Keri,
1) Of course I'm no expert.
2) I have tho been in deep ketosis for four months or so Doc Bernsteining. As ketosis is quite different from ketoacidosis and my BS was always low, I never measured my ketones at all (except latterly I got a Ketonix breath analyser which I now realise, embarrassingly, I don't really know what to do with. I know how to use it, but not sure what for .. embarrassing). This is partly because I was never given any ketone strips of any kind. No sign of their being used here (in Denmark).
You do produce most ketones at the beginning, as the metabolism adapts. I know nothing about what the colour levels or measurements mean, but keto-maniacs like it when their levels go up. It means they have maximum energy available for sports training. If your BS is consistently in the 5/6 range, I would think it virtually certain that this is totally benign.
I was also told by two DNs here not even to think about DKA with a BS of less than 13. And the root cause of DKA is the absence of insulin. And you are taking plenty, with those figures.
So, of course I could be wrong, but frankly it sounds totally benign. I would go for it if I were you. You will be a bionic woman in ketosis!
