Just kidding.

"The September issue of The American Journal of Clinical Nutrition just published a meta-analysis of the existing research on artificial sweeteners and weight gain. The conclusion lands in support of artificial sweeteners in the right context, specifically when they are substituted for sugar. People tend to see "modest weight loss," suggesting that low-calorie sweeteners (LCSs) indeed "may be a useful dietary tool to improve compliance with weight-loss or weight-maintenance plans."

That might seem obvious, but several studies have suggested that eating/drinking these nutritive sweeteners actually leads to weight gain. That has to do with satiety signals, effects on insulin levels, changes in the body's fluid balances, and other not-immediately-apparent downstream factors."
