Agreed 100%. I think if your strategy for maintaining a good diet relies on weighing food and counting every last calorie, you are inevitably going to fail. Something more fundamental, natural, habit forming, whatever -- that will be the right answer. Naturally trim people don't count calories to stay that way, either.
Of course naturally “trim” people don’t count calories - they don’t have to. Just like I don’t have to monitor my blood glucose level, but my Type 1 diabetic friend does.
You can’t apply to habits of one physiologic group to a different group and expect the same results.
