Do dieticians have a concern? We may not be there yet, but Lumen, a smart health smart health connected object the size of a lighter, promises to help eat better without any analysis other than that of the user's breath.

smart health connected objects helping nutrition are not new. They range from the largest (such as smart health connected refrigerators which offer menus based on what they contain and the food uses of their owners) to the smallest, like the NutriBullet smart health connected blender. Lumen arrives on a hypercompetitive market, but by adopting a slightly different approach: the idea is to analyze the user's metabolism (i.e. all the chemical reactions that take place in his body) to let her know what her next meal might be.

Lumen basically bases its suggestions on the level of carbon dioxide present in the exhaled air. Very schematically, if this rate is low, the individual is burning fat; if he is strong, he consumes his sugar reserve. The idea is therefore to offer dishes based on the results obtained in order to provide the body with the type of nutrients it needs at instant T.

Obviously, these recommendations do not happen overnight. It takes a certain amount of time to calibrate, with many measurements, so that the Lumen can adapt the recommendations to the body size of the user, his lifestyle, his sleep cycles and many other parameters.

When Lumen is ready, it is enough to blow at a regular rate, for 10 s for the sensors to measure the level of carbon dioxide and the magic works. The information is transmitted to the app available on iOS and Android, which is mandatory to take full advantage of the device. In addition to the recommendations concerning meals, the designers of Lumen promise regular and precise monitoring of the user's metabolism, and therefore of his general state of health. He will thus be given some advice on the physical exercises to perform, a particular diet to follow. Lumen can even suggest a few tips for sleeping better.

Known technology

Metabolic measures based on CO2 rejection have been known for some time and have been used effectively. But until now, exams had to take place in the hospital with much larger machinery than Lumen. This miniaturization makes it possible to free oneself from these constraints and to offer better monitoring to the user, more comfortable and less restrictive, day after day.

The Lumen is – for the moment – not sold in major brands, and you have to go to the manufacturer's site and pay $ 349 to get it.
