Where's my will power when it comes to that lovely white cheddar from Vermont? I also adore feta and blue cheese.

One way to get an idea of how much fat is in cheese (this works best with cheddar) is to put it in a frying pan on medium low heat, and watch how much fat gets melted out of it. You are left with a crunchy good piece of cheese with all the oil from it sitting in the pan -- after you tilt the pan somewhat. Later when the oil solidifies a bit, you can really see how much of that small piece of cheese was pure fat.

This strategy works temporarily for me. I will lay off the cheese for awhile after the obvious visual proof!
