I know I was really horrified to find out how many kilojoules/calories are in bread. One of the easiest 'fixes' you can make to your normal diet is to look at how you're using bread and find a replacement.
For example, I'm a huge fan of toasted sandwiches. It was simplicity itself to substitute a low-cal wrap for the two slices of bread - and just that change was enough to halve the calories!
Another easy change is to cook meals that are filling and easy, but low on the 'extras' that add huge calorie bumps to the meal. For example, when you make a quiche, go heavy on the eggs! Believe it or not, they're not that high in calories when compared to the 'satiation factor' you get from eating them. The calories in quiche are mostly in the pastry base and the cheese...so do away with those entirely. It's not necessary at all; quiche cooks perfectly fine without any base. (I've seen recipes that suggest using things like wraps/mountain bread for a base...ugh, no thanks. I'd rather do without entirely, thank you, than have a sub-par substitute.) Also, it genuinely doesn't require cheese - but if you totally need cheese, use low-fat for that; it's one of the few meals that low-fat cheese doesn't actually taste bad in, IMO.
You can make personal mini-quiches in a muffin tray; it's simplicity itself. I break an egg into each (large) muffin slot, then stir in finely-diced capsicum, onion, spinach, mushrooms...whatever happens to be in my fridge. Bake for 25 mins at 180C (I have no idea what this is in fahrenheit) and bam! Almost-instant, individual serving portions with (get this) only about 400kj (100 calories) per serve. And they are super-filling; if you jam enough veggie quotient in there, you'll find that it can be a struggle to get through two. (Best part? They're portable - handy for taking to work - and quite tasty cold, too, if you can't find a microwave. If the kids like them cold, they can take them to work for school lunches.)
Anyway, I know how it is to be eating more or less healthy food and still having a weight problem; for me, the turning point - other than being diagnosed and treated for polycystic ovaries - was realising that it wasn't so much what I ate, as
when I ate it. Don't eat big meals at night, when you're going to sleep - if you find you're hungry late at night, keep diet jello in the fridge ... or even normal jello, though be advised that might cause a sugar spike that'll send you running for sweets.
Anyway, hopefully you'll find some good advice here, or at least some moral support to help you in your quest. Welcome, and good luck!
