According to a study by researchers at the National Institute of Health and Medical Research (Inserm) and the University of Rouen, bacteria in the gut could regulate the amount of food we eat in producing proteins after meals which send a signal to the brain.
INSERM notes that “the current model appetite regulation involves gut hormones that signal to neurons when we are hungry or when we are satisfied. For the first time, the influence of bacterial proteins on the issuance of the intestine to the brain of signals was observed. ”
The study, published in the journal Cell Metabolism, was conducted on mice.
The work of Sergei Fetisov, principal investigator of this study show that the bacterial proteins secreted by E. coli bacteria twenty minutes after a meal, may be involved to signal satiety.
The researcher says that “it is now important to determine whether obese people have these good bacteria capable of producing proteins that act on the brain by producing the feeling of satiety.”
Moreover, “if obese people have none or not enough, there is good reason to think that we could treat with probiotics. Administered orally, probiotics act at the level of the intestine, so it would be a natural way by activation “.
