Study: Clean your house or get fat

Hate to dust? Want to stay a size 8? You better get cleaning.

So concludes a Duke University study that says house dust contains endocrine-disrupting chemicals that interfere with hormone production. The EDCs cause fat cells to mature and acquire more triglycerides, a type of body fat, and that causes weight gain.

Just 3 micrograms of dust could trigger fat production, according to Christopher Kassotis, lead researcher in the study.

The study, published in the journal Environmental Science and Technology, left room for new research on the subject.
