The idea is simple: if you can’t open your mouth properly, you’ll eat less. From that simple thought, scientists in New Zealand developed the DentalSlim Diet Control.

The device can be mounted by dentists and uses magnetic components with locking bolts.

Thanks to the device, you can only open your mouth a few millimeters. So you can only consume liquid food.

And it worked fine for a group of test subjects. They lost an average of 6 kilos in a few weeks.

At least: the participants who persevered and did not cheat. Because some were mad about it and left the DentalSlim Diet Control prematurely. And at least one contestant cheated: he ‘drunk’ melted chocolate

Online there is a lot of criticism, as people compare the device to a medieval torture device. And participants complained that the device was difficult to use, causing discomfort with their speech. They said they felt tense and that “life in general was less satisfying”.

But for those who lose weight is a must, for example in morbid obesity, and who do not want or cannot have a stomach reduction, it seems to be a solution.
