I read somewhere about being careful using MOUTHWASH because it can cause a PLATEAU in some people.
In my over 20 years of on and off low-carbing I have never had any problems with this. I use Listerine and Listerine Breath Strips all the time to help counter the bad breath that can accompany a low-carb WOE.
For one, you don't swallow the stuff and even if you did swallow a little, when you go from eating several hundred grams of carbs and sugars per day to about 20 or 25 per day, how can a little mouthwash cause you to stall? Again.. I use it all the time, and have never had a problem.
Thank You
