Wake and late5/6/2023 ![]() ![]() recently reported that a TRE intervention in which individuals self-selected their 8 h eating windows resulted in weight loss ( 2). In a randomized control trial, Chow et al. Several studies have shown that restricting adults with long habitual eating windows (15 or more hours per day) to a food intake window of 8–10 hours per day results in weight loss ( 1– 3). Time-restricted eating (TRE), limiting eating to a specific daily window, is emerging as a novel weight management intervention. 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.Ĭonclusion: A self-selected TRE intervention significantly shifted meal timing, reduced late-night eating while prolonging sleep duration. 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, p = 0.03). The non-TRE group, on average, maintained their eating pattern. 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). Results: At 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). Data are presented as mean ± standard deviation. Independent samples t-tests compared differences between groups. Anthropometrics, HbA1c, an oral glucose tolerance test, and 2 weeks of actigraphy monitoring were completed at pre-intervention and end-intervention. All participants logged oral intake using the m圜ircadian Clock mobile application throughout the entire intervention. 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. Methods: Twenty participants 18–65 years with BMI ≥25 kg/m2 completed the 12-week trial. 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. ![]() 5Division of Diabetes, Endocrinology, and Metabolism, University of Minnesota, Minneapolis, MN, United Statesīackground: Time 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.4Department of Biochemistry, Molecular Biology and Biophysics, University of Minnesota, Minneapolis, MN, United States.3Salk Institute for Biological Studies, La Jolla, CA, United States. ![]() 2Department of Medicine, University of Colorado Anschutz Medical Campus, Aurora, CO, United States.1Department of Pediatrics, University of Colorado Anschutz Medical Campus, Aurora, CO, United States.Manoogian 3, Satchidananda Panda 3, Douglas G.
