I don't know how many carbs are in ginger and cinnamon but when I did this the first time I was having lots of herbs and spices and things thinking that they were carb free or low carb and then when I started gaining weight I looked into it and I found out that some of them were quite high carb, it was only a few here and there but over the course of a day it added up and put me way over my allowance.
Now I have to be really careful about what I add to my food :-(
