What is the optimum level of food in the digestive system of a mma fighter when he steps in the ring? I personally like my whole system to be basically empty when the bell rings. Definitely no solid foods within 36-48 hours before the fight, but thats mostly because I get nervous butterflies and an empty stomach helps me focus better plus theres no blood being used for digesting etc. I am not stating that my way is anything special, I am intersted in other points of view. EDIT to add that I am referring to the whole system, including waste.
