I agree with Circes^^^
Also, something that my Consultant mentioned last week, was that when you started losing weight you were carrying an additional 42lb - imagine carrying a rucksack with 8 bags of potatoes in it - that burns a lot more calories!
To get the last few pounds shifted, consider either more exercise, perhaps doing what you do but in a way that burns a few extra calories - walk a bit quicker, stairs not escalator etc! Or consider your portions sizes - are you still eating for the bigger you, are you eating more than you need to now that you are slimmer?
And lastly of course, you could simply increase the amount of superfree food you are eating - that should shift those last stubborn pounds!
