If you haven't been able to get your rats to shed those grams after switching them to Diet Mountain Dew, know you know why. Apparently, they still think they're hungry. Saccharin just isn't satisfying. Silly rats.
Of course, some people also think this sheds some light on why there is somewhat of a correlation between diet soda consumption and obesity in humans. I imagine things are quite a bit more complicated with humans.

It would seem that this shouldn't necessarily come as a total surprise given that supposedly one of stronger observations of Dark Matter was the
Bullet Cluster where supposedly a good deal of Dark Matter and good old fashion regular matter had separated.
