A few months ago, my wife, my brother and my mother encouraged me to make the switch from soda to diet soda. Begrudgingly, I complied, and I was soon drinking 4 cans of Diet Coke a day. I acquired a taste for the stuff which I figured was okay because it doesn't have any calories. Recently, though, I weighed myself and the change didn't cause any weight loss. I was stupefied, and, apparently, I'm not alone. This exact topic has recently received much media attention.
In late June 2011, at the most recent meeting of the American Diabetes Association Special Sessions, researchers from the University of Texas San Antonio presented research suggesting that diet soft drinks may lead to weight gain in humans and diabetes mellitus in mice.
In a related study, researchers discovered that mice fed artificial sweeteners were likely to develop high blood sugar which can contribute to the development of diabetes mellitus.
