The book arrived this afternoon.  Read it.  Now I understand.

It is the health factor that gives you the weight loss.  The more you can
improve your health, the more weight you will lose.

It sounds like regular bacon and vinegar are definitely out.

Now my question is about salt.  The recipes in the book seem to mention
"salt to taste" so it seems that salt is not so bad.  My impression is
that some salt is perfectly fine.  The problem comes in too much salt.

Some of the zero carb, MSG free spices that I like do contain some salt
(not the primary ingredient).  I take it that a bit of this on my burgers
is fine?
