I haven't seen an official explanation.So doe anyone know why he intentionally put on weight? He just wanted to be big?
But there are two possible reasons:
1. He is trying this as a new strategy for getting more views, fans.
2. He is just letting himself go.
I'll go with number 2. Let's be honest being ripped takes a lot of work, energy and dedication; if you are not 100% on it, it just becomes tiring.
