Hi,
This subject has been discussed before (like about two years ago) when I first started.
The communion would not put you out of ketosis!
I have lost 50 pounds being on the program, I never gave it a second thought about not having the communion, and it never affected my weight loss, it is such a small piece of bread, it wouldn't have much carb to put you out of ketosis!
As of wine, I am not sure how much will it take to put you out of ketosis, but seriously, don't even think about it

I never did, I continued going to the church and having my communion without even thinking about my diet.
