If you want the best, come to the best – Idaho Weight Loss

Idaho Weight Loss was the first weight loss center in America with three physicians certified by the American Board of Obesity Medicine.

W. Allen Rader


“I know how losing weight changed my life. I want to help you do the same. In my 16 years in Boise, my team and I have helped over 19,000 patients, including hundreds of doctors and nurses, lose over 546,000 pounds. Many of these patients remain active in our weight maintenance program.

“We talk honestly with the patient and develop and implement realistic goals and maintenance plans when the goal is obtained or weight loss plateaus. If the desired weight loss is not obtained, the doctor and staff will work with the patient to determine what other life factors may be affecting the patient’s progress toward a healthier weight.”

A 1981 honors graduate from the University of Kentucky College of Medicine, Dr. Rader began his practice of obesity medicine in Idaho in December 1999. He was Idaho’s first MD certified by the American Board of Bariatric Medicine and only the 245th nationwide. He has served on the National Board of Trustees for the American Society of Bariatric Physicians and in 2008 was appointed to the executive committee and elected as an officer. He was awarded the National Medical Weight Loss Physician of the Year in 2007 and in 2011 was awarded “Fellow” status for his excellence in obesity medicine. In 2012, he was invited to present his program methods and results at the European Obesity Congress in Lyon, France.

Dr. Rader subscribes to the guidelines of the OMA in caring for patients. He has presented on obesity treatment in 30 states. His experience includes two years as a practitioner in rural Kentucky, one of seven MDs providing care in a 150-bed hospital. His practice included obstetrics, pediatrics, assisting in surgery, general inpatient, outpatient and emergency medicine. For the next 14 years, he cared for patients as an emergency department physician, serving as chairman of the department for seven years. He also served as a state representative to ACEP.

He began his obesity medicine practice in February 1997 in Kentucky before moving to Idaho in December of 1999. His goal today is to provide compassionate, understanding care combined with modern weight loss medicine. Dr. Rader specializes in the treatment of obesity and obesity-related medical and psychological conditions. In his spare time, Dr. Rader enjoys skiing, reading, and playing with grandchildren.

Michelle M. Freshwater

MD, OMA, Diplomate of ABOM

“I started as a successful patient in our weight loss clinic. Finally getting control of my own weight made an incredible difference in my life. I want to help patients find the same success that I experienced. I like being a health partner with my patients. I hope to give them the knowledge and skills to manage their own health.

“The fact that I’ve struggled with my own weight has really helped me relate to my patients. I understand the struggles they’re facing and I draw on my own successes and failures to help them find solutions to their obstacles. I love working with patients who take some responsibility for their choices and actions, and for their success.”

Dr. Freshwater completed her residency training in family medicine at the Via Christi Family Practice Residency program in Wichita, KS. She is board-certified by the American Board of Obesity Medicine and the American Board of Family Medicine. She earned her MD from the University of Kansas School of Medicine in Lawrence and her undergraduate BA in human biology from the University of Kansas. She began patient care with Idaho Weight Loss in July 2005.

Dr. Freshwater is member of the Obesity Medicine Association. She enjoys motherhood, skiing, snowboarding, hiking and camping in the outdoors, as well as knitting and filmmaking with her husband.

Mary Hafer

MD, FACOG, Diplomate American Board of Obesity Medicine

“I chose to go into these fields because my passion is preventive medicine. Both ob/gyn and obesity medicine have a strong focus on helping patients avoid future health problems. I enjoy the continuity of care – following patients through the years and providing care and support.

“I am supportive and solution-oriented, giving my patients the tools and information they need to be their own best health advocate. I am creative and persistent in my quest to find the best options for my patients.”

Dr. Hafer is a board-certified ob/gyn and a fellow of the American College of Obstetricians and Gynecologists. She is also board-certified in obesity medicine by the American Board of Obesity Medicine. She earned her undergraduate BS in biology from the University of Washington, graduating magna cum laude, and her MD from the University of Washington School of Medicine in Seattle. Dr. Hafer completed her residency in ob/gyn at the Medical College of Ohio in Toledo. She began caring for patients with Idaho Weight Loss in January 2007.

Dr. Hafer is a member of the Idaho Medical Association and the Ada County Medical Society. In her spare time, Dr. Hafer enjoys gardening, cooking and nutrition to fuel her downhill skiing, snow shoeing, running, horseback riding and reading historical fiction.

Brad Gilman

MD, member OMA

“I felt I could do more to help people by preventing illness rather than by treating illnesses.

“I love to see the transformations as my patients progress through our program. I love my job as every day I get to participate in people’s lives as they make changes, and I love to hear about the quality of life as it improves.

“I try to become an ally and teammate to the patients and enlist them as partners in the process. At times I act as a coach as well, being positive but pointing out ways to improve. I hope to give them the tools to make changes. I hope to give them a positive example of lifestyle change, positivity and the hope that they can have success doing something that may have been difficult or impossible in the past. Listening skills are a big part of my practice – as well as empathy for people in their struggles. As someone who has lost weight myself, I can relate in this way. I love being creative and approach each patient individually.”

After earning a bachelor’s degree in psychology from Brigham Young University, Dr. Gilman went on to receive his MD from St. Louis University. He completed his internship in emergency medicine and his residency in family medicine at the University of California, Irvine. Dr. Gilman is a member of the Obesity Medicine Association and is pursuing board certification by the American Board of Obesity Medicine. He started providing patient care in obesity medicine with Idaho Weight Loss in January 2008.

In his free time, Dr. Gilman is a member of the YMCA triathlon team and participates in related activities and sporting events. He spends considerable time mountain biking with his wife and three children in Idaho, Utah and Colorado, and he likes to visit Vancouver and Whistler in Canada.

Deb A. Mabbutt

MS, PA-C, Member Obesity Medicine Association

“I enjoy putting the pieces of the puzzle together and developing relationships with my patients. Medicine is not an exact science, and research gives us new information all the time. So my goal is to use it to educate patients and facilitate their progress toward a healthier mind, body and spirit.

“I hope to give my patients the tools to become healthier individuals by being uplifting, encouraging and positive in my interactions with them.”

Deb received her master’s degree as a physician assistant from the University of Utah School of Medicine in Salt Lake City. She did her residency training in family practice medicine in the Treasure Valley of Boise. She also holds a bachelor of science degree in exercise physiology from Boise State University. She started providing patient care with Idaho Weight Loss in August 2010.
