Stuff I Learned - Week #10

A recent article on CR
A friend of mine once described his tendency toward ADHD as like being a ferret on crack. While I have yet to directly observe a rodent smoking a Schedule II controlled substance, my friend's metaphor immediately created a mental image that's endured in my mind.

I have a pretty strong tendency toward ADHD. On the rare days that I find open space in my schedule, I often wander from task to task, like a vagabond in my own home. It's only through diligent mind-training (meditation) that I've reined in my random-walk mind in order to accomplish some of the goals that I've set for myself.

Even though I've largely learned to work with my ADHD tendencies, every so often I'm still reminded of my tendency toward this cognitive Brownian motion. Just the other day, I was on the PubMed website looking up a neuroimaging study on people with joint laxity (fascinating, BTW). While on PubMed, an article on calorie restriction (CR) appeared in the sidebar. I've been interested in CR for awhile, and quickly found myself shifting my focus from fMRI studies of the amygdala to discussions of longevity and age-related decline.

The non-ADHD subject of this blog
I've long been fascinated by the increased vitality and lifespan of animals that are fed reduced calorie diets. While the evidence is pretty strong in support of CR benefiting the health of animals (including worms, flies and rodents), the evidence supporting CR for humans is pretty scant.

To help bridge the gap in understanding how humans (and not mice!) may respond to CR, researchers at the University of Wisconsin are running a long-term study of monkeys fed CR diets. While the study is far from complete, the initial results are very encouraging. I think it's too early to draw any conclusions about humans, though the CR monkeys seem to be living longer and healthier than their heavier (but not obese) comrades.

As in many things science, there are different schools of thought on CR. Some studies make it sound like CR is the for-sure, next best thing, whereas other studies suggest that the CR benefits may be limited in humans. In a future blog I'll talk more about how I've adopted some (but not all) CR ideas into my personal approach to nutrition, but for now, I'd like to leave you with my favorite words of advice on food.

  • Eat Food
  • Not Too Much

Have a great week, and thanks for reading!

I'm curious what kinds of calories / foods were consumed in this / these studies.

30-years in the Driftless

-
Image
Thirty years ago I inadvertently landed in Wisconsin's Driftless Region. Lured by the call of Yoga, community and sustainable agriculture, I found a place that I have called home for the better part of my life. Over Memorial Day Weekend 1994, I made the somewhat impulsive decision to relocate to Blue Mounds, WI; a decision I have not regretted. I was drawn to the Driftless by the 1994 Memorial Day Teacher's Hang Out Weekend The Spring of 1994 was a pivotal time in my life. I'd recently graduated from college, and with a group of friends, co-founded the St. Paul Yoga Center . Despite the path that was unfolding, I felt an itchiness to explore and reevaluate my emerging adult life. I yearned to live closer to the land, and simultaneously felt that the Yoga I practiced and taught was detached from the natural world. The call of the 4th Annual Memorial Day Teacher's Hang Out Weekend could not have come at a more opportune time. It seems almost quaint, now, to receive an inv...

100,000 Miles on the Tesla

I've been a car guy  my entire life. Toy cars were my childhood obsession. As a teenager, I somehow took obsessed  to the next level, and literally memorized tracts of my favorite auto repair manuals. (Yes, I had favorite repair manuals). I slightly downregulated these obsessions in my middle years, though I was still keenly aware of the cars around me, gimbaling to lock in on an unfamiliar model or automotive rarity. This Tesla Model Y has been on many roadtrips. When the Tesla Model S came out in 2012, I was swept off my feet by its aesthetics, performance and the underlying technology. Initially Tesla sightings were infrequent, and I employed the unproven technique of staring/not-staring in an inept attempt to avoid stalking the early adopters. Within a few years, however, the more-affordable Model 3 opened the sales flood gates, and it suddenly seemed like Teslas were everywhere. The "Idiot Book" was my favorite repair manual. By the time the Tesla Model Y (the small ...

Aging & Inflammation

Aging well is largely about managing inflammation. You will likely feel better and have more energy if your baseline levels of inflammation are lower, and will likely struggle more with aches, pains and low energy when your baseline levels of inflammation are higher. Managing inflammation is essential to aging well, and requires more than anti-inflammatory supplements and down time . Reducing baseline levels of inflammation requires the strategic application of inflammation. Known as hormesis , regular applications of inflammation can lower baseline levels of inflammation. To some small extent, that which doesn’t kill you may well make you stronger. The trick is getting the dose just right, as the dose of inflammation either makes the poison or the medicine. Yes, this is an eBike. I adjust the level of assist to maintain the just-right challenge. Exercise, particularly cardio, is inflammatory. This is among the many reasons why doing cardio is an essential element in aging well. In th...
