The food that you eat, regardless of your gender, should be enough to support your daily activity level. If you train hard, then you must eat more than if you don't. If you chase after three kids all day long, then you must eat more than if you had no children and watched TV all day. Again, this doesn't matter whether you're a man or a woman.
Exactly what is appropriate for you is a matter of experimentation over time. The more attention you give to exactly how your body reacts
to food intake (and exercise/activity), the sooner you'll be able to zero in on what your specific body needs.
