Ok, I have found that email from Chris. It is just an extraction from it:
'Your plan of re-feeding seems to be fine, but I would leave out the concentrated protein (nuts) till at least day 7 or 8.
I can't do better here than quote Shelton, which is how I broke my own fasts of 25 and 30 days. A shorter fast such as yours will take less care than this.......'.
So, based on this, I have assumed that for Sky22 it would have been better to postpone eating nuts up till day 14 of refeeding. Well, 10-12 days for sure.
