I think the experience that the OP is talking about is fairly unique. It has always been my experience that people who over eat and are obese are objects of scorn and ridicule, whereas those who under eat to the point where their health is affected are viewed more along the lines of being mentally ill.
As an aside though, working in the healthcare field has shown me what the long term effects of obesity are first hand. Looking at the shape some of these people are in (amputations from diabetes, unable to bear their own weight for more than a few seconds, soiling and being unable to properly wash themselves), I would rather be put down like a dog than end up in that situation. This movement towards acceptance of the grossly overweight is dangerous, as is calling it a disease. Most of the people in this situation are already full of excuses for why they are the way they are, that adding any more only compounds the problem. There are a few rare genetic conditions tat predispose someone to put on weight, but most of these are glandular, and can be controlled with medication.
I put on 40 lbs when my wife was pregnant. I felt like crap all the time. After maybe a year or so I decided to do something about it. I fixed my diet (fresh veggies, meat, limited carbohydrates, whole grains, no processed sugar or junk), and got back into an exercise routine. I am currently running 30-40km per week and weigh in at 180-185lbs (at 6'1"). I feel better, I look better, and was able to do this while working and with a very young child at home (my wife also works). There is no reason that most people could not accomplish the same thing if properly motivated. It was a real lifestyle change, not a diet. You also really need to look closely at the nutritional information on food since a lot of stuff that is marketed as healthy is really full of garbage.
