Almost all of us are conscious about out body shape. Maintaining a good shape as well as healthy weight is the top priority of almost all of us. But have you ever think why some of us are thin while others are fat or obese. What guides our body weight?
Well, a new study has held the responsibility of our body weight to our genetic makeup, showing that it influences our fatness or thinness by shaping which microbes types thrive in our body.
The study was conducted by the researchers at Cornell University and King’s College London.
According to the research group, they have identified a specific but little known family of bacteria that is very heritable as well as highly common among those individuals who have low body weight.
Tim Spector, a professor at King’s College London, said, “Our findings show that specific groups of microbes living in our gut could be protective against obesity – and that their abundance is influenced by our genes.”
For the study, the researchers collected more than 1,000 fecal samples from 416 pairs of twins and sequenced the genes of microbes found in the samples.
According to the scientists, the bacteria type that was heavily influenced by host genetics was ‘Christensenellaceae’, a health-promoting bacterial family.
Members of this family were more abundant in those individuals having a low body weight than their obese counterparts, said the study.
Moreover, this microbe also protected against being over weight when studied into mice. Researchers said that the Mice that were transplanted with the microbe gained lesser weight in comparison to the untreated mice,indicating that raising the amounts of this microbe may help to prevent and also lower obesity.
Scientists believe the study’s findings may be helpful in treating weight related diseases and getting personalised probiotic therapies to cut down the risk of obesity-related problems based on any individual’s genetic make-up.
