You are right, it is a simple math really...most of the times, its not what we are eating - its how much we are eating and it turns out every single time, more than we are spending and that's the rub...

however, we are sold on lies (including what to eat, what not to eat, but never about how we are missing the aspect of 'spending', even when we eat less, it doesn't help, because we have to spend some at least!...

I wrote an article about biggest lie about breakfast, since your interest is in this area, appreciate your comments on the subject.
