Perhaps this was already stated on this thread, but Hunt is coming off an injury layoff and major surgeries, meaning that he wasn't training/dieting for many months since his last fight. It's very commendable that he wants to get back into action, especially against a tough opponent.
I'm hoping that Zuffa will extend to him the same help they offered to Cyborg, in providing Dolce's services for nutrition/weight loss advice. I'm not a fan of Dolce's methods, but I think that Hunt could benefit from someone (maybe not necessarily Dolce) from outside his camp, pushing him to get back into fighting shape.
