Prevention: There is insufficient evidence to recommend in favour of or against community-based obesity prevention programs; however, because of considerable health risks associated with obesity and the limited long-term effectiveness of weight-reduction methods, the prevention of obesity should be a high priority for health care providers.
(grade C recommendation)
Treatment: For obese adults without obesity-related diseases, there is insufficient evidence supporting the longterm effectiveness of weight reduction methods.
(grade C recommendation)
Treatment: For obese adults with obesity-related disease (e.g., diabetes mellitus, hypertension), weight reduction is recommended because it can alleviate symptoms and reduce drug therapy requirements, at least in the short term.
(grade B recommendation)

(grade C recommendation)
Detection: For people with obesity-related diseases, BMI measurement is recommended because weight reduction should be considered with a BMI of more than 27.
