I got a Fitbit in January. I log all of the food I eat in the app and it (roughly) calculates how many calories I'm burning through walking or running, plus the passively burnt calories. It's now clear to me why people not measuring tend not to be able to lose weight. They simply underestimate how much they need to exercise, and overestimate how much they can eat. It's an easy trap to fall into. I've had days where eating one thing too many would blow my calorie budget unless I went for a half hour walk to compensate for it.
