According to trainer Ignacio "Nacho" Beristain, former four division world champion Juan Manuel Marquez will modify his diet for the upcoming fight against Mike Alvarado, scheduled for May 17 at The Forum in Los Angeles.

Nacho reports he had a meeting with Juan Manuel, to outline the strategy for this fight, because they train differently for every opponent.

The Hall of Fame trainer said Marquez is going to change his diet, because for the fourth fight with Manny Pacquiao he worked his way all the way down to 139-pounds on the morning of the weigh-in, before coming in at 143-pounds later that day [after eating meals]. The fight with Alvarado is contracted for a catch-weight of 143.

"The strategy is completely different when facing a puncher instead of a boxer. We are going to outline a plan to deal with Alvarado, who is a very dangerous opponent. One of the things that Juan will have to do for this fight is take care of his weight. In the fight with Alvarado, we don't want to give him any advantage, and the weight is very important. So Juan has amended his diet, so he doesn't get down too low," Nacho said.
