One of the keys is keeping the blood sugar in balance - spacing eating out, eating smaller portions, but more frequently helps curb hunger for me. For example, when I'm working I'll take low fat yogurt, some fruit, a whole wheat turkey sandwich and maybe sliced cucumbers and carrots or other foods - Maybe at 9:00 am when I get to work, I'll have the yogurt, then at 11 maybe I'll eat half of my sandwich, and some cukes - then an hour or 2 later, I'll eat the other half of my sandwich, etc. I just eat something every couple of hours and I don't feel as hungry.
