Description
Summary:Summary Objective Evaluate the effects of an online commercial weight management program, with and without provision of a ‘smart’ scale with instructions to weigh daily and weekly tailored feedback, on weight loss and the frequency of body‐weight self‐monitoring. Methods Participants (N = 92; body mass index 27–40 kg/m2) were randomized to 6 months of no‐cost access to the Weight Watchers Online (WWO) platform alone, or enhanced with a cellular‐connected ‘smart’ scale, instructions to weigh daily and weekly pre‐scripted email feedback (Weight Watchers Online Enhanced [WWO‐E]). The number of days that weight was self‐monitored (via ‘smart’ scale in WWO‐E and manually in WWO) was recorded automatically across the 6‐month trial. Objective weight was measured at baseline, 3 and 6 months. Results While both groups achieved statistically significant weight loss, mean ± standard error weight loss did not differ between WWO‐E and WWO at 3 months (5.1 ± 0.6 kg vs. 4.0 ± 0.7 kg, respectively; p = 0.257) or 6 months (5.3 ± 0.6 kg vs. 3.9 ± 0.7 kg, respectively; p = 0.116). However, a greater proportion of WWO‐E lost ≥5% of initial body weight at 3 months (52.2% vs. 28.3%; p = 0.033), but not 6 months (43.5% vs. 30.4%; p = 0.280), compared with WWO. Mean ± standard deviation days with self‐monitored weight was higher in WWO‐E (80.5 ± 5.6; 44.7% of days) than WWO (12.0 ± 1.0; 6.7% of days; p
