Anxious, depressed, or feeling like your energy and emotions are all over the place? Is food a source of comfort when feeling stressed, bored or overwhelmed? Maybe you are caught in a binge-restrict cycle, resulting in constant food noise and a strained relationship with food, body image, and weight. If so, you are not alone. With the right strategies that account for your unique neurophysiology, it’s possible to be in control of your mental and physical health and feel like the best version of yourself. Empowerment starts by working with your mind, not against it.

Maybe you're miserable with pregnancy side effects, anxious about starting solids with your baby, or stressed about feeding your picky toddler. Maybe you've had bloodwork done, and you're feeling motivated to lower your cholesterol or prevent a chronic disease. You might be interested in working towards a plant-rich diet (vegan, vegetarian, or flexitarian) without compromising on nutrition. Or you might need support in leaving behind diet culture to rebuild a healthy, peaceful relationship with food.

I work virtually with motivated individuals or couples (in Ontario) who are actively trying to conceive or planning for pregnancy. They seek evidence-based information and personalized guidance to optimize their fertility and prenatal nutrition. With concerns about their current diet, lifestyle choices, or specific medical conditions, they are driven to provide the best start for their future child. They value the role of nutrition in this process and are open to making positive changes. Ultimately, their goal is to create a healthy, nurturing environment for their little one to thrive.
