First thing I would say is where are your HEs - your milk can be your HEa (did you measure it?) but you have no HEbs and on green you should be having 2. It doesn't have to be bread - there are loads of things to choose from.
Secondly - where are you syns? You need to have at least 5 a day and preferably aim for around 10. Doesn't have to be treats it can be additions to your meals like pesto, may, curry paste, butter, oil etc.
You are not following the plan properly without these two things. And you don't do yourself any favours by missing them out.
Then I would say you are not eating much proper food!
Breakfast - a yoghurt (which one?) and fruit wouldn't keep me filled up until lunch time.
Lunch - mashed potato (homemade or shop bought?) and veggies. What about adding someone protein to your meal? There's no substance to this meal.
Dinner - Pasta and sauce - not a great choice. you would be better making your own pasta dish and having loads of veg in it like a lasagne or pasta bake, spag bol or carbonara.
If you don't mind me saying your menu is just bland - lacking in flavours, variety and interest. You're just eating stodge. You need variety and some real foods if you are to follow the plan for the long-term.
So basically you need to eat more, use your healthy extras, have more vegetables, use your syns and have lots of variety.
I'm sure you'll see the weight coming off if you follow the plan properly.
PS why not take a look at the food diary section to see what other people are eating.
