The bacteria in your gut may help control when and how much you eat as study have find that 20 minutes after a meal they making proteins that influence activation of appetite-regulating neurons in the brain.

 
We now think bacteria physiologically take part in appetite regulation immediately after nutrient provision by multiplying and stimulating the release of satiety hormones from the gut, said senior study author Serguei Fetissov from University of Rouen in France.

 
We believe gut microbiota making proteins that can be present in the blood long term and modulate pathways in the brain,” Fetissov pointed out.
Fetissov and colleagues find that after 20 minutes of consuming nutrients and expanding numbers, Escherichia coli (E. coli) bacteria from the gut making different kinds of proteins than they did before their feeding.

 

Excited over this search, the study began to profile the bacterial proteins pre- and post-feeding.

 

They saw that injection of small doses of the bacterial proteins making after feeding lower food intake in both hungry and fed rats and mice.

 

Further analysis evedent that “full” bacterial proteins stimulated the release of peptide YY, a hormone associated with satiety, while “hungry” bacterial hormones did not.
