Hi
I've been using mfp for 8 months now. Aim for 1200 cal but varies from 1000-1500 (for the most part, except very occasional treat days like once a month).
I've done well and lost almost 3 stone which I know is fantastic. I've also joined the gym and try to go 3 times a week plus an active job.
I need to lose prob another 3 stone 
Problem is, lately (past 2 months) my weight just static!
Don't know where I'm going wrong. I try to eat well, usually have :
Porridge/cereal for breakfast
Chicken wrap/salad or jacket sweet potato
Evening meal homemade foods like pasta, chicken and sp wedges, sausage and bean casserole etc
I have a protein shake if exercising to keep protein intake up.
I do like sweet things but I try to limit these to a small piece of chocolate a day if I've enough cal left
Any advice welcome
