I assume you mean "weight gain linked to diet soda" and I think the main thing is that it's still inconclusive. As much faith as we may have in science, I think in terms of dietary studies, most of them have not been able to control a bunch of outside variables. And the food industry also has a shitton of marketing noise to confuse the general populace.
