This is what a team of scientists from the University of Geneva in Switzerland have just shown, at least in mice. According to the conclusions of a new study, recently published in Cell, being exposed to low temperatures could contribute to a subject getting leaner, partly due to gut microbes.

Two studies led by Spanish scientists from the Spanish National Research Council (CSIC) and published in the Nature group journals Scientific Report and ISME Journal, respectively, have, for the first time, quantified and classified the effects of some disorders on our gut microbiota based on studies of the substances produced by bacteria when decomposing food molecules, the metabolites.

“You are not human, you are a walking bacterial colony,” says the Belgian researcher Jeroen Raes, from the Flanders Institute of Biology, in this video from TEDxBrussels. Raes discusses issues that go from the gut microbiota’s size to its functions,
