Though she is now 160 pounds lighter than she was when she underwent gastric bypass surgery, Star says having a new body hasn't totally set in. "I'm still 300 pounds in my head some days," she says.

Part of that feeling is the fear that she will disappoint her fans, Star says. "When I was a little kid and I would get chastised by my parents, I longed for a whooping instead of hearing my mother say, 'You have disappointed me,'" she says. "If I disappoint you, I feel like a failure."
