Bigorexia, or muscular dysmorphia, is characterised by the feeling of being too skinny or never muscular enough. It is also called megarexia or reverse anorexia. Bigorexia is an eating disorder more commonly experienced by men and by very athletic people. A person suffering from bigorexia might follow strict dietary guidelines, work out a lot or too much, and take supplements. Feelings of shame and guilt are present when the person concerned is unable to follow their intense training and dietary regimens. Other activities, hobbies, and moments of relaxation are put aside in favour of working out.
