Kim,

Most people (and this is my experience) will lose some muscle too when they lose
body fat.  But if you are eating enough protein and enough overall calories, you
will lose far more fat in proportion to muscle.  So it's really nothing to worry
about.  It's just part of the process.  Likewise, when you add muscle, it is
very difficult to maintain body fat.  You'll put a little extra on, but (again,
assuming you are eating right) it won't be too much.  It is very difficult to
add muscle and lose fat at the same time, though some people can.

If you are trying to lose fat, you should just moniter your body composition
weekly, and make sure your percent body fat is decreasing.  This is CERTAINLY
possible on a high-protein, low-carb diet.  In fact, for me personally, that has
been the best way to cut body fat (I exercise and strength train too).  The
trouble Dr. Katz describes only comes up when you are losing WEIGHT but
increasing your PERCENTAGE BODY FAT.

Hope that helps,
