Abstract

In Reply.  —Dr Greenberg raises an important public health issue concerning recommendations for subjects who are moderately obese.

Adoption of public health guidelines advocating weight loss to a BMI of less than 22.5 kg/m2 must be tempered by data that demonstrate that the BMI associated with the lowest total mortality may be higher at 26 to 27 kg/m2 in the elderly than in middle-aged populations.2 We agree that large-scale clinical trials will be required to define the role of weight loss and exercise
