The goal of this clinical trial is to learn about the effect of time-restricted eating (TRE) to 10 hours per day on the regulation of appetite, the desire to eat, and the quality and duration of nocturnal sleep in adults with normal weight and short sleep duration and/or habitual poor quality sleep. The main questions it aims to answer are: 1) How does a time-restricted eating protocol affect appetite and desire to eat? and 2) How does a time-restricted eating protocol affect nighttime sleep duration and quality? Participants will be asked to follow a TRE protocol on which they must restrict their eating to a self-selected time window of 10 hours per day (but with mandatory fasting from 11 p.m. to 6 a.m.) for 2 months. Researchers will compare the intervention with a control group, in which the participants should follow their usual diet without any time restriction, to see if the intervention decreases appetite and desire to eat, improves the quality, and increases sleep duration.
