I've been using WW online for about a month and while I haven't lost a ton of weight I can see that it is leading me that way. I find the key problem I have is not recording accurately when I graze (evening, when cooking or weekends when meals are unstuctured). Using the phone app (android for me) helps minimze that problem.

You can dothe same thing with pencil and paper, but WW gives you a number to shoot for in points, vs calories. The points values are based on a mix of factors not pure calories, and fruit and veggies are all zero. What is really interesting is when I was going to have a bag of peanuts from the snack machine and pluged the numbers in and that bag of peanuts was 10 pt or 20% of my day. Turned out even doritos would be a better choice. It can rally open your eyes as to bad choices that don't seem that way. and it can show things you might think as bad are not terrible...ie an egg mcmuffin is 5 pts

Bottom line if for me I think it will be worth it.

What you could do (WW probably doesn't like this ) is sign up for 3 months (around 60 dollars) and use it to train and focus, and then make your own decision after 3 months as to it's value for you.
