This is certainly an interesting discussion. I have been trying to lose weight the old-fashioned way and I am satisfied with my progress so far. I belong to a weight loss mailing list and many of the surgeons have had horrible experiences with physicians.
Several people (most of the members are female) are in the 300-400 lb range and I don't think you have any idea of the desperation that they feel. Many of them are housebound and have many of the obesity related diseases. They are used to people pointing at them in the street and yelling at them from their cars. They worry about fitting into airplane seats and carry seat-belt extenders with them when they travel.
Most people on the list know by now that I am a surgeon and I do my best to answer questions if they are directed at me. I will correct misinformation but I try to avoid defending our profession. Nevertheless, just today one member accused me of being "just like other doctors...arrogant and judgmental". I was assured by other members that I was not in error but, unlike this list, dissent is not valued. Like most people with a chronic disease, they are more informed than I am about new drugs and strange new weight loss methods. They have tried every diet imaginable. I think there is considerable prejudice in the medical profession towards the obese. I would never have bariatric surgery but, if I had some of the experiences that I've heard about, maybe I would have a different opinion.
