Well, yeah, but at least he would look 100x better than he does now! I think he has enough muscle that even if he lost size due to weight loss, he'd still have an okay physique. Shit, much better than now!
For sure,no question about it................ but his mind can`t deal with losing weight/size,plus it ain`t easy,there`s dedication involved just like in training, but dieting is harder.
Not everyone can diet to get shredded even though their genetics would enable them to look unreal if they did.
