You need to check out the gapsguide.com under the printables section. She has a guide to GAPS underwhelm, which gives some steps for working your way towards the intro. There is also a step by step intro instructions there too. I think you can also look on the GAPS help yahoo group, and see under Files, and they have several things like that out.
NCM does not give a lot of instruction on intro in her book. Basically here's what you do for the beginning: Make a meat or bone broth first. Then start off with the broth, add veggies and cook until very done and tender. Turn it off, add some fresh garlic into the soup. Drink ginger tea between soup. Next step is to add in one raw egg at a time., increasing as she is doing okay with it.
I have found it very hard in the beginning especially, to keep my blood sugar up, and I was exhausted, shaky, etc, until someone said, just eat very frequently for those three days. Like literally every two hours or less if you have to. Gotta run right now but I'll b back tomorrow.
