Hi there. I did CD and Lighterlife before coming onto SW....had some nasty side effects with the milkshakes and needed to eat!
Yes, expect a gain in your first week, as suddenly you are putting bulk back into your body and it has to process it all. You have gone from starvation to feeding again and your body wants to hold on to what you are eating for as long as it can.
However, after that week (maybe 2), you will see the losses the same as everyone else. It does work Hun.
