I'm sorry, I think I was unclear; I totally agree with you that the benefits of fasting are well documented and extensively studied. In addition to conveying possible mental benefit, the fasting is an attempt on my part to feel hunger again. I recognize that probably does not come off well, but I'm never hungry. It's been years. I don't eat all the time, I just eat when I feel like it. I remember times when I was actually hungry, and while life is easier now, I think it might be useful to go find that hunger again.
100%. This was the mind blowing realization the first time I fasted for a good 24+ hours. Feeling ACTUAL hunger, and realizing that what I normally associated as hunger was either thirst or restlessness.
