There was a guy in the Navy when I was in that had the same. They gave him three chances though but I got out in 2013 and I know when I was on my way out things seemed to be getting more strict. This puffball gained 120 pounds in his first year of being in the Navy and he had multiple people dedicate their free time to help him exercise and try to help him diet,  but his love for fast food and sody pop for him.
