Just a point - people can just as easily get wrapped up in counting calories as anything else.
And counting calories is not the same as counting WW points. When counting WW points you factor in calories, grams of fat and grams of fibre. If you are a member you are given a points counter (kind of like a slide rule) to help you figure out the points.
It's actually very easy - you just go by the nutrional information on the package of the food product (i.e. can of V8 juice) and use either the ruler or the WW points book. You get "x" number of points per day and 35 extra per week. I ignore those extra points unless I absolutely need them or have a special occasion to attend to. Then again some people use them all up every week - it's their choice.
WW prices vary from city to city so you would have to check into your local WW centre.They have discounts for seniors and students and some places have different payment plan.They frequently offer deals if you prepay - this is the route I usually go.
I am doing WW and I rarely eat prepackaged food or frozen meals or meal replacement bars as I just don't like them, and I don't drink soft drinks (diet or otherwise)

Hey, we don't even have the WW products up here in Canada - I think all we can get are the bars at meeting rooms and the WW bread and jams
I eat homecooked meals everynight, eat lot's of fresh fruit, veggies and low fat dairy- I even eat real butter and salad dressing!
I no longer eat chips or cookies on a regular basis and I never buy the "lowfat" versions of junk food either.
I eat out with friends on occasion and treat myself to gelato or dark chocolate once in a while.
The thing that I have found with WW is that it has taught me portion control and about proper nutrition and it has inspired me to cook more and I have been able to incorporate healthier choices into my life. I don't really feel like I am on a diet most of the time.
I find that WW teaches people how to eat well and encourages them to eat fresh food, whole grain products and to exercise. How you spend your points depends on you making conscious choices. At the meetings the leader and other members share information and I have learned things like meal planning, better grocery shopping techniques and how to make better choices when eating out.
I have never had them try to push meals, bars or any of their products or books on me. Like any plan your success depends on you sticking to the program.
I lost 30 lbs on WW, quit and then gained 20 lbs of it back - I have 15 to get rid of right now. My DH doesn't go to meetings but he has adopted the same eating habits as I have and he has lost weight too. I also have three friends that are on WW and like the plan and have been successful.
My best advice is to do some research before you commit $ to a plan. If you have failed to do it on your own then maybe a group support system or a weight counsellor/dietician is the way to go.
