Daily self-weighing within a lifestyle intervention: impact on disordered eating symptoms.

ABSTRACT: To determine whether daily self-weighing (DSW) is associated with disordered eating (DE) symptoms within an adult lifestyle intervention (LI), and to examine changes in DE symptoms during the 18-month trial.One-hundred and seventy-eight adults (53% female, 90% White, 52.0 ± 8.6 years, BMI = 35.0 ± 4.4 kg/m2) were enrolled in a randomized trial testing 2 dietary prescriptions within a LI (standard vs. limited dietary variety). Both arms were taught DSW and had the same contact schedule and calorie and activity goals. Frequency of weighing and DE were assessed at 0, 6, 12, and 18 months. Analyses controlled for treatment arm.At baseline, 16.3% of participants reported weighing ? daily compared with 83.7%, 72.3%, and 68.2% at 6, 12, and 18 months, respectively. There was no relationship between change in frequency of self-weighing and change in DE symptoms at any time point. Further, there were no significant differences between those who weighed ? daily versus < daily on DE composite scores at baseline or 6 months; at 12 and 18 months participants who weighed ? daily reported lower DE scores compared with those who weighed < daily (p = .008 and .043 at 12 and 18 months, respectively). Participants who weighed ? daily achieved better weight losses than those weighing < daily at 12 and 18 months (p = .003 and <.001). There was a significant reduction over time in DE symptoms (p < .0001) and a reduction in odds of meeting criteria for Binge Eating Disorder (BED; ps < .001).Daily self-weighing did not appear to be related to increased disordered eating behavior and was associated with better weight loss outcomes.

Project description:BackgroundTime restricted eating (TRE), limiting eating to a specific daily window, is a novel dietary intervention, but the mechanisms by which TRE results in weight loss remain unclear. The goal of the current study was to examine changes in eating patterns, sleep, and late-night eating, and associations with health outcomes in a secondary analysis of a 12-week self-selected TRE intervention.MethodsTwenty participants 18-65 years with BMI ≥25 kg/m2 completed the 12-week trial. Participants randomized to TRE (n = 11) were instructed to eat during a self-selected 8-h window, while the non-TRE group (n = 9) followed their typical eating habits. All participants logged oral intake using the myCircadian Clock mobile application throughout the entire intervention. Anthropometrics, HbA1c, an oral glucose tolerance test, and 2 weeks of actigraphy monitoring were completed at pre-intervention and end-intervention. Independent samples t-tests compared differences between groups. Data are presented as mean ± standard deviation.ResultsAt preintervention, late night eating was significantly associated with higher fasting glucose (r = 0.59, p = 0.006) and higher HbA1c (r = 0.46, p = 0.016). The TRE group significantly delayed the timing of the first eating occasion by 2.72 ± 1.48 h relative to wake time (p < 0.001) and advanced the timing of the last eating occasion by 1.25 ± 0.8 h relative to bedtime (p < 0.001). The non-TRE group, on average, maintained their eating pattern. Sleep measures did not change from pre- to end-intervention, however greater restriction of the eating window was associated with longer sleep duration at end-intervention (β = -0.46 [95% CI -9.2, -0.4], p = 0.03). The TRE group significantly reduced the prevalence of late night eating (eating within 2 h of bedtime) by 14 ± 6% (p = 0.028) with 63% of participants completely eliminating late night eating at end-intervention.ConclusionA self-selected TRE intervention significantly shifted meal timing, reduced late-night eating while prolonging sleep duration.Trial registryClinicalTrials.gov, identifier: 03129581.
