3. Anne Hathaway
Before beginning work on Les Miserables, Anne Hathaway dropped 10 pounds through cleansing.
Even more remarkably, however, is that the actress lost another 15 pounds during production when she limited her food intake to two squares of oatmeal paste per day.
If you think that all these transformations are without any adverse effects, Anne is here to prove you wrong. She fell and broke her arm due to the strain that her body was subjected to.
