How to eat foods

I have made the 1400 calorie mark the first time.  When I say that, I mean that I have barely gone over the 1400 calorie mark.  I did eat a rather huge lunch.  I have to learn that I am to eat like a queen at breakfast, eat like a princess at lunch, and eat like a pauper at dinner.  I finally realize how elitist it is, but I guess it is a way that I will lose weight.
