Im not entirely sure that carbs from bread and sugar are necessarily bad- white bread carbs are prob not the best, but whole grain bread is pretty good for you, and remember that fruit contains sugar too
Protein helps keep you full too, which is really handy in weight loss

Im not sure exactly how much you want, but you might want to try and have some protein in every meal, and if you find yourself getting hungry try to have a snack that has some protein in it too to keep you going
