Jenni - I know what you mean about the weekends. I would try to use as many of the weekly points allowance as possible on the weekends along with whatever is Core. I guess it depends on what your weekend activities are, though.

I have decided that I'm going to give Core another whirl here. It seems to be the most successful plan I've done.

If anybody's interested, there's a book called "Volumetrics" by Barbara Rolls that I have heard the Core plan is largely based on. People on the WW Core message board who have read it have good things to say about it, although I haven't read the book yet myself. There are two Volumetrics books, though, and I apparently ordered the wrong one "The Volumetrics Eating Plan" which mainly has recipes and stuff like that. The other book (don't have the title offhand but by the same author) explains the actual science of Volumetrics and I'll get around to ordering that one some time.
