I had great success with Weight Watchers when I signed up in August of 2008. I did what they told me, wrote down what I ate, kept track of my points, went to meetings, weighed in regularly and lost weight. I reached my goal in 5 months, became a lifetime member, continued to weigh in and ate moderately.
I have kept the weight off for 2 1/2 years. Mostly. For some reason that doesn't make sense to me now, I ate with reckless abandon during the holidays, stopped weighing in, and certainly didn't write anything down. So Surprise! I've added a few pounds back on. I vowed I would NEVER go back up the scale, so I am back to weighing in, going to meetings and keeping track...because IT WORKS!!! I love the online option for tracking points, it costs a little, but I just replaced the cost of candy and junk food and it's even. It was not hard to get back in the groove and the scales are already reflecting the change!!
I recommend their program to everyone! It does cost money, but I have learned so much and it is the price I had to pay to figure it out. Now I'm learning the new Points plus program, seems to make sense.
