Some of the earliest evidence for the relationship between the microbiome and obesity came from studies of antibiotics and their association with weight gain in livestock, which pointed to a link between microbiome composition and weight maintenance. A 2006 study from the laboratory of the prominent researcher Jeffrey Gordon uncovered a mechanism by which some gut bacteria trigger obesity. Lead author Peter Turnbaugh and his colleagues noted that obese mice had different microbiomes than their lean littermates. The same was true of lean and obese human twins. When Gordon’s team characterized this phenomenon, they found that the microbiomes in obese mice and humans obtain more calories from food as compared to the microbiomes of their lean counterparts. In addition, when the researchers transferred the gut bacteria of an obese mouse to a germ free one, the formerly germ free mouse became obese.
