Actually I am not incorrect. ONE of the reasons the stix COULD be purple is that you are dehydrated. The ketones will be more concentrated in your urine if you are dehydrated, I assure you. That is one of the reasons you need to drink plenty of water eating lowcarb. The presence of ketones in your blood stream makes your kidneys work harder. Drinking lots of water helps flush them out and dilutes them a bit.
