SoulDoc,
a brilliant response to your post by waterbug.
Shelton also stated that anyone who is diabetic and has been insulin-dependent for some time is advised not to fast.
"There is an equal need for experienced supervision of the Diabetic who fasts. The Diabetic may safely and profitably fast, particularly if he/she carries considerable weight. If insulin has been taken over an extended period of time, fasting is rarely recommended."
