I have been working out and kind of counting calories, and found this interesting.

According to the Daily Mail, researchers at the University of North Carolina found that the average American eats 570 more calories a day than they did in 1977.

The findings showed that a modern habit of constant snacking and increased portion sizes were to blame for the rise in calorie intake.

Professor Barry Popkin explained: 'It used to be you'd have three meals a day. And if you snacked, it was unsweetened tea or coffee. Nowadays, everywhere you turn there's food. If you're driving, you have a big bag of Doritos next to you while you drive.'

What's your favorite snack that may not be so good for you?
