Some restaurants seem to be competing to make you fat, according to US watchdog Center for Science in the Public Interest.

The group found that US restaurants are promoting "X-treme eating," which can easily feed customers several thousand calories in one meal without them knowing.

Some restaurants were found to have 2,000-calorie appetizers, 2,000-calorie main courses and 1,700 calorie desserts. The recommended caloric intake for women is less than 2,000.

The group calls for restaurants to list nutritional information on their menus to help alleviate the obesity problem, which plagues more than 60 million US adults.

A CPSI statement said, "Rather than compete to make their products healthier, restaurant chains are competing with each other to make their appetizers, main courses, and desserts bigger, badder, and cheesier than ever before."

"Now we see lasagna with meatballs on top; ice cream with cookies, brownies, and candy mixed in; bacon cheeseburger pizzas, buffalo-chicken-stuffed quesadillas, and other hybrid horribles that are seemingly designed to promote obesity, heart disease, and stroke."

Ruby Tuesday, Uno Chicago Grill and the Cheesecake Factory were all listed in the report as culprits of promoting "X-Treme Eating."
