About this study

Monitoring free-living lifestyle behaviors can provide important information on behavioral determinants of health. New technologies have improved accessibility of ambulatory assessment of diet, biomarkers, physical activity, and sleep. The study will assess the effects of free-living diet assessed by questionnaire and sleep and physical activity measured by actigraphy on interstitial glucose measured by continuous glucose monitoring in healthy adult men and women over a 2-week period.
