The way I understand it is like pregnancy tests.... you can't read in ketosis if you aren't but you can read you aren't if you are.... lol

What essentially I have found by others reactions is...

Eat healthy and lc and take a good multivitamin (with food or you pee them out) and a fiber supplement and your losing will come whatever the color of those strips....

FYI - your urine color has nothing to do with dehydration in any normal way that I have ever seen - this is a vitamin thing.
