I was amazed when I first read about fasting here. My development was strange. In my childhood, I was rather strong and forced myself to fast. Without success. My hunger was always there. Even though I had eaten less, my weight was the same or even increased. At age 36, I had my first major life crisis. Amazingly, I could not eat anything anymore. For days. There was no hunger or desire. My weight started to decrease very quickly. I only ate when the insulin level was in the basement and I got cravings. After that first crisis something changed in my body. There was no more hunger. So I ate nothing for 1-2 days sometimes. My lifestyle also made regular eating impossible. There were no fixed meals, I ate little but spread throughout the day. At some point, I realized that there was a change. Once I had a normal rhythm, on vacation, I could not stand food anymore. My energy was gone. As soon as I ate and fasted again very little, I was able to work without any problems for 12 hours a day. I also noticed that in difficult times, when my head had to think a lot, my weight had also decreased with normal food intake. At some point I read an article that thinking consumes a lot of energy and calories, which I can only confirm. To this day, fasting is part of my life although I do not intend to fast. There is very little appetite. Strangely, I have an incredible amount of energy and have never gotten sick. Whether there is a connection here, I do not know.
