Jennifer Aniston was never all the way to fat. But before she made it big on "Friends," her agent told her she needed to lose weight. He had Jennifer meet with him in a leotard and tights. "He gave it to me straight," she says. "Nicest thing he ever did ... He said I wasn't getting lots of jobs 'cause I was too heavy." She swore off snacks, mayonnaise, white bread, and butter, and started Nutri System. After she lost 30 pounds, she landed the role as Rachel Green. [Rolling Stone]
