I was on 21 day fix for almost a year, exercised hard daily and lived on protein and veges. No thyroid, hormone issues, etc. I cried because I could not lose lbs. I started ww green in Feb and down 17 lbs. I was shocked. I now eat carbs, fruit, chocolate, wine, and as long as I track and measure everything, I lose. I am still in shock. I believe I needed to actually eat more, cut back on protein and that is what is finally working for me. My mind kept screaming you cant eat that it's bad, and was scared I'd gain weight, but I weighed daily and it keeps going down. It's still hard to believe but it truly does work.
