Summary

Background Long COVID (LC) is a chronic multisystemic condition which substantially impact the quality of life. Despite the staggering burden of LC, there is still no effective treatment. Because fasting promotes anti-inflammatory and antioxidant responses, which are involved in the pathophysiology of LC, we hypothesized that it might improve daily functioning and health-related quality of life in patients with LC. The aim of this single center, one arm, prospective pilot clinical trial will be to assess the feasibility and acceptability of prolonged fasting for LC. The main questions aims 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 patients Participants (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
