What about Therese Neumann? She made it a little longer than 2 days without food and water - she lasted until her death, 40 years without food or drink. She just ate one little wafer a day (only if it was blessed). The Nazis didn't get her but they tried.
A medical doctor went to disprove this phony who claimed she ate nothing.
".... In July 1927 a medical doctor and four Franciscan nurses kept a watch on her 24 hours a day for a two-week period. They confirmed that she had consumed nothing except for one consecrated sacred Host a day, and had suffered no ill effects, loss of weight, or dehydration. Montague Summers in the "Physical Phenomenon of Mysticism" speaks of her supernatural ability to survive long periods without food or water. ..1940...Therese refused German ration cards saying she had no need of food or drink."
Silly little peasant women. When they were out sight seeing the country side she would get a good laugh when others needed to stop to get something to eat and drink. The doctor witnessed this Saint himself what was he to do?
And for someone who kicked the food habit, one day she would lose several pounds of blood (wounds of Christ) and by the next she regained her body weight. Over a million people observed her in this bleeding spectacle on most Fridays (not so much during the war years but before and after).
