Has Fasting helped any bb/bo sufferers?

I am thinking seriously about giving it a go in a couple days and wondered if anybody else has every been helped by it??? My issue is primarily bad breath.

My question is could it help clear out any kidn of toxins buildup, bacteria embalance, or a yeast problem thus reducing or getting rid of the horrible odor. I've tried literally everything else.

And I've also heard it can actually cause breath odor problems, but as far as that goes if your normal you can probably eat and then your fine again. But with a chronic severe odor problem I wonder if the cleanup would completely wipe the problem away.

Thinking of doing this for at least 10 days or more.

Any suggestions would be appreciated??
