According to research, people with feeding and eating disorders:

A) are not bothered by others' opinions.
B) are flexible in their self-evaluations.
C) have a dichotomous thinking style.
D) rarely conform to others' wishes.

People with feeding and eating disorders tend to have a dichotomous thinking style, meaning they see things in black and white, with little room for grey areas or flexibility in their beliefs and attitudes towards food and their bodies. This rigidity in their thinking can perpetuate the disorder and make it difficult to break free from disordered eating behaviors.
