GreenWeaver- I would love to become a psychologist or become a counselor specializing in weight related issues.
I really feel for people that are overweight and they often have to deal with their problems with a cognitive therapist before they can begin healing and changing their life for the better.
A therapist can help the patient see what the triggers in their life are that cause the sensation to overeat and counter that with an alternative behavior unrelated to food.
For example, if the patient tends to overeat when stressed, a therapist might suggest that the patient take a walk every time the feeling of panic occurs.
This subtle conditioning allows the patient to seek comfort in walking rather than overeating.
These measures are discussed with one by one until there is no longer a weight issue. Once the patient has effectively lost weight and even reached their goal, the therapy does not end because like any addiction it is managed but never cured.
In order to discourage setbacks a patient will continue to see the therapist but maybe on a less frequent basis. They may join a group like Weight Watchers in order to continue seeking group therapy as well as nutritional advice.
