>>4869391There are very few medical conditions that would result in massive weight gain in an otherwise ‘active’ person and those are very rare. It’s possible he has something, but just statistically unlikely.
My guess is it’s a combination of stress eating/over eating after getting to NXT and having trouble adjusting to their program and WWE, coupled with maybe being prescribed depression medication for any anxiety or depression he may have dealt with during that which can cause weight gain. This may have been accelerated or compounded when he realized he had a ceiling among H’s indie collection. He probably then got to a point where he stopped caring and just gave in and gave up. That is the simplest answer, so it’s what I would bet on.
