What we need is a way to educate people about calories and consumption in a way that they can understand it... even though there are always people that will never understand it.  i am seeing this introduced at school. my younger one will have healthy eating and hidden calories in year 3 of elementary (that's age 9). i guess it's some progress. i agree that people have no idea how much they are eating. i ve seen it personally in my family. people who assume they dont eat a lot but snack on ~1000 cal while watching a movie.
