Purpose:

The purpose of this study is to characterize differences in the structure and function of the body fat from two different parts of the body in young, healthy men and women. We will also compare how differences in metabolism relate to characteristics of body fat and its functions.


Study summary:

Following screening, the study comprises of a total of 3 clinic visits (2 outpatient visits, and 1 overnight stay) completed during a 2 week period. For the outpatient visits, body composition (by DEXA), visceral fat (by CT), ectopic fat (by MRS and CT) and aerobic fitness (by VO2max test) will be measured. Women will also have ovarian parameters (follicle size and number) measured during the MR scans. Following an overnight stay in the inpatient unit, insulin sensitivity (by euglycemic hyperinsulinemic clamp), interstitial lipolysis (by microdialysis), whole body lipolysis and glycolysis (by stable isotopes), abdominal adipose tissue oxygen content (Hunt and Direct Methods) will be measured and a subcutaneous fat biopsy of the abdominal and gluteo-femoral tissue will be collected. Women will complete all testing in the follicular phase of the menstrual cycle.
