Hi. I'm new to this forum and I've been fasting for three days. So far, my tongue is coated and otherwise, I am not hungry and I'm not tired. I have fasted before and during my first fast, whenever I was excerising I seemed to get more and more weak. I usually did brisk walking for about a hour a day.
I'm wondering, in order to not feel extremely weak and have severe headaches should I completely quit excerising or just cut back the time and distance of my walks?
Sorry if this is a question that is frequently asked.
