Being in ketosis isn't actually a requirement for CD to work, you know. It just helps you stick to it - it helps take away the hunger pangs, gives you the feel good factor (if you're lucky
)
So, no. 1 - don't allow ketostix to tell you whether you're doing okay or not - if you haven't eaten anything you shouldn't, it won't make any difference to your overall weight loss.
No.2 - don't rely on them to tell the truth - ketostix are notoriously unreliable. Some people never see them turn any shade of pink but still manage to lose several stones in weight.
I personally hate that people think they need to buy the things. They're an unnecesary expense, in my opinion. You know yourself if you're sticking to the diet 100%. If you're kidding yourself that so long as you stay in ketosis that it doesn't matter about the odd cheat, then frankly you're asking for trouble (this is obviously not aimed at you, JustForMe - it's aimed at other folk who might be reading this).
Besides, I think in this case those pesky sticks are definitely lying. If you haven't eaten, you'll be in ketosis for sure.
So sorry to hear you're feeling yuck. :hug99: Hope you feel better soon.
