Serotonin is a principal element when it comes to managing weight. Low level of serotonin induces a craving for carbohydrates, which in high quantities aggravates the whole situation as the excess carbohydrate turns to fat, thereby increasing the overall weight. Thus, serotonin, when used in a controlled manner, can help an individual to control his weight. One can start off with a diet rich in serotonin or can opt for serotonin supplements like 5-htp or SAM-e to utilize its effectiveness in controlling hunger. However, before consumption, it is highly advisable to consult a dietician or a physician particularly to ascertain any complications that may arise.
