I once fasted for about a week while suffering an illness that wouldn't let me keep any food down. I only drank water during that time. To my surprise, after several days of not eating, my hunger disappeared completely. It was scary, but also eye-opening. The experience taught me that hunger is not the "you require food right now in order to survive" signal that everyone thinks it is.

There's an idea out there, no idea how true, that what most first-worlders call hunger isn't even really hunger. More like withdrawal symptoms from food addiction. The hunger that comes back when you're really malnourished is much more painful/compelling. Or so I've heard.

Same here. It disappeared after the first 24 hours for me and I didn't feel any hunger for the next 2 days, which was really weird. I didn't feel any tiredness or cognitive impairment (this is difficult to prove though, lol) either.

What a coincidence! Today is my 5th day of fasting. I've only been having water and coconut water[0] (one or two glasses a day).

The first few days which were a little tough. From midway through the third day onwards, I started feeling absolutely fine. There is an overall feeling of lightness. And, of course, the amazing experience when I have that glass of coconut water is truly indescribable!

Lots of people I speak to seem scared of accidentally loosing too much weight and starving to death...

I don't really understand it though... Between 'too heavy' and 'too light' exists 'just right', and it's pretty hard to miss...

Like the people that are afraid to lift weights because they might get "too bulky."

The human mind is bizarre.
