You can't take charge. Mealtimes should not become a battleground. Emotions, such as anger and frustration, need to be expressed, but not at mealtimes. Try to take the focus off food . Discussions of food intake or weight may encourage the sufferer to use the disorder as a tool to manipulate others.
Communication is most important.
However, be aware that the sufferer may try to talk about food constantly. You may need to change the subject. Take care to be sensitive when commenting on the person's appearance , and try to encourage the sufferer to develop positive activities and interests that do not revolve around food. The person with the eating disorder should not receive attention due other members of the family or other friends. That person is important, but no more so than anyone else.
