I personally think calorie counting is a waste of time. The whole concept of dietary calories is based on an improperly applied approach to determine the "energy" store of food. It can work as a VERY general rule of thumb, but there is far too much emphasis on the calorie-in-calorie-out model.

The body doesn't burn food - it metabolizes it - and barring any unusual hormonal issues, eating the right mixture of foods should be sufficient.
