Hi, Denise--
I've been eating Core for exactly 1 month as of today--and I've lost 12 lbs!!
My experience has been similar to Vickie's in that I tend to stay at the same weight for over a week, and then have losses 2 or 3 days in a row, then stay again for awhile ... it's kinda weird, but who cares--as long as it comes off!
I must say I'm not stressing over the small stuff, worrying about being perfect, or any of that. I usually have something non-Core on Fridays; not planned, but it just works out that way. And it hasn't affected me at all. ('Course, Core does allow you to have, what, 35 points per WEEK of non-Core foods?) So even doing that isn't breaking the rules.
I found that the first week (making those big habit changes) is the hardest. After that, I kind of found my "groove" and have been just rolling along.
One other thing that I'm doing this time that I haven't done in any recent diet attempts in years is working out. I joined a health club right next to my office, and I've been going 4-5 times a week. When I'm there I'm usually there for close to an hour. So I'm sure that's making a big difference for me.
I wish you luck ... try to stay with it for at LEAST a few weeks to see if it's really going to work. I'm convinced--it's working for me, thank God! (I have quite a ways to go, but I'm just focused on one day at a time at this point.)
Take care--
Laurie
