What Is Medical Weight Management?
Weight gain is rarely caused by overeating alone. Your metabolism is influenced by a complex network of hormones, insulin regulation, stress, sleep, nutrition, gut health, and lifestyle. When one or more of these systems becomes imbalanced, losing weight can become significantly more difficult, even when you’re making healthy choices.
At Peak Health VIP, our physician-supervised weight management program in Oakville focuses on identifying and addressing these underlying contributors rather than relying on restrictive diets or temporary solutions. By optimizing metabolic balance and improving how your body regulates energy, we help create the foundation for healthier, more sustainable weight management.
Who This Is For
You’ve read the labels. You’ve swapped the snacks. You’ve added the extra gym sessions. And somehow the number on the scale barely moves, or it’s actually gone the wrong direction.
- You’re eating less than you used to and still not losing weight.
- Your clothes fit differently even though your routine hasn’t changed.
- You’re tired in a way sleep doesn’t fix.
- Your last bloodwork came back “normal,” but nothing about how you feel is normal.
- You’ve started to wonder if this is just what it’s like now.
This is for you if:
- You want a real answer for why your body stopped cooperating, not another meal plan.
- You’re navigating perimenopause, menopause, or andropause and gaining weight you can’t explain.
- You suspect your thyroid, blood sugar, or stress hormones are part of the picture.
- You’ve tried GLP-1 medications and didn’t get the results you expected, or regained weight after stopping.
- You’re ready to see a weight management physician instead of trying another generic program on your own.
- You want to build something that lasts, not lose the same ten pounds every year.
If any of this sounds familiar, you don’t need more willpower. You need to know what’s actually going on.
This is for you.
4-Step Medical Weight Management Method
You Don’t Need Another Crash Diet.
You Need a Strategy Built Around Your Biology.
Our physician-supervised medical weight loss programs combine advanced diagnostics, metabolic optimization, and personalized medical care to help you achieve sustainable results while improving your overall health.
Step 1:
Discover the Root Causes
We begin with a comprehensive assessment to understand the factors influencing your weight.
Dr. Mark’s methodology includes:
- Comprehensive medical history
- Lifestyle and nutrition assessment
- Advanced laboratory investigations, which may include complete blood count, kidney and liver function, fasting glucose, HbA1c, fasting insulin, lipid profile, thyroid function, cortisol or adrenal assessment, sex hormones, ferritin and iron studies, vitamin B12, vitamin D, and other relevant vitamin and mineral levels
- Hormone and metabolic evaluation
- Body composition assessment

Not every patient requires every test. Testing is selected based on your symptoms, history, risk factors, and treatment goals.
You may benefit from:

- Nutritional recommendations and targeted supplements
- Sleep and stress support

The Truth About Weight Loss
What Happens When Weight Loss Is Treated Like a Willpower Problem
Patients tell us they’ve been told things like:
- “Just eat less and move more.”
- “Everything on your bloodwork looks fine.”
- “It happens to everyone as they get older.”
- “Have you tried a different diet?”
- “There’s a pill you could try for your appetite.”
- “There’s nothing medically wrong here.”
Why Weight Management May Need a Closer Look
| A Standard Assessment | May need additional evaluation of thyroid function, insulin resistance, hormonal changes or persistent gut symptoms. |
| “Normal” Range Labs | Results within the reference range need to be interpreted alongside your symptoms and medical history. |
| A New Diet Plan | May be insufficient when untreated thyroid symptoms, insulin resistance, or digestive symptoms also need attention. |
| Appetite Suppressants | Can help regulate appetite, but do not replace assessment of coexisting hormonal changes or gut conditions. |
| “It’s Just Aging” | Menopause, stress and disrupted sleep can influence weight. |
We Believe
As a dedicated weight management clinic in Oakville that patients turn to, we look beyond standard screening to evaluate potential metabolic, hormonal, gut-related, and lifestyle contributors, then build a personalized plan to address them.”

Frequently Asked Questions – Weight Management
Who is eligible for medical weight loss programs?
The program is a good fit for women and men who have struggled to lose or maintain weight despite reasonable efforts, including diets, exercise programs, or not responding to or regaining weight despite GLP-1 medications such as semaglutide or tirzepatide. It may not be appropriate for individuals who are pregnant or breastfeeding, have an active eating disorder or unstable medical or psychiatric condition, require urgent or specialist care, or are seeking medication without completing a comprehensive medical assessment. A weight management doctor will perform a comprehensive assessment to confirm the most appropriate approach for you.
When will I see results from my weight loss program?
Results from your weight management program in Oakville vary based on your metabolism, underlying health conditions, treatment plan, and lifestyle changes. Many patients notice improvements in energy and overall well-being early on, while healthy, sustainable weight loss typically occurs gradually over time.
Will the weight come back after treatment?
Long-term success depends on maintaining healthy habits and addressing the factors that contributed to weight gain. Our medical weight loss programs focus on sustainable lifestyle changes and ongoing physician support to help you maintain your results and improve your long-term metabolic health.
Are weight loss programs personalized for each patient?
Yes. Every patient receives a customized treatment plan based on a detailed medical evaluation, laboratory testing when appropriate, lifestyle factors, and personal goals. Our weight management physician develops recommendations tailored to your unique physiology rather than following a one-size-fits-all approach.
Do you prescribe GLP-1 medications for weight loss?
We may prescribe GLP-1 medications when medically appropriate following a comprehensive assessment. These aren’t automatically recommended to every patient. They’re one potential component of a broader strategy that also addresses your metabolic health, hormones, nutrition, activity, sleep, stress, and gut health.
How long does the program take, and how many visits are involved?
The program begins with a comprehensive medical assessment, followed by laboratory testing and a review-of-findings appointment. A personalized treatment plan is then developed, with regular follow-up appointments to monitor progress, review symptoms and laboratory findings, and adjust treatment as needed. The exact duration, number of visits, and follow-up schedule are customized to your medical needs, goals, and progress, though the typical program lasts 6 to 9 months and includes approximately 5 to 7 visits.
Is this safe / are there side effects?
Patient safety is always our priority. Before beginning weight loss treatment in Oakville, your physician reviews your medical history, current health, and treatment options to determine the safest approach. Any potential risks or side effects are discussed beforehand, and your progress is monitored throughout treatment.
What testing is involved before starting?
Testing is personalized to your medical history, symptoms, medications, previous results, risk factors, and treatment goals. It may include complete blood count, kidney and liver function tests, fasting glucose, HbA1c, fasting insulin, lipid profile, thyroid function, cortisol or adrenal assessment, sex hormones, ferritin and iron studies, vitamin B12, vitamin D, other relevant vitamin and mineral levels, body composition assessment, and a review of sleep, stress, gut symptoms, lifestyle, and nutrition. Not every patient requires every test.
Does OHIP cover weight loss?
Our private weight management program is not covered by OHIP. Some laboratory testing may be covered when medically indicated, while expanded or specialized testing may be uninsured. We will explain any applicable fees before proceeding.
What is medical weight loss and how is it different from dieting?
Unlike traditional dieting, medical weight loss programs are physician-supervised and designed to identify and address the underlying medical, hormonal, metabolic, and lifestyle factors contributing to weight gain. This personalized approach supports healthier, more sustainable long-term weight management rather than short-term results.
Is weight management different for men and women at Peak Health VIP?
Yes. Men and women experience different hormonal changes, metabolic patterns, and health concerns that can influence weight management. Our weight management doctor develops personalized treatment plans based on your physiology, medical history, and long-term health goals rather than using a standardized approach.
What if I’ve already tried diets, medications, or other clinics without success?
Many patients visit our weight management clinic in Oakville after trying diets, medications, or commercial programs without lasting results. Our weight management physician focuses on identifying underlying metabolic and medical factors to develop a comprehensive, physician-supervised treatment strategy tailored to your individual needs.
