Lesley Nickleson

Dietitian

Lesley Nickleson is a Board-Certified Integrative Functional Nutrition Dietitian and one of few practitioners in Canada to hold IFNA board certification. With 28 years of clinical experience as a Certified Nutrition Support Specialist, her background spans critical care, oncology and integrative practice.
 
Over nearly three decades of clinical practice, her work has evolved into refined expertise in identifying patterns that influence sustainable health outcomes. Advanced training in Integrative Functional Nutrition elevated her approach beyond conventional disease-based care, to highly personalized root-cause nutrition strategies. Lesley believes nutrition holds profound healing potential when targeted nutrients are aligned with systems in the body to restore balance and optimal function.
 
In addition to nutritional science, Lesley is a Certified Meditation and Mindfulness teacher and qualified Mindfulness Based Eating Instructor (MB-EAT). Her work integrates functional nutrition with nervous system regulation, recognizing that healing extends beyond food alone.
 
After supporting thousands of individuals with complex health and root-cause imbalances, Lesley has transitioned her embodied clinical wisdom into the Nutrition Solutions Collection - a growing library of transformative, nutrition and lifestyle protocols developed from real client experiences and real-world results.
 
She is now focused on expanding her work through writing, education and program development designed to translate decades of clinical insight into scalable systems for meaningful impact.
 
Her work is grounded, innovative and committed to bringing clarity, structure and depth to modern healing.
