Eating Disorders and who support them

In the article that I read it talked about what type of supporters people with eating disorders have. The article described six different types of people who support there loved ones or friends with eating disorders. 

The type that everyone should be is called "The Dolphin", which is the ideal caregiver and shows the person with the eating disorder the right behaviors they should be displaying. The other types of supporters can be too controlling like "The Terrier" or even too anxious and angry at the person with the disorder like "The Jellyfish". "The Ostrich", "The Rhino" and "The Kangaroo" are the other types of supporters a person could have.
Question: Do you think that the type of caregiver can help or harm the patient? If so why?

What's the Link Between Eating Disorders and Vegetarianism?

In the article: "What's the Link Between Eating Disorders and Vegetarianism?" the author describes the possible links between eating disorders and vegetarianism during, before, or after an eating disorder. 

The author explains the average age of eating disorders starting at age sixteen, and the average age of vegetarianism starting at age seventeen. The author furthermore explains reasons why someone with an eating disorder might become a vegetarian. Some examples are the excuse of rapid weight loss and becoming a "vegetable junkie". She then mentioned how vegetarianism can help overcome eating disorders.

Do you think there is a possibility of eating disorders and vegetarianism being linked together?
