Body image is a person's thoughts, feelings and perception of the aesthetics or sexual attractiveness of their own body. The concept of body image is used in a number of disciplines, including psychology, medicine, psychiatry, psychoanalysis, philosophy, cultural and feminist studies; the media also often uses the term. Across these disciplines, there is no single consensus definition, but broadly speaking body image consists of the ways people view themselves; their memories, experiences, assumptions, and comparisons about their own appearances; and their overall attitudes towards their own respective heights, shapes, and weights—all of which are shaped by prevalent social and cultural ideals.
