The explanation is that the hormone ghrelin affects the brain by making certain foods more attractive
American scientists have found that the so-called. The hunger hormone ghrelin causes people to overeat and continue to cram, even when they are full.
The results of the study were published in the Daily Mail and the Daily Telegraph.
The authors of the study found that after a period of starvation or a strong reduction in food, the body increases the synthesis of the hunger hormone ghrelin. However, it has been found that the increased synthesis of this hormone is the cause of unnecessary overeating with sweet and fatty foods that create a sense of satisfaction.
Dr. Jeffrey Sigman of Southwest Medical Center in Dallas, Texas, explains why there is always room for a delicious piece of cake or another high-calorie dessert, even when we have eaten a lot and are not hungry.
According to Sigman, the hormone of hunger affects our brains and perceptions, making certain foods more attractive and we simply cannot resist the temptation.
The results are based on a study done among experimental mice on which the role of the hormone was tested. During the experiments, well-fed mice were injected with the hormone ghrelin. These animals showed a strong preference for an empty room in which they had previously found high-fat food. The animals preferred it to the room, which they associated with receiving standard low-calorie portions.
The behavior of the mice in this experiment was similar to the desire for pleasure or reward seen in other animal experiments when cocaine or alcohol addiction was studied, the researchers said.
