> Guess what, those who drink diet sodas are more likely to be overweight. I guess diet sodas make you fat?
Not the best analogy - because there is some evidence that artificially sweetened beverages have fueled the obesity epidemic (by possibly overriding our typical satiation point for sweet foods).
Diet sodas are very very low calorie (some think they all are zero, but many are like 10cal per 20oz, so still negligible but not 0). Regardless, diet sodas do not make people fat. They may somehow affect other things that then increase our likelihood of eating bad things if we do not have will power, but they do not themselves make us fat
