Since people with eating disorders tend to be secretive about their illness, friends and family should watch for the warning signs:
•preoccupation with weight and calories, regardless of body size
•strict avoidance of "fattening" foods
•excessive exercising
•irritability, depression
•social withdrawal
Here's how to support someone with an eating disorder:
•Let the person know you want to help
•Focus on the person's overall wellbeing, not their food intake eating or weight
•Be a friend, not a food cop
•Be patient and compassionate
•Learn about eating disorders and services in your area
