I’m not fat, and I love me some cheese. I’m pretty sure that most of the fat people I know eat far less variety of foods than I do, so I’m not certain that we can blame fat people for that. I’ve personally had a theory, based entirely on anecdotal evidence, for some time that being a picky eater is more likely to lead to obesity than any other factor, barring medical reasons such as a dysfunctional thyroid.
