"I think not brushing your teeth sounds a little overly fanatical."
I'm being nice when I say that this is a support forum. People come here for support. People who educate themselves from others who have written about true fasting know that even one calorie CAN or MAY offset the ketosis aspect of said fasting.
Please be supportive. There are those of us out there who truly need it.
I can remember having to deal with a father-in-law (who is actually a retired preacher of all things).
He couldn't STAND the fact I was fasting. He'd get MAD at me for fasting. I'd point out that Jesus fasted, and that fasting was mentioned in the bible in various situations.
He always had to have the last word, though. He'd say to me, "It's your funeral."
It takes strength to fast; people need our support here.
