Hard to say but here it goes...How long are you on 1200 kcal and keeping the same weight? If it has not been months, Keep at it, and check if you are really on 1200 kcal everyday, or if some days you compensate, or if you dont eat ”invisible calories”. Increase activity level Do something you find fun because it should never be just about the x kg! Check your Macros. (AND of course I am assuming your dream weight is not the weight you had when you were 14 y).
