48 hours is about the most that I have done. Even at 24 hours you begin to recognize how much of modern life revolves around eating. Trying taking a stroll through the city while fasting. Within 10 seconds you see people eating icecream, candy bars, cokes, a zillion restaurants, convenience stores, not to mention alcohol. With fasting I found I had low energy and would be really, really bored. There was a lot of temptation to fill time with just munching on something. I also found that when I broke my fast, I didn't eat as much as I expected to. No huge pigout meal or anything. I am not religious, but I think Ramadan is an example of a really healthy religious practice because it reminds people of their relation to food.
