Voodoo and Fraud!... ?

I'm no lawyer, but I'm trying to figure out what fraud has to do with this survey by Men's Fitness Magazine.

Houston Mayor Bill White,... called the survey "mostly voodoo and fraud."

I mean, they gathered some statistics about American cities and used them to decide which ones they felt were "fattest" and "fittest." Although it wasn't very scientific, what's so fraudulent about it? So there's a bunch of fat people in Texas. Did we need a survey to tell us that? Now Voodoo, well, it's obvious that the editor of Men's Fitness is big in black magic. Just read the survey and you'll see that it's full of voodoo.
