Comparison of self-reported, measured, metabolizable energy intake with total energy expenditure in overweight teens.

ABSTRACT:

Background

The accuracy of dietary energy assessment tools is critical to understanding the role of diet in the increasing rate of obesity.

Objectives

The purposes of our study in overweight adolescent boys and girls were 1) to assess the energy reporting bias of diet records against the referent of total energy expenditure (TEE) and 2) to compare the methods of determining energy needs by using measured metabolizable energy intake (MEI) and TEE.

Design

Twenty girls [12-15 y, body mass index (in kg/m2) = 33.0 +/- 5] and 14 boys (12-14 y, body mass index = 27.4 +/- 4) participated in 2- to 3-wk metabolic balance studies. TEE was measured by using doubly labeled water (TEE(DLW)), and MEI was measured by bomb calorimetry of composite daily diet, urine, and fecal collecti
