In April 2008, the French congress passed a law prohibiting so-called \'thinness promoting messages\' in websites, magazines, luxuary boutiques, and advertisements. Also in many countries in Europe and the U.S., the fashion industries set a rule restricting the weight of a female model to not less than 55kg when her height is 175cm. These actions seemed triggered by, and cast out as a remedy for, a series of deaths caused by the use of excessive weight loss medicine as well as the heartless anorexia. The present study is focused mainly on the effects of TV/DVD viewing on the viewers\' desire for losing their weights. Also examined include the relations of the two variables, or television viewing and desire for weight loss, with their demographic characteristics, actual body mass indices, leisure activities, and leisure satisfaction. The results of path analyses indicate that highly educated, young females tend to have higher desire for weight loss, regardless of their actual body mass indices, and this tendency is intensified for those who are categorized as heavy TV/DVD viewers. Other findings include the facts that people who are high in body mass index tend low in leisure satisfaction; women think desirable a body shape that is slimmer that the one men believe ideal; people who live in big cities or with financial affluence are generally high in desire for weight loss; and people who have high body mass indices tend not to enjoy meeting with others. These results signify that, although those who are excessively obese are better to have desire for reducing their weights to improve their interpersonal relationship and leisure satisfaction, the fact that those who watch TV/DVD more were found to show greater levels of the desire regardless of their actual body mass indices should be considered a signal suggesting a need for thorough investigations of the media\'s contents to examine if they include the messages that explicitly promote thinness or implicitly treat ideal the body shapes slimmer than normal.
