Given that changing from regular sugared soda to diet soda is a fantastic way of dropping your caloric intake, this is pretty discouraging news, if it pans out. (Short form: diet sodas, by providing "sweet" with "no calories" teaches the brain to ignore some of the signals it uses in other circumstances to regulate how much you eat.)

I've been hearing variations of this story for a while now. If you eat the exact things you ate before the switch I don't see the problem. I switched to diet only about 6 years ago. I'm over weight for sure but I'm not gaining. If I drank the same amount of regular as I do of diet I'd be a blimp for sure. I'm cutting out hundreds of calories a day.
Oh, I'm not saying that drinking diet isn't probably net better than drinking sugared, +Tony Brandt — but the fact that it has its own negative dietary impact is rather disappointing.
Oh I know you aren't. This is a better article by far than most of them out there. They are misleading and imply that drinking diet pop is somehow worse and that combined with the claims of aspartame causing sporadic tentacle growth I never hear the end of it from strangers on the elevator. "That stuff''ll kill ya."
"… sporadic tentacle growth." Thank you sir — that's a mouthful of Coke Zero all over my screen.
