What it actually means
Eating disorders are serious medical conditions, not lifestyle choices.
Eating disorders are serious mental health conditions defined by disturbances in eating behavior and a disrupted relationship with food, weight, or body. The major categories include anorexia nervosa (significant restriction of food intake, intense fear of weight gain, disturbance in self-perception), bulimia nervosa (recurrent binge eating followed by compensatory behaviors), binge eating disorder (recurrent episodes of binge eating without regular compensatory behaviors), and OSFED, clinically significant eating disturbances that don't meet full criteria but are no less serious.
Eating disorders are not a phase, a diet, or a lifestyle choice. They are medical conditions with real mortality risk, especially when untreated and especially when paired with substance use.
