Research shows that the feeling of fullness you get when you eat is actually because gut bacteria is controlling your appetite. Although some of you may think your mind can control how much you eat, it’s actually your stomach that does that. More specifically, some microbes that live inside your body signal the brain when they receive enough nutrients.
About the bacteria
These microbes’ goal is actually to create a billion more of their own kind. This is why they are the ones who signal your brain that you are hungry, or that you have had enough to eat. The bacteria that plays this important part of our daily appetite is called Escherichia coli. E. coli switches the set of proteins it’s pumping out after about 20 minutes after feeding.
The experiment conducted by scientists involved rodents which were injected with tiny doses of the proteins pumped after the meal. Whether the mice where hungry or not, they didn’t want to eat anymore as the protein released into their bodies a hormone associated with satiety.
Scientists have not yet found out why exactly bacteria E.coli multiply to about one billion and then stop growing, but they are sure this happens in only 20 minutes after the meal and then appear the new proteins that induce a sort of inhibition on appetite.
Bacteria doesn’t only tell us when to stop eating
This isn’t the only research that proves bacteria influence our bodies’ behavior. For example, last year, another group of scientists found out that microbes manipulate not only how much we eat by producing satiety hormones but also influence reward pathways into the brain by producing toxins that alter our moods and hijack our taste receptors.
Researchers believe that these findings can give a better understanding of how the human body works given the influences of gut bacteria that signals our brains. Moreover, they could help find the reason behind eating disorders and finding the reason could, of course lead to finding a solution. It could explain why some people can’t eat and why others can’t stop eating.
All in all, imagine how many people can get help with their eating disorders if these findings about gut bacteria are to be further researched and developed. And this only because of tiny microbes in our stomach telling us: “you’re full”.
