Well, as he said on his Instagram:
"2017: diagnosed with Crohn's Disease and life turned upside down.
2018: announced as an Honoree by the Crohn's and Colitis Foundation.
It's been a short and crazy ride and it's my mission to make sure people
are aware of this disease and that, together, we fight for a cure."
As part of his regimen against Crohn's Disease and its symptoms, he
hit the gym hard, and, the results are pretty astonishing, given how
slender he had been for most of his life.
