The study's aim is to determine if nutrigenomics-based dietary advice is a greater motivator for dietary change amongst an athlete population. Specifically, the investigators will be examining whether nutrigenomics-based personalized dietary advice results in greater changes in dietary intake and body composition amongst athletes compared to personalised population-based sports nutrition advice. It is hypothesized that the Nutrigenomics in Sports Nutrition group would engage in greater dietary changes and better adhere to the dietary advice compared to the standard advice group.
