“Three or four hours a day of just consistent, ass-kicking hard work.” Is how Chris Pratt, star of the film 'Guardians of the Galaxy,' ditched 60 pounds in six months. Pratt, who is most known for playing Andy Dwyer in the sitcom 'Parks and Recreation,' was in the neighborhood of 300 pounds when he auditioned for the Marvel movie.
Marvel would pair Pratt with personal trainer Duffy Gaver and nutritionist Phil Goglia. Goglia revamped Pratt’s diet, hiking his caloric intake to 4,000 calories a day and adding lots and lots of water—one for every pound he weighed. “I was peeing all day long, every day. That part was a nightmare,” Pratt said.
Admittedly, Pratt had started gaining weight purposely for his Parks and Recreation character, but now he's committed to remaining ripped: “It gave me a sense of absolute control,” he said.
