Jessica Begg - Registered Dietitian, Nutritionist, Calgary

Jessica Begg, Registered Dietitian, excels at helping others make significant, healthy changes.  She uses strategies that are reasonable in real life and sustainable over time.  Described by her clients as their “Food Therapist”, she guides them towards a fearless and natural relationship with food.  Her specialty is ‘food and mood’ and how to navigate the relationship so that it does not hinder quality of life.

She has worked in the field of Eating Disorders, since 2006. She has worked with both youths and adults, in the Vancouver Coastal Health Eating Disorders Program for 9 years, the Fraser Health Eating Disorders Program for 2 years and the internationally renowned Community Outreach Partnership Program for Vancouver’s St. Paul’s Hospital Eating Disorders Program for 4 years and private practice throughout this time.

Jessica has training in cognitive behaviour therapy, dialectical behaviour therapy and family-based therapy or the Maudsley Model for the treatment of eating disorders.  Her work with those that struggle with anorexia, bulimia and binge-eating has been helpful in developing unique strategies to make changes in eating as comfortable as possible for all of her clients.

Using similar principles for change, she has also helped individuals and entire workplaces, through workplace wellness programming, to optimize general health.  She has helped her clients manage weight, chronic diseases such as diabetes and heart disease, prepare others for pregnancy, get on the cutting edge on their athletic performance, or discover ways to cope with IBS.

Jessica holds degrees in Biology from Simon Fraser University and Food and Nutrition from Ryerson University in Toronto.  She is currently working on her Masters in Counselling Psychology at the University of Calgary and looks forward to using these skills to further help her clients improve their relationship with food.

She is a member of the College of Dietitians of Alberta and Dietitians of Canada.  She has co-authored a manual for the self-management of chronic disease and was featured in newspapers and magazines such as Chatelaine, Flare and Elle and David Suzuki’s Blog.

Lindsay Gervais, Registered Dietitian, strives to help clients to develop a healthy relationship with food, and move away from the “good food” vs. “bad food” mentality.  She believes that fueling the body does not always require elaborate recipes. She is passionate about creating simple, low-cost recipes that are easy for those that work long hours, have busy families, or anyone who feels unfamiliar with cooking.

Lindsay has experience in nutrition counseling for Eating Disorders, Cystic Fibrosis, Crohn’s Disease, Ulcerative Colitis, Irritable Bowel Syndrome, Eosinophilic Esophagitis, and Celiac Disease. She has worked with a combination of pediatric and adult clients.

Lindsay is a member of the College of Dietitians of Alberta and holds a degree in Nutrition and Food Science from the University of Alberta.  She provides evidence-based recommendations, and has experience in nutrition research. She is a primary co-author of a research project titled “Adherence to a Nurse-Driven Feeding Protocol in a Pediatric Intensive Care Unit,” which was based out of the Stollery Children’s Hospital in Edmonton, Alberta. The manuscript was published in the Journal of Parenteral and Enteral Nutrition in February 2017. She had the opportunity to present their research poster at ASPEN’s Clinical Nutrition Week Conference in 2017, which was awarded “International Abstract of Distinction” in the area of pediatrics.

In her free time, Lindsay enjoys spending time with close friends and family. She can be found snowboarding, lifting weights, hiking, and floating down the Bow River. She loves to travel and experience different food, customs, and cultures. Her most recent trip was 5 weeks of backpacking in Nicaragua, where she ate plantains, papaya, and “gallo pinto” (rice and beans) on a daily basis.
