Boxer Manny Pacquiao expends so much energy training and sparring that he has to eat up to 7,000 calories every day. Marv Dumon of Examiner.com recently spoke to Alex Ariza, Pacquiao's conditioning coach, about Manny's vast caloric intake and output:
You can't fit eight solid meals in a day. We have to supplement Manny's diet with liquid calories, and that way, he does not have to wait long in order to eat again.
Manny is burning anywhere around 1,500 calories in the morning and another 2,500 calories in the afternoon. [Pacquiao has been sparring on Tuesdays, Thursdays, and Saturdays.] So he's burning about 4,000 calories a day. Manny has to ingest up to 7,000 calories every day.
For every pound of muscle, it takes 50 calories to sustain that particular muscle.
According to Ariza, Manny currently weighs around 153 pounds. The Filipino will enter the ring on May 7 at 147, when he'll defend his WBO welterweight title against Shane Mosley. The day after the fight, he'll stop eating so much, and resume a normal diet. "You have to remember," says Ariza, "these are elite athletes who are training two to three hours per day."
Does eating so much put strain on Manny's body? "Manny's body does not get shocked from the caloric intake because of his level of output," says Ariza. "It would be extremely hard on the liver and kidneys on an average person."
