A blood sugar level of 62 is hypoglycemic - an advanced Type II diabetic situation.  Individual readings have little meaning.  The important blood sugar reading is the a1c test which tells the amount of glucose the cells have absorbed over a three month period of time.  My last one was 5.6 - where any reading under 6.0 is "normal."  I was diagnosed Type II at least six years ago.  I am still Type II as is the person that your link points to.  That individual just doesn't know it.

I'm on a diet that limits carbos to 5 grams per meal for a maximum total of 15 per day - less than the Atkins induction diet.  It works.
