In The Philosophy of Andy Warhol (From A to B and Back Again), Warhol documents his New York City Diet.
Weight isn't important the way the magazines make you think it is. I know a girl who just looks at her face in the medicine cabinet mirror and never looks below her shoulders, and she's four or five hundred pounds but she doesn't see all that, she just sees a beautiful face and therefore she thinks she's a beauty. And therefore I think she's a beauty, too, because I usually accept people on the basis of their self-images, because their self-images have more to do with the way they think than their objective-images do. Maybe she's six hundred pounds, who knows. If she doesn't care, I don't.
But if you do watch your weight, try the Andy Warhol New York City Diet: when I order in a restaurant, I order everything that I don't want, so I have a lot to play around with while everyone else eats. Then, no matter how chic the restaurant is, I insist that the waiter wrap the entire plate up like a to-go order, and after we leave the restaurant I find a little corner outside in the street to leave the plate in, because there are so many people in New York who live in the streets, with everything they own in shopping bags.
So I lose weight and stay trim, and I think that maybe one of those people will find a Grenouille dinner on the window ledge. But then, you never know, maybe they wouldn't like what I ordered as much as I didn't like it, and maybe they'd turn up their noses and look through the garbage for some half-eaten rye bread. You just never know with people. You just never know what they'll like, what you should do for them.
