Kirstie Drops the Pounds

In the last four months, Kirstie has lost more than 33 pounds! She says she is about halfway to her goal. But Kirstie's also thrilled about other things that have taken place during the weight loss process.

"There are things that have happened that I didn't think about happening—like, I've lost 17 1/2 percent body fat. And you lose inches and other things."
