Academy for Eating Disorders Releases Statement on the Dental Slim Diet Control Device

Newswise — Reston, VA, July 13, 2021 – The Medical Care Standards Committee of the Academy for Eating Disorders (AED) – a multidisciplinary group of physicians, psychiatrists, psychologists, nurse practitioners, dieticians, advocates, and researchers – has issued a position statement concerning the Dental Slim Diet Control Device:

Recently, the British Dental Journal launched findings on a brand new software designed for weight reduction, the Dental Slim Diet Control machine.[1] This equipment makes use of closed-field magnets to limit mouth opening. The seven members within the examine had been supplied a commercially obtainable extraordinarily low-calorie (800 kcals/d) liquid weight loss plan throughout machine use to advertise weight reduction. The Medical Care Standards Committee of the Academy for Eating Disorders has grave issues about the usage of this machine.

Very low-calorie liquid diets should not an innovation; an 800 kcal/day hunger weight loss plan usually results in speedy weight reduction, even with out this machine.  Rapid weight reduction can result in life threatening medical issues of extreme malnutrition in each organ system, together with however not restricted to bradycardia, hypotension, macronutrient and micronutrient deficiencies, liver illness, and refeeding syndrome. The authors did not assess for any medical issues together with laboratory and very important signal abnormalities.

Patients on this examine certainly had speedy weight reduction: the equal of 14 kilos, in 2 weeks, after which partial weight regain simply two weeks after the machine was eliminated. This is unsurprising, as weight-reduction plan is often related to repeated weight cycles of weight reduction and regain, which generally end in worsened well being outcomes and opposed cardiometabolic danger.[2] This is partly as a result of human brains reply to the notion of insufficient caloric consumption by shifting myriad physiological processes to gradual metabolism, on account of which most caloric restriction ends in quick time period weight reduction however is sort of at all times adopted by weight enhance again to baseline and sometimes greater.[3]

No psychological analysis help was included on this examine at any juncture, creating danger that use of this machine could create or perpetuate restrictive or compensatory consuming problems behaviors, in addition to different psychological issues.  The authors themselves acknowledged that “members indicated that they sometimes had discomfort and felt that life basically was much less satisfying.” Studies have proven that weight reduction makes an attempt could result in the event of consuming problems, despair, physique dissatisfaction, and maladaptive weight management behaviors.

The examine design and analyses are additionally a priority.  The two-week follow-up doesn’t permit evaluation of security or efficacy over any longer-term interval, despite the fact that the authors advocate utilizing and reusing the machine episodically over the long-term to have a number of cycles of weight reduction.  It is actually doable that this machine could trigger long-term weight achieve attributable to issues of such prescribed weight biking. 

Lastly, the AED needs to remark upon the disgrace and stigma implied on this examine. Weight is just not one thing to be cured. The potential for abuse, misuse, and psychological harm from this dental machine is of grave moral concern. We name upon our neighborhood to query the usage of not solely this machine, however of all weight reduction strategies that perpetuate weight stigma and should result in affected person hurt.
