According to a new study, taking your shoes off at your front door could help you lose weight.
It has to do with tiny chemical particles we come in contact with every day that mess with our hormones and promote fat growth in our tissues.
The chemicals are called "obesogens." They're in everything from cleaning products and cosmetics, to processed food and even the dust floating around your house.
The study found taking your shoes off at the front door can make a big difference in how many obesogens you're exposed to, because you don't track as many into the house.
Researchers also said removing your shoes and using wooden flooring rather than carpet can help prevent these chemicals from accumulating in your home.
