　　In the United States, more than one-third of adults are obese, obesity is difficult to treat with medication, and due to the serious side effects of weight-loss drugs, many drugs are not available. Surgery has always been an option for weight loss, but what if you can grow harmless genetically modified bacteria and replace weight loss drugs?

　　There is a group of researchers who believe that the weight loss of genetically modified bacteria can rely on weight loss. They recently tested genetically modified E. coli in mice. The weight loss effect is very significant. Compared with the mice that did not ingest the bacteria, the mice that obtained the bacteria successfully lost weight.

　　Scientists have selected a special gene from E. coli and Arabidopsis thaliana, which can remind bacteria that they release hormones when the body is obese. This hormone is transported to the brain through the blood and tells the brain to suppress appetite and stop eating. These old-fashioned treated mice ate a high-fat diet for up to 8 weeks, but less than control mice. Mice treated with genetically modified E. coli were full and weighed less than untreated mice. Not only that, it also reduces the chance of health problems such as diabetes and insulin resistance. What is clear is that these mice are still affected by the genetically modified bacteria 4-6 weeks after the experiment.

　　Could this genetically modified bacteria be the miraculous weight-loss drug we are looking for? It is sufficient to obtain the genetically modified bacteria quantitatively every month, with almost no side effects. But you need to know that mice are not humans. As a result, only time and clinical trials can communicate results.
