I mean this in the kindest possible way, as someone who has struggled like you for many years, but I fear you are setting yourself up for a fall by not eating enough. You will, most likely, trigger a binge by denying yourself so much.
I would suggest you graze a bit more; just have a few nuts or some fruit or even a bar of chocolate if you want it. Let's face it, you and I did not get to be overweight by eating normal calories. I know for a fact that I averaged a good 3500 cals per day, maybe more. That means that by reducing that to even 2500 I will lose weight. You CAN eat more than you are doing and still lose weight. As long as you are eating less than you used to, you will lose weight. Gradually, as your body gets used to lower calories and your stomach shrinks then you will find your calories dropping naturally.
Again, please know I am saying this to you from the heart and not in a 'wagging finger' kind of way because I really, really know how bloody hard this is! I am doing this myself and it might shock some to know that I eat chocolate every day and am having chips for tea tonight. I'm still losing weight because I used to eat those things AND a fat load of other stuff on top.
