Getting on well with this healthy eating malarkey - but what could I do better?

So just over a month ago, I realised my diet and lifestyle needed a massive kick up the arse. I have always been fairly healthy, but since the start of the year I had basically been lurching from one carb binge to another ("Sandwich for lunch? Don't mind if I do. Giant bowl of pasta for dinner? Certainly!"), eating out a lot, having two or three takeaways a week, going to the pub a couple of times a week and barely eating any vegetables. Unsurprisingly I put on weight, felt tired all the time, sluggish, cranky, and just not like myself.

Over the past few weeks, I've cut out bread, pasta, alcohol and takeaways, and feel about a million times better. One of the big problems was that when I got hungry, I would eat anything I could lay my hands on, so instead I've been planning my meals and haven't been getting hungry. I've also started going to classes at my gym, which suit me way better than just going to the gym and doing my usual routine.

My goal is to lose weight and so far, I've lost an average of 1.6 pounds per week. I'm just over 12 stone and I've set targets for myself, but have kept them small and manageable (there's no time target on them but they're all about losing 7lbs in increments, or getting down to a certain weight).

So given all that (thanks if you're still reading!), does anyone have any tips or advice on things I could be doing better in my diet? I'd like to be losing a bit more per week, but realistically I know that 1.6lbs per week is solid and is sustainable. I guess reading the forum and seeing people talking about losing a stone in a month has made me feel like a bit of an underachiever!

Here's a couple of typical days:

Breakfast: Porridge with banana and a bit of honey
Lunch: Ryvita x 3 with peanut butter and banana
Dinner: Chicken fillet, spinach with feta, cauliflower and carrots
Snacks: Grapes x 10, almonds x 5, apple, satsuma (hmm, that's a lot when I put it all down!).

Breakfast: Porridge with banana and a bit of honey
Lunch: 3-egg omelette with mushrooms
Dinner: Roast turkey with spinach, broccoli, carrots.
Snacks: Satsuma x 3.

Also, I generally do two cardio classes (spinning and swimming) per week and one strength (TRX). I also cycle into work but it's only 10 minutes so don't think that really counts (damnit).
