I'm not nearly as knowledgeable as many of you about the intricacies of these studies. But I do know that much too much is made of rodent studies, attempting to apply them in their entirety to humans. As Karen noted, we are exceedingly complex organisms, and Occam can keep his razor, here. The simplest explanation for a singular phenomenon is an entirely reasonable goal. For feeding studies, where, even if one one foodstuff is fed, one needs to account for both the presence of that foodstuff, and the absence of all others: it just is too confining.
