That Fit Girl: Cold beer or a hot body?

Today is St. Patrick's Day, and as is tradition, many people will be hitting the pubs to enjoy a green beer and celebrate.

However, if you happen to be preparing for that summer body, beware: A lot of people don't realize how much the calorie content can vary with different styles of beer or how quickly they can add up.

If you must drink this year on St. Patrick's Day, go for the traditional Irish beers: they don't have as many calories as you would think, and because they're more full-bodied than light beers, you're less likely to drink as much.

So what would it actually take for you to burn off those green-beer calories?
