The feeling of hunger is the sensation one feels when there is no food in the stomach.
Hunger is manifested in different forms such as malnutrition when there is an inadequate intake of food so that diseases and infections may kill the body. Under nutrition is when the person does not take in enough calories and the body becomes weak. According to the Food and Agriculture Organization, hungry mothers give birth to hungry children, who, if they live long enough, grow into hungry adults.
