I think I could set a world record for eating a 12 inch pizza with a knife and fork in the shortest amount of time (real record). I would train to beat this record by practicing consuming larger amounts of food in a bite. I would try to do this in as little bites as possible. Doing this while using a knife and fork. I would cut the pizza into about 4 pieces. And consume them with my fork. I casually consume on a daily basis with my fork.
