Robert Dent, MD, FRCPC

“Obesity is the last frontier in discrimination” is a quote often made by Dr. Dent. As a pioneer in the field of bariatric medicine and the treatment of obesity, Dr. Dent realized long ago that obesity is a disease. While society has a tendency to marginalize or blame individuals for weight issues, he understood that there were genetic and environmental factors at play. Dr. Dent began the first medically supervised weight management program in Canada and has supported patients towards improving their health and wellness since 1992. His team-work mentality and passion for research has resulted in over 50 publications.  Dr. Dent has collaborated with the University of Ottawa School of Medicine to provide sensitivity training, medical training, resident electives and in 2013, the first Bariatric Medicine Fellowship. Dr. Dent is on the cutting-edge of ground-breaking research in genetic obesity including the diet resistance phenomenon and measuring gene expression products in whole blood.

Judy Shiau, MD, FRCPC, DipABOM

Dr. Shiau’s goal is to provide comprehensive care for patients who are trying to be at a healthy weight. As a general internist, her specialty initially focused on the treatment of cardiovascular disease, diabetes, cholesterol, and hypertension. She soon realized that many of these health issues were linked with weight management and this was the stimulus for her to develop the EMERALD (Evaluation of the MEtabolic syndrome for the Reduction of Atherosclerosis, Lipids, and Diabetes) weight management program at the Ottawa Cardiovascular Centre, treating over 1,000 patients from 2002 to 2012. In 2012, she joined The Ottawa Hospital Weight Management Clinic (TOH-WMC) to help support the Ontario Bariatric Network (OBN) funded medical and surgical weight management programs. However, recognizing the need for a community-based clinic to support patients, Dr. Shiau founded the LEAF Weight Management Clinic.

Dr. Shiau graduated medical school from McGill University, completed general internal medicine residency training at McMaster University, and her fellowship year at the University of Toronto. She is certified as a Diplomate of the American Board in Obesity Medicine. As an Assistant Professor and Bariatric Medicine Fellowship program director at University of Ottawa, she trains future generation physicians how to better help their patients who have weight issues.

LEAF stands for Live.Eat.Activity.Forever. The nature and nurture theme is reflected in the names of all program options available at LEAF. The reason for this theme is to reflect the balance of genetics and world we live in with respect to weight management. Dr. Shiau has a strong interest in program development for different populations trying to manage their weight and hopes that patients will find support within the LEAF programs.
