WHY DO WE GET HUNGRY?
Our brain receives a chemical message from our digestive tract and our bloodstream that tells it that we are running low on sources. Two chemical messages are the peptides (GLP-1 + PYY) which tell the brain that we are full and to stop eating. There are two more peptides that play an important role in our eating.
First one is called ghrelin and this is the hunger hormone.
Second one is called leptin. The both of these work in opposite ways. when the stomach is full leptin is produced to stop us from eating.
When the stomach is empty ghrelin is produced to make us feel hungry.
So if you've ever wondered why we get hungry now you know.
