World's Best Dieter

Michael Hebranko says gastric bypass wasn't for him.
Though Michael says he considered gastric bypass surgery, it ultimately wasn't for him. When he first started focusing on weight loss, he says he was too heavy to be a candidate for the surgery. While he applauds anyone who has succeeded with gastric bypass, Michael says it wouldn't solve his illness. "Unless they're ready to do a bypass in my brain, it's not going to work," he says. "I'm never hungry in my stomach; I'm never full in my stomach. I need the bypass [in my head], where I have the disease. That's where I fight the battle every day."

This time around, Michael says he's learned not to have a specific weight loss goal. "My goal is to live," he says. "My goal is to do better every day, to be able to move a little bit more."
