It required just over 12 Calories of fuel to produce one Calorie of food in 2002

From Aisthetica:

Of these, 1.6 fuel Calories were used in the agricultural sector, while 2.7 were used to process and package food. Distribution, which includes transportation, wholesale and retail outlets, and food service operations such as restaurants and catering services, used another 4.3 fuel Calories. Finally, food-related household energy use added another 3.4 Calories to the tab. This figure has been on an upward trend; it took just over 14 fuel Calories to deliver a Calorie of consumed food in 2007, and if we extrapolate this trend the US food system requires about 15 Calories of fuel to deliver a Calorie of consumed food in 2013.
