The bacteria in body may influence your weight. There’s been a lot of talk about what the bacteria in your body might be doing, but it looks like your weight might also be affected. “Researchers at Cornell University have identified a family of microbes called Christensenellaceae that appear to help people stay lean–and having an abundance of them, or not, is strongly genetic. Someday, it may be possible to have the Christensenellaceae clan adopt you, however. Mice that received transplants of the bacteria gained less weight than untreated mice eating the same diet.” The researchers wondered whether the increased use of antibiotics that kill gut bacteria indiscriminately might be contributing to obesity through this bacterial slaughter. To investigate, they looked at the bacteria in 416 pairs of fraternal versus identical twins and found that lean twins had a lot more Christensenellaceae than the obese twins. “As of now, scientists don’t know how Christensenellaceae affects human metabolism or even how it is inherited. The speculation is that human genes affect which bacteria flourish and which dwindle–much like seeds fare better or worse in different soil
