Yes, I tend to agree with Charles. The Bear was brilliant, no doubt about it, but he had reading and his own experience to go by. The ZIOH folks, much as people like to hate on us, have the experience of hundreds of people to analyze and interpret.

Liver's fine if you like it (I do). And just to clarify, we don't generally "add" fat (although in the early days of ZIOH people did that). Fatty meat--just normal meat, really, not super-trimmed and super-lean--has enough fat in it.

My favorite "rule" is the last comment: Do not obsess. In the nearly six years I've been ZC, I've seen multiple times that obsession is what trips most people up. We just can't believe we're animals, and we really can manage to eat without a spreadsheet, lol.
