I'm not a fan of tracking food for the rest of your life, but if you truly think you are eating all of the right things (ditch the Starbucks and any canned shakes), then tracking can be a useful tool.
I like LiveStrong (good database, super simple smartphone app), but everyone has their favorite. As you enter foods into your food log, make sure that the data is correct because a lot of data is entered by other member that may not have a clue what they're doing.
If I'm doing things right (for me), the majority of my calories (60%) will come from fat, then a bunch (25%?) from protein and the remainder (15%?) from carbs. Your mileage may vary.
