I have done it on and off for about two years. You get accustomed to it after a few weeks. Your body adapts and the the glucose curves are nearly identical to normal patterns. Your body activates more fat burning to access reserves, so it helps to burn fat reserves for energy; fat reserves which otherwise are not accessed.
I have been doing three days a week since April and rarely face much fatigue, I commute between 23 km and 36 km each day. I only felt fatigued two weeks ago when I tacked on about another 25 km one evening after a week off. The nice thing is if you have a dinner or lunch to go to on a fast day, you just fast the next day. It is not schedule restricted. The best results have been shown when one skips lunch and dinner (breakfast to breakfast). But I found it more important to eat dinner with the family.
I fasted yesterday and I smashed my
PR on a hill on the way home by about 15 seconds.
