The main questions aim to answer: Whether intermittent fasting would allow participants to experience an improvement in their sleep quality, duration and latency? Whether intermittent fasting would ameliorate participants' quality of life and reduce chronic fatigue symptoms? Researchers will compare the two most prevailing fasting windows of intermittent diet including an early morning feeding window (8 a.m.-4 p.m.) and a late feeding window (12 p.m.-8 p.m.) to see if there is a difference among these feeding windows on sleep and quality of life. Participants will: * Be divided into two groups (group A and group B) that will alternate their fasting windows. * Group A will start with intermittent fasting over a feeding period from 12 p.m. to 8 p.m. for one month, then a two weeks period of usual eating habits (washout period) and finally one month of intermittent fasting with a feeding period from 8 a.m. to 4 p.m. * Group B will follow intermittent fasting over a feeding period from 8 a.m. to 4 p.m for one month, then a two weeks period of usual eating habits (washout period) and finally one month of intermittent fasting with a feeding period from 12 p.m. to 8 p.m. * At enrollment, at the end of each month of intermittent fasting and at the end of washout period participants will be asked to complete some questionnaires and wil…
