World's Best Dieter

Despite his lifelong battle with weight, Michael says he's doing well. "I'm alive and just loving life every day," he says. 

Michael says when he lost the weight the first time around, his approach to weight loss was flawed, which was why the pounds came back so quickly. "I was on a diet for 19 months, and I had hit my goal. I wanted to be less than 200 pounds," he says. "So like any person who had a goal…I won the gold medal, and the next day I didn't have to get up and train, so I relaxed. Going on a diet means someday you're going to go off a diet. You can't be on a diet your whole life. That's what I've learned."
