Fiber and weight loss?

I did not know this:

Team Beachbody:

"...a recent study has shown that eating whole fruit could be the main dietary difference between obese and overweight individuals. At the University of Southern California, researchers showed that the main difference between 52 normal-weight adults and 52 overweight and obese adults was the amount of fiber in their diets, which mainly came from fruit.

In the study, the normal-weight group consumed an average of 33 percent more fiber and 43 percent more carbohydrates than their overweight counterparts. This suggests that fiber, much more than following a low-carb or low-fat diet, is the key for weight control."

While I could not find this study exactly, here are some other studies that tie fiber intake to weight.
