(WKYT) - The Center for Science in the Public Interest has released its list of the most caloric chain restaurant meals.
This year's most extreme meal in America?
Red Robin's Monster Double Burger, served with bottomless fries, and 'killer milkshake'.
The meal clocks in at 3,500 calories, more than double a day's recommended daily intake.
In order to burn off the meal, a person would have to walk briskly for over 12 hours.
