MCGC Nutrition

As a nutritionist-dietitian, my primary goal is to help you acquire better lifestyle habits while maintaining the pleasure of eating. This process of well-being begins with obtaining a structured plan that will allow you to reach your health goals.

My second goal is to be able to offer a totally personalized service that follows the needs and availability of my clients. It is also possible to choose from a variety of services offered; nutritional consultation, grocery store visit, weight management program, diabetes, cardiovascular disease, and much more. I also offer nutrition services not only for individuals, but also for families and businesses.

Breakfast Club of Canada

MCGC Nutrition is a Montreal company dedicated to contributing to the development of our community, especially during this difficult time. This is why we are particularly proud of our new collaboration with ‘Breakfast Club of Canada’.

Why consult ?

In Canada, the title of dietitian is protected like other health professionals. It is used to refer to a person who has received rigorous training from an accredited university, a person who adheres to provincial regulations and who has a valid license number. In the event of a food / health problem, it is therefore recommended to consult a professional with training in this area rather than a nutrition coach.

Instead of focusing on weight, it is more about adopting a balanced diet and long-term healthy lifestyle habits. We can work together towards a positive relationship with food at your own pace. My goal is to allow you to keep your favorite meals while aiming for healthy moderation.

There can be many symptoms of digestive disorders such as feeling heavy, overflowing, bloating, constipation, nausea, gastric reflux, gas and many others. The precise causes of these symptoms are varied and together we can discuss the most appropriate dietary strategy to overcome this discomfort.

More than one in four Canadians live with diabetes. Uncontrolled diabetes leads to a systematic rise in blood glucose levels (hyperglycemia) and can lead to serious complications including cardiovascular disease, vision loss, kidney failure, nerve damage and amputations. Therefore, it requires appropriate management, including monitoring of eating habits and nutritional strategies to keep blood glucose levels under control.

Half of Canadians (52%) 20 years of age and older live with a chronic disease and 1.3 million Canadians live with heart disease. Healthy eating can influence several risk factors such as cholesterol, high blood pressure, weight and waist circumference, and blood sugar levels. If you think you may be suffering from such a disease, we can look at the alternatives together and adopt the most optimal strategy to overcome the problem.

Eating well to meet nutritional needs during sport is important! Together we will discuss performance-enhancing foods, recovery after training, prevention of dehydration and many other topics.

Do not hesitate to contact me about whatever your problem is related to nutrition, we can discuss together and find a solution to simplify your life. You can also take a 20 minute session with me for free to ask me your questions and discuss your concerns.
