I'm a WW lifetime member from way back. But over the years, the weight came back on and I guess you could call me a yoyo dieter. I rejoined WW at the beginning of August. I was true to the program for about 6 weeks. I logged everything I ate in the tracking book. I attended the meetings. I tried the recipes. I discussed strategies with my WW leader.
After 6 weeks I lost about 8 pounds. It seemed to go off slow, but all of a sudden, I was fitting into some pants that I got on sale the year before and all my clothes were just a bit more comfortable to wear, ie: not so tight. I was amazed. After the first 6 weeks,i I relaxed a bit and didn't track the food in the log but I was watching what I ate and counted points in my head. I just go once a month to get weighed and I now have lost a total of 15 lbs.
On the internet, there are lots of free resources like electronic point tracking spreadsheets, ww recipes with point values etc.
So the bottom line is, it worked for me, but it comes off slowly.
I was thinking of trying to take off another 5 lbs by taking the log out and start to track again, even if it's for a month.
