The high school coach said he tricked himself into thinking it was OK to live on fast food. "When you're a coach, you stop and eat at fast food places so the athletes can eat. At most places, coaches eat for free. So if it's free, then get as much as you want. This attitude made it real easy to gain weight," Cox said. Courtesy Luke Cox
A year ago, Cox weighed 400 pounds. He figured he'd live another 10 years. Courtesy Luke Cox
In June 2013, Cox won the spring 2013 Kansas City Fit Magazine weight-loss challenge. Here he poses with his coach, Ty Ratliff, his small town's elementary school gym teacher and high school football coach. Courtesy Luke Cox

His lifestyle transformation has been a positive change for the whole family. He has more energy to play with his three children, and they all go to the gym together. Courtesy Luke Cox
