For example, ghrelin and leptin are released from the stomach and adipose cells , respectively, into the blood stream.
Ghrelin stimulates feelings of hunger, whereas leptin stimulates feelings of satisfaction from food. Looking at leptin, the more cells present in a body, the more adipose tissues there are, and thus, the more leptin would be produced. This overproduction of leptin will cause the hypothalamus to become resistant to leptin and so, although the adipose cells are producing leptin, the body will not understand that it should stop eating.
