Research has revealed that about 40% of adult men and 55% of adult women are dissatisfied with their current body weight. Similar findings have also been reported at high school level, mainly with female students. At the college level, a study found that 85% of both male and female first-year students desired to change their body weight. The primary cause of this concern is the value that American society in general assigns to physical appearance. Thinness is currently an attribute that females desire highly. Males generally desire muscularity. The vast majority of individuals who want to change their body weight do it for the sake of appearance. Most want to lose excess body fat, while a smaller percentage of individuals actually want to gain weight.
