4 calories= 1 gram carb. I have been slipping a LOT latly... been getting the almost to goal blue's. I have found when I do slip... I totally the carbs. then x by 4 . That is the amount of calories you want to burn within 30 minutes to 3 hours after you "slip". I found that this works great( and makes you not get that sugar high,, then sleepy mood). Keep in mind always do at least 20 minutes nonstop activity. I find this helped me a lot, also got me out of plateau, more then once.
I am struggling with the sugar alcohols. My body can not handle them, and for some reason I have been craving badly.
I have had those brownies also( twice in one week!!!) I think you might want to go to phase 1 for a few days if you find that it really effected you. But if it only effected a little then I would just stick it out.
Hope this helps
