The thing with 0 point foods and WW Freestyle is they do not count the calories for the 0 point foods. I actually went back to Point Plus and so far I have had excellent progress. Tomorrow is another weigh in day. I do not pay for the program and I track it on a free app called iTrackbites. I just like this program better.
That said, stress could be a factor. Are you getting any exercise? Exercise makes a huge difference in my weight loss efforts.
