If you’re planning to go on a diet, or if you suffer from serious conditions like diabetes, knowing exactly what and how much you’re eating is essential.

In this day and age, we have calorie and nutritional calculators even on our smartphones, but they act only as guides, whereas Panasonic’s revolutionary new device, CaloRieco, actually analyzes the food on your plate and provides accurate information about in just a few seconds.

You’ve probably used calorie calculators before, and you know that they only offer general information. For example, a calculator will tell you the average number of calories in a burger, but it can’t tell you exactly how many calories are in the burger at your favorite fast food joint.

The same goes for nutrients like protein, carbohydrates or fats. And this is what makes the new Panasonic CaloRieco so special, it can actually give you accurate information on exactly what is on your plate.

Showcased at the recent CEATEC 2017 tech show, CaloRieco is a high-tech device that uses light reflection technology to determine the nutritional values of virtually any food and also provide accurate calorie estimates. All you have to do is stick your plate in the box-shaped device and wait between 10 and 20 seconds for it to analyze all the food on there.

Once it’s done analyzing the various ingredients in your meal, CaloRieco displays the number of calories, as well as the nutritional content on an LED display. According to Panasonic, the device is able to recognize the vast majority of foods, except soups and very dark dishes.

CaloRieco can also connect to your smartphone via an app, and send all the data about analyzed foods to your handheld, so you can access it whenever you need.

Panasonic said that its ingenious invention is aimed at dieters and diabetes sufferers, both of which make up a sizable market. Unfortunately, you’ll have to wait a bit longer to get your hands on your very own CaloRieco, as the device presented at CEATEC is just a prototype. It’s scheduled to hit the market sometime in the next few years, but the price remains a mystery.
