Why medical Weight Loss ?

Overweight and Obesity are complex conditions that may occur as a result of multiple genetic and environmental factors. In many cases, weight gain can be related to conditions such as PCOS, diabetes sleep disturbances, arthritis, stress, anxiety, depression, financial distress, adult ADHD among others, however, this connection is often not made. When these conditions are not addressed, many people are unable to maintain or lose weight. Whether you are looking to lose weight or maintain your weight, our multidisciplinary team will work with you to provide weight loss services to ensure that all aspects of health involved in the accumulation of excess weight have been addressed.

We offer the following services:

Lifestyle Program

Our medical weight loss program is mostly covered by OHIP and involves a comprehensive medical evaluation which is conducted upon enrolment. Dr. Soto  and the team may conduct a medical history, physical examination,  comprehensive fitness assessment, metabolic test measures, body composition analisys,  laboratory tests as well as specialist referrals (if required).

Our medical approach to the accumulation of excess weight includes regular one-on-one visits with our physicians who have a clinical interest in obesity medicine and are experienced in the prevention, diagnosis and management of obesity and related complications. They will discuss with you and the other team members, treatment options that can optimize your weight loss efforts.


The OPTIFAST Program is a medical weight loss program that closely monitors and assesses progress towards a better heath and emotional well-being. The advantage of the Program is that you are provided with a high-quality, calorie-controlled nutritional plan that transitions to self-prepared every day meals while being supported by our multidisciplinary team. Unlike other meal replacements, the OPTIFAST program treats you as a whole person and not just your weight. Unlike fad diets, the OPTIFAST program has been proven effective in more than 80 clinical studies. More than 1 million people have participated in the program since 1974. To learn more about the positive results yielded by clinical studies on comprehensive weight management programs, visit the OPTIFAST website. The OPTIFAST program has been designed for people who have a body mass index (BMI) that is greater than 30 kg/m2. The program utilizes medical, nutrition and behavioral elements to achieve lasting weight loss.

Prescription Medications for weight Loss

Have you tried diet and exercise and have not been able to achieve meaningful or sustainable weight loss? You are not alone. A common misconception is that weight loss should always be the result of a healthy diet and a good exercise routine. While lifestyle changes are an important component of any weight management program, research shows that there are significant biological factors that influence the accumulation of weight in individuals with overweight and obesity. Like in many other medical conditions, prescription medications play an important role in the treatment of obesity along with positive behavioral changes.  The physician will recommend the most appropriate medication for you according to your health history, potential side effects and desired mechanism of action. In Canada, there are three medications approved for long term use for the treatment of obesity.

Contrave® (Naltrexone and Bupropion)

Saxenda® (Liraglutide)

Xenical® (Orlistat)

Metabolic and Fitness Assessment

Take advantage of the first comprehensive metabolic and fitness assessment in York Region

  • Resting Metabolic Rate
  • VO2 Max fitness testing
  • SECA Body Composition Analysis
  • Individualized Nutrition and Fitness Plan

KORR’s proprietary technology was developed to satisfy NASA’s rigorous test standards while meeting their requirements for portability and self-calibration. Our systems use the “gold standard” mixing chamber for capturing expired gases and analysis. This is the same technology used in full-sized hospital-grade VO2/metabolic carts. It is extremely accurate and highly reliable. Mixing chamber analysis is more stable than the gas sampling at-the-mouth testing methods used by many of our competitors.

Resting Metabolic Rate

What is a Resting Metabolic Rate Test?

Metabolism is the process of converting food (calories) into energy. The efficiency with which your body does this is referred to as your metabolic rate. Many factors affect a person’s metabolic rate: weight, age, body composition, hormone levels, and gender making it a highly unique number.

Why Test your Metabolic Rate?

Understanding your body’s unique metabolic rate will allow your health care team to customize your weight loss or maintenance program around your needs. (1) It can screen for a slowed metabolism that may explain frustrated attempts to lose weight in the past. (2) It can reveal changes in your metabolism during the weight loss process that can help trouble shoot a frustrating plateau. (3) Once you reach your goal, an RMR measurement can give you the precise caloric requirement for maintenance to help you sustain your goal weight.

How does the test work?

KORR Metabolic Analyzers utilize the same technology as hospital  metabolic testing. Because every calorie a person consumes requires a fixed amount of oxygen to be converted to energy, the KORR Analyzer measures the oxygen you consume to calculate calories burned. All of the air exhaled by the patient is be collected to measure oxygen consumption. Two one-way valves in the KORR MetaBreather ensure that only fresh air is inhaled and all exhaled air passes through the hose and into the machine.

VO2 Max Fitness Testing

Get the most out of your workout

Each person has optimal training zones. Exercise equipment and charts that tell you target heart rates are actually just averages based on age and weight. The CardioCoach measures your precise target heart rate based on anaerobic threshold, then calculates your unique Target Intensity Zones. These Zones give you the precise heart rates necessary to optimize each level of exercise and maximize your results. With Target Intensity Zones, you’ll work out smarter, not harder!

Decrease Fatigue and Injury

Frequently we push ourselves thinking, “no pain, no gain.” The truth is, pushing beyond one’s optimal training zone leads to fatigue and discomfort. It will also cause increased soreness after the workout and may contribute to exercise related injury. When you know your zones and use them for training, cardiovascular exercise is comfortable. Even a beginner can go the distance!

Burn more FAT!

VO2 testing reveals the exercise level that will optimize a person’s ability to burn fat. The term “aerobic exercise” has been commonly referred to the  "Fat-burning zone". But without VO2 testing, fitness professionals have had to rely on crude estimates to determine what level of exercise intensity would be “aerobic” or fat burning. Now, with VO2 testing readily available, you can know the precise level of intensity that will truly maximize the amount of fat you burn.

How Is A VO2 Test Performed? (It’s as easy as 1-2-3!)

  1. You will be wearing  a heart rate strap and face mask which are connected to the CardioCoach device.
  2. Begin to exercise on our treadmill. Our fitness trainer will perform the VO2 test with you. She will instruct you to gradually increase your intensity over a period of 6 to 20 minutes.
  3. While you can cool down, your Target Intensity Zones are calculated and printed in a simple, insightful report.

Body Composition Analyser

BMI machine

The seca mBCA 514 is a Medical Body Composition Analyzer, which is ideally adapted to the working conditions in hospitals and medical practices. Our non-invasive assessment provides an in-depth analysis measuring fat mass, fat-free mass, total body water and skeletal muscle mass in a rapid 17 seconds.

When you step on a scale and see that you’ve lost 3 pounds, what did you really lose? 3 pounds of fat? Muscle? Water? Measuring your body composition allows you to truly understand the changes in your weight. Knowing how much fat you need to lose and how much muscle mass you are gaining can help tailor your diet and exercise plans to reach your goals. Your body composition analysis is used as a guide to help determine ideal weight and to monitor progress in weight control and/or exercise programs. With this detailed information, we can develop a more personalized exercise and nutrition program.
