Objectives: Greater dietary self-monitoring adherence is associated with weight loss, however, the dietary self-monitoring adherence criteria that predict weight loss are unknown. The criteria used to define adherence to dietary self-monitoring in obesity treatment tend to vary, particularly in studies that include dietary self-monitoring via mobile applications (apps). The objectives of this study were to (a) determine weight change outcomes related to app-based dietary self-monitoring and (b) determine the associations between the frequency, consistency, and completeness of dietary self-monitoring and weight change. Methods: In this single-arm uncontrolled prospective study, employees at a large, urban health system who had overweight or obesity self-monitored dietary intake for 8Â weeks using the Calorie Counter by FatSecret app. A paired sample t-test examined the association of app-based dietary self-monitoring and weight change; linear regression examined the associations of frequent, consistent, and complete dietary self-monitoring and weight change. Results: A significant mean difference [t (89)Â =Â 6.59, pÂ <Â 0.001] was found between baseline and 8-week weight (MÂ =Â âˆ’1.5Â Â±Â 2.1Â kg) in the sample (NÂ =Â 90). Linear regression revealed a significant association [F (1, 88)Â =Â 7.18, pÂ =Â 0.009] between total weeks of consistent dietary self-monitoring (MÂ =Â 4.4Â Â±Â 2.8) and percent weight loss (MÂ =Â âˆ’1.54%Â Â±Â 2.26%), and a significant association [F (1, 88)Â =Â 6.42, pÂ =Â 0.013] between dietary self-monitoring frequency (MÂ =Â 50.1%Â Â±Â 33.3%) and percent weight loss. The total weeks of complete dietary self-monitoring (MÂ =Â 3.42Â Â±Â 2.87) was not associated [F (1, 88)Â =Â 3.57, pÂ =Â 0.062] with percent weight loss. Conclusions: Consistent and frequent app-based dietary self-monitoring were associated with short-term weight loss. Emphasizing these aspects of self-monitoring may be an avenue for decreasing the burden of self-monitoring.
