Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

You are invited to take part in a research study about the role of leptin (a fat cell hormone that normally circulates in the blood) on maintaining a reduced body weight. This study will also evaluate how leptin impacts hormone levels, metabolic rate (how many calories are used at rest), autonomic nervous function (the part of your brain that controls your heart rate and breathing), changes in body composition and your sense of appetite. Under normal conditions, leptin is secreted by fat cells and signals to the brain to decrease appetite and regulate energy usage and hormone levels. When obese individuals lose weight, their leptin levels go down, which may cause them to later regain the weight. This study will provide leptin as an investigational medication (not yet approved by the Food and Drug Administration) to increase the levels of the leptin hormone that normally circulates in your blood back to a normal range. We will see if this can help you to maintain your reduced body weight and improve your hormonal and metabolic function.
