Avoid extreme restriction, fasting, or purging to control weight
In a meta-analysis, people with anorexia nervosa had roughly 5.9 times the expected mortality for their age, with 5.1 deaths per 1,000 person-years; about one in five deaths was suicide. A three-year study across 44 schools found that girls who severely restricted food had 18 times the risk of developing an eating disorder compared with those who did not diet. The source favors physical activity over severe dietary restriction for adolescent weight control. This is not a recommendation to replace restriction with compulsive exercise.
