From a scientific point of view (not officially, just my understanding of science) if you burn more calories than you consume you will lose weight; if you consume more calories than you burn you will gain weight and; if you consume the same number of calories than you burn you will stay the same. Therefore you must be consuming the same number of calories you are burning and there is only two ways round this: consume less calories or burn more! (Interestingly you burn more calories the less you weigh so as you lose weight you need to eat less - less calories that is, not necessarily volume!) How you do this is up to you.
As others have said, introduce more superfree foods, perhaps lower your syns by 2 or 3, but make sure you don't go below 5. Another idea might be to step up any exercise you do - if you don't exercise at all now would be a great time to start. Something simple like a walk round the block, do some star jumps in the adverts whilst watching TV, go swimming, ride a bike - anything to get moving. Finally have a big drink of water before each meal, this will fill you up and you won't eat as much (thirst can sometimes be confused with hunger). Finally remember variety is the spice of life!
Good Luck
