Amy, 28, of Cincinnati, OH
Length of Engagement: 7 months
The gain: "I was a mindless snacker. Working at a shop in a mall didn't help. I would go to the food court and eat terribly."
Her OMG moment:"I received an e-mail from a website telling me I had a hundred days until my wedding. I started bawling. Even though I'd lost weight by exercising six days a week, I still hated how I looked."
