That's what I thought at first too (poking fingers), but after reading the book more carefully, you really only do that for the first 3 days to get a baseline. After that, you only test BEFORE your meals, not after, and if your BG is not below your baseline, you put off eating until it is. You can test again in 30 - 60 minutes. He says that after a while you'll get to know the difference between appetite (your BG is still above baseline) and true hunger (your BG is below baseline, indicating that all the glycogen is depleted from your liver).

And when I do eat, I try to follow Naiman's guidelines. For me, that's at least 132 g protein, no more than 65 g fat, and no more than 65 g carbs. Yesterday was an anomoly.
