I haven't started back on plan but last time I did it first week I sts'ed despite being 100% then the second week I had a nine lb loss and lost 4 stones 3 lb total over a year. Dont know why but whenever I start a diet be it slimming world or calorie counting I never loss the first week. Even when I did the cabbage soup diet (HORROR!) eveyone else was losing a stone over the seven days me nothing, nada, zip, zilch although 10lbs the following week.
P.S. I would not recommend the cabbage soup diet to anyone. EVER!
