Many people cannot tell the difference between hunger and thirst because the symptoms are so similar. In this way, eating even large amounts of poor quality food can increase hunger and cause the pang response in the body. Ghrelin then increases, even though the food was consumed only an hour or so beforehand.
Eating it causes a spike in insulin levels, followed by a quick drop. Junk food contains high amounts of sugar and simple carbohydrates. Falling levels of insulin cause ghrelin, and therefore hunger, levels to rise. This is because ghrelin interacts with insulin, the hormone that regulates blood sugar. Hunger pangs can happen even when the body does not need calories. Studies have shown that ghrelin increases hunger by up to 30 percent when it is administered to adults. If food is not consumed, the stomach acids begin to attack the lining of the stomach, causing hunger pains. Ghrelin signals the body to release stomach acids to digest food. The brain triggers the release of a hormone called ghrelin in response to an empty stomach or in anticipation of the next meal.
