I’d just like to interject for a moment. What you claim to enjoy, which you’re referring to as a cake, is in fact, the taste of a cake, or as I’ve recently taken to calling it, cake taste. Cake taste is not a cake unto itself, but rather another component of a full cake experience made complete by the weight gain, increased blood glucose, and dental effects, comprising a full junk food as defined by Wikipedia.

There really is a cake, and these people are using it, but it is not what they enjoy. Cake taste is the lie: the part of the system that makes you perceive the overall cake as good. The taste is an essential part of a junk food, but not edible by itself.
