You are fine with the eggs. Peanut butter is a slippery slope, as it is easy to eat more than you think with it. I'd save the peanut butter until you are more in tune with your body and at what point you are ketogenic.
I've done a form of CKD for so long that I actually feel if I'm in or out of ketosis... I can't really explain it, but I know. All the guys above had suitable answers, which is very rare considering the people on this forum.

You are doing the right thing with making sure you are eating dietary fat, you need it with zero/low carb days. You can read up on it more in Dan Duchaine's OG book Militant Underground Body Opus, or Lyle McDonald's books.
