Do you need to loosen your belt after a big meal? Or cut another hole after the holiday season? That's extra work and an unnecessary expenditure of calories that you've acquired into your portable fuel reserves. Instead, try a Belty: a new belt that automatically adjusts as your waist expands.
Note that it's not actually designed to help you keep eating without consequenes. The French company Emiota made Belty to help people track their fitness. Samantha Murphy Kelly writes for Mashable:
Given that the size of your waistline is a key indicator of health, the Belty — which comes equipped with small sensors, an accelerator and gyroscope — knows just how much you've been moving and whether you need to be more active.
The belt connects with an app that charts the data it collects throughout the day. It pushes out feedback and suggestions that correspond to how the belt adjusts in real time.
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.
So it's a machine that nags you about your weight. But there's more! It's also an expensive machine that nags you about your weight:
The price point is still in question, too. A Belty representative told Mashable it is a "high-end product" with likely a luxury price tag.
