Slimming down for a role in a movie by the celebrities has been a regular practice. Quite many names in the list of the actresses are there who have been asked and have hit the target hard for loosing weight for their particular roles in the movies. Loosing weight in such a short notice as in weeks is never so easy and the Hollywood stars leave no stone unturned in achieving their goals. Take Anne Hathaway as an instance which is on a 500-calorie-per-day deprivation diet for fitting the shoes for her role in the film adaptation of Les Misérables. She has been asked to loose 16 lbs in just 3 weeks and that surely is a challenge! Some other roles that she has in her hand to keep her trimmed and slim are The Devil Wears Prada and The Dark Knight Rises.
