Coming from someone who has experienced eating disorders… 
 -be extremely supportive and patient 
 -Avoid commenting on appearance or weight. People with eating disorders are already overly focused on their bodies. Even assurances that they’re not fat play into their preoccupation with being thin. Instead, steer the conversation to their feelings. Why are they afraid of being fat? What do they think they’ll achieve by being thin?
 -Avoid giving simple solutions. For example, “All you have to do is accept yourself.” Eating disorders are complex problems. If it were that easy, your loved one wouldn’t be suffering.
