OBJECTIVES: This study aimed to evaluate the effects of an 8-h Time-Restricted Eating (TRE) intervention over 12 weeks on weight loss, body composition, and sleep in adults with Obstructive Sleep Apnea (OSA). METHODS: A randomized crossover clinical trial was conducted. Participants aged 30-65 years with a Body Mass Index (BMI) ≥30 kg/m2, diagnosed with OSA, of both sexes, with eating windows from 11 to 14 h were included. The participants were randomized into an 8-h TRE intervention (meals between 11 AM and 7 p.m.) or control group (eating window >10 h and nutritional guidance). Twelve participants completed the intervention. Measurements included body weight, height, waist and neck circumference, and body composition (bioelectrical impedance). Sleep parameters were assessed using a Biologix® portable sleep monitor and questionnaires. RESULTS: The average age of the sample was 44.6 ± 7.84 years, 50% female. Adherence to the TRE intervention was 4.2 days per week. No significant effects of TRE were observed on body weight or anthropometric outcomes, body composition, or sleep parameters. CONCLUSION: The findings of this study suggest that a 12-week 8-h time-restricted eating intervention was not associated with reductions in body mass or body composition and sleep parameters evaluated by a portable monitoring device.
