How to talk to someone about their eating disorder

Be careful to avoid critical or accusatory statements, as this will only make your friend or family member defensive. Instead, focus on the specific behaviors that worry you.

• Focus on feelings and relationships, not on weight and food. Share your memories of specific times when you felt concerned about the person’s eating behavior. Explain that you think these things may indicate that there could be a problem that needs professional help.
• Tell them you are concerned about their health, but respect their privacy. Eating disorders are often a cry for help, and the individual will appreciate knowing that you are concerned.
• Do not comment on how they look. The person is already too aware of their body. Even if you are trying to compliment them, comments about weight or appearance only reinforce their obsession with body image and weight.
• Make sure you do not convey any fat prejudice, or reinforce their desire to be thin. If they say they feel fat or want to lose weight, don't say "You're not fat." Instead, suggest they explore their fears about being fat, and what they think they can achieve by being thin.
• Avoid power struggles about eating. Do not demand that they change. Do not criticize their eating habits. People with eating disorders are trying to be in control. They don't feel in control of their life. Trying to trick or force them to eat can make things worse. 
• Avoid placing shame, blame, or guilt on the person regarding their actions or attitudes. Do not use accusatory “you” statements like, “You just need to eat.” Or, “You are acting irresponsibly.” Instead, use “I” statements. For example: “I’m concerned about you because you refuse to eat breakfast or lunch.” Or, “It makes me afraid to hear you vomiting.”
• Avoid giving simple solutions. For example, "If you'd just stop, then everything would be fine!" Adapted from: National Eating Disorder Information Center and National Eating Disorders Association - http://www.helpguide.org
