I use them too, just for fun. Yup, a trace means you're IN! Medifast puts us in such a mild state of ketosis that the stix don't always register for many who are in ketosis, so they're not always the best gauge to determine ketosis. Also, I notice that they only turn color for me on the first morning tinkle, and not as the day progresses....even though I KNOW I'm still in ketosis. After a couple of months on MF the ketostix won't show ketosis at all.....BUT YOU'RE STILL IN if you're sticking to the plan---guaranteed! I'm into my first month back on the plan (I've done this before) and I like to see that little stick change colors for some reason.
But I'll stop when my bottle's gone since it won't register a color change later (it's because your body adapts to the mild ketogenic state and the ketones won't show up in your urine, but you'll still be in that state).
Welcome to the
Land of Ketosis where appetite disappears and bad breath reigns!!
