Natalie R Gillan PhD

Natalie has been working with nutrition and nutritional therapy since 2003. She has extensive scientific expertise in identifying the root cause of her patients’ symptoms.

During her 18 years of clinical practice, Natalie has developed industry-leading expertise across a broad spectrum of patients' needs including, but not limited to:

  • digestive problems including IBS, IBD, SIBO, gastric reflux and food intolerance;

  • weight management, including extensive work with diabetes;

  • bariatric (weight loss) surgery nutritional support; and,

  • hormonal disorders for both female and male patients.

As a bariatric surgery team member, she works with world-class surgeons and psychologists, supporting weight loss surgery patients beyond NHS or private clinics’ care packages.

Her full understanding of the dietary and nutritional challenges resulting from bariatric procedures combines with her therapeutic and coaching skills to fully support and counsel her patients in their pursuit of better health and weight loss. 


Dr Gillan's passion for life is unmistakable in her full-on roles as a professional therapist, culinary artist and multitasking mother. Seasonal selections of locally-sourced clean and sustainable menus are her hallmark.
