Validity of self-reported energy intake in lean and obese younger women, using two nutrient databases, compared with total energy expenditure assessed by doubly labeled water

Abstract

To compare self-reported total energy intake (TEI) estimated using two databases with total energy expenditure (TEE) measured by doubly labeled water in physically active lean and sedentary obese young women, and to compare reporting accuracy between the two subject groups. Both physically active lean and sedentary obese women under-reported TEI regardless of database, although the magnitude of under-reporting may be influenced by the database for the lean women.
