Diet soft drinks bad for your waistline?

Clark's executive producer Christa recently gave up soft drinks for Lent. She had been drinking about 3 or 4 beverages a day.

A recent Purdue University study found that soft drinks with saccharine actually make you gain weight, not lose it. Researchers believe the saccharine alters your appetite and makes you want to eat more.

An older study suggested that diet sodas trick your brain and body in a bad way. While they're sweet to your palate, they don't offer any real sugar for the body to metabolize. There's a real disconnect between what your body expects and what it actually gets. That's why some people think drinking even one diet soda a day actually increases your chances of gaining weight.
