I've also heard along time ago that when you chew gum, your body thinks it is chewing food, so it preps itself for it (ie. releases insulin, increase stomach acid). This was way before I started CAD or any lowcarb diet, so if I HAVE to chew gum, it's gonna be during or after a CM, so my body actually does get food. I am not sure how my body is reacting to it, cause I've lost quite a bit of weight, so only a few days where I didn't lose.

All in all, it is a habit that you'll probably have to nix. I know it's hard, cause I am a gum "addict" too. It sucks, but for me, definitely worth it.
