Labor Day Weekend is almost here...and chances are you are going to overeat. That's no surprise. But it may surprise you just how much you overindulge. According to a new survey, the average person eats about three times more at a BBQ than they would during a normal meal.

People chow down on about 1,800 calories at a barbecue, while a typical meal at home would be about 500 to 700 calories.

And what are we eating? The top five BBQ foods are: burgers, hot dogs, salad, potato salad and coleslaw. A plate with one helping of each has around 900 calories. And most of us (61 percent according to the survey) go back for seconds.

Oh, and that's not even counting the alcohol. Have two glasses of wine or a couple of beers and that's an extra 400 calories or more.

The survey, done by a health care organization in the UK, also revealed that 59 percent of people don't worry about healthy eating at barbecues.
