Do I have an eating disorder or am I just goal oriented?

Was watching Dr. Oz yesterday, and he had on a woman with anorexia. Needless to say, the woman looked terrible and there was no question that she was in trouble and could die. But I am confused. There have been studies where reduced calorie intake has led to longevity. I think it was reducing the calorie intake recommended by one third.

Two of the signs of an eating disorder concerned me as I watched the show. One was a preoccupation with food.
Well, I admit, I am preoccupied with nutrition. I don't rule out food groups but do keep track of what I eat. I would say that I eat mindfully rather than mindlessly. How else can you even maintain never mind reach your goals?

The other sign that concerned me was a preoccupatiion with exercise. How much is that? She said that exercising when you are sick is bad. Well, since I exercise regularly and a lot, I am rarely sick. Another was missing work to exercise. Well I don't work but I would rather do a workout dvd than vacuum. I guess I do take off of work. Is the hour to hour and a half that I do every day too much? I don't feel like arguing about it, but I feel great doing it and it has become a kind of addiction but I don't think that I am on the road to anorexia.

I am on the side of the study that showed that being on the skinny side and eating less calories than you need is healthy. I saw the obese rats as opposed to the thin ones. The thin ones of the same age as the obese, looked young and health whereas the obese ones looked old and sick. I think that I am a long way from becoming anorexic.
