The Dietary Intervention to Enhance Tracking with Mobile Devices (DIET Mobile) Study: A 6‐Month Randomized Weight Loss Trial

Objective To examine the use of two different mobile dietary self‐monitoring methods for weight loss. Methods Adults with overweight (n = 81; mean BMI 34.7 ± 5.6 kg/m2) were randomized to self‐monitor their diet with a mobile app (App, n = 42) or wearable Bite Counter device (Bite, n = 39). Both gro...

Summary:Objective To examine the use of two different mobile dietary self‐monitoring methods for weight loss. Methods Adults with overweight (n = 81; mean BMI 34.7 ± 5.6 kg/m2) were randomized to self‐monitor their diet with a mobile app (App, n = 42) or wearable Bite Counter device (Bite, n = 39). Both groups received the same behavioral weight loss information via twice‐weekly podcasts. Weight, physical activity (International Physical Activity Questionnaire), and energy intake (two dietary recalls) were assessed at 0, 3, and 6 months. Results At 6 months, 75% of participants completed the trial. The App group lost significantly more weight (−6.8 ± 0.8 kg) than the Bite group (−3.0 ± 0.8 kg; group × time interaction: P
