Luke Cox weighed more than 415 pounds this time last year. The basketball coach and social studies teacher has struggled with his weight since college.
"I was probably well over 6,000 calories a day," Cox said.
In a normal day, Cox said he consumed 2,000 calories just in soda.
Doctors told him for years he needed to lose weight, but it was his family that ultimately made the news hit home.
"I remember getting tickets for my wife a couple years ago to go to the Nutcracker," Cox said. "I couldn't sit down in the seats. It really effected me and it was tough. I knew that I had to change."
So with the help of a trainer and a weight loss program in Kansas City, Cox made the biggest decision of his life.
"The first thing I started doing was I tapered back my soda intake," he said.
Cox has lost nearly 120 pounds since March without the help of surgery.
"He has a lot more energy now that he has lost all his weight," fellow basketball coach Joe Unternahrer said.
"When you go through something like this you realize how important family is. Now it's more about living how I always wanted to be a dad," Cox said.
And with Christmas approaching, Cox said he will need to get some new clothes.
At 280 pounds, he is just 20 pounds from his goal weight.
