Yesterday I purchased my 1st keto strips. I was wondering where the ideal reading should be..That is, there are five or six differant colors on the reading chart. Light pink is a 5 medium pink is 40 and a deep almost purple is 180. I'm falling between light pink 4( trace) and a darker pink which is 20 (small amount). Sorry i sound like such a moron, but the directions are very unclear. If i'm in the trace/small are, theoretically i'm in ketosis.. but should i be in more of a ketonic state to get optimal results?
