I did it a bit different, I had a SS stopping weight of 11st, this was so I knew I would never ever go above that again in my whole entire life!!!!!
Once I hit that I then went to maintainence, and have been eating "normally!" since doing the stages, I am still around 4lbs under that 11st, I havent gained or ever been above that 11st.
I had to set myself a goal that I would hit without any sabbotaging, and its worked for me, my ideal weight is probably what I am now, maybe 2 or 3lbs lower but after losing 5st, then whats 2lbs!!! As long as I never ever go above 11st again then Im happy
