What is the main theme and feministic approaches?
The central theme of The Edible Woman is the consumption of the self and the lost of one's independence by the expectations of society.
Marian is a progressive and independent woman who has found herself stuck in a rut: She is engaged to be married and feels that this will be the end of life as she knows it. Rather than embracing the engagement, she realizes that marriage is nothing but a burden placed on women by a society which second guesses them. Hence she develops an eating disorder, a form of anorexia, in response to her fear of being "eaten" or consumed by this new life. This is why the central topic is related to this fear of being taken over, and to lose one's own identity.
