Competitive eating, or speed eating, is a sport in which participants compete against each other to consume large quantities of food in a short time period. Contests are typically less than 15 minutes in length, with the person consuming the most food being declared the winner. Competitive eating is most popular in the United States and Japan, where organized professional eating contests often offer $10,000 or more in prize money. Competitive eaters are sometimes known as "gurgitators," a word used by those close to the sport and an assumed opposite of regurgitation.
