Medical Director

Dr. Yoni Freedhoff MD, CCFP

Dr. Yoni Freedhoff MD, CCFP graduated with honours from the University of Toronto medical school where he received the Betty Stewart Sisam award, given to the graduating student who, "has shown the greatest human understanding and care for the welfare and health of patients".

Very early in his medical career Dr. Freedhoff realized that the medical community, himself included, was not adequately managing obesity. Though many patients requested weight-loss advice he had very little to offer as the management of obesity is simply not taught during medical school or during medical residency.

Consequently, Dr. Freedhoff pursued training from the American Board of Obesity Medicine (ABOM), the only medical organization in North America to offer certification in Bariatric medicine, and in March of 2005 he became the third physician in Canada to receive their board certification. In 2007 the Canadian Obesity Network recognized him as a national obesity expert and in 2010 he served as their inaugural Family Medicine Chair.

Since dedicating his professional career to the treatment and management of overweight and obesity, Dr. Freedhoff has been a sought after speaker and teacher. In 2011 the University of Ottawa appointed him an Assistant Professor of Family Medicine and he regularly supervises both medical students and residents in his office. For a list of his most recent speaking engagements, scroll down to the bottom of the page.

Dr. Freedhoff has been referred to as Canada's most outspoken obesity experts and the Canadian Medical Association Journal once dubbed him a Canadian "nutritional watchdog". His advocacy efforts in both obesity and nutrition policy have landed him speaking at the Canadian House of Commons regarding his concerns surrounding Canada's Food Guide and as a member of multiple stakeholder groups run by the Public Health Agency of Canada and Health Canada. In 2010 Dr. Freedhoff helped to co-found Reality Coalition Canada, a non-profit group of diverse Canadian experts whose mission is to promote evidence-based obesity prevention and treatment policies and messages.

Dr. Freedhoff is quoted regularly in the national and international press, appears frequently on television including a regular spot on CTV's Social and appareances on NBC's Today Show, the BBC's The Men Who Made Us Thin, CTV, CBC, the A Channel, and he has made more guest appearances on CBC's investigative journalism show Marketplace (six) than any other of their content experts.  Dr. Freedhoff's award winning blog, Weighty Matters, has at times been ranked the world's top health blog by blog ranking service Technorati.  Not content with just his own blog, Dr. Freedhoff also writes a weekly column for US News and World Report and is a guest blogger for both Psychology Today and the Huffington Post.

In an effort to help his colleagues learn more about how to help their patients with weight management, Dr. Freedhoff co-authored a medical textbook on the office-based management of obesity, Best Weight: A practical guide to office-based weight management which is available at online booksellers and at the insistence of Drs. Freedhoff and Sharma, available freely for download from the Canadian Obesity Network.

Dr. Freedhoff's first book for the public, The Diet Fix: Why Diets Fail and How to Make Yours Work, is a #1 National Canadian bestseller and a Heather's Pick, and is availalbe at bookstores and online.
