HEAL Award Winner Studying Effectiveness of DNA-based Dietary and Physical Activity Advice

Congratulations to HEAL Graduate Research Associate Justine Horne, RD who received a three-year Canada Graduate Scholarship from the Canadian Institutes of Health Research for her PhD research.

Justine is a PhD candidate in Health & Rehabilitation Sciences under the supervision of Dr. Jason Gilliland and Dr. Janet Madill. Justine’s research seeks to determine the impact of DNA-based dietary and physical activity advice on weight management and body composition, as well as nutrition and physical activity habits, while using the Theory of Planned Behaviour as a methodological framework. To conduct this research, Justine is leading The Nutrigenomics, Overweight/Obesity and Weight Management Trial (The NOW Trial) – a pragmatic, randomized controlled trial in two distinct patient populations.
