Some people have all the luck, don’t they? While we run miles, lift weights and jump like frogs, Keira Knightley not only enjoys her stardom but also gets to hog food to stay thin! Her mother, Sharman Macdonald broke this to the media and added that her waif figure is due to her taking after her father who has a tendency to stay thin. She also said that Knightley has to maintain a rich protein and carb diet to avoid getting reed thin. Looks like Will Knightley, a theatre actor, has given his daughter not only the gift of acting through his genes but also a boon of staying in shape! This Pirates of the Caribbean star has admitted that Anorexia runs in their family, however, she denied that she has inherited it. Well, she doesn’t need to when Daddy’s girl has daddy’s genes on her side!
