Skinny People were never FAT

With all the buzz about being skinny, which is the way it has ALWAYS been in hollywood, there is a new trend I have seen in commercials. Its using genetically skinny people to show how losing weight is easy. The one commerical that comes to mind is Special K. They have some girl on there that is probably a size 1, looking at her bathing suit, everyday, eating special K until she can fit back into it again. The thing is, she was never fat, or thick to begin with. And this is the way she looks on camera, in real life she must be a rail, twig, stick-like figure.
I have seen in person some people, who on film have been criticized for being a little thick. In person they look what I would consider a normal healthy weight. Just like magazines, the movies and film industry are putting out this impossible image for people to mimic. A normal person will not have a makeup crew, lighting crew, trainer, soft focus, etc. etc, to follow them around at all times. Yet people everyday continue to try and look like these photoshopped head shots of celebrities. I say be yourself, and as long as that isn't endangering your health, that should be good enough.
Thank you!
