Don Kardong once said that "Without ice cream, there would be darkness and chaos". No matter what you eat, you always have that extra space for dessert. It is like a reserve in your stomach that automatically switches on, when the time comes for having desert after any meal. Now a study brings forward some explanation as to why people always have space for ice-cream even though they cannot eat food.

Researchers at the University of Naples in Italy have cited this experience as pleasurable eating or hedonic hunger. It is a person's desire to eat for pleasure and to savor the taste rather than to eat just to restore the body's energy needs.

Lead researcher of the study, Dr. Palmiero Monteleone explained, "Desiring and eating a piece of cake even after a satiating meal is consumption driven by pleasure and not by energy deprivation". We often eat food to restore our energy needs. But when we eat for pleasure, then the body releases some chemicals that stimulate overeating. However, the reason behind physiological process is very mystifying but it is likely that there are chemical compounds such as 2-arachidonoylglycerol (2-AG) that could be linked to this excessive eating.
