Ah, I can possibly actually help a smidgen there.

Don't count calories. Instead, work on getting nutritionally dense foods into you.

I lost several dress sizes. I never counted calories. I just tried to eat healthier.

I think we keep eating as long as we need some nutrient or other. We stop when our nutritional needs are met. This is why eating "empty calories" really packs the pounds on.

Also, try to get some walking in, even if you "don't really exercise." (I mean sports, gym, etc.) Take the stairs, not the elevator. Park a little farther out instead of circling like a vulture looking for the closest spot. Etc.
