Eating disorders are a group of mental illnesses that affect the way you feel about food and the way you feel about your body and yourself. There are three main eating disorders: anorexia nervosa, bulimia nervosa and binge-eating disorder. While these are all called eating disorders, it’s important to remember that these disorders are about much more than food—they’re also about how you feel about yourself, how you cope with your feelings and other deeper factors.
Millions of people aren't happy with the way they look. In fact, the National Eating Disorder Information Centre estimates that up to 40% of nine year-old girls have dieted to lose weight—even when they were at a normal weight.
Body image and self-esteem start in the mind, not in the mirror. They can change the way you understand your value and worth. Healthy body image and self-esteem are a big part of well-being.
Body image is both the mental picture that you have of your body, and how you perceive yourself when you look in a mirror. Self-esteem is how you value and respect yourself as a person—it is the "real" opinion that you have of yourself.
