So, now that I’m exercising again, I’ve had some time to read — while I’m riding the exercise bike, first thing, before lifting or doing resistance exercises. I’ve been combing the Web for material on the benefits of exercise for the brain, and I’m rediscovering a lot of pieces I read a few years back that slipped into the nether regions of my memory. Yes, BDNF (brain-derived neurotrophic factor) is stimulated by exercise. And intermittent fasting can be good for your brain.
I have an easy day today — I’m telecommuting, and my afternoon appointment will probably be cancelled — so I don’t have a lot of energy demands on me, and I can safely get through the day without being in danger from hypoglycemia or not having enough energy to get by. When I’m commuting and I’m on my regular schedule, I need to have all pistons firing, which means I need a steady flow of energy to my brain, so fasting is not possible.
Today, though, I’m good to fast. I’ll drink my water and tea, get some intermittent exercise, and probably take a nap later this afternoon. Pace myself, and let my body take a rest from eating. I won’t fast into the evening. I just need to be without food till about 8:00 tonight, which probably won’t be a problem. I usually don’t eat until after 8:00 anyway. I ate my last snack last night around 10:00 p.m., I think — a natural fruit popsicle. So, a 22 hour fast will do the trick.
I learned about intermittent short-term fasting at the blog Getting Stronger, which discusses hormesis, or making your system stronger by introducing small bits of stress that test your system and increase its capacity for performance. I have tried to fast in the past, but it went poorly — probably because I had issues with behavior and emotional regulation, and my diet was pretty crappy, so I was all set up for hypoglycemia that made me a bear. So, I never did much with fasting after a few little tries.
Intermittent short-term fasting, which is where you go without food for about 20 hours, every now and then (some people do it monthly), actually offers a lot of benefits, without the intense stress and strain of prolonged deprivation. I aspire one day to being able to fast longer than 22 hours, but that may actually never be necessary, as reduced calorie intake is also a proven way to help you be healthier.
Anyway, I have been looking for opportunities to fast, but I’ve either been pretty active, or I have completely forgotten (like over the week between Christmas and New Years) that fasting might be a good idea. So, now I am remembering it, and it looks like this is a really good day to do this thing. And I shall.
I know this may prove challenging later today, when I am looking for my lunch around 11:30 a.m. – that’s when I usually eat. And then there is the afternoon snack that I usually have around 2:30 or so… Doing without them, especially when I am working at home with lots of good, healthy food within easy reach, may be a challenge. But I have to keep in mind that I am doing this for a good reason — and it won’t be forever.
I’ll break my fast tonight, and that will be that.
The big challenge today will be keeping my mind on my work and not getting pulled in a bunch of different directions. I’ll spend some extra time today exercising or sitting and breathing, instead of eating. At times when I am usually having snacks or lunch, I will do a little stretching or sit and count my breaths. This could be a really good way to get that extra meditation time I’ve been wanting.
I’ve felt myself jumping quickly into a state of knee-jerk reactiveness, over the past months, and that has not been good. I can’t just snap over every little thing. I need to be more mindful and also better about managing how I behave with regard to my emotions. I know this is an issue for me. So, sitting and breathing and working on my self-restraint while not eating will be a great opportunity for me.
I just need to keep focused and remember why I am inconveniencing myself — and really celebrate at the end, when I get to eat again. It’s only 11 hours and 16 minutes away 😉
