Yeah, it doesn't surprise me that much, but it DOES piss me off. I really wish that over processed/unnatural food just didn't exist. I'm sure it's creating a lot more damage than we realize.
I do drink diet coke; occasionally. In high school I drank it like water.

I'm with Kayia on this. I've read and heard about this phenomenon for a few years now from many different sources. It's just now coming to light.
I also don't drink diet soda (or any soda for that matter...did you know drinking soda, diet or otherwise can increase your chances of getting esphogeal cancer, esp. in men?) because the chemicals that they use to sweeten it are much more dangerous than sugar (before the FDA was pressured by Reagan to approve it, aspartame was considered a toxin, and Splenda got approved with only a handful of people being tested short term, ask me for more info). In the end, it's not the soda that is helping you lose weight, it's most likely your reduced caloric intake and increased exercise, but you might lose faster if you omit the soda. Soda also can bloat you.
Water is always the best option.

I agree Kayia that I am not losing weight because I drink diet soda but I also believe that reports of diet soda causing weight gain or hampering weight loss are over blown.
