This means that you can be "full" even on an empty stomach. Just that your bacteria are already satisfied.
A new study in France points out that intestinal bacteria Escherichia coli (E.coli) produce proteins that suppress your appetite 20 minutes after meals. They release proteins from satiety after they have enough nutrients for themselves. That is, it may be that the amount of food you eat is being controlled by the needs of a microscopic being.
The research looked at the proteins produced by E.coli in the intestines of rats. Twenty minutes after meals, they began to release different proteins than they were producing before. Counting minutes was important to the conclusions: 20 minutes is the time it takes for a person to be satisfied after eating. In one test, proteins named ClpB were isolated and injected into mice. The intention was to see how they would affect the animals' appetite. The result: Everyone ended up eating less.
The explanation for the phenomenon is that ClpB stimulates the release of the hormone Peptide YY, which is linked to the feeling of satiety. This means that when you can't even look at another piece of cake, it's not because your stomach or intestines are operating at maximum capacity. It's just that your bacteria are already satisfied.
"Our study shows that proteins from E. coli they may be involved in the same molecular pathways that are used by the body to emit the satiety signal. Now we need to know how the altered gut microbiome can affect this physiology. "One of the possible applications of novelty is treatment in obese people. And further, by better understanding this relationship of the human body to the bacteria present in it, science could unravel behaviors such as binge eating and other disorders.
