About protein intake after completing 19 day Water Fast was my kind of 'safe' advice. In my case Chris did recommend me not to eat concentrated protein up till day 7-8 of my refeeding. I don't think he meant different kinds of vegies or even avocados. I asked him about eating nuts (hopefully I am not mistaken and I didn't keep his post) and he considered it as concentrated protein (otherwise I would have started eating them from the day one or very shortly!). As for Sky22, I was given that advice just logically. She/he went double as long as I did so, I thought, so not eating concentrated protein would be the same.
