The food you are eating doesn't sound particuarly unhealthy (though maybe try and avoid 'treating' yourself to a take-out on the weekends). You might want to check your portion sizes, I found that I was eating much more than I should.
A bowl of cereal for instance, sounds fine but my bowls of cereal are now about half of my husbands (he fills the bowl to the brim! I used to too ). Try weighing out 30-40g of cereal (check your packet for serving size) and see what that looks like in your bowl. You don't need to weigh things out everyday, but just seeing what a serving size looks like on your own plates can help.
I found that portion sizes were a big chunk of my problem. I lost 6 stone in the year before I got pregnant (I'm still big, need to lose about the same again to be in the healthy BMI range).
I'm also more aware of the energy content of food. I don't count calories everyday or have a set target, but I am aware of how different food choices can drastically affect my intake. And sometimes with snack/treat foods, I look at the calorie content and decide it's really not worth it.
If you had a vegetable portion or two with your main meal then you could have a bit less rice. You would end up with a bit better nutrition and fewer calories, without changing things a lot. It can be something as simple as beans, sweetcorn or peas, if you aren't feeling too adventurous.
Another tip: Use smaller plates - makes small/normal portions seem bigger
I've lost a bit of weight since my booking in appointment, aided and abetted by morning, noon and night sickness. I know it won't keep going down forever, but I hope to maintain at this weight (or slightly lower) for as long as possible before putting on baby weight.
Still kind of annoyed that my booking in appointment was 27th December, so my 'official' weight was on the high side for me leftover turkey
I'm hoping that my risk of gestational diabetes and other weight related issues will be reduced because I'm not eating as much as other people of my weight as I've been losing weight fairly consistantly over the last 14 months. Although weight loss isn't reccomended in pregnancy, I'm just carrying on with the non-drastic lifestyle changes I made before I got pregnant and the midwives seem fine with that.
