The mythical "average" person would eat 1.5768 pounds or, for our Northern friends, 0.71522444902 kilogram of properly prepared roast turkey at a single sitting. However, if they were eating a turducken then the answer would vary somewhat from a low of 0.75989 pounds (0.34468030604 kilograms) to 2.1564 pounds (0.97812658667 kilograms). The quantity of pre-dinner drinks and deliciousness of appetizers as well as prior courses (the Lobster Bisque was to die for) would have significant impact on the above results.
