　　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 10 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 over­compensate 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 riskyy may be free of calories，but not of consequences.”
