When the subjects vital signs are stable, the study team will also measure percent body fat using a Dual Energy X-ray Absorptiometry (DEXA) and intra-abdominal fat by Magnetic resonance imaging (MRI). When the DEXA scan and MRI tests have been completed, subjects will be discharged from the hospital. Depending on scheduling, however, the DEXA scan and MRI tests may be performed on a separate occasion from the study trial admission.
