In order to maintain his healthy lifestyle, he continues to wear a calorie tracker every day. He also keeps two pictures beside his bed, one from before his weight loss and one after, reminding himself every morning and every night, "Never again."

Hoffman also continues to look for new ways to improve his personal fitness, describing himself as "a fitness dork." Earlier this year, he participated in his first triathlon. After training "like crazy," he snagged first place.

From 343 pounds to a lean 190. From not knowing how to use a treadmill to winning a triathlon. From "newbie" to "fitness dork." In a short time, Hoffman made a drastic change.

After that, he just kept going.
