I don't. I've tried, but it just doesn't work for me

I'm just not what you would call a "tracker".
However, I do use Daily Plate from time to time and this is really usefull for someone like me who can't record something every day on paper or on a spreadsheet. When I'm inexplicably gaining or not losing when I think I should be, I'll track my intake a for a week to try to troubleshoot it, but that's about it.
I kind of admire people who can go back to June 7th, 2003 and tell me everything they ate that day, but I can't even remember much about that month (except it was the midpoint of my weightloss).
I lost weight by replacing refined carbs with veggies and fruits and watching portions. And while I didn't track a thing, I did read every single label, even on veggies.
