Right missus, I'm going to put my consultants head on now ( as I was one for a few years), I have had a quick look at your food diary and on the face of it it looks fine, but because you have not really lost anything for a month, there has to be SOMETHING you are doing wrong, this diet works for anyone, so please don't think its not going to work for you.
For the next week, complete another diary but this time be specific on everything that passes your lips, so for instance don't just put 'bread roll HEXB' put which roll it is, brown, white, wholemeal? and the weight of it, do this for everything you eat or drink that is not a free food, so again don't just put 'milk', you have to put which type, how much etc.
Vary your B choices every day, so don't have the same B choice twice in a week if you can help it, this is hard but works.
Make sure you weigh and measure EVERYTHING that is not free food accurately, this is soooooooo important, and for this week try and stick to red or green (ie no mix to max, SE or EE this week, get back to basics) and try and alternate each day, red, green, red, green etc etc.
Free food, this should make up 3/4 of your food everyday, use it and fill up on it, try to eat loads of FF if possible
Finally syns - sometimes there are hidden syns in things you don't realise, we all get complacent and think we 'know' the plan and what is free etc, but things change, for instance I didn't realise lean mince wasn't free! only extra lean mince is free, sometimes you think you are being so good sticking to your syns allowance and then it turns out something you were having wasn't actually free. This is the same with healthy extras, it's so easy to tip a few more bran flakes into your bowl but it adds syns, you have to be so strict with measuring these things, I'm terrible for choc hilights out of the jar and class 3 heaped teaspoons to make a hot choc as 2 syns when it is probably more like 5 that I am having, but as I am losing at the moment it doesn't matter
What matters here is that you aren't losing after a month on the plan so I can promise you there is something somewhere in your eating plan that is not quite right, make sure you have all your HE's and syns everyday but use free food to the max, do this for the full week and see what happens, good luck!!
