Stanley K. Bernstein is a Canadian physician who founded and is the current owner of 60 weight-loss clinics in Canada known collectively as the Dr. Bernstein Diet & Health Clinics. Bernstein has owned and operated weight-loss clinics since 1974 and employs a weight-loss regimen involving a low calorie intake, frequent physician visits and injections of a Vitamin B solution. Bernstein is a member of the American Society of Bariatric Physicians. Early life and education Bernstein was raised near the Moss Park area of Toronto by Polish immigrant parents who owned a used clothing outlet called Bernstein's Second Hand Store on Queen East. Bernstein graduated from the University of Toronto in 1966 and followed this by interning at Mount Sinai Hospital in Toronto. Career Establishing the Dr. Bernstein Diet & Health Clinics After completing his internship, Bernstein set up a general family practice in 1967 near Gerrard and Greenwood in Toronto, and was also involved in geriatric work at Baycrest Centre. In 1972, Bernstein traveled to Las Vegas to attend a conference hosted by the American Society of Bariatric Physicians. It was at this conference where Bernstein learned about a group of physicians who were using what was called the Simeons Approach as a way to help patients achieve weight loss. In order to achieve weight loss, the Simeons Approach prescribed a very low-calorie intake and injections of a hormone called Human Chorionic Gonadotropin, or hCG, a hormone produced by pregnant women to break down fat stores thought to feed the baby. Bernstein returned to Toronto and began using this knowledge to treat patients at his practice by helping them achieve a state of Ketosis. Subsequently, Bernstein opened his first dedicated weight-loss clinic at the Richmond-Adelaide Centre of Toronto in 1977 and in 1978, his second clinic in Toronto's Yorkville neighbourhood and his third in 1978 at Yonge and Eglinton, also in Toronto. By the early 2000s, Bernstein had 14 diet clinics in Ontario. Over the next few years, his practice expanded to Ottawa, Vancouver, Edmonton and Calgary. Around 2005, Bernstein opened his first American clinics in Virginia and Florida. As of 2010, Bernstein owned and operated 62 clinics across Canada, treating nearly 10,000 active patients. It is estimated that Bernstein's clinics have treated approximately 450,000 patients over the years, including Canadian Archbishop Marcel Gervais and comedian Mike Bullard, who appeared in company advertisements for a period of time.
