Fasting is great and all if you don't have to perform mental tasks throughout the day. When I am on vacation and have time off of work to just relax, I regularly forget to eat, and I barely even notice. When I'm at work and doing programming, however, even the slightest reduction in my caloric intake schedule results in me feeling lightheaded and "foggy". My ability to code effectively plummets, and I also find myself unintentionally being more irritable towards co-workers. As such, my job as a professional programmer basically requires me to eat regularly. Fasting is not an option for me, unfortunately.
