“The Body: My Friend and My Enemy” by Dominique-Adèle Cassuto answers the main questions teenagers have about their bodies. How does the body change during puberty? Why do we need a norm and what is a normal weight? Why do we need body positivity and what is body neutrality? How does social media influence our self-perception? The book contains several tests aimed at identifying eating disorders, anxiety due to social media, as well as a self-love diary, handy tips in diagrams, and much more. “The Body: My Friend and My Enemy” is a basic book for understanding yourself and setting boundaries around your body image separately from bloggers on social media.
