I have read about bread and water fasts many monastics and lay people do on Wednesdays and Fridays. How is this fast carried out exactly? Does one eat a slice a bread for each meal of the day? Or is bread eaten only once?
I think throughout the day, bread and water are taken (thrice, water also on other times). I must advise you however, to eat some vitamin pills if you do this fast. Bread does not contain all you need. We must take care of our body too.
