When I did a lot of testing, I found that sometimes when I came home from work and tested, I would be really quite low for me, sub 4.2. I do the cooking and I often wonder if just the act of preparing food is enough to trigger a dump as come before meal time it could be into the 5's and I hadn't eaten a thing....
Then again it might just be the natural flow....
Adjusting to a new diet can take a long time for things to settle down.
Had lamb fricassee tonight with broccoli and an avocado salad and a glass of red wine.
