I think some over eating is a mental health issue and goes beyond changing a diet but most people can unlearn habits if they want to enough and get enough support,. However you can starve yourself to death and so anorexia is a much faster killer. Both can be life limiting though. Anorexia is often about control, over eating is about a lack of control and I would think gaining control is easier than letting go.
