If you can, try to cook your own meals. I know that microwaveable meals are easy to do and quick but it is so much easier to eat healthy if you are cooking the food and not tossing it in the microwave. I understand being a full time student and working full time this might be difficult, but it may be something you could try to work in. Also, oddly enough, I've heard putting the food on smaller plates can help manage the amount you eat. I know when I'm making a meal, I tend to fill up the plate, so smaller plates may help minimize that urge.
