Congratulations on the amount that you've already lost!
Looking at your diaries, I think you're not drinking enough water, you need to be getting 1.5 - 2 litres of water in you a day.
Have breakfast, this gets your metabolism going first thing in the morning, you can't stoke a fire and expect it to keep burning without any fuel!
Have your second Healthy B option, if you fancy some chocolate - get some Kellogg's Fibre Plus (they come in milk chocolate or almond and dark chocolate) 1 of these = 1 HexB. They're yummy broken up into a yoghurt with fruit or you can have it with your hot chocolate in the evening.
Try swapping your banana for apples, oranges or clementines. Banana's are a natural binder ... and eggs too, so you'll need to up your water intake if you find you eat a good amount of eggs/carbs/banana's to compensate!
I hope this helps and good luck! Also remember, in the grand scheme of things you don't have a great amount to lose, so it may come of slowly. Don't get dishearted if you lost 1/2 lb or STS, it's going in the right direction and you're not gaining
