Lynn is right.
what I do, is figure protein first, since we know that needs to be 1g per pound of lean body mass.
then I do fat, because that should be .4-.5g per pound of lean mass.
then the rest comes from healthy carb choices, mostly around my workout time, and tons of veggies all day except immediately post workout.
carbs should fluctuate depending whether you are bulking or cutting. protein is always a constant, and fat usually doesn't waiver much either.
