Beyonce hated being skinny for her role in Dreamgirls so much that she immediately ran to put on weight as soon as she was finished. The singer had to fast for 14 days, and then eat only protein shakes to lose the weight for her role in the movie. Sky Showbiz quote her as saying about the process: “It was hard, I felt weak, but I did it. “It wasn’t healthy though. I didn’t look like me at all in the film, which was the point,” said Beyonce, 24. As soon as filming finished, however, Beyonce took charge of her body. “Immediately the next day I ate fried chicken, fried fish, French fries - anything fried - and the weight started to come on really fast and easy,” she revealed.
