Do a bit of research on it, you would be surprised I know that I was. Not only is fasting safe, there are numerous health benefits to extended fasting. Growth hormone surges after a couple of days to protect muscle tissue from the cortisol spike so muscle loss will be negligible and fat loss is astronomical as long as you don’t work out. That’s the hardest part for me, avoiding the gym and having walking as my only form of exercise. Our body is designed for feast and famine cycles, and fasting is pretty much unarguably better for you than calorie restriction is. It is also infinitely more effective and the health benefits of autophagy are numerous. Not to mention the growth hormone surge from fasting doesn’t go away immediately once you start feeding, meaning that not only is fasting an excellent tool for weight loss, it is actually an incredible tool to increase muscle mass. I promise you that fasting will be incredibly mainstream in the near future.
Dr Jason Fung and Dr Rhonda Patrick are two leading experts on fasting if you want to do further research. Also a simple google search of the word “autophagy” will be incredibly eye opening. Spurfy right here on AM is another very knowledgeable individual on the subject
