For as long as he can remember, 31-year-old Ryan of Lilbourn, Missouri, struggled with his weight.
"I was always a heavier kid," he said. "In my high school, I was lower 200 [lbs.] to middle-upper 200 [lbs.]. In college, I put another hundred pounds on me."
"The rest of it came after college," he said, adding he eventually got to 550 lbs.
Ryan's struggle with his weight came to a head in October 2012, when his twin brother -- who was also the same weight -- was diagnosed with congestive heart failure.
"It was kind of a wake-up call [for] 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 pounds.
"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.
Check out the incredible results in the video above.
