About John Cartmell, MS



John W. Cartmell was born and raised in Washington State. He has been a Licensed Massage Practitioner in Washington since 1985, and a Certified Nutritionist since 2004, receiving a Master of Science degree in Nutrition Research from Bastyr University of Natural Medicine in Kenmore, WA. He did his master's thesis on "Nutrition in Fibromyalgia".

The Diet Advisor website was founded in 1998 to help clients promote better health through improved nutrition and lifestyle. By analyzing age, weight, gender, lifestyle,  diet, digestion, supplements, medications, and general health status, he identifies the client's nutritional strengths and weaknesses and provides recommendations on how best to promote optimal nutrition and health.

He became interested in nutrition during premed studies at the University of Washington in the early 1970s. Since then, he has been an advocate of proper nutrition, seeking to better understand the balance of health and the imbalance of disease.
His interest and experience in nutrition now spans more than forty years, during which he applied his vast knowledge of nutrition to help recover from 3 major health problems.

In 1984 he was diagnosed with leukemia, and cured four years later by a bone marrow transplant. He credits dietary revisions during and after the transplant for his survival and recovery, where 95% of other patients perished during the transplant.

In the mid 1990s, he developed symptoms of Chronic Fatigue, and Fibromyalgia, a soft tissue condition that causes widespread pain. He recovered his health after resolving a digestive problem.

In 2003, diverticulitis led to bowel injury and peritonitis during an episode of heavy lifting. While reintroducing foods after surgery, he discovered several food sensitivities that had contributed to bowel inflammation. Addressing these concerns helped restore normal health and prevent further digestive disturbances.

With the arrival of middle age, he has gained personal experience with age-related issues of inflammation, maldigestion, weight gain, increased blood pressure, memory problems and fatigue -  increasing his overall knowledge and ability to help others.

As a Certified Nutritionist, he specializes in clinical nutrition, helping to address specific nutritional needs in people with Diabetes, Heart Disease, Cancer, Arthritis, Chronic Fatigue, Fibromyalgia, Immune Disorders, and other chronic or age-related conditions of ill-health..

Although his office is in Redmond, WA, he has also helped clients nationwide and sometimes worldwide improve or recover health. Phone consultations are available at no extra charge.

He has been a speaker for area service clubs since 2006, and has published papers and letters on health and nutrition in several professional journals. His book, “Fibromyalgia, a Nutritional Approach to Prevention, Treatment and Cure”, was published in digital form in 2008 and is available on Amazon.com.

John W. Cartmell is an in-network provider for Premera Blue Cross, Regence, Cigna, Aetna, Whole Health Network, and First Choice Health including plans by Corvel, Group Health Options, Alliant, and Medicare Part B. Other health plans may also provide benefits for nutritional services.
