Weight loss and personality

Does anyone know of any articles discussing weight loss and personality and how they effect each other?

I think I saw this ? posted on the main board last week. I don't know of any specific articles, but I am very interested in what you find out!!! I know what my personal experience has been with this and have read many, many posts from others that have been thru alot like I have due to the drastic weightloss and how that effects our personal relationships.
