THIS article on Cosmopolitan talks about stars starving themselves before award shows and how it's not fair to expect that of people blah blah blah.
I agree. They should be able to eat a carb the morning of an awards show. Unfortunately every TV/Radio/Magazine/Internet outlet would jump on the chance to show Julie Bowen with a food baby at the Emmys. So yeah...she skips carbs because people who take pics of her and write stories about her are crazy and would comment on how she looked if she HAD eaten those carbs.
It's a vicious cycle, I get it. But what comes first, the starvation or the media attention?
