Low total energy expenditure (TEE) has been hypothesized as a weight gain risk factor, but TEE's repeatability is understudied. This study analyzed repeated doubly labeled water (DLW) measurements of TEE in adults and children from the IAEA DLW Database. High repeatability of TEE was found in adults, but not children. No correlation was found between body composition and TEE in adults. Increases in adjusted TEE were associated with weight gain but not changes in body composition. This suggests low TEE isn't a weight gain risk factor, and high TEE doesn't protect against it over the timeframes tested.
