Scientists have sparked debate with their latest invention, a ‘weight-loss device’ that has drawn comparisons to a ‘medieval torture device.’ The quest for weight loss solutions has seen its fair share of extreme measures, from risky diets to the use of medication.
One such drug, Ozempic, recently gained fame in Hollywood for its ability to suppress appetite by fooling the brain into feeling full. Unfortunately, its popularity for weight loss has caused shortages, impacting those who need it for managing type 2 diabetes.
However, an even more contentious approach to weight loss has emerged with what is being touted as the ‘world’s first weight-loss device’ that effectively locks the user’s jaw. Developed by the University of Otago in New Zealand, this device, known as DentalSlim Diet Control, employs magnets attached to the upper and lower first molars, limiting the jaw opening to just 2 millimeters and restricting the user to a liquid diet.
This invention was examined in a study featured in the British Dental Journal, published by Nature. 
In the study, participants who wore the DentalSlim device for two weeks lost an average of 14 pounds each, feeling motivated to continue their weight loss efforts afterward.
Despite these results, the public’s reception has been largely negative, with numerous people expressing their indignation on X (formerly Twitter). Comments ranged from concerns about ethical implications to sarcastic remarks about the device’s design and purpose.
One user criticized the ethical aspect, stating, “And this, kids, is why ethics needs to be taught in science. Good God, I thought medicine was past these kinds of torture devices.” Another speculated on legal repercussions: “90% sure this is in breach of a few health and war crime laws.” Humorously, another suggested, “Have you considered wiring the professors’ fingers together so they can do less of this?”
In defense of the device, Professor Paul Brunton, the lead researcher at the University of Otago’s Division of Health Sciences, claimed, “It is a non-invasive, reversible, economical and attractive alternative to surgical procedures. The fact is, there are no adverse consequences with this device.” 
The university further clarified that the DentalSlim is not intended as a permanent or quick-fix weight loss solution. Instead, it’s aimed at helping individuals who must lose weight before they can safely undergo certain surgeries. This device allows for a temporary, phased approach to weight loss, supported by dietary guidance.
