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 several disciplines, including neuroscience, 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 appearances; and their overall attitudes towards their respective heights, shapes, and weights—all of which are shaped by prevalent social and cultural ideals.
