Comfyshoes- I agree with you because a person has to want to change.
I was recently watching a documentary on the inpatient rehabilitation hospital Brookhaven in New York.
It is a rehabilitation hospital that treats morbidly obese patients. Many of these patients are no longer mobile and this hospital is their last chance at recapturing their lives.
They receive group counseling along with individual and family counseling and weekly status meetings regarding any challenges the patient may have had.
They also receive physical and occupational therapy with the goal of getting the patients to the point that they are able to exercise daily which is when they really start to lose weight.
Like the drug addicts these people are addicted to food and some may not even be ready to change their ways even when they reach the hospital.
There was a case of a man that snuck in junk food and was not following the diet even though the doctors told him that if he does not change he might not live to see his next birthday.
For most people the fear of death is motivating enough, but it is not for all people.
I imagine that there must be a certain level of depression and hopelessness that goes along with this type of addiction because once your mobility goes the quality of your life starts to deteriorate quickly.
