Found this interesting information giving confirmation to ancient practice of fasting.
Fasting and health benefits – Scientific confirmation
Yoshinori Ohsumi, the 2016 Nobel prize winner for Medicine for research into autophagy titled his Nobel Lecture “Autophagy (self-eating)— An Intracellular Recycling System”
Throughout the recorded history of mankind, fasting has been a stalwart of traditional health and healing practices. This is true for virtually all regions of the earth and virtually all religions of the world. The roots of this ancient healing tradition may lie in the the sub-cellular cleansing process of autophagy, which is only just now being unravelled by science. Autophagy is one of the most evolutionarily conserved pathways known to exist, and can be seen in almost all multi-cellular organisms and many single celled organisms. Autophagy refers to the body’s response to a lack of food (fasting) which stimulates a degradation pathway of sub cellular components.”
“Of course, if your body has more protein than necessary, then it may certainly excrete the excess amino acids or convert it to energy. While most people think growth is always good, the truth is that, in adults, growth is almost always bad. Cancer is too much growth. Alzheimer’s disease is the accumulation of too much junk protein (neurofibrillary tangles) in the brain. Heart attacks and strokes are caused by atheromatous plaques. These are excess accumulation of many things, but prominently, smooth muscle cells, connective tissues and degenerative materials. Yes. Too much growth of smooth muscle is instrumental in causing atherosclerosis that causes heart attacks. Polycystic diseases like kidneys and ovaries are too much growth. Obesity is too much growth.”
