Dr. Peter Goldfarb

As a practitioner of family medicine in Toronto, Dr. Goldfarb has an established 40-year history in patient care.

During his first 12 years of practice, Dr. Goldfarb increasingly realized the dire need for a sensible approach to significant weight loss. After researching the marketplace, he chose OPTIFAST® and began offering it to the pubic in 1990. As a weight loss coach and insightful counselor, he has assisted over 2000 people.

He feels that OPTIFAST® works, and that it represents a safe and healthy alternative to those who need to lose a significant amount of weight and who want to learn how to keep it off.


What is essential to this program, and the reason it works so well, is that it is individualized to each patient. It is tailored to every patient’s specific situation, weight loss goals, and co-existing health problems. As well, it is conducted on a one-on-one basis with Dr. Goldfarb at his Toronto office. This way, any concerns that arise along the way are discussed and worked through.

Dr. Goldfarb has made a commitment to this program and the individuals interested enough to embark upon it. He invites those involved to keep seeing him, regardless of their program status.

His overriding desire is for his patient’s long term health and happiness.

Dr. Goldfarb’s medical degree is from University of Toronto. After spending several years in research and surgery, he decided on family medicine because of the opportunity to relate to, and care for, people in a more direct fashion.

Get started with our Body Mass Index (BMI) calculator.

BMI determines your risk for weight-related health problems by using your height and weight values to arrive at a representative number.

As a person’s BMI increases, so too does their risk for acquiring weight-related diseases. OPTIFAST® is suitable for those with a BMI greater than or equal to 30. It may also be appropriate for individuals with a BMI of 27 – 29.9 who have other medical problems caused by their weight. A person’s BMI is the means by which one’s eligibility for the OPTIFAST® weight loss program is determined. The Body Mass Index (BMI) calculator calculates your score.

Dr. Goldfarb’s OPTIFAST® weight loss program can help you achieve feelings of mastery, empowerment, and happiness that come as you gain control of your weight.
