The portion of American diets reserved for Wendy's, Burger King and the Yum Brands kingdom was smaller than it was during a 2003-06 survey, when fast-food accounted for 13% of American calories. It is an improvement that has fast-food investors scrambling, but experts contend it is still a grease-soaked bag full of bad news.
The calorie percentage is throwing everything out of whack here. Though fast food accounts for only 11% of those calories, previous studies have shown that Americans consume 270 calories worth of fast food a day -- basically a regular McDonald's hamburger and a fistful of fries.
That would put Americans at more than 2,700 calories a day, which is great if you're a 25-year-old man who's 6-foot-7 and exercises three times a week. However, for shorter, older or more lethargic, it is a recipe for a waistline disaster.
The CDC found that obese people get 13% of their calories from fast food, compared to less than 10% for those of normal weight or below. While people ages 20 through 39 get a full 15% of their calorie intake via the drive-thru window, that rises to 17% among people that age in households earning less than $30,000 a year.
By comparison, 20- to 30-somethings in households taking in more than $50,000 a year dedicated less than 14% of their calorie content to the quick and cheap.
Black Americans get 15% of their calories from fast food, compared to 11% for whites and Hispanics. Young black adults are by far the most ravenous consumers of fast food, with the CDC noting that a whopping 21% of their calories come from food ordered from illuminated menus above the counter.
