co-stars Natalie Portman
and Mila Kunis
both lost about 20 pounds to look like "real ballerinas." Portman, who said she ate only
"almonds and carrots," kept her ballerina-svelte frame for longer than a year, during filming and before to really get into character.
I admire her dedication to her art, but research has shown that negative effects of malnutrition, such as bone loss, immune suppression, and even brain shrinkage, can begin after just a few months of undereating. While many of the effects are reversed when the person resumes eating normally, some, like heart damage, can be lifelong. That seems like an awfully big price to pay for an Oscar.
