About Us

WEIGHT2LOSE BACKGROUND

Weight2Lose Clinics started its journey as a medical weight loss and chronic disease prevention and management clinic. Since 2011, our medical doctors, researchers and clinical nutritionists, helped thousands of patients every year successfully lose weight and address the root cause of chronic diseases. Our medical team is helping patients every day suffering from obesity, diabetes, metabolic problems, hypercholesterolemia, enhanced autoimmune activity, inflammation, energy deficits, depression, anxiety and numerous other disorders. Our objective is to stop the growing obesity and chronic disease threat globally, starting with Canada.



HEALTHCARE PROBLEM

The evidence is overwhelming that the root cause of most chronic diseases lies within patients’ lifestyle choices, particularly their daily nutrition habits and lack of physical activity. Despite compelling evidence for the above, our healthcare system is primarily designed to treat patients with medication, without addressing the root cause of the problem. Most medical doctors encounter strict time limitations and lack sufficient training in nutrition and cognitive behavioral therapy and recognize these as significant gaps in their medical training. Consequently, most medical clinics lack adequate resources to facilitate effective weight loss and chronic disease prevention and management programs for their communities.

OUR SOLUTION FOR PHYSICIANS

Most physicians realize the great need for a more systematic approach to nutritional counseling and cognitive behavioral therapy interventions in primary care. Our proven and research supported model of care evolved to provide a seamless integration into any primary care and family practice setting. Weight2Lose offers a proven system for medical doctors and nutrition professionals to effectively collaborate in offering personalized programs that address the key factors underlying chronic disease. At the moment, our main focus is to help physicians across Ontario and the rest of Canada, adopt our evidence based programs and resources for their patients, with the onsite support of Weight2Lose health educators (e.g. registered dietitians, certified diabetes educators, nurse practitioners, etc.) Learn More.



RESEARCH AND PROGRAM DEVELOPMENT

Weight2Lose continuously manages several research studies and maintains close partnerships with academic affiliates (such as McGill University). At the moment, our medical team is researching the effectiveness of several cognitive behavioral therapy interventions, focusing on Emotional Eating and Mindfulness. Our system enables the perfect “marriage” between research and development and application in primary care.
