Abstract

Abstract: Objective: This study tested the efficacy of a lower‐burden, simplified dietary self‐monitoring approach compared with a standard calorie monitoring approach for self‐monitoring adherence and weight loss in a mobile‐delivered behavioral weight loss intervention. Methods: Participants ( n = 72) with overweight or obesity who had children 2 to 12 years of age living in the home were randomly assigned to a group that used simplified dietary self‐monitoring of high‐calorie foods (Simplified) or a group that tracked calories (Standard). Both groups received a wireless scale, Fitbit trackers, and a 6‐month intervention delivered via a smartphone application with lessons, text messages, and weekly personalized feedback messages. Results: Percentage weight loss at 6 months was 5.7% (95% CI: −8.3% to −3.2%) in the Standard group and 4.0% (95% CI: −5.7% to −2.3%) in the Simplified group, which was not significantly different. Similar proportions reached 5% weight loss at 6 months (43.2% in Standard and 42.9% in Simplified). There were no differences in number of dietary tracking days or change in average daily caloric intake between groups. Conclusions: Two mobile‐delivered weight loss interventions produced clinically meaningful levels of weight loss at 6 months, with no differences in dietary tracking adherence or dietary intake. The results suggest that simplified monitoring of high‐calorie foods could be a promising alternative to calorie monitoring.
