Microbes in the human gut have a role in obesity by inuencing the
human bodys ability to extract and store calories. The aim of this study was to assess if there is a correlation between change in
body weight over time and gut microbiome composition. A new study comes to the conclusion, that 

high gut microbiome diversity, high-bre intake and OTUs implicated in animal models of improved energy
metabolism are all correlated with lower term weight gain in humans independently of calorie intake and other confounders.
