Whilst I do agree that some people's comments make me think they have slightly disordered eating, I don't think it's automatic that anyone who consciously monitors what they eat and exercise has an eating disorder. I think that if your monitoring what you eat and exercise has an adverse impact on your life, it is a problem - e.g. if you turn down a social event because of food, exercise to the point where you're trying to run despite being ill/injured, or get upset if you have to eat a cookie lovingly made by your 8 year old DC (examples only).
In specific response to @Jemenfouscompletement - I'm sorry you feel that way. I think what this thread and a similar thread (on habits of naturally slim people) show is that for many people, maintaining a healthy weight is very hard for some people.
There is a reason why white carbs (rice, bread, corn and pasta) are the most common food worldwide - a cheap way to feed the masses for manual labour.
Fresh veg and fresh protein cost more (time and money) than pasta, bread and white rice. It is also much harder to fit in the physical activity now than it was 100 years ago or even 30 years ago - we work longer hours than anyone in Europe, at sedentary jobs, and many women then have to come home to do the second shift, so for some, getting in 20k steps a day requires significant sacrifice (i.e. giving up time spent with DC or DPs, or getting less sleep, not just sitting in front of the TV less).
So combine cheap white carbs and not enough exercise, and you get increasing insulin resistance for many. Not to mention aggressive marketing and complicated relationships with food (where many people associate food with love, or have been brought up to feel guilt for not clearing their plate "because there are starving children in Africa).
So it really does show ignorance if you say that there is no excuse for being overweight. There are some really complicated "excuses" and we'd do much better at helping everyone address these than dismissing them as lazy or whatever because they haven't been able to address them.
(Having said that, I think we really really do need to help people and encourage them to at least put some effort into getting to a healthy BMI, in the same way that we need to help people quit smoking).
