Kara Becker, a certified eating disorder therapist and national director of eating disorder programs at Newport Healthcare, explained to HuffPost, “Bigorexia is a psychological condition and type of body dysmorphic disorder which involves a distorted self-image that focuses specifically on muscle size and physical appearance.” Also known as muscle dysmorphia, people with bigorexia see themselves as small or underdeveloped, even when they already have large, toned muscles. Studies confirm that muscle dysmorphia is more common in boys, men, college students, and male weightlifters, according to the National Eating Disorders Association.
