I tracked my calories on livestrong for two weeks some time ago, just because I was curious.
Now I know that when I eat "just by feel" - when I'm hungry - I pretty much exactly meet my "calorie goal" (which makes sense doesn't it ).

I do watch what I eat and don't eat empty calories or crap and do eat lot of vegetables - I guess that's part of the secret why this works for me, it's simply hard to overeat on meals that contain mostly vegetables.

I don't plan on tracking my calories again.
