Age: 27 Starting Weight: 310 lbs. How She Did It: Working out and cutting her carb consumption
Why She Did It: She got the motivation to lose weight when her
doctor threatened to put her on high blood pressure medication if she
didn't shed some pounds, but seeing pictures of herself clinched it. "I
looked like two people," says Silva. "I was so much bigger than my whole family. I
never thought I was that size."
