I track now and then but don't really see a lot of correlation between caloires and whether or not I lose weight. I do seem to lose more weight if I am both more physically active AND more hungry, regardless of the actual calorie content. So I guess that would indicate that my hunger does work as an appropriate tool, it's just that I have to understand what it's telling me.
