Be careful with the Keto stix. Personally, I have never had them change color not even the slightest, but I continue to lose weight every week. If your not careful, and they don't change for you, don't get discouraged by it. From all the threads I have read here, I am not alone with them not changing. So, drink lots of water, take your vitamins & minerals, excercise and welcome to the forum. We are glad your here
