Dr. Oz has worked closely with Jillian, Jason and Frank, but he's never met James, a viewer who's been following Dr. Oz's diet plan for 18 months.
James once weighed 273 pounds, but after adopting a few of Dr. Oz's health tips, he weighs just 158 pounds! "[Dr. Oz] had said, ''The biggest fighter against fat is knowledge,'" he says. "So just by watching his show, I've changed from processed foods to one-ingredient foods." James says Dr. Oz also inspired him to quit smoking.
Sadly, heart attacks have killed all the men in James' family before their 51st birthday, but things are about to change. "My father passed at age 48 of a heart attack, and I don't want to go down that route," he says. "I want to live."
