Abstract Changes in energy regulation occur during normal aging and contribute to the
common phenomenon of weight and fat losses late in life. This review synthesizes data on …

This paper describes the Observing Protein and Energy Nutrition (OPEN) Study, conducted
from September 1999 to March 2000. The purpose of the study was to assess dietary …

ContextExercise is associated with mortality benefits but simply expending energy through
any activity in an individual's free-living environment may confer survival advantages …

The accuracy and noninvasive nature of the doubly labeled water (DLW) method makes it
ideal for the study of human energy metabolism in free-living conditions. However, the DLW …

Underreporting of energy consumption by self-report is well-recognized, but previous
studies using recovery biomarkers have not been sufficiently large to establish whether …

Background Studies suggest that physically active people have reduced risk of incident
cognitive impairment in late life. However, these studies are limited by reliance on self …

Background. Objective methods to measure daily energy expenditure in studies of aging are
needed. We sought to determine the accuracy of total energy expenditure (TEE) and activity …

Despite recent interest in water intake, few data are available on water metabolism in adults.
To determine the average and range of usual water intake, urine output, and total body …

This study evaluated the validity of the total energy expenditure (TEE) estimated using
uniaxial (ACCuni) and triaxial (ACCtri) accelerometers in the elderly. Thirty-two healthy …

Combining accelerometry (ACC) with heart rate (HR) monitoring is thought to improve
activity energy expenditure (AEE) estimations compared with ACC alone to evaluate the …
