PRESS RELEASE - For the first time, the gut microbiota has been shown to play a pivotal role in the risk of disordered eating behaviour stemming from yo-yo dieting. Researchers from INRAE, CNRS, the University of Rennes and the Université Bourgogne Europe conducted a preclinical study showing that repeated dieting leads to binge-eating behaviour, which can be passed on directly by the microbiota. The results were published in Advanced Science.
