Hi Krishna,
you ask some very specific questions which unfortunately I cannot answer.
What Prof Ebringer said to his patients was really very simple, to eliminate the major sources of starch from our diet, potatos and anything made from wheatflour. From his writing it is clear he accepted that some would use the diet to come out of flare but return to a 'normal' diet afterwards. So no doubt he would have assumed the usual 3 meals a day, LSD certainly to be used during a flare, optional otherwise. If he ever gave additional advice it would have been specific to the problems of the particular patient, based on his knowledge of their medical condition.

This we prescribe though no physician . . .
Our doctors say this is no month to bleed. (Rich. II)

'Then you should say what you mean,' the March Hare went on. 'I do,' Alice hastily replied; 'at least - at least I mean what I say - that's the same thing , you know.' 'Not the same thing a bit!' said the Hatter.
