Fasting & Programming

Normally my brain is thinking 10 different things at one time. It is fairly difficult for me to focus (more so since I work at an office that has 5 TVs that I can see, and a couple of channels I can hear). The first few days of fasting, I was surprised how easily I was able to focus. Frankly I was far more productive than I normally am. Unfortunately, I've since reverted to the natural state of affairs -- I can no longer tune out TVs, youtube clips, etc.

In previous years, the first few days would actually be extremely difficult. I now realize that I was getting what is often called the "carb flu." This year, before Ramadan, I was on a low carb diet (Tim Ferriss' Slow Carb). Perhaps because of that, my body was already used to fewer carbs.

Hunger is not debilitating and if I could have water, I could probably 'fast' for 48 hours pretty easily (such fasting is actually recommended by the likes of "East Stop Eat" author Brad Pilon).

Can we apply this to sleeping too?

Usually this occurs when I am in the midst of something that requires a good bit of effort such as tackling a thorny algorithmic conundrum or analyzing a particularly complex call stack. If I attune my mind to repress the pangs of bodily need I occasionally feel as if the external world melts away and I slip into an almost mystical state of oneness with the task at hand. Needless to say, I have been surprised immensely by this development.

One theory I have is that the blood flow that would normally be assigned by my body to the act of digestion is now free'd up to be reallocated to the ole cranium. Plausible? Unsure, but am certainly enjoying these life experiments!

Side note: for those observing the fast I have also noticed that my immune system is closely linked with the gut and my self-imposed starvations can lead to immune system compromise. Make sure you supplement your Iftar goodies with some replenishing nutrients such as pro-biotic yogurt smoothies rich in vitamin C and home-cooked chicken consomme.

There are a lot of things you can do to prepare for a fast. For example, cut back on caffeine, sugar and even salt in the days or weeks ahead of your fast. Also, gorging on food the morning of a fast is not really healthy and is a sure recipe for "Ramadan code."

There was a fantastic article on fasting in Harper's Magazine this past March that covers the history of fasting, "Starving your way to vigor: The benefits of an empty stomach." Sadly, you have to be a subscriber to read it online:

Fasting doesn't have to devastate your mental faculties. I actually find that it helps me focus, and I have started doing it a few times a year.
