Zac Efron hated gaining weight for his new movie

OHMYGOSSIP — Zac Efron hated gaining weight for his new movie. The former High School Musical hunk piled on the pounds for romantic flick The Lucky One but you would think his eat-as-much-as-can diet was some kind of torture.

“It was really hard,” says Zac who looks nothing but buff in the film.

“I was wearing different sized clothes. It was easier to lie down and stand up. I was just eating all day then going to the gym for an hour. It was even hard to breath. I was wheezing!”
