Introducing Belty, the Belt That Knows When You've Eaten Too Much

Belty, a new “smart belt” introduced at CES, is designed to automatically adjust itself based on how much you’ve eaten and exercised.

We’ve all been there after a big dinner: Your belly strains against the waistline of your slacks, in search of a little more space. Slowly, surreptitiously, you reach down and loosen your belt, one notch, maybe two, hoping to bring your meal-swollen midsection a bit of relief without attracting the notice of your fellow diners.

A new product introduced over the weekend at CES in Las Vegas aims to change that scenario: Belty, the smart belt, is designed to automatically adjust itself based on how much you’ve eaten and exercised.

Belty, from the French startup Emiota, is designed to help in other ways too. It’s equipped with sensors that track your overall health and fitness via cues from your abdomen. If it deems your inactivity to be excessive, it will send you an alert to prompt you to get off your duff and get moving, and it will also connect to a smartphone app that offers you real-time fitness data.

The high-tech accessory’s makers say the prototype will be produced in France by year’s end and made available first in the United States and parts of Asia. They describe it as a “high-end” luxury product.

Of course, that probably means we’ll all have to tighten our belts just to afford it!
