Thank you for your in debt answer, I appreciate the explanation. I will definitely check the Russian site, as well. In fact I checked several abstracts, with the search criteria you suggested, on pubmed as well. Unfortunately none of the ones I read had a definite conclusion on the discussed matter. However, I understand and feel you have better knowledge than I on HCV and how it relates to fasting.
Part of my own info came from the sites emilova.org, http://ru.emilova.eu/
and videos posted there of patients before and after fruit-fasts for chronic conditions, including chronic (C?) hepatitis. Again, I do not pretend to be an expert on the above, and given your opinion, I would not advise from now on, anyone with HCV to undertake long fasts, especially water-only, and especially without proper supervision and viral load tests.
