The fact that this question is even being asked says alot about today's society and the horrible mindset shared about one's body image. Why should anyone be expected to have the appetite of a person plagued by anorexia, regardless of their celebrity status? As a whole, we should be more focused on teaching children good eating habits and how to make healthy lifestyle choices. I doubt this question would be asked about a 'normal' 15-year old girl seen eating at McDonald's. Go drive by your local McDonald's - I'm sure you'll see a variety of ages come and go. And *gasp* dare I suggest that they may even be eating the food they are served?
