Study to Evaluate the 'eNutri' Online Personalised Nutrition App in the United Kingdom (UK)

Proof-of-principle Pilot Study to Investigate Whether Online Personalised Dietary Advice Given by the eNutri Diet App Encourages Greater Dietary Behaviour Change Than General Advice in UK Adults After 12 Weeks

The proof-of-principle EatWellEUR pilot study will investigate whether online personalised dietary advice encourages greater dietary behaviour change after 12 weeks compared with general population-based diet advice. Dietary change will be quantified from an 11-item diet quality score (DQS) suitable for Northern European populations that is calculated from the results of the eNutri food frequency questionnaire (FFQ) at baseline and week 12.

The proof-of-principle EatWellEUR pilot study will investigate whether online personalised dietary advice encourages greater dietary behaviour change after 12 weeks compared with general population-based diet advice. Both groups will receive two prompts to remind them of their diet advice at weeks 4 and 8. Dietary change will be quantified from an 11-item diet quality score (DQS) suitable for Northern European populations that is calculated from the results of the eNutri food frequency questionnaire (FFQ) at baseline and week 12. 98 participants will be recruited per study arm and will be randomly allocated to an intervention arm using a minimisation technique integrated with the eNutri app.
