Ok, just for argument's sake, lets say he is 170 as of Saturday night, when he was wearing that ***goty vest at the Diaz fight. December 5th is the weigh in. Today is the 10th. That means he has 85 days to lose 23 pounds, and he isnt exactly that fat. If he starts DIETING TODAY he can do it. But he is going to have to live on the track and the treadmill. And his calories are going to have to be carefully counted by a nutritionist each meal.
