Hi May. There is a thread right here http://forum.lowcarber.org/t29683.html that should answer all those questions you have. I wrote it to help others thinking about trying BFL who wanted to maintain their LC WOL - I've been following a LC version of BFL for 10 weeks now and I can tell you that it can be done.

Please have a look at the thread and if you have any questions after reading it, just post them

Cheers,
Nat
