A lot of people who post things here simply do not understand the dynamics of addiction. As someone who has lost over 100 pounds at least 3 times in my life, it is not as simple as "knowing what to eat and moving more." I've read it all, tried it all - except surgery, and it is a lifelong chronic problem for many people with no "cure." It is more than willpower can fix. It is more than surgery can fix; a lot people undergoing these surgeries have long-term health problems because of it. There is more to morbid obesity than even the medical/psychological community understands. Too much money is being made off of fat people for the medical industry or the science industry to find decent solutions.
A fairly new good read out right now is Sylvia Tara's "Secret Life of Fat." It chronicles the science behind why so many gain their lost weight back.
Unfortunately, people who are obese are judged by others who are "driven crazy" because of their behavior. Instead of judgment, how about sincere compassion and hopes that someday there will be a solution.
