:) No, I know; I am not trying to say ZOMG NO FAT! However, left to my own devices I would live on butter, hard cheese, and bloody sirloins, and some form of balance must be imposed. My requirements are simply that less than 35% of the daily calorie intake should be sourced in fat; that the rest should be roughly equally sourced between protein and carbs; and that the day's calories should be <2000, or <1600 if I'm not exercising.

I don't think that's entirely unreasonable. :)
