Optimizing Meal and Snack Timing to Promote Health

This study will be conducted using standardized techniques to collect blood samples via an acute, randomized, cross-over design. Subjects will be provided all of their meals the day prior to testing and participate in 3 testing days with a minimum of 1 week break between testing days and a maximum time commitment of 7 weeks. A trained phlebotomist will place a catheter and collect blood samples from an antecubital vein using sterile techniques.
