1) You do not really want the darkest purple reading as that could be signaling dehydration. Darker does not necessarily mean better at this point

2) Not sure. Perhaps someone else could help out on this one.

3) The purpose of induction is to break the addiction to sweets and to detox your system. I know many will say sugar free jello, with home made whipped cream topping is okay. But if you can go without it for 2 weeks do try. It would be much better as artificial sweeteners have been known to trigger insulin releases in some individuals. After induction you can start introducing berries into the diet
