It's common to loosen your belt buckle a little after a big meal. But a new product called the Belty takes that task out of your hands.
This smart belt automatically adjusts itself throughout the day, depending on how much you've eaten and how much exercise you've done to compensate.
Inside the Belty is a collection of motors that expand and retract based on waist size — so it's also something you could buy once and keep over the years.
