That's the rule. When you want these muscles and bones show off, you can kiss goodbye to cakes, chips and another 'poisonous items' in the little black book of supermodel-diet. And please be a little absent-minded too when it comes to food ("Oh, I completely forget having lunch, I was just very busy shopping!", "Did I eat today? Umm, I really don't remember", "Eat? Eat what?)
I don't mean to be that sarcastic, just the extreme examples. That's why those shopping malls usually build food courts/restaurants separate from the boutiques, each got their follower, and rarely support each other.
