Eating disorders are among the most dangerous—and misunderstood—adolescent mental health problems. This trusted, groundbreaking resource has helped many tens of thousands of parents play an active role in recovery when their teenager's dieting, working out, or body image concerns cross the line. Treatment experts James Lock and Daniel Le Grange separate fact from myth about anorexia nervosa, bulimia nervosa, binge-eating disorder, and avoidant/restrictive food intake disorder (ARFID). Vivid stories show that when families work together to get the most out of treatment and prevent relapse, eating disorders can be beat. Parents learn specific, doable steps for finding the right care, monitoring their teen's eating and exercise habits, managing family meals, ending weight-related power struggles, and teaming successfully with professionals. The revised third edition incorporates key research advances, updated treatment recommendations, new vignettes, and expanded coverage of ARFID.
