Pounds Lost: 114

Diet Strategies: Her diet had been so poor that her change to healthy eating shocked her body into rapid weight loss. Every 30 pounds or so, she would reward herself—say, with a piece of cake. "I don't feel like I've been on a diet, but now that I've changed my lifestyle, I am no longer hungry for food; I am now hungry for life."

Side Effects: "I am actually smaller than I was on my wedding day," she says with amazement, "which has done wonders for my marriage and our health as a family."
