I understand totally what is being said here.  From time to time I feel very
sorry for myself at the amount of food (total calories) it takes to maintain
my health.  I'm short in stature (5'0") and have a very effecient gut that
knows how to extract nutrients from low glycemic highly fibrous foods.  So I
eat a lot of fruits and vegetables and protein.  No grains whatever and very
little starches of any kind.  The closer I stick to this ideal the more
energy I have and the sharper the activities of my mind.  I have all kinds of
intolerances and allergies and sometimes I wonder if I'm not reacting to my
own endogenous insulin?  Just plain feel better when I keep it low as
possible.
