Study Summary
This study will look at gene expression (whether particular sets of genes are activated \["turned on"\] or deactivated \["turned off"\]) in overweight people as compared to non-overweight individuals. It will also investigate the potential role of inflammatory and protective substances that are produced naturally by the body within fat tissue. Findings from the study may lead to the development of ways to predict who will respond best to diet therapy. Healthy individuals between 25 and 45 years of age may be eligible for this study. Overweight subjects must have a BMI of 25 to 40, and non-overweight control subjects a BMI of 19 to 24.9. Candidates are screened with a medical history, physical examination, blood tests and electrocardiogram (EKG). They are instructed to record their dietary intake for a 3-day period and to collect their urine for a 24-hour interval. Participants have their food records reviewed a week after the screening visit. They are then scheduled for an overnight admission to the Clinical Center. Non-overweight subjects have one or two inpatient stays; overweight subjects have six inpatient stays plus frequent nutrition counseling sessions. During the 2-day hospital admissions, the following studies are performed: * DEXA scan to determine the percentage of body fat tissue. The subject lies on a table for about 15 to 60 minutes while the body composition is measured with very low-dose x-rays. * Single-slice CT scan to compare the amount of fat tissue under the skin with that in the abdomen. The subject lies on a table for about 5 to 10 minutes while the CT scanner measures body composition with very low-dose x-rays. * Subcutaneous fat microdialysis to investigate how weight loss affects the activity of fat tissue. A small tube (catheter) is placed into the fat tissue under the skin of the abdomen after numbing the skin with a local anesthetic. Fluid samples are collected through the tube. The procedure lasts overnight. In five non-overweight co
