And he did it in just 14 months. By Cara Sprunk

William Guinn Jr. had a childhood dream of joining the United States Army, but there was a major barrier to entry: his weight.

Guinn decided that he wasn’t going to let the Army’s weight limit stand in his way and has lost over 90 kg’s in his quest to join the military. A major reason for his motivation was to follow in his grandparents’ footsteps, according to reports.

The married father-of-four was sworn in to the Army in Dallas earlier this month, and explained to a local news outlet that he had a revelation in February 2016, realizing he had grown tired of being overweight. He then committed to working out with trainers and hitting the gym at Planet Fitness six days a week, in order to shed weight from his 207 kg  frame. He also ate healthy foods and sought the advice of a nutritionist in order to achieve his goals.

In 14 months he shed nearly half his body weight, enough to enlist. It took incredible dedication — the outlet reports that Guinn would sometimes follows his a two-hour gym session with an hour-long run.

“It can be done and yes for those that didn[‘]t know [I was] trying to [get into the] military,” he wrote in a public post on Facebook. “[It] will be a great start for my career and to push [myself] harder than ever before. I will graduate from basic and M.I.T and start my career.”

As far as his body, he admits on Facebook, “I do see a change.”
