Implants increase weight loss in mice
A genetic implant may help trigger feelings of fullness that prevent the body from wanting to overeat, according to new research.
Researchers from the Department of Biosystems Science and Engineering in Basel, Switzerland created an implant mainly from human gene components. It works by monitoring fat levels in the bloodstream. When those levels become excessive, the implant releases an appetite-suppressing hormone, which makes the person feel full.
The implant was tested on obese mice that had been fed a high-fat diet. The results showed that when the implants detected high levels of fat and released the appetite-suppressing hormone, the mice stopped eating. Researchers also found that the mice actually lost weight despite a high-fat, high-calorie diet.
Additional studies may lead to non-invasive weight-loss methods as alternatives to surgical procedures. The development of such treatments for humans, however, would likely take years, the researchers acknowledged.
