I started WW about a year ago and have dropped about 50 lbs. I went to "meetings" on-line, and frequented a forum there called GOAD (Guys on a Diet). I remember talking to IMACflyr there (My handle was O'sidePonsone)
Their mantra "diets don't work" is very telling of the strength of their approach. I was not completely satisfied with the points system, though. The beauty of it is that it simplifies planning your meals. The weakness I found was that it didn't track things specific to my situation, like sodium intake. I started my own Excel spreadsheet that tracks sodium, and also displays the %calories from fat-carb-protien. It also tracks what %of carb is sugar (I manage to keep it under 25%), and what %fat is saturated. I do some very detailed label reading.
Last December I went off WW to focus on calorie counting on my own. I miss the forums a little, but not the way they were set up, where threads were allowed to die unless restarted on a daily basis, no PM's, etc.
(OT My WW username contained the word Ponsone <in Spanish it is spelled ponson> It is a conjugate of the word pansa, which is gut, or belly in English. Adding the superlative suffix "on", it becomes "tubby", or "fatso")
