It depends on how much you weigh, and how many calories are in your body in the first place.
Approx. 15 calories per pound body weight, per day, will sustain a persons weight.
It entirely depends on your body weight, body mass, diet plan and stamina. Please specify to get an accurate answer.
How much you need to eat (i.e. how many calories you need) is depended on height, weight, age and how much "stuff" you do in a day. However 'weight' (i.e. bodyfat) depends on how much you actually eat, relative to what you need to eat. So body fat is slightly dependent on height and weight, but not directly.
I've heard that .9g per pound of body weight per day is sufficient. I've also heard of heavy weightlifters doing up to 1.5g per pound of body weight per day.
