I have been a dietitian for over 35 years and have provided nutritional counselling for various medical conditions in a hospital setting and in private practice. I strongly feel that weight management is an important health issue as it can prevent chronic diseases such as diabetes, heart disease and cancer. It is never too late to change your food habits. Fad diets may help you lose weight initially but they are not sustainable longterm. I will guide you to follow easy and practical meal plan to achieve a healthy weight without 'chronic dieting'. Make 'healthy weight' your goal for 2026.

As a registered dietitian I take an anti-diet approach to support my clients. Growing up as a "picky eater", I was always told how to eat and how much to eat. As I got older, I grew an interest for food and nutrition which led me to become a registered dietitian. Now I support individuals in creating sustainable dietary changes based on their preferences, dietary restrictions and medical history. I believe that embracing cultural foods, enjoying all foods and meeting your nutrition needs can all be done in sync. I specialize in pediatrics, women's health and family nutrition.

Do you feel stuck in cycles of dieting, food rules, or ongoing anxiety and guilt around eating? You may find yourself preoccupied with what, when, or how much to eat, alternating between restriction and feeling out of control. Eating might feel stressful, confusing, or something you have to constantly manage rather than something your body can guide naturally. Many clients want to step away from this cycle—to feel more at ease with food, more connected to their body, and more confident in their eating without relying on rigid rules or constant willpower.

Food Sensitivity Nutritionists and Dietitians
What is a food sensitivity?
A food sensitivity is a condition where an individual has difficulty digesting certain foods, leading to symptoms such as abdominal pain, bloating, diarrhea, and rashes. The exact causes of food sensitivities are not well understood, and the symptoms and triggers can vary greatly from person to person. However, some foods are more likely to cause sensitivities, including gluten, soy, eggs, dairy, and certain food additives like artificial colors and sweeteners.

What is the difference between a food sensitivity and a food allergy?
Food allergies involve an immediate immune system response to a specific food, while food sensitivities result from the digestive system reacting to certain foods. Although both can cause similar symptoms, such as rashes and abdominal pain, allergic reactions typically occur much faster than sensitivity reactions. Allergic reactions can happen as soon as the allergen is ingested, whereas food sensitivity symptoms may appear 24-48 hours after consuming the triggering food. In severe cases, allergic reactions can impair breathing and require immediate medical attention, whereas food sensitivities rarely affect the airway and usually do not need urgent care.

Can food sensitivities be cured?
Currently, there are no definitive treatments for food sensitivities. Unlike food allergies, which children can sometimes outgrow or treat with early exposure to allergens or immunotherapy, food sensitivities do not generally respond to these methods. Thus, the best way to minimize symptoms is usually to avoid the foods that trigger symptoms. In rare cases, food sensitivities may resolve on their own, but, for most people, avoiding the problematic food is the only effective long-term way to manage symptoms.

Should I get food sensitivity testing?
There is little evidence to support the efficacy of food sensitivity testing. Unlike food allergy testing, which measures the body's immune response to certain foods, there are few reliable methods to assess the digestive distress associated with food sensitivities. Individuals experiencing symptoms of food sensitivity but unable to identify the triggering foods, however, may benefit from elimination diets. These diets involve cutting out certain foods to determine which ones cause symptoms. Identifying the problematic foods allows individuals to avoid them in the future, ideally eliminating their digestive issues.
