Exercise incentives

Stark picture making the rounds on Facebook lately:



Also, from this link:


I like to think I'm taking myself from the middle situation above, and becoming the bottom situation, adding more meat to myself, and that that's why my weight is hard to lose - meat weighs more. Size hasn't changed much over the last couple months.. so, I don't know what's going on exactly in this hexogenarian humanantigravitysuit. The first ten pounds came off the first month. It took 2 and a half months for the next 10 pounds to come off. Now I'm on my last ten. It might take 6 months to get those off, at this rate. Resting pulse has dropped, which I guess is healthy.. Slow though. Really really slow. And staying under 1200 calories for months and months and months is becoming ... well, I shouldn't complain - elsewhere in the world people are lucky to get one meal a day. Also, I'm pleased that my knees are in great shape. They handle the elliptical easily, remain painfree and fully bendy. Thank you, yoga that I did 40 years ago.

Over the hump

I'm pleased to report the worst time of year (in my existential experience) is done, finished:

1. Winter solstice has come and gone.
2. Christmas, that annoying, overly-social, intrusive sensory event, is over.
It drives me nuts, every year - but this year the place I've been going to daily to work out played loud Christmas music, mostly Kelley Pickler, country music singer who was an American Idol contestant a few years ago. That, plus all the usual - TV ads selling stuff, news reports about retailers feeling anxious, sparkly glittered-up bling all over everything, light displays - all of it made me deeply empathize with autistic kids who don't deal well with over-stimulation. Uck. 
3. My birthday, which was yesterday, passed by uneventfully and non-socially, and is now over with! Yay!

Anyway, back to point 2. for a moment; sensory overload got so bad at that little gym that I decided to skip last week. Plus I indulged in Truffles, eggnog, and Bailey's. Oh, and an omelette with cheese, tomato, and buttered toast. And I ate some delicious dates. Plus other holiday food, like stuffing. And I did not exercise, at all, for a week. Up by a few pounds. Back at the elliptical  this week. My stamina has increased - up to an hour on that thing - probably had to do with being able to watch uninterrupted, Australia, with Nicole Kidman, Hugh Jackman, Brandon Walters. It's not just interesting, it's well done, and a lot longer than most Hollywood movies. So, it has kept me going all week. I've watched large chunks of it for three days, and there are still parts I've yet to see.

Speaking of movies and cognitive distraction, I saw this awhile ago, How muscle fatigue originates in the head. Rather than blame the mesoderm (muscles) for fatigue, researchers are starting to look elsewhere, and have noticed how the nervous system inhibits muscle at various levels. In the brain, interruption occurs when the thalamus and insular cortex decide they have had enough. I seem to be able to shut out the din my thalamus and insular cortex try to mount, by watching 'Australia'. At least for a little while. Then I will need another movie I've not seen before.

From yesterday, The Fat Trap: It seems a bit depressing, but before I started all this business 3 and a half years and 40 pounds ago, I knew it meant:
1. I could never eat (completely) unconsciously ever again as long as I lived
2. I'd have to move a lot more, learn to sweat, learn to get my heart rate up, learn to like it. Somehow.

I had a long plateau in there, a couple years where my weight went up by ten, down by ten, but never went completely out of control. It was always around this time of the year, this nadir time. So, I'm pretty sure I can reach old age in fairly good shape, plus all the exercise is not just for weight loss but is good for a bunch of other stuff that has to do with health, brain function, etc.etc. Nowadays, I'm on the other side of the year's nadir, and (even with my dive off the wagon for a week) my weight is still lower than it has been in 15 years. I take heart from that.


I'm pretty sure, that like pain, obesity is biopsychosocial. It's not strictly a fault in character, or strictly about genes, or hormones, or strictly about bad habits (see picture). A calorie is a nebulous thing depending on what kind of human organism ingests it, what sort of food it comes in, and why it is being consumed. Everything exists in a multiply-leveled context, including a conceptual entity known as a calorie.

This notion, Fat may put the Hypothalamus on the Fritz, needs more work I think. It suggests that ingesting fat "causes" inflammation in the neurons around the hypothalamus, but Harriet Hall says, inflammation isn't always a bad thing.  Gumming up Appetite to treat Obesity proposes that special hormone-laced gum should be helpful. But I doubt there will ever be any kind of easy answer.

If I were to pick a single brain region to target, to investigate, to spin a theory around, it would be the suprachiasmatic nucleus (SCN). In fact, I already did. It has to do with sleep, with light levels, circadian rhythms, depression, hypothalamus, all sorts of things that are regulatory. The pituitary, part of hypothalamus, has to do with thyroid, which has to do with a bunch of hormonal and metabolically important outputs. I moved myself physically back to where my own humanantigravitysuit, myself as a human organism, grew up. Environmentally, climactically, photonically, my brain feels better here. This is what it remembers from its youth. The long slow dawns and dusks, bright fiercely blue skies, brilliant reflective surfaces, deep blue shadow. Sensorially, and socially, the surroundings are kinda dull, but frankly, I don't much care about lack of sensory or social stimulation; I'm used to it again; furthermore, I like to be by myself anyway, except on the internet, which is where I live, mentally, most of the time, so it doesn't matter. (Plus, I lucked out joining a weight-loss outfit that happens to suit me to a tee, and happens to ALSO be the only one of its kind - in the whole of Canada so far - imagine, humble little old Weyburn, Sask. has a one-of-a-kind thing that suits me to a tee, and I just happen to live here where it is. Amazing happy co-ink-a-dink.)

But back to causes of things, no one thing causes obesity, and everything combined causes obesity. Actually, the pursuit of "cause" in science (pharmaceutical science at any rate) seems to be a bit endangered in and of itself, according to Jonah Lehrer.

So, what then is "obesity"? Well, I would ask, what is a relationship that an organism of any mammalian multi-cellular sort has with its whole bio-psycho-social environment? What is stress? What is pain? What is learned helplessness? What is failure to move one's physicality sufficiently? All these things are "caused" by everything simultaneously, often overlap by a lot, and all influence each other. Mostly, we are biologically active bundles of multitudes of proteins without distinct boundary (other than those we dream up then feel compelled to defend fiercely), with a big microbiota with a big microbiome (especially in the gut tube) that tends to run our lives more than we care to admit, probably... all the single-cell critters of which evolve, have lives, reproduce and die according to what they get (what we give them) - to eat. It seems likely that they might have evolved ways of trying to harness us, their big vehicles that lumber forth to get groceries, so that they might get what they need in order to keep going. Not that we are obliged to feed them endlessly.. just knowing that the mammalian multi-cellular organism is more an ecosystem than it is a discrete entity gives me hope that I can explore, map, cultivate and tame my own - in the end, it's all I've got.  I live on a little mountain-top in there with a pretty good view. At least, my "I"-illusion does. It's a welcome bit of conceptual structure; another bit is provided by the idea, that biochemically their lives are completely controlled, attracted to, or repelled by chemical gradients, described in pretty good detail in Into the Cool. This knowledge makes me feel powerful, or at least, enough of an independent, detachable agent to be able to manage my own small corner of the universe, my body, to my own liking.

There is a psychological aspect to all this that must be mentioned - eating consciously means tracking what's ingested, counting calories, including those sweated off, and attending daily to all of it. This could lead to either OCD, or anorexia, or both. Yet, those are cognitive-behavioural constellations one must approach in order to lose weight/become healthier. What I've learned is that you can learn how to dance with these two things, but you must always be in the lead, never the one who follows. It's kinda goes against dance training in general, for females, but I seriously recommend remaining in complete control of everything, including short breaks like the one I just took.

Now I must go and drown my microbiota yet again in a whole bunch of vegetable matter, which I know it doesn't like much, and which will likely kill off some more of it, making evolutionary space for new kinds that might actually like vegetables. (AHHHHGH! Hulk destroy bad microbiota!)

Thanksgiving

Crude graph made in photoshop.
Happy-ness has more chance to develop/exist if red and blue lines are deliberately kept separated.

I'm pretty sure "happiness" isn't a feeling, or a mood or even solely a personality trait; I think it might just be a measure of the gap one can create between something called "stress" and something else called "capacity to regulate stress response".  So, happiness is an achievement, perhaps, for anyone prone to depression. Here's the reasoning, broken into sections:

STRESS
Stress is not a fixed thing. It's a relationship one's nervous system has with existence.
Some stress is necessary or the brain will just sit there and do nothing - it won't learn. It won't remain flexible and adaptive.
Too much stress will make it adapt badly. It will impair the brain sooner or later.
Stress is described as an upside-down "U" function - an optimal amount helps one navigate life, if not with pleasure, at least with a sense of success rather than defeat. (I've read and learned much from all the articles in  Nature Reviews Neuroscience: Focus on Stress [2009])

One can manipulate, if not stress itself, stress-ors.. mostly by avoiding them or reducing them or eliminating them. What might be some stressors easily eliminated? Oh, most TV shows, smoking, drinking alcohol, etc.
Likewise, hanging around people who belittle you in any other way, or do not enhance your mental or physical life, is counterproductive, best avoided I find, at least for me.

E.g., I find boredom very stressful.


Freedom from the stress of boredom
If left to myself, I'm not bored. I can find things to do and read and think about. I can watch my brain machinate its way through perceived conundrums. I can plan (although I don't really like to be attached to plans, because plans have to fight a lot of external resistance and get changed as a result, much of the time) and organize (something else I'm not all that attached to) and learn (something I never get tired of) and think (about anything, everything) and write (about anything, everything). Or just breathe and not have to do anything with my brain. Unencumbered.

Social stress, boredom
I find it immensely stressful to be around people I consider boring, and I find most 'socializing for the sake of socializing', boring, so I am mostly a solitary hermit. I've never married or had children, because I find routine (outside my own easily changeable personal routines) extremely boring; the very thought of harnessing myself into a small group of other human primates forever dependent on my personal involvement with them, freaked me out completely as a young woman, so I just never went there or did that.
Now as I look back on life from the ripe old age of 60, I appreciate the instinct that kept me unattached, and the way I chose to combat and navigate but not give into competing instincts, such as wanting to belong somewhere or find 'lasting romance': I did live with someone for three years (ran a simulation of what marriage might be like); nice man, satisfying relationship in most of the important ways (from the perspective of a 22-year-old healthy female), but in the end found it boring and therefore stressful.
Having to continuously adapt to other peoples' needs and wants in exchange for 'belonging' to a domestic arrangement was something I knew intrinsically that I'd never ever be able to pull off successfully. It never looked like it would be a good bargain. I had instinctive fear of the avalanche of expectation that surrounds ordinary social domesticity. My nervous system's threat detectors have been allergic to social norms, and have therefore sounded pretty much continuously, all my life.

Gratitude
It's Thanksgiving here in Canada; it seems appropriate to include the fact that every day of my life I'm grateful that since I had to come into existence in the first place, with such strong personal proclivities in the second place, it was into a culture and era that permitted me, a woman, to retain control of my own physicality, in particular that physicality residing below the waist (...and enjoy it too, when/if I wanted..).
Most important has been social autonomy. I was born at a time when I learned I had the right to bodily autonomy, enjoyment of physicality, to wear whatever was/is comfortable, sensible shoes, no make-up. Or, on the other hand, the right to dress like a female caricature if I felt like it. Which I did sometimes, mostly in order to escape notice, to blend in, feel more invisible and be able to 'compete' successfully. Not that I ever won any prizes for looks, or captured any trophies of any other kind (a vision comes to mind of a marriage partner mounted like a deer head over the mantle, but more likely a spouse would be sitting on the couch, quite alive, watching sports no doubt..)
In most cultures on the planet, girls are groomed from birth to adapt to the fact that they are destined to become someone else's reproductive livestock, uteruses with arms and legs, that their humanantigravitysuits are not strictly their own - that instead, they do not have any right to enjoy ownership of their bodies, specifically from the waist down, ever, and usually not the space between their ears/above their eyes, either.
My family gently hinted at this, but never did I feel coerced toward enacting such a role. My life was mine to live however I chose - my body, all of it, was mine to do with as I wished, and the culture of the 1960's and 70's that surrounded me as an emerging biological woman made it real.
For this freedom, which I realize now is a true happiness, I'll be forever grateful to my mother. I think my dad probably had more restrictive, more male-biased, protestant-tent-religion-based, traditional views on the matter, but my mother, a lapsed catholic who never displayed any ambition beyond keeping a home and raising a family, somehow still managed to keep enough space open for me to run away through, out to 'freedom from family'. She has probably never really reflected on why she did that. I certainly have disappointed her in almost every way imaginable from an interpersonal or social point of view; I'm pretty sure she likely expected her oldest daughter to heave to eventually and contribute my share to the planet's overpopulation problem; but I never did - instead I took total advantage of the opening out into the brave new feminist-hardfought-and-won world of female autonomy, and sailed away.
On the other hand, it may have been that she just didn't care; I think the fact her first-born happened to be female, not male, disappointed her, and so it didn't really matter to her what I turned out like, as long as I didn't do anything too egregious like end up an unwed mother or in jail. Still, I remain grateful that she wasn't as overbearing as she could have been.
I did not copy her life, only half her genome. During all the years she spent on care and feeding and cajoling and 'training' (as she called it), and encouraging me at schoolwork, I also absorbed years of watching her be content with cooking/baking/cleaning/laundry/hanging clothes out on a clothesline/enjoying herself in the evening by knitting/crocheting/sewing/doing petit point/etc., reading "ladies'" lifestyle magazines (the only reading material that ever made its way into our family home, beside my dad's Commonwealth newspapers), and.. found it utterly boring. I repaid her maternal investment by not reenacting her existence.
Some judgey little part of myself, some mirror neuron biological part, no doubt, feels (weirdly to me) bereft, and despises me for what it considers selfish ingratitude, based on my having not replicated family life. But the rest of me forgives myself and moves along, knowing full well it would never have had a chance to surface at all, had things not gone the way they did. Plus, I spared all my unborn children the fate of having a mother who would have found child-rearing utterly boring and probably intolerable. I spared them the chore of existence itself. I spared them having to put up with someone as capricious and depressive as I, from being their mother. I saved myself (and them) a lot of stress. Furthermore, I made a colossal forward payment on my own carbon footprint by not replicating any more people.

CAPACITY TO REGULATE STRESS RESPONSE
Learning how to increase this has also been found to help to widen the proposed happy-gap.
It's something I'm finally getting around to, now that I know how crappy (opposite of happy) life can feel when this capacity diminishes. The single biggest ingredient of maintaining this capacity is regular exercise, so I'm led to believe.
Now, I haven't been exercising on a regular basis long enough to find out how I and me and myself will adapt to it - for now, it's still a stressor and therefore has not widened any discernible gap. But  I do have faith it can, and will, based on a bunch of stuff I read about the endless benefits of exercise on physiology and brain health, and that it's never too late.
For the moment, I'm content that I finally discovered a place in which I can exercise with minimal psychosocial stress from exercise itself. I mean, there's still the issue of having to be in the same room as a bunch of other women, and having to put up with music I don't enjoy (this is Weyburn; country music about neon signs and green tractors etc. is mixed up with Katy Perry and Lady Gaga; on the plus side, it's a women's gym, so I have not noticed any loud head-banger music).  In spite of minor distractions (music which I could avoid if I wanted by using an iPod or something) it feels like this is some sort of turning point for me, that someday soon I could actually enjoy exercise (i.e., not find it boring, or nociceptive), and instead of going through life just reducing stress at one end, I could increase the happy-gap from the other end too.
