Many individuals suffering from a anorexia ‘hide’ behind specific diets to deal with social situations (e.g. vegan lifestyle, raw diet, ...)
Muscular Dysmorphia (bigorexia):
-
This type of eating disorder is commonly experienced by men and by very athletic people.
-
A person suffering from muscular dysmorphia may follow very strict dietary guidelines, work out a lot or too much, and take supplements.
-
These people feel shame and guilt when they are unable to follow their intense training and dietary regimens.
