     Let's face it.No one drinks diet soda for the taste.People drink diet soda in the hope that it will help

them lose weight or at least keep them from gaining it.Yet it seems to have exactly the opposite effect,

according to a new study.

     Researchers from the University of Texas said those who drank two or more diet sodas a day had

waist size increases that were six times greater than those who didn't drink diet soda."What we saw was

that the more diet sodas a person drank, the more weight they were likely to gain," said Sharon Fowler.

     The study was based on data from 474 participants in a large, ongoing research project, where the

participants were followed for nearly l0 years.

     While the findings are surprising, they also offer some explanations.

     Nutrition expert, Melanie Rogers, who works with overweight patients in New York, has found that

when patients are switched from regular to diet soda, they don't lose weight at all."We weren't seeing

weight loss necessarily, and that was confusing to us," said Rogers.

     So why would diet soda cause weight gain? No one knows for sure yet, but it could be that people

think they can eat more if they drink diet soda, and so over-compensate for the missing calories.

     A related study found some sweeteners (甜味剂) raised blood sugar levels in some mice."Data from

this and other potential studies suggest that the promotion of diet sodas and artificial sweeteners may be

risky," said Helen P.Hazuda, professor at the University of Texas's school of medicine."They may be free

of calories, but not of consequences."
