I tried WW and did not lose any weight. I was pretty frustrated as some of my co-workers started it and lost weight. But the more I thought about it, I eat pretty healthy most of the time and exercise quite a bit while my co-workers usually ate fast food all of the time. I need to find something that will work. I do have hypothyroidism which I am sure affects my ability to lose weight. I keep a food journal and eat anywhere from 1200 to 1600 depending upon the day. Stay away from most processed foods too. Maybe my body is happy with 150.
