Description

Study Description: This study will be an outpatient study completed in 3-4 separate visits. We will compare two methods of dosing (fixed and adjusted) a mixed meal tolerance test (MMTT) to determine which results in greater physiological variability in hormone response. Ultimately, the goal is to determine which method of dosing is more appropriate in a research setting. Objectives: Primary Objective: To determine whether an adjusted energy dose MMTT or a fixed dosed meal will result in greater variability in glucose area under the curve (AUC) within the same participants across a range...
