I'm not sure about other countries, but I've noticed that in Australia, instead of putting the amount of Calories on the back of a food product, they show the amount of Energy in kilojoules. Maybe that is what we should start doing in America. So many Americans treat Calories as a negative, and they're too concerned with how much they're intaking. Energy, on the otherhand, has a positive ring to it. Take this box of Tim Tams for example. Each chocolate biscuit has 400 kJ of "energy". I made sure I ate 2 just in case I started running low towards the end of the afternoon.
