Eh, I'm kinda skeptical education is the issue. Most people are exposed to the basic ideas of calories, most processed foods (and lately, most restaurants) have calories printed in relatively easy to find places, and with a little practice, guesstimating your calorie consumption is pretty easy even if your not exact.
It's just mentally hard to do. Like sleep, sex and other physical needs, food is wired pretty deeply in our heads, and changing our behavior in regards to it takes a lot of mental and emotional effort. And most people have a lot of other things more immediately important in their lives that take mental effort, so they eat more than they should, even if they know the consequences.
