Forgive Doctor Joseph Chebli of Northwest Hospital if he calls his patients "losers." It's what they want to be, and the reason they've come to him.

Dr. Chebli is a bariatric surgeon - he does what's more commonly referred to as weight-loss surgery. With a less-than 2-hour operation, he can help his patients dramatically lose weight, and, more importantly, gain back their health.

How's he do it? Check out the video to see him perform a life-changing surgery.
