Fasting through Finals

This week is final exam week at Kyungsung. I will be listening to about six hours of conversation between freshmen students of English as a Foreign Language, and I have at least two and a half hours of one-on-one interviews scheduled with my Building Relationships in English students. It's not bad compared to last semester, when I had about 16 hours of conversation to listen to, and didn't even try to do the one-on-one interviews.

Yesterday (Monday) was the final meeting of the year for the Busan Doctors' Band, of which I am a non-doctor member. They treated us to a huge sushi and pizza (not sushi-pizza) dinner. An odd combination, but one which they have embraced for some years. The restaurant where we eat has come to expect it, and doesn't seem to mind. After all, they have a room full of eating, drinking customers (there must have been two dozen of us) on a Monday evening. 

I ate a lot, but not a crazy amount. I had only eaten a pair of boiled eggs for lunch that day, and no breakfast. I was hungry, but mostly in anticipation of a great meal. I had also decided that for this week of final exams, the Doctors' Band Feast would be my last meal until Friday evening (though now I am thinking Saturday lunch). I am doing it partly for my health, and partly to boost me through this week. 

I know that today will be a little rough, especially at dinner time, but I am absolutely sure that I can do it. I've already made the decision, now it's just a follow-through of basically NOT eating. This will be my second 5-day Fast (assuming I last until Saturday dinner), so I have some idea of what to expect: today should be the worst of the hunger. It's not bad now, but tonight I'll hit the 24-hour mark and feel it the strongest. Tomorrow won't be as bad, and Thursday the hunger will be background noise, like the heater kicking on in January. "Oh yeah, I'm hungry. What's next on the to-do list?" On the physical side, this one will probably drop me under 100 kg, which is less than I have weighed since before I got married (in 2001!). It's exciting to think that I may get there this week, before 2024 is finished! At the end, I will (try to) ease back into eating gracefully. The book (next paragraph) suggested a small snack an hour before taking on an actual meal. We shall see. It does not pay off to think too much about which food I will eat this early in the game. Just makes me hungry. Because once again, hunger is more about the brain than the stomach.

I just finished the book Complete Guide to Fasting: Heal Your Body Through Intermittent, Alternate-Day, and Extended Fasting by Jimmy Moore and Jason Fung. My clinic recommended it, and I can hear a lot of their advice echoing from this book.

One of my main takeaways is that obesity is a modern disease, as is Type 2 Diabetes, which I had been queued up to take part in. They are a result of a huge environmental change: for most of history (and prehistory) people (and other animals) went through cycles of feasting and fasting. When you make a big kill, or find a huge honeycomb, or a tree full of ripe fruit, it makes sense to pig out in order to lay up fat stores for the winter, or the desert, or the long voyage. The local prey migrates. A hoard of locusts strips the landscape. Drought wipes out the local vegetation. Winter arrives in Canada. Maybe it's only a day or two, maybe longer. But a fast was always around the next corner, if not the one after that. Fasting was a regular part of life, and we are designed for it.

We (modern humans) understand this about exercise. We know (whether or not we act on it) that exercise is good for our health, even though we don't need to be able to run away from a tiger or climb a tree when the jackals come or swim out of the water before the shark gets you. We know that without exercise, the body falls into disrepair, the brain doesn't work as it should, and the emotions get messy. So we (hopefully) make time to walk, or go to the gym, or do yoga or whatever. At the very least, we have been taught that it's a good idea to do so.

But we act as though fasting were dangerous. We have built an environment in which we expose ourselves to feasts daily, but treat fasting as an evil. Three meals a day, never skipping. Snacks in between. Do we need that much food? Certainly not for nutrition or energy. Not unless you are training for a marathon or the Olympics. But eating feels good, right? Eating is comforting. Eating relieves stress. God knows it is for me. 

Some people have adapted to this environment better than others, for sure. But in general, humans don't deal well with feasts being available 24/7. I can find a convenience store or restaurant or grocery store at any time of day, and I have access to refrigerators and cabinets stocked with food that would have blown my ancestors away, as recently as a hundred years ago. Sure, there have always been people at the top with ready access to food, but they were the minority. We have all become that minority.

I believe that this is a hugely important lesson in general health, and that it will have at least the same impact as deliberate exercise has had on society. Maybe more. But it has one disadvantage over the exercise insight: it's hard to make money off of fasting. Sure, I paid $9 for a book about it, and I pay/have paid my clinic for their consultation and monitoring. But I don't need to buy special clothes for fasting. (Smaller clothes at some point, for sure. I'm ready to abandon some of my shirts, and have already left behind some pants.) I don't need to go to a special place for fasting. I don't need to do any special shopping: I buy a little more coffee than usual, and drink hot salt water. It really cuts back on my food budget when I fast, and I don't come anywhere near making up for it when I go back to eating. In fact, my appetite in general is lower.

So no one can make much money off of this (yeah, I bought the book for $10, but I'm not going to buy it again), and the companies who sell me food would lose money. That is where we will see (and have seen) push-back: Big Food doesn't want us to buy less, they want us to buy more. Big Pharma makes money hand over fist selling insulin. Do they want you to know that fasting is an effective way to CURE diabetes? Hell no! (By the way, if you are taking insulin or other medicine for diabetes, don't try fasting without consulting your doctor! There are some potential problems on that journey and you should not take medical advice from a guy with a blog!)

Here's a whole aside paragraph for pre-diabetic people: if you fast for 24 hours (no food between dinner one day and the next) your blood sugar will not drop significantly, because your liver stores up sugars for between meals. However, your pancreas will get a mini-vacation from producing insulin. That break can be the beginning of getting back to a healthy normal. Can you go for 24 hours with no food? Yes. Will you be hungry? Yes. But like any discomfort, you will get more comfortable with it. I am learning to be comfortable with hunger after a lifetime of not tolerating it any longer than necessary. And it is doing me good.

If fasting catches on, the push-back from industry will get more intense. Especially if you live in a country where the people making the most money have the biggest say in the laws of the land. (Which, to the best of my knowledge is every country. Though some take their citizens' health more seriously than others.)

I have more to say about this. My intention was to write about a spiritual aspect of fasting, but I got distracted, so I'll leave you with this:

Drinking only coffee today, with no food, I have gotten a stack of grading done, administered some final exams, updated some lessons, and written a blog post. And it's only 1:00 p.m. This is not the old, eat-when-I'm-hungry me! I feel like Super-Rob! I know that if I eat a snack it will wake up my digestive system, which will demand a meal. If I give in and have lunch (or dinner), it will leave me sluggish and ready to be entertained. Best case scenario I read a book. Worst case, Netflix or YouTube for a couple of hours, then drag through a tiny bit of work, then head home.

On the other hand, if I continue this fast I will wake up sharp tomorrow. I won't need as much bathroom time, I will be more cheerful, focused, and awesome. I might finish my grades in record time and start the planning I need to do for next semester. I never, ever thought I would say this, but I enjoy fasting, and it is clearly benefiting me!

I have other things to write about, such as being Santa Claus. But that will have to wait for another time.
