 Abstract: Background: Awareness of the importance of healthy diets for mitigating climate impact is increasing, but it is still difficult for consumers to act in accordance with this. Smartphones enable new communicative approaches for nutrition and climate behaviour change, and can further be integrated into dietary assessment methods, reducing their complexity and time-burden for trial participants in free-living contexts. Aims: To investigate which challenges are associated with the collection of good quality data through the remote digital photography method in out-of-the-home settings. And to evaluate how the FoodPal smartphone application can help consumers choose meals that have a more positive nutritional and climate impact. Methods: A quantitative controlled trial featuring the remote food photography method was used to measure food choices, and compliance registers were taken for an evaluation of the methods' challenges. A web-based questionnaire and qualitative interviews were used to evaluate the barriers and limitations associated with the use of this method and of the FoodPal app, and to further uncover which application facilities consumers demand from this type of app. Results: Canteen collaborators complied with data results and practical aspects for the conduction of the trial, but trial participants did not comply with enough photographs for a valid statistical assessment of the effects of the use of the FoodPal app prototype on the participants' nutrition behaviour. The main challenge associated with the remote digital photography method is that participants forget to take photographs. The FoodPal app prototype's main limitation was associated with the provision of generic information and the lack of interaction with the app. Application facilities for a revised FoodPal app are to include both health elements and aspects related to concerns regarding the production of foods, and consumers demand personalization of the profiles obtained with the app. Discussion: The main barriers for participant compliance are associated with lack of both extrinsic and intrinsic motivation. An increase in the personalization of reminders for compliance, plus the creation of a stronger sense of connection and responsibility towards the project, both through extrinsic and intrinsic motivational factors, should be considered when designing future trials that make use of the remote digital photography method. A revised version of FoodPal should give its users the possibility of interacting and personalizing its content, self-monitoring their choices in relation to established personal goals, and provide them action oriented feedback for effective behaviour changes.Conclusion: The remote digital photography method is easy to use and provides good quality data, making it an ideal method for dietary assessment in free-living contexts, as long as trial participants comply with data collection. A revised FoodPal has enormous potential for empowering consumers in making healthier and more climate friendly food choices, but needsfurther development and testing.
