Background Long COVID (LC) is a chronic multisystemic condition which substantiallyimpact the quality of life. Despite the staggering burden of LC, there is still noeffective treatment.Because fasting promotes anti-inflammatory and antioxidant responses, which are involvedin the pathophysiology of LC, we hypothesized that it might improve daily functioning andhealth-related quality of life in patients with LC.The aim of this single center, one arm, prospective pilot clinical trial will be toassess the feasibility and acceptability of prolonged fasting for LC. The main questionsaims to answers are; 1. Does in-home prolonged fasting (7 days) is feasible and acceptable for patients with LC 2. Is there a clinical benefit associated with fasting is LC patientsParticipants (adults 18 year and older) will be asked to 1. Fast for 7 days 2. Have in-person visit at baseline (day 0) and at day 9 for checkups and tests 3. Answer difference questionnnaires about their perceived health during and after fasting
