2300 seems really low for the food you've put on that list, things like peanuts and bagels have got shit loads of calories ? I reckon its probably more like 3000+ for your food, and whatever you're drinking throughout the day is gonna be extra. Also I'll assume you like a beer now and then and they're around 200 calories a pint.....
I've managed to shed just over 3 stone since February pretty much by just cutting down on the shit i used to eat, and when i eat it. I work nights so i have a big dinner before work and then burn it off through the night and go to bed hungry. Also I've been using the "myfitnesspal" app the last few weeks to keep a diary of what I've been eating and to help get rid of the last stone i want to lose, counting calories to lose weight does suck both cock and balls but it does work as long as you include EVERYTHING that you're eating and drinking.
