I've read in a few threads that diet soda actually contributes to weight gain. What are the reasons behind this? I'm not a huge soda drinker, but I admit I have a bottle of Diet Pepsi once a day, about 5-6 days during work so I won't get hungry from being bored.
I also drink pleeeeenty of water on top of that. So, who has an idea why diet soda would contribute?
thanks
