If you're a woman, your weight may indicate how successful you are at controlling your impulses. Specifically, obese women are more impulsive than normal weight women. They're also less likely to settle for time delays in gratification.

The study reporting this finding also looked at men, but men don't show the same level of impulsiveness, regardless of the numbers on the scale.

In the case of women, researchers say weight isn't the effect but rather the cause. It makes sense -- impulsive women are quicker to gain weight because they have more difficulty ignoring their impulses, also known as their cravings. Unfortunately, being impulsive is not something I think you can easily change. What do you think?
