We Stand Behind the Research in Metabolic Research Center

Metabolic Research Center's weight loss programs were created by board certified physicians, research scientists and registered dietitians who wanted to design medically sound, evidence based weight loss programs which allow individuals to maintain a healthy lifestyle. We approach the science of weight loss and weight management from a clinical, research-based perspective. Our programs are based on decades of scientific research in the fields of medicine and nutrition. We strive to provide excellent customer service through personalized weight loss programs with a focus on supporting our client's health. It is our goal to stay current with the latest research related to weight loss, psychology, hormones and nutrition. Our Medical Advisory Board is comprised of a wonderful group of experts in all of the areas that impact your weight loss journey, including board certified physicians, registered dietitians, nurse practitioners and licensed clinical social workers. Our 70+ weight loss centers are individually owned and operated throughout the United States.
