I'd say this works in instances other than obesity/anorexia as well. The norms of social groups easily rub off on the others. For instance, as was said, should there be a group of friends with one obese and the others slim, the obese one would possibly feel uncomfortable, and make an effort to lose weight as to not stand out as much. There's no reason why it can't work the other way around as well, though perhaps for different reasons. Among the most likely would be the already said instance of the slim one in a group of heavier people no longer feeling the need to pressure ones self into staying slim.
Most of this is achievable with a little common sense, but of course valuable time and resources had to be spent on it in order to scientifically prove it. -sighs-
