Most of us are unhappy with bits of our bodies. We constantly judge other people on theirs too. Check out why we're so obsessed with body image here...

Body image refers to a person's perception of the aesthetics and sexual attractiveness of their own body. The phrase body image was first coined by the Austrian neurologist and psychoanalyst Paul Schilder in his masterpiece The Image and Appearance of the Human Body (1935). Human society has at all times placed great value on beauty of the human body, but a person's perception of their own body may not correspond to society's standards.

The concept of body image is used in numerous disciplines, including psychology, medicine, psychiatry, psychoanalysis, philosophy and cultural and feminist studies. The term is also often used in the media. Across these disciplines and media there is no consensus definition.

A person's body image is thought to be, in part, a product of their personal experiences, personality, and various social and cultural forces. A person's sense of their own physical appearance, usually in relation to others or in relation to some cultural "ideal," can shape their body image. A person's perception of their appearance can be different from how others actually perceive them.

A 2007 report by the American Psychological Association found that a culture-wide sexualization of girls (and women) was contributing to increased female anxiety associated with body image. Similar findings associated with body image were found by an Australian government Senate Standing Committee report on the sexualization of children in the media. However, other scholars have expressed concern that these claims are not based on solid data.

Studies conclude that women are more worried about their body image than men and that their concern can impact on their health. Commentators note that people who have a low body image will try to alter their body in some way, such as by dieting or undergoing cosmetic surgery.

French child psychoanalyst, Francoise Dolto, has developed a theory of the unconscious body image. Negative perceptions by a person regarding their body, such as a perception that they are fat, can in some cases lead to mental disorders such as depression or eating disorders such as bulimia nervosa, though there can be a variety of different reasons why these disorders can occur.

There has recently been a debate within the media industry focusing on the potentially negative impact size zero models can have on young people's body image. It has been suggested that size zero models be banned from cat walks, with many celebrities being targeted by the media due to their often drastic weight loss and slender frames; for example, Nicole Richie and British Super Model Kate Moss. Some examples of celebrity woman Victoria Beckham, regretted in a similar fashion can be found, but the media seem to focus principally on the effect that the Size Zero phenomenon has on young women. Media however, is generally quick to denounce celebrities endorsing fad diets, including popstars who describe girls who are not under a peer pressurised size, a "social suicide".

Men's body image is a topic of increasing interest in both academic articles and in the popular press. Current research indicates many men wish to become more muscular than they currently perceive themselves to be, often desiring up to 26 pounds of additional muscle mass. According to the study, western men desire muscle mass over that of Asian men by as much as 30 pounds. The desire for additional muscle has been linked to many men's concepts about masculinity. A variety of research has indicated a relationship between men's endorsement of traditionally masculine ideas and characteristics, and his desire for additional muscle.[8] Some research has suggested this relationship between muscle and masculinity may begin early in life, as boys' action figures are often depicted as super-muscular, often beyond the actual limits of human physiology.

Studies have found that females tend to think more about their body shape and endorse thinner figures than men even into old age. When female undergraduates were exposed to depictions of thin women their body satisfaction decreased, but rose when exposed to larger models.

Physical appearance comparison processes appear to play a critical role in the link between fashion media exposure and body image dissatisfaction. And it appears that upwards physical appearance comparisons against idealised images leads to greater dissatisfaction, but downward comparisons, for example against obese people, are associated with better body image satisfaction.
