I am currently on WW, but if I didn't already have a good grounding in nutrition and fitness, I would most likely be eating all the wrong things. WW is more consumed with points rather than the quality of the points. They do not walk their talk. Examples are the WW foods they sell, they are filled with chemicals and horribly high in sodium. Having said all that, I will continue to go to the meetings and use their online access because I like the regular meetings/weigh ins/ and one on one support. So I use WW points but only in conjunction with healthy nutrition habits.
Also (as I ramble on) their recommendations for 18-22 points are 1200 and less calories. It's no wonder people are very hungry and re-gain the weight. There minimum baseline is NOT healthy.
