Protein allocation

By definition LC is about dietary carbohydrate restriction. If you are reducing carbohydrates, your proportional intake of protein or fat, or both, will go up. While I don’t think there is anything wrong with a high fat diet, it seems to me that the true advantage of LC may be in how protein is allocated, which appears to contribute to a better body composition.

Zoinks! This short article is dense. I read each paragraph. Then slowly reread the paragraph, squinting slightly and turning each sentence over in my mind. It feels like there’s at least one actionable-item, (something to start doing, or something to stop doing,) in every paragraph. I’ve spent a lot of time in recent years trying to learn what I can about all the things in this article. It’s a beautiful assembly that backs up the thesis in the first paragraph, (which is quoted entirely above.)

Vitamin D

This might be the range most of us should expect to be in at an intake of 10,000 IU/d. This is the equivalent to the body’s own natural production through sun exposure.

There are other factors that may affect levels. For example, being overweight tends to reduce them. Excess cortisol production, from stress, may also reduce them.

…and some days this turns into a bit of a medical blog.

This is mostly a blog post for me, so the next time I search for Vitamin D I can find this article. When Vitamin D supplementation comes up, and I mention that I take 10,000 IU daily… people ask why? …and I cannot remember why. This article from 2010 is why; 10,000 IU is about how much vitamin D my body would make if I lived somewhere sunny and I was a life guard.

§7 – Exercise

(Part 7 of 13 in series, Changes and Results)

Exercise is not about weight loss.

Exercise builds physical ability and mental health.

For me, it began when I fell in love– with a bicycle.

The story of a boy and his bicycle

Long after college, way down in my downward death spiral, I bought a cheap mountain bicycle. Today, I don’t recall what possessed me to even want to buy a bike. I guess it just reminded me of the freedom I’d discovered when as a kid I first set out on a bicycle.

At the time, we were living in an apartment a short ride from a long park that followed a meandering creek. The park has long trails—some asphalt, some packed gravel—that follow the creek, and it has a few, short, side trails that almost resemble mountain biking.

I fell in love.

I fell in lust is probably more accurate.

I pedaled and pedaled. …and then I pedaled some more. …and then a lot more. I literally wore out that cheap, beautiful bike in the first summer.

During that summer we bought a mountain bike for my dad. He bought an hybrid bike for my mom. Then for a Christmas present, my parents and Tracy bought me a nicer bike. Whereas I was previously crazy about riding, with a new, better, lighter bike, I took things up several notches to addiction, and began riding the daylights out of everything.

I bought a “Mountain Biking Pennsylvania” book and started just heading out to ride trails from the book. Tracy bought a Cannondale when she changed jobs, and then things got out of hand—like Fear and Loathing in Las Vegas out of hand. In the end, I was directly responsible for 27 people going to a particular bike shop and buying bikes because I kept trying to find someone who had the bicycling bug as bad as me.

I pedaled on into the seasons. I commuted the short 2 miles to and from my office in rain and snow. I had studded snow tires for the winter. I replaced bike parts as they wore out, and modified the bike more and more until the bike shop owner, (at this point, a good friend,) finally said, “You know, there are other bikes.” It had never occurred to me that I could own more than one bike. he looked at me like the simpleton I was, “Craig, some people have so many bikes, they hide the newest ones from their wives.”

Re-learning to move

The story continues of course. (The new bike is named Beelzebub, and is the first bike I’ve ever named.) But this article is about “exercise”, not about my affairs with bikes.

In the midst of it all, I understood that it was all partly the runner’s high aspect. But also knew that I simply felt better the more I rode those bikes. Sure my wrists got sore, and I became a menace in the local park zooming around and around like it somehow mattered in the grand scheme. But in the process, my body was changing.

Much later I learned that what I had done was change my identity; changed the way I saw myself. I became the sort of person who would get up early on weekends to drive an hour to ride a bike all over some trail because it was “Trail number #87” in a book. I became the sort of person who learns about bikes, then learns about exercise, and then learns about glycogen storage in muscles.

At the very beginning of the bicycling epoch, I was building a lot of muscle. Well, a “lot” compared to the gelatinous blob of fat I had converted myself into after college. Muscle requires energy to build it and then some energy to maintain it. So in the beginning I got a small win on weight loss, just by adding muscle. As my daily caloric needs went way up, it halted the creeping weight gain.

Years later I learned that exercise is simply, generally healthy.

That sounds like a platitude, but it’s not: Even small amounts of exercise have out-sized benefits in your health and your daily mood. If I exercise just a little, (for example, 20 minutes of moderate walking,) then I sleep better that night, and every time I exercise I get a small psychological benefit.

The key point was the change in my mental health: Exercise made me feel better, and the better I felt, the more I wanted to exercise. Exercise didn’t make me lose weight: It improved my health, and I became the sort of person who weighs less. That sounds subtle, but it’s tremendously easier than trying to lose weight directly.

Compensatory adaptation

I changed my behavior (I added biking) and my body responded by adapting. (Compensatory adaptation from Ned Kock is a great, deep-dive.)

I added some muscle, changed some hormone levels and interactions, cleaned up some mitochondrial function, and other things improved. But soon (it was probably about a year) my body had adapted to where its new state worked well enough for the activities I was doing regularly. This is the famous plateau effect.

As I’ve mentioned, I didn’t realize this is what was happening (the plateau). I just bike bike bike bike biked all over everything. Meanwhile I was tracking things in my health journal, tweaking things here and there (sleep, moving dinner-time earlier, food choices, etc..)

How would you implement this intentionally? If you are even farther out of shape than I was at the start, I don’t suggest starting with biking. Walking is probably better, or maybe even swimming. Exactly what you do isn’t the point. It’s that you begin to exercise. Don’t to do in the sense that, “I have to go exercise now.” (This is why gym memberships generally don’t work as a New Year’s resolution.) Rather, you want to exercise just as something you do, and that will transform yourself into the type of person who exercises.

I am the type of person who…

Origin story

“I should lose weight. Specifically, I should lose some of this fat. …actually, a lot of this fat.”

Since I began my health tracking grids I had been regularly tracking my weight, building the habit of stepping on the scale every day. I’ve read several opinions that this is a bad idea. Because one’s weight can fluctuate significantly day-to-day, daily weighing can lead to “fear of the scale” and stress. I disagree. After stepping on the scale every day for about 10 years, it is now simply something I do. The scale shows me a number and I write it down.

One day I started reading more about physiology. How your body composition changes. How a strength building session increases muscle mass (duh) and that can make your weight increase in the short term. Suddenly, the scale going up can be a good thing.

…and then I wondered, “how much should I optimally weigh?”

http://healthcorrelator.blogspot.com/2016/10/virtual-paleo-summit-video-what-is-your.html

At the time I began this “waist/weight ratio project,” I weighed about 230 pounds and the “male, 5 feet 11 inches tall” medical guideline is . . . 175 pounds. What?! I would be ecstatic if I weighted 220. I’m not sure what I would do if I weighed even 215— I’d probably fall down in a stiff breeze.

So how exactly should one “optimize” weight? Why should I select any specific weight target? Why 175 (as medically recommended,) or 220 (college body!). What if my weight isn’t changing as I make healthy improvements– how do I track that? I began to think perhaps I should optimize health markers: Blood sugar regulation, inflammation markers, and triglycerides, and that is far more complicated than “step on the scale.”

Waist-to-weight ratio

One day, I read the following article. It’s deceptively short, but quite complicated and subtle. You should go read this very carefully before continuing.

Growth hormone may rise 300 percent with exercise

(Part 3 of 3 in series, Ned Kock's "Health Correlator")

Growth hormone stays flat for about 40 minutes, after which it goes up steeply. At around the 90-minute mark, it reaches a level that is quite high; 300 percent higher than it was prior to the exercise session. Natural elevation of circulating growth hormone through intense exercise, intermittent fasting, and restful sleep, leads to a number of health benefits. It helps burn abdominal fat, often hours after the exercise session, and helps builds muscle (in conjunction with other hormones, such as testosterone). It appears to increase insulin sensitivity in the long run.

Muscle loss during short-term fasting

(Part 2 of 3 in series, Ned Kock's "Health Correlator")

When the body is running short on glycogen, it becomes increasingly reliant on fat as a source of energy, sparing muscle tissue. That is, it burns fat, often in the form of ketone bodies, which are byproducts of fat metabolism. This state is known as ketosis. There is evidence that ketosis is a more efficient state from a metabolic perspective (Taubes, 2007, provides a good summary), which may be why many people feel an increase in energy when they fast.
