Abstract
Diagnosis of clinical obesity has been highlighted by the recent publication from a Commission Report in The Lancet, suggesting the addition of a new diagnostic category, "Preclinical Obesity," to the already existing ones. Diagnostic criteria for obesity began in the first half of the 20th century, when life insurance companies provided information tables of ideal body weight levels and/or desirable body weight levels based on actuarial associations with mortality. This was replaced by the body mass index or BMI in the third quarter of the 20th century. This tool documented the epidemic of obesity in the US in the last three decades of the 20th century. The recognition of the importance of fat distribution, pioneered by the work of Jean Vague in France, provided a new understanding of obesity. The limitations of BMI and the availability of effective new treatments have heightened the need for new diagnostic guidelines. Obesity represents an increase in body fat and an alteration in its distribution and function. But at the same time, obesity is a stigmatized word and a pejorative term. This communication discusses ways to better diagnose the increase in body fat and its abnormal distribution. We ask whether there is an alternative word to replace obesity and suggest that adiposity or healthy weight could be options.
