I assume that the majority of fat people are willing to trade their health, looks and acceptance in "normal" society for plenty of really tasty food. They, the doctors, should treat obese patients like common drug addicts because that's all they are. It's a lifestyle that is chosen and they love and hate it similar to how a heroin junkie feels about chasing the dragon.
This is exactly it, people have food addictions that are just as compelling as drug addictions, even the most addictive ones. It takes an enormous amount of willpower for a fatty to diet properly long term, much much more so than someone who has never been fat. I've done a lot of work with these kind of people, and it takes
years of dedication to fully reintegrate.
I have seen a friend/advisee in what I can only describe as "food withdrawal". This person was over 280lbs of fat, down from 350 or so, and they called and said they needed help. We were roommates at the time, and when I got home they were lying down on their bed in the fetal position, with a grimace on their face that make them look they they had just been shot. Over the next hour, I saw them go from tears to rage and back again, muscles clenching like they were in agony. All of this was from food cravings, but they had enough willpower to resist that time.
This was not a weak person in general, I had seem them quit smoking cold turkey from a pack a day like it was nothing. When the food cravings had subsided, I asked him what he had felt and he looked me in the eye and told me something I will keep with me for a while: "It was like the only thing in life I wanted was food, and the only way I could stop from doing something about it was to keep screaming in my head."
This is some seriously fucked up shit these people have to go through. Say what you will about initial causes, but a 400lber that gets below 200lbs through diet and exercise alone and stays there for 5 years has as much willpower and self-control as most bodybuilders ever will.
