This research study plans to learn more about where the fat cells in your body come from. Understanding the origin of fat cells is important because it may help to determine the health of fat cells and why fat that is stored in some places of your body is more "unhealthy" than other fat.
If you join the study, you will complete the following research procedures over the course of 2 study visits: Informed consent, physical exam and medical history, body composition test, blood draw and fat biopsy.
