19 hours :D
When I was extremely sick with a respiratory infection, I didn't eat for about 3 days. And when I did eat after that 3 days, I ate something like a tiny cup of soup, and still wished I hadn't.
i dunno - a couple of days - i used to go a day with almost no food very easily - i credit under-eating with much of my good health
Probably about 40 hours.
2 weeks. Maybe longer
lol like um not a whole day i know that much :s probably not even more than 10 hours.. ive never tried.
till i went blind
if you consider fasting during the month of ramadan,but then again we break our fast at night
