Ben Dachis points us to the University of Toronto working paper (by Jean Eid, Henry G. Overman, Diego Puga and Matthew A. Turner) "Fat City: The Relationship Between Sprawl and Obesity. .. Our results indicate that current interest in changing the built envornment to counter the rise in obesity is misguided."
These results should not surprise anyone. Yet, serious people publish papers that link "urban sprawl" with obesity. Google scholar brings up almost one-thousand papers with keywords "sprawl" and "obesity." I sampled and all the ones that I found argued for a positive link.
But I did not find this stuff on the Wikipedia pseudoscience list. Well, the cited paper is a nudge in that direction.
