The Bariatric Medical Institute (BMI) is a multi-disciplinary behavioural weight management program. BMI does not use specific diets, drugs, products or supplements in its approach but rather helps patients lose weight through education, motivation and support.

BMI receives direct referrals from local physicians, the Ottawa Hospital's Eating Disorder program, the Ottawa Heart Institute and others, however patients may also choose to refer themselves.

The focus at BMI is on the creation of a sustainable lifestyle, free of the traditional suffering of dieting, leading to gradual, healthy and permanent weight loss.
