Hear hear Glendora! I for one am cheering you on. I bet if you could get your son tested for his insulin level, it would be high all the time and so he's hungry all the time. And insulin resistant. And the high carb input does affect impulse control and emotions too.

There's a book about working with carb loving kids called "Little Sugar Addicts" that has lots of techniques and things to transform the family eating. It assumes that carb loving kids have carb loving parents, and even has what to do when dad is not on board (so common). There's a whole world of people in this situation. One caveat: last I read, the author doesn't advocate vlc, instead carb reduction including healthwholegrains, but the behavioral and biochemical talk is right on.
