories!

 

Chevy's

Their massive portions push many of their meals over 1,000 calories. Consistently high in fat and sodium, it's no wonder there is no nutritional information to be found

 

 

Romano's Macaroni Grill

Their Seared Sea Scallops Salad made it on the Worst Salads list with over 1,300 calories and 2,860 mg of sodium, and is considered an Italian grease spot when it comes to their appetizers.

 

 

On the border

Owned by the same parent company of Chili's and Romano's Macacroni Grill (both here on this list). Their appetizers have 120 grams of fat and salads have a full day's worth of sodium. Even their taco entrees have 960 calories (tacos only, rice and beans not included in that calculation).

 

Baja Fresh

Their Shrimp Burrito Dos Manos Enchilada-Style contains over 5,100 mg sodium -- more than two days' worth!
