No one suggested causality, but the correlation between diet soda intake and obesity is much stronger in the medical literature than you are suggesting. We’ve done the research, but a Google scholar search of “diet soda + obesity” would show you many peer-reviewed journal articles that show the correlation is strong across a variety of populations – teens, diabetics,”healthy” women – and that’s reason enough for us to recommend against them. Of course, that’s only one reason – diet sodas are supernormally stimulating, nutritionally barren and contain a host of additives and ingredients that detract from your health.

And, for the record, the Stevia they add to processed foods and drinks is nothing close to “natural.”

So we don’t care if you like it or not – across the board, all sodas (diet or otherwise) are a poor choice. And frankly, that’s just common sense – you don’t really need a study to tell you that, do you?

Best,

No one’s ever been able to prove anything else in humans. Just point to the correlation, which has an obvious explanation that everyone is overlooking.

I’m NOT saying “drink diet soda”–if you don’t like it, don’t drink it. If you *do* like it, it’s worthwhile to avoid aspartame, and there are good alternatives sweetened with stevia now. But there’s no possible explanation other than wishful thinking that would show diet soda *causes* obesity.
