Once a year, I am fasting for 24 hours. No food or drink at all for whole 24 hours.
Recently I thought about what is happening to me during those 24 hours, and realized there might be something strange going on. I will try to describe the things I find strange:
- I do not feel thirst or hunger at all. Not even after 20 hours.
- I still urinate after 10, 15, and 20 hours, and unlike what I would expect from not drinking, the color is not very dark. (actually, same as when I drink normally)
- I can still perform energy consuming tasks after 20 hours without eating or drinking anything. I'm not talking about running in the park or lifting weights, but I can walk, do house chores etc, and only after 20 hours or so the body starts to "protest" in the form of headache.
All of the above led me to think that maybe when knowing it's going to be deprived of energy, the body enters "Power Save" mode, allowing it to function as usual under those conditions? (to a limit of course, but still - I would expect hunger, thirst, and headaches to appear few hours into fasting)
