Keto sticks was discouraging to me. I have never been in the purple yet. I was using them continuously thinking that I would eventually see purple. I think that if you keep your body hydrated like you should, by drinking plenty of water , you may never see purple. I was using the keto sticks and could not figure out why I was not in ketosis yet. I quit using them. I was also weighing myself everyday and that was discouraging. I have not weighed for 2 weeks but I can tell that my clothes fit better. I am afraid that if I get on the scales that I will only be discouraged again.
