Gemma hon, if you cant continue a good week on after a successful week, with a plan as flexible and easy as sw.. how do you intend to keep that motivation when your being even more 'strict' ? - i have no idea about ww, so dont know.. but if you restrict yourself, your far more likley to want somthing more.. esp if your hungry. Personally i dont think you should switch 'diets' just for loosing and switch back to maintain, i think its ok to give somthing new a go for a week or so when you just cant shift those last lbs to target .. but i think you should fully commit to one plan.
i say this because its a long road to target (not lbs wise, emotionally) and you have to give it your all. That plan becomes a part of you and its stuck in your brain. You'l really struggle to get back into sw if you spend the rest of your journy on another plan because you just wont be used to it, and i think its just adding unneccisary pressure to yourself.
Gemma babe, its not the plan.. your just not commiting to it in the long run. I think you need to sit down with yourself and really think about why YOU can stick with it after a good week? and put into action the solutions you come up with. What your takeling right now is the 'other side' to weight loss, the emotional side to food. No plan, whether it be sw or any other will fix that.. you have to work at it.
