An 8-year study on 600 Americans by MPH researchers showed that the more diet sodas a person drinks the more weight they were likely to gain.
The study started with normal weight Americans and eight years later about a third were overweight or obese.
Suprisingly, those who gained the most weight drank at least two cans of diet soda a day.
The researchers didn’t know why this relationship occurred.
Also, given the study only showed a correlation and not a cause-and-effect relationship, the researchers couldn’t say if:
* Drinking diet soda caused obesity
* Obesity caused people to drink diet soda
* Some other factor — not identified in the study — caused people to both drink diet soda and gain weight.
However, this same correlation has shown up in other studies so there probably is something real going on here.
