>Very misleading. In fact, the author of this study is a behavioral neurologist, hence studying human behavior relating to diet drinks rather than diet drinks themselves. Drink as much diet soda as you like, if the rest of your diet is healthy then you're fine.

Only people are not Vulcans -- to seperate such things as easy as you put it. For example, who told you that, from a behavioral standpoint, drinking diet soda and having a healthy diet are compatible?

If anything, the "behavioral neurologist" suggests otherwise.

Your idea that diet soda is totally OK (which btw, needs a citation), is based on the premise that people can easily do the healthy diet and still consume diet soda. Which might be true for some, but clearly does not work for most -- not because it is physically impossible, but because other factors (e.g behavioral, psychological, etc) are also into play. Dismissing those as irrelevant does a huge disservice to studying the matter.
