You may think you're taking a healthier route by substituting diet soda for regular soda, but at least some researchers say that the diet soda can be just as bad for you.

One of the more surprising claims, as reported by GetTheGloss.com, is that diet soda makes you heavier. The reason, in a nutshell, is that the fake sugars fool your metabolism into releasing insulin even though you aren't full which makes you retain fat, especially around the midsection. Diet soda is blamed for other ills, including wrinkles, premature aging, and bad teeth.
