Efron , 26, said he was unable to eat solid food for six weeks which resulted in weight loss, reported Ace Showbiz.

Efron said that he slipped in a puddle of water and hit a water fountain.
"I was running through my house and I slipped and fell on my face. Let me start over, because the story starts kind of cool. I have a fountain in my house.
