Fasting is a kind of abstinence. It is when someone does not eat or drink for some specified period of time. It is only the case if the person does so of his or her own will. It may also be that the person only eats and drinks certain kinds of food. Most often, fasting is done for religious reasons. Depending on the tradition, fasting practices may forbid or items, such as eating certain types or groups of food (e.g. meat).
