Ghrelin, also known as the “hunger hormone,” is a circulatory hormone that has many functions in the body. The production and release of ghrelin occur mainly in the stomach but also in the small intestine, brain, and pancreas. Although ghrelin performs various roles in the human body, its main functions revolve around the gastrointestinal area. This part of the body includes the stomach and small intestine. Ghrelin facilitates the sensations of hunger and fullness, and it promotes fat storage. Levels of ghrelin change significantly throughout the day, increasing when a person is hungry and decreasing after eating. A person needs ghrelin in their body to maintain and regulate some vital bodily functions. However, as ghrelin plays a key role in hunger and satiety, reducing levels of ghrelin may cause people to have less appetite and, as a result, lose weight. Some research shows that ghrelin levels increase after weight loss. A person may feel hungrier than usual, leading them to eat more and possibly put on the weight that they lost. However, research highlights that changes in ghrelin levels alone are not a sufficient predictor of weight gain after weight loss. Behavioral and environmental factors may also play a part. Those who wish to reduce ghrelin levels in their body naturally may consider reducing their intake of fructose, exercising, and attempting to minimize their stress levels.
