Kim Smith

Age: 30
From: Portland, Maine

Now: 150 lbs
Before: 210 lbs

How she did it: Inspired by watching the Ironman World Championship on TV Kim started exercising, working up to 60-90 minutes, five days a week. She ate small meals five times a day and eventually shed 60 lbs. Then, along with her husband, she scaled 19,340 feet of Mt. Kilimanjaro, something she said she never could have done if she hadn’t lost the weight.
