I think that is really true. When it's not your job to do it, it's really hard to maintain the number on the scale as a top priority. I mean, we all have lives to lead. Even people whose job it is fail at it. At my Y, every single instructor is fairly overweight or significantly large. I don't really care about how large my fitness instructor or trainer is as long as they know what they are doing, but a lot of people would consider trimness essential to that role. But they are almost all obese, not just a little pudgy. Fundamentally, it doesn't affect their ability to do pushups or hold that yoga pose, so it becomes secondary. But every day practically there is cake on the counter at the reception desk or some other carby evil. The food culture at that place is deadly.
