When I was doing WW a few years ago I heard about the Wendie plan and it definitely worked for me. I followed my alloted points - usually kept to the low side - every day of the week but one. For me it was Friday - Thursday was my weigh in day so I figured this was the safest day to do it. On Fridays I ate anything I wanted without counting points.
At the beginning I was almost binging on those days but amazingly it didn't take long that I could enjoy a hamburger and fries ( or whatever) and leave it at that.
I think the reason it works - at least for me - is you don't feel like you're cheating on your Wendie day. Also, you know during the rest of the week that 'Wendie Day' will come.
Just remembered, if you weigh yourself daily you will notice a gain a day or two after your Wendie Day but that gain and more will come off by the end of the week.
Good luck!
