This article reviews recent research on the prevalence and virulence o
f obesity as a causal risk factor for mortality and morbidity. The pre
vailing assumption that obesity, by itself, is a chronic disease or a
primary risk factor for health is challenged. A historical perspective
is used to analyze the efficacy of various medical and educational ap
proaches that have attempted to alter body size in the pursuit of enha
nced physical health. The motivational discrepancies between society's
media-induced desire for thinness and the health field's risk reducti
on approach to weight loss are outlined. Finally, ethical issues are r
aised in relation to current weight control measures, implications for
future educational efforts are discussed, and potential guidelines fo
r future weight management programs are presented.
