The number of calories, cabrs, protein and fat grams right for you is VERY individual, and may not even be in that range. You can try starting with 2000 and see how you feel. Full and not losing fat? Maybe you need to reduce. Hungry a lot and low energy? Maybe it's not enough. Knowing how much you are eating now before you make changes is important too, because too drastic of a change could be detrimental.
