From Halloween of last year until March of this year, I lost 17lbs on Weight Watchers, however, it was around March when I became serious with weight training and stopped losing weight. I stopped WW but with the added strength training, I was able to lose inches. Weight Watchers is great for those who need to learn about portion control, however, you may run into a problem if you are an advanced exerciser, because you may need additional calories and with WW the program is structured on the point system and not calories. Since, stopping WW, I have continued on a 1300 calorie a day diet, however, my old PT told me that I need to up it to 1800 to start losing weight and get over my plateau which I have hit for 6 months now.
