According to a new Canadian study, being a bit overweight may add a few years to your life.

Researchers looked at more than 10,000 adults in Canada over a 12-year period. As expected, the study found that people who are significantly underweight or obese tend to die earlier than people of normal weight.

But surprisingly, it also found that people who are mildly overweight live longer, on average, than people whose weight is considered normal.

Why? The study doesn't say. And other studies have come to different conclusions. A 2008 European study found that carrying extra belly fat increases the risk or early death. And while it was once widely accepted that being obese shaves years off your life, that's no longer a certainty.
