Body fat link to bacteria in faeces

The make-up of the bacteria found in human faeces may influence levels of dangerous fat in our bodies, say researchers from King’s College London.


Their analysis of stool samples in a study of more than 3,600 twins found evidence that some of this bacteria is inherited.

What is contained in faeces bacteria could therefore partly explain why obesity passes down through families.

The research team extracted information from study participants about the human faecal microbiome the bacteria present in faeces samples and compared these to six different measures of obesity, including body mass index (BMI) and different types of body fat.
