'I Used WW, Food-Tracking Appss, And Les Mills Bodycombat Classes To Lose 80 Pounds' "I am using the tools I learned from WW and casually using iTrackBites." By Sarah Moss, as told to Emily Shiffer Mar 3, 2021 Courtesy My name is Sarah Moss (@nomo.yoyo), and I'm 28 years old. I am from Richmond, Virginia, and I'm an accounting specialist and MBA student. By using WW and the iTrackBites app and working out with an elliptical and Les Mills classes, I've been able to lose 80 pounds. I struggled with my weight from a young age. I went on WW (Weight Watchers) and Jenny Craig multiple times, starting at 13. Nothing I tried ever stuck though.
