I can add to that, attesting to the differences! I experimented with different ways and feel best on 55% carbs, 25-30% protein, and 15-20% fat. I feel best with that and it's also been successful to getting me to my goal. Your body is so individualized that it will take some trial and error. The FitDay logs will help keep track of the proportions on any given day; you might want to jot down how you feel physically and try to match it up to see if there are any patterns.
And now that you don't have to be perfect, you can be good.
