This is why, from Joe Consumer:
Take this example: On the Border Mexican Grill and Cantina, with branches all over the United States, offers Double Stacked Club Quesadillas: a combination of a club sandwich and quesadilla, “stacked with fajita chicken, cheese, crumbled bacon, fresh avocado… sour cream… and ranch dressing.” This entree has a total of 1,860 calories, 3,440 milligrams of sodium, and 52 grams of saturated fat! Their Ranchiladas, “fajita steak topped with ranchero sauce and Jack cheese” which come with two cheese enchiladas, Mexican rice, and beans with cheese contain 1,870 calories, 3,810 milligrams of sodium, and 46 grams of saturated fat. If you add a large soda, you’re past the recommended daily allowance of calories for the day in just one meal! Without a dessert or an appetizer!Adult males should consume about 2,500 calories per day and adult females should consume 2,000 calories per day. So yeah, it's about as scary as it sounds. I ate out a lot as a kid (both fast food and restaurant food), and it showed. Anyone who knew me in high school could tell what kind of shape I was in at the time. (Round is a shape, isn't it?)
Uno Chicago Grill outdoes them, however, with an appetizer that tops 2000 calories! Pizza Skins, a combination of pizza crust, mozzarella cheese, mashed potatoes, bacon, cheese, and sour cream, has 2,050 calories! This appetizer - meant to get you ready for your main meal - also includes 3,140 milligrams of sodium and 48 grams of saturated fat. And this comes before the meal!?
I think I'm actually glad I work in the city now... I walk past several fruit stands on my way to work every day and can pick up enough fresh fruit for breakfast, lunch, and snacks. And there's like 3 Subways in walking distance too. It is all sorts of cool.
Also, the blog post I citied does give some tips for eating healthy when eating out, and refers folks to http://www.healthydiningfinder.com.
Finally, that article probably also explains this strip from Wulffmorgenthaler:
