Diet soda same as Diet drinks?

I hear the chatter over diet sodas making people fat. I really dont comprehend why but whatever..My question is.
Do all "diet" drinks pose the same risk? Like Diet snapple, Diet lipton Tea etc...

I dont drink coffee. I dont do any calorie drinks (except beer and wine or a HEED/Gatordade on a race day or Hot day working out). I dont do powders (like crystal light, etc...)
Today is day 1 of no diet sodas..But I bought some Diet Green Lipton Tea (pre made) and I drink Decaf Black Tea and the White diet Tea from Trader Joes..is this still on the "fat" lists? If I drink that or something like that everyday is it the same as diet soda?

Most diet sodas are higher in sodium but have zero sugar/cals. From what I have read, diet soda is worse than just drinking the regular kind. There's a lot of debate over the health concerns of artificial sweeteners. I don't drink any kind of soda anymore. It took a long time to like water but now that's all I drink, besides the occasional glass of milk and my coffee.

I don't know for certain but if they are sweetened with anything but stevia I would say yes. It has something to do with the way chemical sweeteners affect the brain and it's ability to recognize being full...could be wrong as it's been awhile since I read about it.

Most diet drinks have aspartame in then... I think the argument is that aspartame can actually cause one to be hungry...

I started using diet pop as a "I'm hungry, so I will have one" kinda things, and found that I was drinking WAY too much of it! Therefore, I have tried to cut back. I drink ONLY water or tea now, and then allow myself a diet pop 1 or 2 times a week for a treat (usually on the weekends). I completely plan to take this to full calorie sodas once I hit the maintaining stage though...

Sweet tasting foods trigger appetite. Fake sweet or real it does not matter.

This is what ever fast food chain alive knows, and why they give you a gallon bucket of pop. Same with movie theaters, theme parks, etc...

Artificial sweeteners also do produce an insulin response, which varies depending on your sensitivity.

And for those who state categorically that zero calorie items can not make you fat, I do not understand the rationale. Fat is moved from blood to fat cells by insulin. Foods that raise insulin levels, with or without calories, MAKE YOU FAT. Check any biology book from the discovery of insulin on.

I drink mostly water, but I have a diet Dr Pepper every once in a while. Yes, I know it isn't the best for me. Yes, I know it's full of additives and junk. BUT I have still steadily lost weight with having a diet soda 2 to 3 times a week (not every day). So I do not worry about it. I enjoy them.

I started drinking Coke Zero again after not drinking it for 7 months. I thought about it for a while and the only reason I could figure out that I stopped drinking it as that it was a form of penance for letting myself become obese. I do not know of any other reason to not drink diet soda.

It's of interest that I read that the sweeteners in diet soda "have been linked to cancer". Some of the other responses here struck me in a similar manner.

Since artificial sweeteners have been acknowledged by the FDA to be safe for human consumption (I remember the ban of sweeteners in the 70's which was followed 20 years later by a complete reversal of that ban), could the folks who are making these claims be so kind as to cite proof? Graçias.
