For her role as Fantine in Les Mis, Anne Hathaway needs to lose 15 pounds. She probably only weighs a little over 100 pounds right now so it seems pretty tough to lose 15 pounds even given a month or two, but Anne only has 15 days. According to The Daily Mirror, the time frame for her to lose the weight was condensed because of the shooting schedule, so she is eating less than 500 calories a day. I don't even know if that would do it. She is also working out several hours a day, but a pound a day when you are skinny is hard. If I starved myself and did not eat for 15 days, I could lose 15 pounds. If I worked out too and did not die, I could probably lose more than 15, but I am a big guy. Anne is skinny skinny.
