Adherence
The Stanford Seven-Day Physical Activity Recall (7D-PAR) provides a reasonable estimate of mean total daily energy expenditure (TDEE) and physical activity energy expenditure (PAEE) for group-level epidemiological studies, but exhibits high individual variability that limits its validity for assessing individual energy expenditure.
If you are using a 7-day physical activity recall or similar self-report tool to track your own daily calorie burn for weight loss, do not rely on the specific number. The tool is designed for group averages in research, not individual precision. The error margin is so large that the specific value is likely misleading for your personal diet or exercise adjustments.
The 7D-PAR provided a reasonable estimate of both the mean TDEE and PAEE in this sample; however, estimates of energy expenditure on an individual basis using the PAR were subject to considerable error.
Why this rating
Uses doubly labeled water (DLW), the gold standard criterion measure, in a moderately sized sample (N=46) of young adults.
