I don't know exactly. If I've had a day where I go off track a little, I make up for it in the following days by being extra good. But, I don't have many days where I go off track terribly =/
I may try to limit my syns a little more; drop it to 10 instead of 15 and see what happens then
And I'm also trying to include more speed foods into my meals than I have been previously. Let's hope it pays off this week
Of course some diets work better for some than others. Are you sure you are following it correctly ? Two pounds a week, week in week out should be possible. I don't think the syns are the problem.
Are you maybe being too harsh on yourself? Remember, your body behaves in an odd way if you drop below a thousand calories a day. It can be counterproductive as your body gets ultra efficient at extracting and storing whatever it can.
My bmi was a touch lower than yours, I could stuff my face like a squealing pig, have all my syns, healthy extras, gigantic plates of food, but I followed the superfree rule religiously, and I lost two to three pounds a week, every week.
Now it feels like it is a lot harder, but still two pounds a week.
I haven't followed your posts, so apologies, but have you done a food diary? ( and by diary, you write everything you eat or drink for a series of days)?
Your body, based on your bmr, requires 2,400 calories a day to function (assuming you have a low level of activity) . You eat less than that you lose weight, you eat more you gain weight. A pound of fat is 3,500 calories. To lose two pounds in a week you need a deficit of 7,000 calories. So everyday you need to consume a thousand below the level to stay the same (for you that's 2,400 - 1,000= 1,400), and lose two pounds.
With slimming world you don't need to count calories (the plan itself does the counting by following the rules) , but it can be useful to see where you maybe can improve your losses.
