Medical Advisory Board
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.
Allan N. Spreen, MD
Dr. Spreen was in private family practice for 10 years, concentrating on nutritional therapies for patients who preferred alternative options to traditional allopathic techniques. He has written two books on the subject of alternative and complementary medicine: Nutritionally Incorrect, and the bestselling collaboration Smart Medicine for Healthier Living, with Janet Zand. Increasing popularity of 'The Nutrition Physician' also led to assignments as a nutrition expert for 'America Online' and 'iVillage-The Women's Network, followed by positions on the medical review board of the Discovery Health Channel and the Health Sciences Institute. He remains active today in the medical field through articles, books, directorships, and custom supplement formulating.
Arthur "Buster" Browning, MD
As a physician, I see the impact of excess weight on a person's life and health. After 34 years in practice, I know that weight loss is about much more than simply changing eating habits. Metabolic Research Center provides the nutritional advice, expertly designed weight-loss menus, one-on-one support, motivation and the education a client needs to be successful. I know firsthand the consultants at the centers are knowledgeable, supportive and encouraging. The program helped me lose weight, regain control of my eating habits and feel good again. That's why I accepted the position as MRC Medical Director 25 years ago, because I believed in the program and knew that it was safe and medically sound.
Larry Siegel, ARNP
As a nurse practitioner, I have personally seen the negative effects of being overweight. A graduate of the University of Florida, I have been in the nursing field for more than 10 years. Working eight years in intensive care units, I have witnessed the end result of multi-system disease, caused by obesity. I am blessed to be a part of the Metabolic Research Center and help fight the obesity epidemic in America, which now affects approximately 60 million people in the United States. I have made it my passion and personal goal to help patients win the battle against weight related diseases. I am a member of the American Society of Bariatric Physicians, American Academy of Anti-Aging Medicine and American Academy of Nurse Practitioners. This enables me to treat patients with the latest weight loss modalities. I am proud to work on the MRC Medical Advisory Board as its chief medical officer, as well as in the centers helping patients achieve their weight loss goals.
