hi carorees,

So glad I found this, each time I am on the site and read the posts with the abbreviations, I was totally confused and felt so stupid, now it all makes easier reading and sense.
Thank you

I started to use RCI Day for Restricted Calorie Intake day

I dont know if i read it or made it up. Fasting day implies no food at all or maybe just water which is not what i do.

is RCI ok to use as a term?

It's probably far more accurate than using fast day but whether we can sell the idea to all the members I don't know! I'll add it to the wiki anyway!
Re: Forum wiki
24 Apr 2013, 18:22
Yes,I like the suggestion RCI Day as that describes what I do on a fast day!

...and then of course there are the abbreviations with multiple meanings...fil means something quite other than father in law to me, haha.
