How to lose weight?

Used to eat more, eat breakfast now is basically bread, noon to eat some staple food, but eat much less than before, and at night sometimes eat the staple food, but a little more food to eat, go for a run after dinner 2 laps (one lap around 1KM). Why weight cut only a 0.5-1KG, the next day the same plan on the third day is the same, but eat more to go up two days later went back to the beginning of the weight, it should be how to correctly lose weight, do not want to remain so.
