Well put.  I'm going to have to get more interested in fat at *some*
point.  And, yes, my last day is the 13th.  I imagine that I will need
to continue this thing beyond three weeks.

One more point.  I believe Robert implied that I might be wasting
muscle.  I don't think so.  I don't have the fatigue and presumably my
meeting daily protein requirements would not allow muscle tissue to be
used for energy.  I am burning fat -- losing 1/3 a pound a day equates
to about 1000 calories day, pretty close to my daily deficit if I'm
doing the math right.
