I track, because I'm anal, & because if I don't things start to sneak in on me.
I actually have an excel Spreadsheet with calorice & macro content of everything I eat. If it's something I make, like spaghetti, I just enter the weights & it comes out with a total for the dish. Then my journal spreadsheet calculates the ratio of the amount I ate (100g, say) to the total weight. Took a long time to set up, but it's fast & easy now.
