Hiya'll:
I read a book that promoted fasting for health reasons. Yes giving your system a "day off" gives one a respite from continually creating digestive juices, processing, & all else. The author also points out the practicality of it. We, like all mammals, need to eat. Nutrition is a key life force that needs to be maintained. We all can & usually do, eat more than necessary. This the body stores as fat. When one fasts, the body turns to it's stores & effectively uses the body's incredibility, to focus it's energy on other, more important tasks. If you're a lone animal, depending on hunting, or gathering your own food, an injury may hinder your food access. By not using one's energy for food processing, the body will spend all it's energy on the healing process!
As for "feeling great", this is a known religious practice which allows one to be truly quiet, and bring the body to rest. Gluttony, the opposite of fasting, is a cardinal sin. Not so long ago, & in less developed societies, eating 3 times a day, was not such an easy process. refrigerators & fast foods have made gluttony an societal norm. Once this was only for the prosperous who could afford a continuous food supple, ie: FatCats.
So, despite the AMA's anti fasting propaganda, I personally, found fasting a regularly religious practice, that has brought me into more an overall balance in my life.
