This video shows exactly how the environment can affect people with eating disorders. These sisters are constantly competing with one another to make sure they are not considered the “Fat twin”. They know they are too skinny, but their brain is telling them they can not gain weight. Their brain is now trained to believe that food is bad, and not eating is good. They do not feel sick anymore because their body has gotten used to being deprived, and when they do eat they get sick. This video shows how these disorders are not just physical but mental as well, and these disorders do affect the brain in a negative way.
