carbo-loading
A dietary strategy involving consuming large amounts of carbohydrate-rich food(s), such as pasta, rice, potatoes, etc., as a means of increasing stored energy in preparation for a major athletic event (e.g., a marathon). An abbreviated form of the term "carbohydrate loading." While some have questioned whether it really helps one's performance, I still swear that carbo-loading gives me an extra edge in big races.
