To get solutions to real life problems, we need real data – not “perfect” data.  Your unusual days are just as valuable as your usual days – this is the real-world data that is greatly needed for research!  We encourage you to report your diet and activity as accurately and authentically as you can.  This study is designed to account for variations in your routine.  You will have the opportunity to report your diet and activities a few times over the course of the year.  This will help provide a more accurate picture for your overall routine, even if you had an unusual day.
