I've been on WW for about 14 weeks now and I'm not as enamored of the new points system as I was of the old. It seems like you must you use e-tools or the special new calculator (which you must purchase) to calculate points. But I have to say it DOES work. I'm just shy of a 20 lb weight loss. Tracking points is a pain in the butt, but I have to say the most useful thing was learning WHY I eat. It really makes you examine if you're eating out of boredom or emotional eating etc.
