Hi! I'm Inderpreet, a bilingual Registered Dietitian with a focus on PCOS, ADHD, hormone health, GLP-1 medication nutrition, weight management, and South Asian diets. I believe that nutrition is more than just "hitting macros". Through my clinical experience, I've seen how closely food, physical and mental health are intertwined. You need someone who will consider both your nutrition and mental health, or else diet changes won't stick! Supporting close friends and family with PCOS and ADHD has deepened my understanding of how challenging it can be to live with these conditions while juggling everyday life.

As a Registered Dietitian specializing in sports nutrition and eating disorders, my approach is to optimize athletic performance, address disordered eating behaviors, and support individuals in achieving their goals, all while using intuitive and mindful eating approaches. Coming from a multicultural background and being an immigrant to Canada, I bring a unique perspective that recognizes and respects various dietary practices and cultural food traditions. Having gone through my own personal health journey, I vividly remember the first time I saw a registered dietitian myself and left feeling unheard.
