A research team led by Zhao Liping，a professor in Shanghai，has identified a precise link between a particular kind of bacteria and unusual weight gain. “The endotoxin(内毒素) released by the bacterium can activate(激活) a gene that helps produce fat.And it also deactivates a gene that consumes fat，” Zhao says. Scientists have long believed that microscopic organisms in the gut microbiota，may play a very important role in weight gain，but they had never been able to prove it. In 2004，American microbiologist Jeffrey Gordon and his colleagues discovered a general link between obesity and gut microbiota in mice. While a link was believed to exist，proving it was another matter. “The list of diseases that they may play a role in is just growing and growing，” says Lita Proctor，director of the US National Institutes of Health.“But the problem is that we're only able to look at associations and aren't yet able to conduct causeandeffect studies.” In the clinical study，researchers found a growth of too much endotoxinproducing bacteria，leading to 35 percent of the gut bacteria，in an obese patient whose initial weight was 175 kg. Based on this information，researchers tried to cure the patient by feeding him a specialized nutritional liquid food to decrease the bacteria in his guts to ignorable amounts. After 23 weeks，the patient lost 51.4 kg，with his fatty liver disease having almost disappeared. 1．We diet strictly after the yearend overeating because______________________________.
