There are plenty of factors to take into consideration.
It depends on your personal average of metabolic status.
Likewise (if I am not repeating myself) it also depends on your body type, whether or not you are an Ectomorph, Mesomorph or Endomorph or somewhere in between.
You would need to calculate your current weight based on what the average weight should be for your body type
and then consult your doctor as well as a nutritionist to see what your daily caloric intake etc. should be.
It's by no means an easy thing to break down your own nutritional needs on a regular basis.
It's tons of math and tons of trying out various ways to see "what works" and "what doesn't".
My personal "way" I go by (which may or may not work for you) that seems to work for me is to consume the most needed daily amounts that my Iron Age ancestors were consuming (and perhaps a bit more here and there of the healthier things because of more modern necessities).
So long as you keep exercising on a daily basis, consuming enough amounts of carbohydrates, proteins, vitamins and minerals (etc.) at the correct times of day and allowing enough time for your body to get enough sleep at night, you should be in a decent nutritional regiment for what you need in no time.
There is an earlier thread where a bunch of us were discussing certain diet procedures that we felt were helpful for us.
I will try to dig it out and find it for you, if you are interested.

In case you are interested, here is the thread: http://www.therlsh.net/t9497-pai-mei-diet Hopefully some of the info there will be useful for you (despite the tedious discussion between Flora and myself...hehe!).
--Speaking of which, Flora is also an amazingly well-versed professional Nutritionist. It might be helpful to chat with her further with regards to your queries. \m/
