None of the long term fit people I know count calories. They tend to do a couple things:
1. Have well functioning hunger, which comes from 2. Eating whole foods and 3. Eating high satiety foods
I'm pretty steadily at my lean weight. But when I'm not, I just switch to higher satiety foods and the weight comes off.
This method is both easy and simple, but I rarely see it recommended. Are there people it doesn't work for?
(Of course, the hard part of this method is having a personal dietary culture that includes buying, cooking and eating whole foods.
Note that I'm not including cost, because in areas that aren't good deserts whole foods tend to cost less than processed foods)
