Fasting for 5 days, running, and meditation

 

I'm trying out fasting again, for the fifth time.  Twice before I fasted for 5 days, and two other times I stopped before that due to problems, probably mostly related to electrolyte balance.

A main point:  why do it?  It was always to experiment with the experience, to see if some of the associated health benefits seem to occur.  Weight loss wasn't necessarily one of those, for me.  I did gain a little weight over the last two years, up from 71 kg to 74, from around 156 pounds to 163, but that seems fine, even though I have bit of a gut.  It's claimed that fasting can improve mental clarity, and initiate autophagy, which can remove some visceral fat, some fat problematically located actually inside or around internal organs, and even potentially lower cancer risk.  Who knows; some research I checked indicates there could be something to a lot of that, but research findings don't seem to confirm most of it.  Of that list you might only notice the mental clarity; I don't think it's possible to change pants size.

To me the main benefits have been serving as a reset for diet habits and improving metabolic flexibility, my body's ability to use fat for energy.  How would I notice that, without fasting, and judging degree of suffering from switching to ketosis?  My energy level when running seems better, more continuous and consistent.  Of course if a meal runs late, or I miss one, then that doesn't seem like a problem, related to acclimation.  

My diet wasn't terrible before but the few fasting trials helped me dial it in to be closer to optimum, very low on sugar and other junk foods, based on very limited between meal snacking, and only moderate sized normal meals.  I eat plenty of fruits and vegetables, limited meat, eggs, and dairy (so I actually supplement protein a little), including diverse rice, grains, some bread, and beans.  I've switched from eating chocolate for a snack to nuts.

The main concern in trying fasting is electrolyte supplementation, which I've addressed in earlier posts.  It's tricky.  It seems like it should be simple, add some salt, potassium, and magnesium, but it's a lot more of those first two salts than you'd expect.

I'll write out how this went, starting writing this post on day 3.

Days 1 and 2:  in the past these were rough times, working through a lot of hunger and loss of energy, and some impact to mental clarity.  For the most part none of that happened.  Even hunger experience was very moderate; it just didn't seem like I was skipping eating most of that time.  

I think if I was hearing of that from someone else I'd be skeptical; two days of not eating was easy, no impact?  It kind of was, especially in comparison with the first three trials.  On the fourth attempt the first day was really easy, but I went out for a speed-work run, a training form relatively new to me, and I think that might have thrown off my electrolyte balance.  Or maybe it was too much for energy conversion from body fat, going beyond what I was adapted to?  Sleep disruption is a normal side effect of fasting, especially if your magnesium level runs low, and I went through that too that time, and then stopped.  

Hunger level, on that fourth trial and for these two days, was like when lunch or dinner runs an hour late; you can feel it, but it's not bad yet.  For someone accustomed to a strict eating schedule maybe an hour late would already be uncomfortable, and it wasn't even that bad.  It was strange.

Energy level and the rest seemed fine too.  I didn't worry about drinking some tisane (herb tea) on the first day to offset the gap from experiencing any food intake, but I did brew some blue pea flowers, chrysanthemum, and stevia the second day, which I drank with potassium and sodium salts added.  

This time I kept drinking a good bit of that salt water, which can be nasty, but didn't use the approach of measuring it out, which I suppose adds a bit of risk, getting it wrong again.  I've had some tea every day, the leftover of some sheng on the first day, shu pu'er on the second (easiest on your stomach, the natural call), and aged white tea today, which worked out.

The oddest part was a lack of impact.  I felt fine on the second evening so I went out to try a short run, just 2 miles, limiting the distance to avoid going through any energy level or electrolyte balance disruption, to see how I felt.  I ran the first two km at an easy 6 1/2 minute pace and set a faster cruise of 6 minutes for the third.  That felt fine, like I could keep it up, or could've pushed faster to run at 5 1/2 min / km speed if I'd wanted, but I had already pushed it too far the last trial, so didn't.  I meditated after that run, but I think I'll cover what that's all about in a separate section.

Day 3:  right away in the morning it really caught up to me, the disrupted, low energy, off feeling.  Not eating for the prior two days definitely didn't lead to an experience of increased mental clarity.  I took the cat to the vet too, running an unpleasant errand, and went via a stupid route for getting it all wrong, missing a couple of turns.  I botch driving here sometimes but not like that.  Waiting at the vet when you haven't eaten isn't much worse than when you have; it's still a bit annoying.  That's even for bringing a laptop so I could check in with work, and catch part of a meeting, before my appointment time interrupted that.

The cat has gingivitis, a mild gum infection.  She's almost 16 so I was worried she might be nearing the end, but after a shot, taking antibiotics in pill form later, and special mouthwash rinse for however long she should be ok.  She scratched the vet because I wasn't holding her legs tightly enough; maybe another focus issue.  It'll probably be my turn to see my own blood tomorrow when I try to rinse her mouth alone.

I'm not sure how the next 2 1/2 days will go.  I hadn't planned to run again right away but if I feel normal later I might try to run for 4 miles, my normal short loop, two routes around the local royal palace.  Muscle and other tissue recovery can be an issue when you don't eat but I didn't feel any soreness from that short 2 mile run.

I'm not fasting mostly for weight loss but it might be nice to lose a few pounds.  I'm up to around 165 pounds / 74 kg now, and I think the earlier fasting might have caused my body to worry about a shortage of food, to go into a winter mode.  That's probably good in the long term related to offsetting rate of aging.  There's a related long story about why I think being a vegetarian for 17 years probably slowed my metabolic rate for a long time.  That low metabolism allows me to run 20 or more miles a week (30 km) and eat relatively little food and still not lose any weight.  Being lighter would make running easier.  As far as aesthetics go it doesn't matter; I look ok, and it would be fine if I didn't.

I feel like I've not really communicated what the nagging symptom of hunger is like, what it really takes to adapt to not eating for days on end.  It becomes normal, to an extent, but you have to internally accept it rather than reject it, or it would definitely be much worse.  Maybe that leads into the part on meditation well enough, and I can put that in the middle of this day by day account.

Meditation:

Again, why do it?  I'm separated from my kids, who are back at school in Honolulu, while I take care of the cats, watch the house, and work locally here in Bangkok.  I can work remotely but someone needs to cover those two tasks, and Eye's mother--their grandmother--is there with them.  She's concerned the months she is separated from them might be some of her last, because she's getting up there in age, but it's also not easy for me to miss some.

my only form of contact with my daughter for now

So I'm making the most of it by meditating, running, and fasting, and holding a tea event here or there (one so far, planning a second).  And some job hunting, but it's hard to log a lot of hours at that activity, so I just keep plugging away at it here and there.

I've settled on meditating for 45 minutes at a time, almost every evening, missing a few sessions if a day ran long or if a run seemed to drain me too much.  It's really hard to describe results.  I might first add that I meditated some as an experiment when I was much younger, seeing interesting results from that, then again 15 years ago when I was ordained as a monk for two months, undergoing limited training at a meditation center.  

Nothing extreme changes as an outcome (usually).  It might give you a bit more mental clarity and focus; that's about it.  I've noticed that I carry tension in my body and experience the background noise in my mind slightly differently than I did early on, 2 1/2 to 3 weeks ago.  My mind seems more settled, and the tension I was holding in my upper shoulders has mostly dissipated.  My lower back tension isn't resolved, and maybe from running my legs tend to hold it too, which may settle out further within a couple more weeks.

Running is also a form of meditation, in a sense.  I have to set my mind to support that exertion level for an extended time, for around an hour for my standard run of 10 km (6+ miles).  Then I sometimes cut that short if heat exposure gets to be a bit much, often when I run at mid-day.  That heat effect feels a little like tiring from running but not exactly like that, more feeling a little off.

As far as the meditation experience itself goes following your breath is a standard practice, to help still your mind, or putting focus in one particular place within your body, maybe your lower stomach, around the diaphragm, or where the breath enters your nose.  Counting can help.  I try to let my mind quiet naturally and only use counting or other focusing techniques when that's not working, although there is always some chatter.  The experience of body tension can be uncomfortable, especially after the half an hour point.  It seems to me that's coming from mental disturbance, as much as retained tension, and that the expectation or desire to stop the meditation is causing it.  

I can settle to be much more comfortable just sitting than 3 weeks ago but I'm far from "there," if there even is such a level.  I set an alarm and it's hard to stop fleeting thoughts from wondering when it will go off, which seem partly triggered by body tension that is uncomfortable.  

Uncomfortable is all relative; maybe it's like the effort and tension from when you walk and carry groceries, and you'd like to put them down, but it's not to the point of a strain like a cramp.  I don't mean 100 yards / meters to a car; in Honolulu we had (/ have) no car so at times we would carry groceries quite far, along with using the bus at other times.  After a km or two the groceries get heavy, even though they're not really heavy, unless you think a couple of gallons of milk plus that much food is.  I could add that my wife switched us to large, sturdy re-usable bags back when that was trendy here a half-dozen years back, saving on plastic use, so it's not as if that looked exactly like someone walking down the street from a grocery store, but it's not that different.  It was odd.

What about meditation plus fasting; how has that changed things?  My patience seems just a little reduced.  If anything my mind might be a little quieter, more calm, but past the half hour point--which I don't track; I'm not watching a clock--there's more "when is this going to end?" feedback.  Physically I might be slightly more relaxed, which could support my theory that my mind's quietude and body tension level are connected.  

Maybe meditation is helping me not experience eating disruption as unpleasant, as it should normally be?  I'm not sure, and at a guess acclimation from prior fasts is more of a cause of that.  My body gets it, that this is one more normal state of being I'll go through.  The same must apply to running or carrying groceries an absurd distance, that after it normalizes one more internal negative feedback loop goes mostly quiet.  I actually like running now, which is strange, since it started as an easy way to exercise in a short period of time instead.  Even running in cross country and track in high school (long ago) I always had mixed feelings about it.

Day 3, later on:  I'm feeling it.  It would've made for a good story to have ran for three days but due to feeling off, tired, and at times very slightly dizzy I shouldn't try.  I've been drinking that nasty sodium and potassium salt water all day but tomorrow I'll measure out what I see as more optimum and parse that out across the day.  Hunger still isn't too bad; odd.  Different foods sound ok, and I feel a bit empty, but I don't spend much time thinking about that.  

Given the way I take these 5 day spans I'll eat at the end of the 5th day, not pushing on for what is really 5 1/2 that next morning, as the clock goes, so I really only have one more full day to go, then most of one.  I don't even stay strict about timing; if I end up fasting for 4 days and 22 hours because dinner timing varies that's fine.  It would be easy to add another half day, and eat the next morning, but it's nice getting the recovery done that extra day earlier, and getting back to normal the next.  

I don't "go big" and eat a lot at the end, and it's really not even possible to, without feeling sick (for me; others who fast say that they can).  Healthy and simple foods taste great at that point; I should probably try breaking the fast with homemade cheeseburgers.  Sort of healthy, I mean.

Day 4, mid-day:  I've really been feeling it all day.  I woke in the night feeling off and re-upped electrolyte intake, then slept well, but it was another rough morning.  I've not had normal energy, clarity, or focus all day.  I think it's not really electrolyte level issues; I measured out the daily salts intake this morning and took a magnesium tablet, plus multivitamin and calcium.  It seems like I'm just not accustomed to ketosis, what people sometimes call "keto flu."  Your body will adjust, but I've probably only been fully in ketosis for the past two days, using the last of what I was digesting or holding as glycogen on both Saturday and Sunday.

Hunger isn't much of an issue; I barely think of food.  That's another thing I didn't mention about meditation, that food might cross my mind, but no more so than what shows I've been watching, one more minor part of mental background noise.

I drank a mild black tea today and that was fine, no problem.  Shu pu'er is most sensible, easiest on the stomach, but just avoiding green tea, sheng pu'er, or very low oxidation level oolong is enough.

I expect that I'll feel a little better tomorrow.  I'd like to try running again this evening, to see if I can push it for forcing my body to convert fat energy.  It would be a stretch though.  I could essentially just crash for the next 12 hours or so afterwards, but I don't know what that fallout would be like.  Other somewhat scary symptoms go with the territory for fasting and electrolyte imbalance:  irregular heartbeat, dizziness, problems sleeping.  Walking for half an hour would be playing it safe but that's a tough call as a runner.  Not very many runners ever sort out if they can keep running after 4 days off food though.

Day 4, after a run:  I felt "keto flu" symptoms all day, only recovering after a nap after work.  Then I felt ok, so I went out for a run.  No matter how that went I planned to keep it short, because I just spent two days feeling quite off.  It went well, it felt normal, and slipped back into a normal 6 mile per km pace for the last 1 1/2.  I probably feel as good as I've felt over this fast now.  I experienced a little leg cramping during a stretch, a sign my electrolyte balance might not be right, so I came back and drank another cup of salt water and took a magnesium capsule (adding up to double the daily requirement; I guess that's fine).

I think if I fast again within the next month or so I could probably do those 2 mile runs daily, for being better acclimated, or even bump it up to 4 miles for a couple, at a slow pace.  Better safe than sorry this time; it's as well to not rush fasting experiences, as I've learned from a couple of failures.

Day 5, morning:  I was up in the night again, drinking more salt water at 5 or so.  I did drink shu pu'er this morning.  I feel much better than the last two days but still not normal, still disrupted.  It all makes me question if it's a good thing to even try this.  I won't know if most of the supposed benefits occur (more mental clarity, later on, autophagy, visceral fat reduction), and I don't expect to lose weight.  My diet was as good as it's likely to ever be, so that reset function doesn't apply.  I feel relatively ok today, not so tired and slightly out of it, but perhaps still not completely normal.

On the other side I think it all would normalize, if someone kept it up, I guess if they were pursuing weight loss (the main reason), or were really convinced of those benefits.  In the Reddit fasting sub people discuss applying radical rotating fasting approaches, rolling 48s or 72s, not eating half the time on either a 2 day or 3 day cycle (or 4 or 6 counting both parts).  One person recently commented they ate only 2 days a week, so with 5 days off, for an extended time.  Those people often mention body weights and loss amounts that related to more extreme circumstances.  

Even someone really wanting to lose only an extra 20 pounds of fat may use fasting.  One guy commenting in the Reddit fasting sub was at optimal body weight but was very low in muscle tissue, with a high percentage body fat, and he was asking if fasting and working out would help him.  My guess is that eating a moderated caloric input but healthy diet while working out would be better under those circumstances.

Day 5, at about the end:  towards the end it's natural to keep thinking that ending an extra hour early would be fine.  I went to the grocery store during lunch, since there's no food here, and being around food wasn't a problem.  I felt a little off earlier and drank the last of the saltwater mix I had made up and I'm fine.  Energy level and clarity have been close to normal today.

I only drank a tisane that once; I didn't miss eating enough to try to replicate it.  My throat felt odd so I drank the juice of a small lime on the last day.  Google says that I might have ingested 20 calories doing that.  There must be people out there who would see that as not really true fasting.

Related to the meditation again I keep thinking why am I really doing this.  I'm not that far in the hole related to mental clarity and focus, although my memory is slipping.  I don't think that I feel cranky but but it's not easy to maintain the same stability and sense of ease dropping out something as fundamental as eating.  My wife was yelling at me about something (over a call) and I yelled back, when normally I could just ignore it and let her have her say.  She's under a few levels of pressure too, and if it comes out in being cranky with me over something minor I should be fine with that.

Not much of a final retrospect take here, or new perspective.  It's possible that this practice could become really easy after one or two more trials, I just need to sort out if there is really any reason to keep trying it.  What if I am preventing cancer, suspending aging, improving internal organ function, and boosting my mental clarity?  Or what if every single potential health benefit isn't really happening?  I'm not even bringing up the "detox" theme, or letting my body drop off insulin resistance, which would be more of a concern if I was eating more sugar than I am.

Concerns about fasting; should people fast?

I've been thinking lately about whether I would recommend this to others or not.  I think not.  For people who feel like they need it, mostly for weight loss, or if they have a burning desire to mess around with how their body works, sure, it's fine.  For almost everyone it's just too disruptive, difficult, and unpleasant.  I kept saying that hunger wasn't much of a concern, and energy issues and loss of clarity only happened on 2 days out of 5, but that feeling of your body being empty of food never goes away.  Some people report feeling a related sort of euphoria, getting a high from it, but I seem not to.

One recurring theme in the Reddit fasting sub is communicating about fasting; many claim it's better to never bring it up, like that Fight Club rule about not talking about it.  The concern is probably over others taking it wrong, them being overly concerned, or you coming across as saying "woe is me!," when it's clearly an intentional personal choice, and definitely not a necessary one.  It absolutely has to become normal or it won't work.  

This includes impact to other daily life activities, beyond perspective and communication.  Few people could forego work or other activities for days to work through eating disruption, but I guess if someone has nothing going on laying on a couch for 5 days would work.  Even that defeats one of the main purpose though; if you drop normal activity level your metabolism will plummet, and weight loss won't occur to the same degree.

Related to other potential impact I slept like a baby, beyond getting up to drink salt water however many times, but then I tend to do that.  I might usually wake up to use a restroom and stay up for 15 minutes messing around online but my middle of the night insomnia days are behind me, since it's been a few years since kids have woke up frequently.  Storms wake my daughter, and then she wakes me up, but that's different, infrequent now.

It was cool that it seems like I could do longer runs if I try again, or probably could have this time.  Will that translate to feeling more energy on longer runs now?  I took an extra day off running after the fast because I felt soreness in my calves, maybe from disruption of normal recovery process, since I usually run a lot more than 4 miles in 5 days, often 6 miles in an outing.  But I'll run again and can check.  It would be nice if I didn't live in one of the hottest and most humid places on earth so I could check on that without disruption, the constant near heatstroke.  

I guess at a bare minimum I'll appreciate eating more again; there's nothing like fresh, plain, healthy food when you don't take eating for granted.

cheeseburgers and sweet potato, yam, and regular fries; that tasted good

the next day; chicken breasts are really easy to cook too
