For as long as he can remember, 31-year-old Ryan of Lilbourn, MO, struggled with his weight.
Ryan's struggle with his weight came to a head in October 2012, when his twin brother -- who was also the same weight -- came down with congestive heart failure.
"It was kind of a wakeup call me," Ryan said, "that I needed to get my life in order."
Ryan subsequently signed up for a program that concentrates on portion control and exercise. The results were stunning; in a year and a half, he lost 350 lbs.
"It worked," he said. "It makes sense. Calories in vs. calories out -- you're going to lose weight."
Now, Ryan -- who is a band teacher at a local high school -- is showing off his stunning weight-loss to Rachael Ray and her co-host, Bob Harper.
