Rachel McAdams tried her hand at a vegetarian lifestyle but soon realized it just wasn't for her.
"I was [a vegetarian] once, but it made me very tired," McAdams said. "I just ate pasta -- I was the most unhealthy vegetarian ever! I'd like to try it again now that I know about quinoa and bulgur. I think I'd be better the second time around."
Eva Longoria also recently admitted that her trial as a vegan was not very successful because of her lack of knowledge on food alternatives.
